Description

The present invention relates to spraying for the treatment and / or prevention of plant diseases or for the control of plant growth, as well as their preparation and use.

Certain phytoparasitic insects live in symbiosis with fungi parasitizing on tissues, such as Enarmonia formoson and Cytospora cincta, or a clearing with fungi Croptosporioptis malicortici3 or Sphacropsis malorum, Other examples are:

- bark beetles (Scolitídese) and the fungus Pazidlola discolor,

- Hulobuis abietis and various putrefaction fungi and Cytospora,

- Sunantsdon myossfomy and Sphasropsis malorum,

- Bark beetle (Scoytus) causing destruction of the white elm with the fungus Graphium ulmi.

When insects lay eggs, they can also transmit epores or live mycelia of parasitic fungi to plants by helping their feet or excrement. Some parasitic fungi start their vital functions in places bitten by insects in the bast layer.

In the case of shrubby vegetation, the pathogenic fungus on the plant penetrates into the xylsma, the bast eventually into the woody part of the plant. Vital function of fungus develops Already at temperature ° C · Eggs of pathogenic insects deposited in corridors or on injured surface of the plant hatch in a few weeks. Worms penetrate the tissue and bark of the plant and live until they develop completely. The conditions for their life can be facilitated by the presence of parasitic fungi present at the time of egg laying, as the need for protein-for larvae will be covered by mature fungi. As a result, a malignant process occurs in the plant tissue. The formation of dead tissue is promoted by the larvae destroying the tissue important for fluid transport, thus disrupting the delivery of these fluids.

The insects live in the bark as a worm through the winter, and in spring or early summer, they experience metaraorphase at the last larval stage of the insect - the nymph. - The most exaggerated part of the nymph is expelled from the loose tissue and the imago appears. After fertilization, the imago returns to the same damaged part of the plant or to another freshly injured surface to lay new eggs, re-introducing spores and the mycelium of the aymbion, parasitic fungi and circulation continues.

Plant damage can be caused by different effects such as frost damage, bark wasting by the sun, snow breaks, ice, cultivation tools, vibrators, etc., open wounds, game bite, damage by insects living in plant tissue or open wounds caused by pruning . Malignant surface damage caused by fungi should also be considered. These openings provide an easy ceat for insects and parasitic fungi to penetrate into plants and thus set in motion the circulation described above.

In certain strains, such as Synanthedon tpuliformis, infection may be established if the imago does not fly immediately upon ingestion of the nyraf 'sheath, als-copulate in a few hours and immediately lays eggs, usually in the region of the escape slit. The worms begin to loosen the slits and penetrate inside the trunk or stem, destroying an ever larger area. Therefore, the lifetime of the imaga on the surface is very short and in vivo protection is difficult to apply. In the case of the plants mentioned above, the only way of protection is to remove and burn the strains or stems.

In the case of white elm, the bark beetle constantly moves inside the hadrom. Due to the rapid growth of Graphium ulmi, the blood vessels are blocked, resulting in partial or complete exhaustion of the tree.

The damage described above caused by the fungus and insect summation can be observed in potato, oilseed crops such as sunflowers, cereals and vines. For example, grass fell and gangrene occurs in cereal crops together with the damage caused by the whitening beetle.

A large number of insecticides and fungicides having a wide spectrum of efficacy have been used against parasitic fungi and insects living with them in symbiosis.

CS 273178 82

However, the known non-systemic insecticides have only surface activity, i.e. their effect is limited solely to the control of an image or butterfly not in contact with the plant. The effect on parasitic fungi in symbiosis with the image is of the same type.

Despite the widespread use of insecticides and fungicides, the spread of many plant diseases cannot be controlled. For example, insects that destroy the bark and bark, spread across a moderate range and cause substantial economic damage in the American and European countries, which, for example, lead to the destruction of the original white elm stands and the like.

The present invention allows for the manufacture of a plant treatment composition. At least one substance used for treating plants (hereinafter referred to as the basic active ingredient) with an alkyl methacrylate, preferably methyl methacrylate, is contacted by energy transfer in the presence of a crosslinking agent (inhibitor).

