Patent holder RICHTER GEDEON VEGYÉSZETI GYÁR R. T., BUDAPEST (MLR) (54) Plant Growth Regulator 1

BACKGROUND OF THE INVENTION The present invention relates to a plant growth regulator used in particular to promote crop growth in agriculture.

Known plant growth regulators can be divided into two groups: natural origin and synthetic. The plant growth promoters of natural origin include auxins, gilbberellins, and cytochinins, and plant growth retardants of natural origin are abscine acids, first described in 1965 (R. Wegler: Chemie der Pflanzenschutz - und Schadlingsbekamfungsmittel, Springer VerlagBerlin, Heidelberg , New York, 1970, pp. 399-429). The effect of "auxins" on plant growth was observed in 1928 by F. W. Went (Rec. Trav. Bot. Neerl. 25 (1929), 1). The compound was isolated by 1934 by F. Kogl and identified as O-indolyacetic acid (Ber. Dtsch.Ges. 1935 A, 16). Several years later, the first publications on the effect of phenyl- and α-naphthylacetic acid as growth regulator regulators, preferably their nitriles and amides, were found, but herbicides were not yet mentioned (German Patent No. 716,342; PW Zimmermann F. Wilcoxon: Contrib, Boyce ThomsonInst., 7, 1935, 209). Phenoxyalkancarboxylic acids and their derivatives as selective herbicides were known as a result of the work of English, American and German researchers in 1941 and 1945. Since then, these compounds have been used, which also form a major part of the herbicides produced. In recent years, the effect of individual inorganic salts on plant growth has also been investigated. Thus, polyphosphate and polyphosphoric acid esters, especially mixtures thereof, are known from DOS 1932 198 as plant growth agents.

Described in the description is the desired effect on the growth of unspecified polyphosphate blends as well as the effect of cerium nitrate and polyphosphate and cerium nitrate mixtures, but only 0.1 g of heavy lettuce seedlings and 1.81 g of heavy saccharides are exemplified. However, no further details are given in the said specification, in particular the changes resulting from the development of the germ and the effect of the composition on the developed plants. DE-A-2 259 998 discloses a composition for the growth of hops which simultaneously reduces fungal-mediated diseases, increases the content of α-acid in hops and improves odor. All this is accomplished with aluminum chlorate and water-emulsifiable oil. However, there are no data on the desirable effect of aluminum chlorate on the growth of hops.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a novel, commercially available, excellent plant growth regulator, which can be used in agriculture.

The invention is based on the discovery that acid sulphate, acid sulphite, dithionite, sulphate, chloride, phosphate, moderately acid phosphate, acid phosphate, carbonate carbonate, nitrate and sodium thiosulphate, optionally potassium, moderately acidic magnesium phosphate, and zinc sulphate, or mixtures thereof (hereafter referred to as plant growth regulating salts), have a plant growth effect and, furthermore, a substantially increased germination rate, green weight and plant yield.

The essence of the plant growth regulator of the invention, such as rape, oats, barley, especially wheat, corn, soy, sugar, potato and alfalfa, is that it contains 0.001 to 99.5% by weight of the active ingredient. % of at least one salt of a selected group comprising sodium or potassium normal or acidic sulfuric acid, sodium sulfite or potassium dithionite, sodium or potassium dithionite, sodium or potassium chloride, normal, sodium or potassium phosphate, normal or acid; sodium or potassium carbonate, sodium or potassium nitrate, sodium or potassium thiosulphate, magnesium phosphate and zinc sulphate, in association with carriers, fillers, diluents and / or other auxiliaries.

Of the above-mentioned active substances, the following are particularly effective: sodium sulphate, especially in the form of monohydrate, acidic potassium sulphate, sodium sulphate and potassium sulphate, although sodium sulphite. Thus, compositions containing such substances are preferred.

In the first place, the plant growth regulating effect is understood to mean plant growth as well as acceleration of the inflorescence and maturation. By increasing the germination, it is not only possible to develop roots and stems more quickly, but also to reduce the smallest sprout temperature, i.e., previously, the sieve, thereby also achieving earlier harvest. These indicate substantial technical advances in the use of the compositions of the invention in agriculture.

The use of the compositions of the invention in agriculture is understood here in the broadest sense of the word: for example, all uses in the field of farming, in particular plowing, forestry, vegetable and fruit cultivation, horticulture and seed granulation.

Plant growth regulating salts of the present invention may be formulated together with said carriers, fillers, diluents, and / or excipients into various solid, liquid, or gaseous formulations for use in agriculture, including landscaping. Different suitable preparations can be prepared according to different applications.

The solid preparations may be preferably a powder, in particular a wettable powder and / or a dispersible powder (spray powder), grains, granules, pastes, granulated seeds or in agriculture or, in particular, in particular, the use of a usable foil.

Liquid preparations may be solutions, in particular immediately sprayable solutions, both aqueous solutions and solutions in organic solvents, or as oils and miscible oils, as well as dispersions or suspensions, in particular aqueous suspensions, aqueous or oil emulsions or inverts. emulsion.

The gaseous preparations may preferably be aerosols.

For example, the powder formulations may be prepared by mixing one or more of the plant growth regulating salts of the invention with one or more of the above solid carriers, followed by one or more wetting agents, or dispersing agents.

The granular or granular preparations can be prepared, for example, by dissolving one or more of the plant growth-controlling salts of the invention in a solvent, preferably water, and applying the solution to the surfaces of the particulate matter, such as porous, in the presence of a binder. grains, for example pumice or clay (attapulgite, non-porous mineral grains, such as sand or loamy soil, or organic granules, for example, black ground unbored tobacco stems, and then optionally dried. Further, granular or granular preparations may be prepared by In order that the plant growth salts of the invention are compressed in the presence of lubricants and powders with mineral powders and the obtained compacts are crushed and sieved to the desired size, the molding is preferably dried or wet according to a preferred variant of the preparation of granular or granular preparations. , Processed grain, if desired, granulated.

Aqueous solutions, dispersions, suspensions or emulsions can be prepared by dissolving the plant growth-controlling salts of the invention in one or more solvents, optionally including wetting agents, dispersing, suspending and emulsifying agents. The mixture obtained is diluted with water, which may also contain wetting and dispersing or emulsifying agents.

The immediately sprayable preparations can be prepared by dissolving the plant growth-controlling salt of the invention in water, which preferably contains a wetting agent, or in a medium or high boiling solvent, preferably boiling above 100 ° C. .

Mixed oil preparations can be prepared in such a way that the plant growth-controlling salts of the invention are dissolved with the addition of an emulsifying agent in a suitable solvent, preferably with a slightly miscible water or finely dispersed therein.

Invert emulsions can be prepared by emulsifying the salt suspension of the invention with water before or during spraying in a spray apparatus.

Aerosols can be prepared, for example, by mixing the plant growth-controlling salts of the invention, if desired, in a dissolved state with a blowing agent liquid, such as a freon-type liquid. Preferably emulsion concentrates, pastes and powders with a high active ingredient content are used to prepare the aqueous forms. Before use, they are diluted with water to the desired concentration. These concentrates are prepared in that they can be stored for a longer period of time and are not to be prepared for a long time by homogeneous and sprayable spraying machines after dilution with water. Concentrates typically contain 10 to 85 wt. preferably 25 to 60 wt. % active substance. The active ingredient content of the aqueous preparations is preferably 0.001 to 3.00% by weight. however, it may also be higher or lower for special applications.