The energy transfer can be achieved, for example, by heat, ultraviolet or laser radiation, preferably with stirring,

Since the energy transfer is effected by the action of heat, the basic active ingredient, the alkyl methacrylate and the inhibitor are mixed and heated up to a temperature of 100 to 130 [deg.] C. The treatment is preferably carried out for 0.5 to 3 hours.

According to another embodiment of the invention, the mixture of the alkyl methacrylate, the basic active ingredient and the inhibitor is treated with ultraviolet radiation for 5 to 60 minutes at a temperature of 10 to 20 ° C, preferably with cooling. For this purpose, the quartz probe is equipped with a condenser and a quartz flask operating in the range of 300 to 500 nm is placed in the reactor. In this case, the stirring is performed with an inert gas, preferably nitrogen or carbon dioxide. When working without cooling, the reaction temperature rises to about 80 ° C.

In another embodiment of the invention, the alkyl methacrylate, the basic active ingredient and the inhibitor are treated by laser radiation. For example, the photochemical reactor is operated with vigorous cooling with water and nitrogen stirring, using 488 nm argon ions at 1 W reactor power for 2 to 3 hours. Using a 4 W apparatus (6 laser lines entering the reaction space together), the reaction time is reduced to 30 to 40 minutes. This embodiment of the reaction eliminates the need for thermal energy and the reaction can be safely controlled.

Oako surfactant can be used propylan glycol, polyethylene glycol or glycetate. The use of a surfactant in an amount of 0.001 to 0.01 wt. is sufficient.

CS 273178, .B2

By mixing the above stream with carriers and diluents 8Θ, a composition ready for use is obtained. For this purpose, water can be used in the form of 0.2 to 10% by weight. emulsion,

Another aspect of the present invention is the use and method of applying the above-described compositions to diseased trees that exhibit a therapeutic effect, or to healthy trees, as a preventive agent.

For example, the composition may be formulated as a paste, a viscous solution or an aqueous solution (such as a spray).

If labeling is required, additives, pigments or materials containing pigments may also be added to the composition. Such additives are, for example, indatane derivatives which are then degraded when exposed to ultraviolet radiation.

Biological Effect of the Compositions of the Invention! has been tested and tested against plant diseases caused by different insects and fungi. Such diseases include, for example.

- carcinomas caused by Enarmonia formoson and Cytospora cincta on apricots with peach trees,

- carcinomas caused by bark beetle (Schytus) and Phaeciodella discolor on pear and apple trees,

- black carcinomas caused by Synanthedon mypaefonis and Sphaeropsia malorum in Apple trees, and pear trees,

carcinomas caused by Nectrie galligensa on pear and apple and the like.

The compositions according to the invention are particularly effective against Entypa grapevine fungi and various fungi of the genus Cytosporina, which have an important effect especially during the cultivation of cordons.

The use of the compositions according to the invention on grapevines can be carried out, for example, as follows:

The basic requirement of protection is to exclude infection centers. Truncated shoots and rotting strains should be removed and burned from the vineyard. Cordon nourishing strains have at least a partially rot-rotated surface that allows the fungus to grow. Adult fungi form cellulase sporangia, which grow in volume due to rain and expel joints. These joints are transmitted by wind, insects and rain, Oak mentioned above, this is possible in spring rains, the joints are punched out on the wounds caused by pruning the cordodes of the vine, where the fungus grows under ideal conditions. Protection should be achieved on this basis.

1. The strain should be sprayed with an aqueous emulsion of the composition according to the invention (spraying containing silicone compounds is preferred). As a result, the active ingredient kills mycelia and fungal joints, while the silicone compounds cause the strain to be hydrophilic and prevent water from penetrating so they cannot increase volume and expel disputes.

2. After pruning, the cordon should be sprayed with a composition according to the invention comprising a fungicide and an insecticide which is effective against Enarmonia formoeon, thus stopping the gutting of the stumps,

In the case of infected cordons, a spray spray or wash with the aqueous form of the composition of the invention should be used, preferably at 20% dilution. When the detergent is used after pruning the gut, secondary fungal infection is eliminated,

The aqueous composition of the present invention as a spray for infections at the wound site is recommended for the treatment of wounds caused during winter or early spring. Preferably, the spraying is carried out at an average temperature of only + 5 ° C. It has been tested that the wounds heal well and prevent disease.