According to a particularly preferred embodiment of the invention, the seed film is provided with a regulator of the composition according to the invention, which is incorporated or applied to the seed or the surrounding area. If the plant growth regulator is applied to the seed, this is incorporated into the foil. It is known that, in horticulture, but also in other areas of agriculture, sowing is facilitated and the seed is evenly distributed and the line is evenly handled, but is provided in a waterproof foil and these strips (optionally). bundles), which may optionally contain seed grains in multiple rows, are then introduced into the ground. The films may be of any water-soluble material inert to the seed, for example polyvinyl alcohol. They are merely required to disintegrate, or dissolve, the non-damaging agent and the ground moisture. The particular importance of crop growth-regulating salts of the present invention is that they increase the germination of the seed or, in the first instance, promote the growth of the plants to be grown. In this specification, for growth regulator regulators according to the invention, which contain one or more of the specified active substances alone (plant growth regulating salts), or which contain carriers, fillers, diluents and / or auxiliaries, in addition to the active ingredient (s). preparations), as well as for the film foil, uses the collective name "compositions of the invention". In the compositions of the invention, the concentration of plant growth regulating salts can be varied within wide limits. Depending on the type of preparation and the intended use, the concentration is usually 0.01 to 99.5% by weight. If the composition is used in very low volume doses, the growth-regulating salts of the present invention contain only a small amount of additive, with the active ingredient content preferably being between 90 and 99.5% by weight. are applied by very finely distributing devices or particularly preferably from aircraft. Typically, the concentration of the diluted formulations is 0.01 to 20% by weight. and in the case of concentrated preparations 20 to 98% by weight. For example, in the powders used, the active compound concentration can be, for example, from 5 to 80% by weight, preferably from 10 to 60% by weight, for example from 5 to 70% by weight, preferably from 10 to 50% by weight, in emulsifiable concentrates, and for example 0.5 to 10 wt.%, preferably 1 to 5 wt. The compositions according to the invention can be used as spraying, dusting or spreading agents, as well as coatings (seed auctioning), seed films, potting agents and amacating baths, the kind of preparation being in any case chosen to conform to the conditions of use. When the plant growth-controlling salts of the present invention are used, the salts or preparations prepared therefrom are applied to the soil, seeds, plants or plant parts in a manner known per se. For seed treatment, the seed may be coated, for example, with the salts of the invention, the plant growth regulating agent, optionally in combination with a carrier; the plant growth regulating salts may also be applied together with the surfactant compositions and optionally the carriers to the surface of the axis. In the latter case, the plant-regulating salts of the invention may be mixed with surfactants and carriers, the mixture moistened with some water and the suspension then treated with the seed.

The special treatment of the seed is the auctioning of the axis. For example, this treatment can be carried out by treating the seed in a draining vessel with a binder solution (e.g., sodium carboxymethyl cellulose). Then, the powder coating is sprayed onto the surface of the sprinkled seed. For example, the paprika can be drained with a mixture containing 5 - 50 mmol of urea, 1 - 10 mmol of KH 2 PO 4 and 5 - 50 mmol of KHSO 4 for one grain. When using plant growth regulating salts according to the invention, it is also possible to apply salts mixed with sand, earth or the abovementioned carriers, or surfactants, to the powder form when sowing seeds into the soil.

The plant-regulating salts of the invention can also be applied in the form of aqueous solutions containing surfactants and / or powder carriers on or before the sowing, during or after sowing. The use of the salts of the invention in agriculture can also be accomplished by applying the salt-containing composition, for example, by spreading, spreading or spraying a plant or their living space or individual portions thereof, e.g. , flooding or introducing rest.

The compositions of the present invention are equally suitable for controlling plants with single-stem leaves. The repair may be carried out prior to sowing the seed, before germination, eventually emergence of the plants, after germination, eventual emergence of the plants, or incorporation into the soil.

The pre-sowing application is understood to be the application or treatment of the composition according to the invention prior to sowing the seed or the soil.

The term pre-application refers to the introduction or treatment of the composition according to the invention, for example by spraying before the germination of the plants, i. when the seed with its sprouts has not yet broken the soil surface.

By additional application is meant application or incorporation of the composition according to the invention after the plants have been sprouted on or into the treated area, for example individual parts of the plants or on the soil, if desired.

It has been found that the compositions according to the invention exert their effects on plant growth, especially in the case of maize, corn, sunflower, alfalfa, sugar beet, rape, soybean, rice potato.

The amount or dosage of the compositions according to the invention depends on a number of factors, for example the type of plants to be treated, their condition, the surrounding plants, the use field, the type of growth regulating salts used, the season of the year. In this regard, the optimal dosage is determined empirically in each case. Usually 0.1 to 50 kg of active ingredient per hectare are used.

Depending on the type of use (for example, o-soda treatment, foliar treatment, incorporation into the soil, or application to the soil surface), the compositions according to the invention are used in various concentrations. an active compound content of 0.005 to 1% by weight (0.5 to 10,000 ppm), preferably 0.001 to 0.1% by weight (1 to 1000ppm), and dilute pre-application and pre-application sprays are used. the parates in a concentration of 0.1 to 3.0% by weight, preferably 0.3 to 1% by weight, can also be used without incorporation into the soil according to the invention when introduced into the soil, in the treatment of seeds and in plant films. The invention is further illustrated by the following non-limiting examples

A wettable powder was prepared from these components: 25 g of sodium sulphate monohydrate, 65 g of kaolin, 10 g of alkylaryl polyglycol ether. From the sodium sulphate monohydrate, a concentrated aqueous solution was prepared which was added to the alkylaryl polyglycol ether with stirring. The solution was sprayed onto kaolin, whereupon the mixture was homogenized in a mixer and then milled to the desired size. Thus, a wettable powder formulation was obtained containing 25 wt. %. The preparation could be diluted with water to any concentration. EXAMPLE 2 The following ingredients were mixed together to form an emulsion concentrate: 20 g of potassium sulphate, 17 g of nonite (40% dioctyl sodium sulphosuccinate, 3 g of calcium dodecyl sulphonate, 45 g of ethylene dichloride, 15 g of an alkyl benzene solvent mixture (" AROMASOL " H).

The mixture was stirred to disperse the components. EXAMPLE 3 The following ingredients were mixed together and milled to produce a seed treatment composition: 80 g of sodium sulfate, 2 g of mineral oil, 18 g of kaolin. EXAMPLE 4 A concentrate of this composition was prepared to produce a spray suitable for the treatment of the axillary and leaves: 15 g of sodium sulfite, 80 g of water, 5 g of octylphenyl lactaglycol ether.

First, sodium bicarbonate was dissolved in water, followed by octylphenyloctaglycol ether.

Depending on the application, the concentrate was diluted to the desired extent. Example 5

From the above table it is clear that none of the test salts are harmful to the test plants and that the salts used according to the invention are themselves alone at 20 kg / ha phytotoxic. To determine this difference, the maize plants treated with a single dose of 10 and 20 kg / ha, sodium sulphate monohydrate were cut off (24th February 1975) and their green weight was determined. the weight of plants treated with 10 kg / ha was 15 ° / o, treated with 20 kg / ha and 50% higher than the green weight of untreated plants.

Examining the effect of additional application

Test plants Untreated (blank)

In Example 9, maize (Zea mays), barley (Hor-deum distichon), sugar beet (Beta vulgaris) and rapeseed (Brassica napus) were sown in flat plastic molds. 10 or 20 kg / ha of sodium hydroxide sulphate monohydrate, respectively, and a blank sample with only water was applied in parallel, and the treated and untreated plates were stored in a greenhouse at 20-22 ° C. The green weight of the plants was determined and expressed as a percentage of the green weight of the untreated test, which was 100%, and the results are summarized in Table 7 below.

Of the values shown in Table 9, the growth regulating salts of the present invention have a superior effect on water (blank) in all 4 plant species tested. Example 13

A test in the open air 144 m2 large plot, whose soil consisted of sand clay containing 2 to 3 wt. % of organic matter, which was sown with lid grains, was harvested after harvesting in the following manner: plowing with a plate plow and then spinning with disc and rack gates. Then the maize was sown with a six-row seed drill. With 800 1 / ha of water, the following regulating salts were sprayed in the pre-application: 10 kg / ha of monohydrate acidic sodium 5 kg / ha of acidic sulphate of potassium 10 kg / ha of acid sulphate 5 kg / ha of sodium sulphate 10 kg / ha of sulphate sodium-free (without treatment (plot D-7) (plot D-2) (plot D-3) (plot D-4) (plot D-5) (plot D-6)

At the end of the growth period, maize height was measured and then harvested with a machine type E-280. The plant height and average yield were determined and expressed in the following Table 10 in relation to the untreated plants of the blank, or to the untreated plots given the value of 100. 50 kg / ha sodium sulphate monohydrate (plot D-1)