The composition according to the invention can be applied to the injured area by any spraying device. The composition may also comprise a curing agent and an insecticide to prolong the effect.

Spraying with a 5% solution of the composition according to the invention provides effective protection. In the case of an aqueous solution, 500 to 800 liters per hectare are effective. Application can be accomplished by means of a sprayer provided with a spray gun or other conventional means.

During treatment, the spray should be directed to the cut surface.

In certain cases (for example, in the case of a strong infection of Entypa on grapevine), the active ingredient may be sprayed as such, i.e. without dilution with water.

The other possibility of using the means is pickling. For this purpose, the active ingredient should be used in a 5 to 10% aqueous solution of casein, as a preferred adjuvant, for cereals, maize and onions. The use of casein is not absolutely necessary.

In the case of tuberous crops, the pickling time is 1 to 10 minutes. The grain can be treated in conventional pickling facilities. Emulsions with higher concentrations (e.g. 40 to 60% by weight) can also be used for this purpose. The addition of an indicator (red) to the pickling emulsion is preferred.

The most effective protection is achieved by so-called direct spraying '. Both self-propelled sprayers 8 and towed sprayers can be used for this purpose.

In the rest period after regeneration, the composition of the invention should be diluted at + 5 ° C to 5% and sprayed with a gun onto the cut or cut wound surface. This treatment method requires spraying 400 to 600 liters of solution per hectare.

An aqueous solution of the composition of the invention may be used on an infected apple tree at a dilution of 15% or in the case of a more severe infection to 20%. Application may be by any suitable sprayer using 500 to 800 ml of an aqueous solution.

□ regular spraying may be omitted if the stem or flower-bearing part of the trees or the cordon part of the vine is sprayed in autumn or early winter (November and December).

It has been tested that the composition of the invention penetrates to a depth of 20-30 mm in living tissue and kills insect bark and bull insect nymphs and larvae, as well as spores and mycelia of parasitic fungi without causing any damage to the plant.

For comparison, the biological effects of the individual components of the compositions of the invention were determined. It was found that no combination with the base active ingredient - hydroquinone, methyl methacrylate - hydrquinone and the base active ingredient - methyl methacrylate had an effect comparable to that of the composition of the invention.

When the hydroquinone is omitted, the parent drug is kept suspended in the liquid monomer by continuous stirring to avoid sedimentation and discoloration. The heat treatment of the base active ingredient hydroquinone system should only be carried out in the presence of a solvent. For example, heat treatment of Benomyl and hydroquinone in the presence of toluene provides a mixture whose biological activity does not exceed that of the parent drug.

The process of the invention is illustrated by the following examples.

Example 1 part by wt. Chinolphos, 1 part wt. Deltamethrin and then 1 part by weight of methyl methacrylate; hydroquinone and 3 parts by weight. The Benomyl was charged to a stirrer reactor, heated to 110 and then cooled. The emulsifier L-tazol AT 25 (tallow esterified with an aliphatic alcohol, 25 EtO) was then added followed by a wetting agent containing 0.01% fluorocarboxylic acid (Likovet, Hoechst) and the mixture was stirred. This gives 9 kg of a liquid dark brown product which can be filtered as necessary.

The solution thus sprayed is sprayed onto fruit trees, especially apple trees, after dilution to 0.5 to 1% with water. The composition can be effectively used against vegetative or parasitic fungal diseases and insects. The product suppresses grass powdery mildew, peronoepora, fungi attacking stumps, neeytka, lice and mites.

A sample of the solution is used without dilution for cordon cultivation of the vine that sprouts or falls, using a special sprayer or brush. It has been found that after treatment with cordons infected with Eatypa and Cytospora cincta, they show intense budding and leaf development as a sign of pest destruction. If a tissue sample taken from the Eutypa killed vine cordon is placed in the growth medium, growth of Eutypa and Cytospora cinsta cannot be observed after 7-8 days. The result of treatment are that the larvae β eggs of the clearing.

the marbled carpet caterpillars and mites placed under the bark are killed. Tissues that remain intact prior to treatment intensify around the summer solstice and the cordonova leaves are also normal.