As observed by plant phenomena throughout vegetation, no plant growth promoters are phytotoxic. The corn treated on parcels, especially treated with potassium sulfate and sodium bicarbonate monohydrate, had a greener bar. Example 14 144 m 2 (9 m X 16 m) large parcels were treated as described in Example 13, then silage maize sowing and 4 weeks crawl application were sprayed with these plant growth regulating agents (John Deer spraying device and amount water = 800 1 / ha): 50 kg / ha of sodium sulphate monohydrate (plot Fl) 10 kg / ha of monohydric acid sulphate 5 kg / ha of acid sulphate of potassium 10 kg / ha of acid sulphate 5 kg / ha of sodium sulphate 10 kg / ha sodium sulphate 5 kg / ha of sodium sulphite acidic acid 10 kg / ha of acid sodium sulphate blank (no treatment (parcel F-2) (parcel F-3) (parcel F-4) (parcel F-5) ( parcel F-6) (parcel F-8) (parcel F-9) parcel F-7)

At the end of the growing season, the corn was measured and then harvested with the E-280 silage harvester. The average plant height and the average yield of the individual plots were determined, and the following table 11 shows the ratio of the blank to the plants, or to the blank plot, giving a value of 100.

No phytotoxic symptoms were observed. Example 15

Investigation of the effect of application in the run-down

In the manner described in Example 10, the effect on the growth of plants with NaHSO3, NaHSCl3, Na2SO4, KHSCD, KHSO3 and K2SO4 salts was tested. Maize (Zea roays) was used as the test plant.

Silica sand was filled into flat plates of 32 X 27 cm plastic. The seed was coated and then covered with a 1 cm thick layer of river bank for uniform germination. The dishes were stored in a greenhouse at a temperature of 20-22 ° C. Plants were sprouted, ie 20 days after sowing, in a manner described in Example 9 with plant growth regulating salts in an amount of 10 kg / ha. After 15 days, the plants were cut, the green matter determined and expressed as a percentage of the green weight of the untreated control plant. The results obtained are summarized in Table 12 below.

As can be seen from the table, the substantial green weight when using plant growth regulating salts increases, especially when NaHSCU is used. . H2O, K2SO4 and KHSO3. Example 16

Examining the effect of pre-application

In the manner described in Example 9, the effect on the growth of KHSO3 and K2SO4 salts was investigated. Zea mays were used as test plants. The plants were treated with 10 kg / ha of KHSO3 and K2SO4 and discarded after 20 days. The green weight was determined and expressed as a percentage of the green weight of the untreated controls. The results obtained are summarized in Table 13 below.

Investigation of effect in aquatic cultures

The effect of NaHSO4, NazSO4, KHSO4, K2SO4 and KCl salts on plant growth in aquatic culture (hydroculture) was investigated. Two test plants were used as test plants, namely F481 winter wheat and MV SC 380 maize, followed by a two-birth plant, soybean (additive). The tests were carried out with water from water, or with maize, also with a water supply with Hoagland solution. The magnesium solution was used in a quadruplicate dilution since, according to experimental experience, the uptake of ions by germinating plants and ions into the shoots is optimal.

The ion content of the diluted Hoagland solution and tap water is shown in Table 14 below.

Chicken and soybeans were stored in Petri's mugs filled with tap water, where they were germinated for 24 hours. Individual plants of the same degree of development were chosen. 30 wheat plants, 20 corn plants and 16 soybean plants were placed on a stainless steel mesh for 400 ml of solution. The plants were kept in dark water for 24 hours, then the water was replaced with a test solution. and the plants were stored in a thermostat with light. Wheat and soybean were set up by two experimental series, for maize three experimental series. In the first two experimental series, water-regulating salts of 10 or 100 ppm were added to the feed water, and only four times diluted Hoaland-100ppm salt solution was added to the maize. All experimental series were repeated twice in parallel. Wheat was harvested on the seventh day, maize and soybean de- 58 12 50 52.5 7.8 16.0 sate. In the case of wheat and maize, fresh weights of shoots and roots, as well as the length of the shoot, were found. In soybean plants, the weight of the stem and the leaves were also determined by the weight of the shoot and root. The dry weight of the plant was also determined for maize.

The dry weight of the maize shoots grown in tap water was 10% of fresh weight, and 7% of the fresh weight in mead salt plants. Thus, the relative water content of the others is higher, but at the same time the dry weight yield of the larger green mass is 30% higher than that of tap-water plants (the dry weight of 20 shoots was 1 g for tap water plants, on salt solutions was 1.3 g).

Illumination intensity was 5000 lux at all experiments, temperature 21 to 25 ° C. The significance of the treatments resulting from the treatment was the Student Tester-sample. The results of the experiments are summarized in the following tables 15, 16, 17, 18a, 18b.

Significant supportive effect on the weight of wheat shoots and maize shoots also on the 10ppm salt.

Such sodium salts provide an increase in the weight of the shoots and the root of the wheat and the weight of the soy leaves. This effect is significant when using 100 ppm.

If a balanced nutrient solution is used as the external solution, it also appears to increase the weight of the shoots as significant. Example 18

The procedure described in Example 15 was followed except that KCl, KH2PO4, K2CO3, Na2S2O3 and NaHCO3 were used as active ingredients.

The results obtained are summarized in Table 19 below by untreated controls.

As can be seen from the table, a significant increase in green weight is obtained using salts regulating the growth. Example 20 The effect of NaHSO 4 is examined in this example. H2O and KHSO4 for germination and vegetative growth of winter wheat.

The wild-type tests were carried out on loamy soil with moderate potassium content (19.5 mg K2O / 100 g). The pre-culture of wheat, after harvesting, was plowed 18 centimeters deep and then fertilized by NPK (nitrogen, phosphorus, potassium) in a 4: 14: 14 ratio of 4 q / ha. Then the land was drag-on.

The winter wheat of the Caucasus species was used for the experiment.

It was stained in 200 g / q FUN-DAZOL 50 WP (commercial fungicide; effective 26.2 34.6 17.4 26.2 36.3 fabric: Benomyl, i.e. 1- (butylcarbamoyl) benzylidazole-2- γ-carbamate), optionally in combination with 200 g / d of FUNDAZOL 50WP and 50 g / q of NaHSCU. H2O, KHSO1 and Na2SO4.

Pickling was carried out in a sloping cauldron at 20 min -1 for 20 min. FUNDAZOL 50 WP (200 g / q seed) was diluted with 3 liters / q water and sprayed onto the seed surface with a diluted pickling agent. In the combined treatment, FUNDA-ZOL 50 WP (200 g / q seed) was first diluted with 2 liters / q water. NaHSO4 salts. H 2 O, KHSO 4, optionally Na 2 SO 4 were dissolved in 50 g // q seed in 1 l / q water seed and the resulting solutions were dosed to the RUNDAZOL slurry. The boiler speed and the 0-investigation period were identical.

Seeds treated or treated according to the invention were sown on October 25 with a 24-line 27 196329 sowing machine of type A 761. 300 kg of seed was used per hectare, the sowing distance was 10.5 cm. 9 days after the plants were raised, plant height was determined. The 14th hole was evaluated for germ per running meter row (see table). On 12 February next year, the test parcels were treated with nitrogen-treated fertilizer (4 g / ha, nitrogen content 34% by weight). On April 2 and May 6, wheat growth was evaluated.

After treatment, the tubers were inspected, and the sprouts (eyelids) were found to be significantly damaged.

Potatoes of the species "Perle von Samogy" were used for the experiment. The potatoes were planted in rows 60 cm apart, and the tubers were 30 cm apart. Plot rate: 2.5 mX8 m = 20 m2. The parcels were arranged as a random block. Each experiment was performed four times. Numerical values 32 listed in the table are average values of these four experiments. The soil was loamy with medium potassium content (19.5 mg K2O / 100 g). Winter wheat was used as a pre-culture and after harvesting it was plowed 18 cm deep (12 VIII). Fertilized was 1. IX.

In the spring of next year (1 st IV) the soil, pre-treated and pre-treated fertilized as described, treated with 4 g / ha of nitrogen fertilizer (34 wt% nitrogen content).

Potatoes were planted on May 5th. Four parcels on which the NsSCU-treated potatoes were planted were sprayed on preemergence with 5 kg / ha of Na 2 S 10 on May 10. Four additional parcels were sprayed with NazSQ-treated 1 kg / ha after NazSQ-treated potatoes.

The other four plots on which NazSOa-treated potatoes were also treated were pre-emergence 5 kg / ha and post-emergence 1 kg / ha Na 2 SO 4.

The parcels were observed and it was found that potatoes with damaged sprouts were substantially later (about 10 days) against normal time.

The large potato shrubs were counted on the 14th of June. The results are summarized in Table 23 below.

This example illustrates the effect of acidic sodium sulphate on alfalfa. In particular, the increase in growth, yield increase and substantial alignment values with untreated control experimental plants were investigated.

The experiments were carried out on plots of 0,25 ha and repeated 4 times. The soil was binding and clayey. Lucerne was a variety of "Nagyszénás".

Lucerne was planted 2 years before the experiments at 25 kg / ha and 2 cm deep. In the year in which the experiments took place, the Mayor was first harvested on 9 May (kneeling). Treatment with acidic sodium sulfate was carried out on May 25 when the second outlet reached a height of 10-15 cm; the plants were sprayed with a salt solution of 1 kg / ha, 2 kg / ha and 3 kg / ha in 400 l of water. The troop was then harvested (mowed) on June 14th.

The experimental results were evaluated as follows: In the period between treatment and harvest, differences between treated plots and untreated control plots were examined visually (differences in growth and phytotoxic effects). The height of the alfalfa plants was measured at 10 33 196329 36 locations along the diagonals of each individual. su. The results are presented in Table 26.

The weight of the alfalfa green mass was weighed on the day of harvest (June 14).

An optimum amount of salt used here is 1 kg / ha. c) From the point of view of improving the basic values, the most significant increase in carotin content in plants is the effect of sulphite sulphite by 18 to 25% compared to the control experiment. EXAMPLE 24 In this example, the effect of sodium sodium sulfate sulfate and potassium sulfite acid on salt cultures is investigated. In doing so, the vegetative soybean growth, yield and content (fat, protein) values are compared to the corresponding control values. The experiments were carried out with 0.1 hectares in size in four opaque operations. The soil was moderately viscous, its organic content was 2.6% (black humus). Pre-crop: winter wheat.

The sowing was carried out on 6 May with a sowing machine SPC-6 with a row spacing of 45 cm and a depth of 5 to 6 cm. The amount of seed was 109 kilograms / ha (32-36 beans / meter). Soybean species: Traverse.

Chemical weed control: 2.5 l / ha of Olitref, then 3 kg / ha of Malo-ran.

The plots were treated on May 12 with the salt of the invention using 300 l / ha of water (sprayer: Haflinger, Tel-Jet spray head 11.006, 200 kPa pressure). The use of the salt of the invention was 10 kg / ha. The control plots were not treated with salt. In the course of the treatment (May 12), the seed began to grow, about 5-10 ° C of seed already germinated.

Evaluation: During the vegetation period, evaluable parameters (plant height, phytotoxicity) were visually detected at four time points (May 19, June 28, July 4, and August 31) and compared with the control.

The effect of the crop yield was measured by weighing (September 28). Samples were taken from each plot at a time, and soybean content was determined from these samples. The results are summarized in Table 27 below.

At the harvest, all treated plots showed up as better; in addition, the average yield on average was 18.79%.

Expressed in the weight of the harvested beans, it also means a yield of 328 kg / ha.

By examining the contents, it was found that the protein content of the beans was about 2% less than in the control samples, while the fat content was equally high. Although the relative amount of protein in the area is somewhat smaller, as a result of the crop treatment, yields of 100 kg / ha of extra protein are increased.

Also, with sulfur sulfonic acid treatment, no differences were observed between treated plots and control plots. At harvest, yields on individual treated plots were larger than on control plots. Moreover, the average yield was 14.04%, ie 245 kg / ha. When examining the contents, the protein content of plants treated with the composition of the invention was found to be 3.3% less, while the fat content was 5.71% higher. In addition, the protein yield was 70 kg / ha, based on the area sown. EXAMPLE 25 In this example, the stimulant effect of the salts of the invention promoting plant growth on the vegetative development of diabetes (variety: Poles Beta # 102) and plant yield was demonstrated.

Experiments were carried out outside on a plot of 20 m2 (2.5X8 m) at four times repetition. The soil was clayey with an average potassium content of 19.5 mg K2O / 100 g). Feed pellets were grown as a preculture, then the soil was fertilized (September 5) with chopped nitrous potassium (4:14:14) and 18 cm deep (September 16). The following spring (February 19), another 34 kg / ha of nitrogen fertilizer was spread, whereupon (5th April) the soil was pulled and smoothed. On April 12, the soil was treated with 0.5 kg / Lenacil 80 WP and 5.5 1 / ha Ro-Neet weed control. The weed cultivation agent was incorporated into the soil with a milling plow.

Sugar seed was stained with the plant growth promoting salts of the invention or pre-emergence or post-emergence spray treatment as shown in Table 28 below.

Pickling was performed in a 120 rpm drum rotating pickling machine for 20 minutes, four days prior to seeding.

The pre-emergence spraying was carried out on a sieve after sowing with a compressed air spray machine (with a Tee-Jet11002 spray head).

Postemergence spraying was performed on day 45 after sowing in the same manner as pree-spraying. 16 days after sowing, differences in plant germination were observed and noted. The rate of germination was evaluated numerically from 1 to 3; the results obtained were summarized in Table 29 below. Meaning of numerical values: 1 - insufficient germination, 2 - satisfactory germination, 3 - good, even germination. <0 196329

In addition, this yield is extraordinary in the case of postemergent application of sodium sulphate, where the yield of sugar (6.225 t / ha) was almost twice the yield of the control experiment (3.526 t / ha). Example 2 6 In this example, experiments are carried out on large lands of 20 m X 250 m = 5000 m2 (0.5 ha). Sandy clay soil, in which maize was also grown in the previous year,

The control plot (100 m X 250 m == 25,000 m 2 = 2.5 hectares) lying next to the experimental plots is treated at the same time as the last 3.6 kg / ha of Eradicane®. it was plowed 25 cm deep and then drifted through the gates. A soil sample was taken, then the plot was fertilized (still in the past) with fertilized NPK in an amount corresponding to 260 kg / ha of nitrogen, 98 kg / ha / P 2 O 5 and 275 kg / ha of K 2 O. At the end of March of the following year, the soil was smoothed and conserved by a combi (cultivator, soil-ben, clod crumb). On the day before sowing, a plot of 3.6 kg / ha of EradicaneR (commercial designation of a composition composed of S-ethyldipropylthiocarbamate as an active ingredient and N, N-dlylyldi-chloroacetamide as an antidote) was sprayed.

Then, maize is sown and then 5.5 kg / ha of salts are treated preemergence with the salts shown in Table 32.

This is all the more surprising since the soil had this composition in the autumn: 129 mg of N, 2.8 mg of P2O5 and 20 mgK2O / 100 g of soil, and the soil with high potassium content was still fertilized with the amount of fertilizer in question .

When comparing the result of this example with the result of Example 13, which was performed one year earlier and under completely different meteorological conditions, there is a remarkable large concordance that demonstrates the reproducibility of the agricultural process. Example 27 (use of film as carrier) a) blank for 80 g of polyvinyl alcohol (viscosity of 4% aqueous solution at 20 ° C 0.4 Pa.s, degree of hydrolysis 89% v / v), trade name Rhodoviol 4/125 P) was added at 20 µl / 4 +9.4 III / 5 +10.6 degrees Celsius with shaking and mixing to 615 guards. When everything has gone into solution, 20 g of polyvinyl alcohol (viscosity 4% of the solution at 20 ° C, 3 s.sup.3, degree of hydrolysis of 98 vol.% (98% ml), trade name Rhodoviol 30/20 m) and 20 g of glycerin are added. The mixture is stirred or shaken until a homogeneous solution is formed. To remove buffers, the solution is allowed to stand for 24 hours and then with a spatula on a glass plate at a thickness of 0.5 mm, which is dried at room temperature. The resulting film can be easily removed from the glass plate.