Example 2

The procedure of Example 18 was followed except that 2 parts of methyl methacrylate, 2 parts of Benomyl, 2 parts of hydroquinone and 0.5 parts of Chinalphoau were heated to 110 ° C with stirring. 2 to 3 parts of 0.5% Sudan red stained polyvinyl butyrate were added to the mixture.

After cooling, the surfactant of Example 1 is added and the mixture is diluted with 5% turpentine based on the total amount of solution. The viscosity is adjusted to 60-70 cP by addition of methyl methacrylate.

The solution thus obtained is applied to the surface of apple trees infected with Cytospora cincta and Eutypa or Sphaeropais malorum, or to the bark of stone fruit trees, using a separate sprayer. The wound surface is opened 20 minutes after treatment and dead larvae and nymphs are found.

A sample removed from tissue damaged by parasitic fungi is placed on the surface of the medium, incubated and observed on day 8. No fungal growth was observed on the medium. The cocoons of hairy aphids, worms and tinker are dead and eggs dry. They are resistant to normal plant protection products due to a layer of wax on their surface that prevents contact with eggs. It has also been found that the adhesive layer connecting the fibrin fibers that form the cocoon dissolves and thus destroys the structure.

Example 3

The product of Example 2 is supplemented with 4% by weight of quinine hydrochloride or quining sulfate. The solution thus obtained aa is sprayed on the bark of young trees at the end of October or early November. It was found that the bark of nani during winter damaged animals, especially rabbits. When applied to grapevine cordons, in addition to the effects of Example 1, frost damage is also prevented.

Example 4 parts of Benomyl, 1 part of Chinalphoeu, 1 part of Deltamethrin, 1.5 parts of hydroquinone and 3 parts of methyl methacrylate are stirred in the reactor at 105 ° C for one hour.

The mixture was allowed to cool to room temperature and Lutazol AT 25 emulsifier and 0.01% Likovet wetting agent were added to the mixture. If desired, the dark brown solution ea is filtered.

In the above system, ss dissolved 1 to 2% quinine hydrochloride.

The 0.5 to 1% water-diluted solution described above is applied to maize, young pine and vine eyes. No damage to the game is observed. The treatment also causes destruction of the eggs under the cortex.

Example 5

A mixture of 75 g of Triadimsphone, 100 g of Folpat, 100 g of hydroquinone, 3000 g of methyl acrylate, 80 g of Chloropropylate, 100 g of Chinalphoau and 100 g of Deltametrin ee is heated at 110 ° C for 30 minutes. After cooling, 1-5% of Lutazol emulsifier or lauryl sulfate and 0.01% of Likovet are added. 0.4% of the trace element composition, for example Wuxal, is added to the brownish solution as a 1% solution.

A 0.4 to 0.5% aqueous solution is prepared and used on the surface of an infected grapevine by conventional methods. After a few days localized fallen grass and peronospora on the surface of the leaves. In the absence of infection at the time of treatment, overall protection is achieved, the same effect is observed against gray weed and harmful insects.

Example 6

The active compound of Example 5 is prepared and, after cooling, 20 mg of vitamin B ₁ and 1 mg of .alpha.-naphthylacetic acid are added thereto. Before dilution with water, 0.01% of a composition containing trace elements (for example Mikomit) is added.

After spraying the agent on the cordon leaf system, the leaves grain the color to dark green · Leaf analysis shows that due to the growth of trace elements, especially iron and manganese, ee increases the assimilation activity as microelements penetrate deeper tissue layers. An increase in the iron content is also observed.

It is well known that 80 to 90% of the grapevine has mechanically or biologically damaged tissue. Due to the effect of the cellulose-degrading enzymes present in the tissue that are activated when the tissue is damaged, the viscosity of the fluids increases and the fluids are no longer able to hold the metal ions in solution. Thus, the ions required for vegetation cannot replenish when sucked from the soil. The treatment of this example allows for the suction of fluids and ions into deeper tissue layers.

Example 7

The preparation and the active ingredient components are identical to those in Example 6. After cooling, when emulsifier and a precipitating agent are added, 5 mg of gibberellic acid, 5 mg of β-indolylbutyric acid and 10 mg of potassium bicarbonate are also admixed in the solution. The composition is used as a 0.5% aqueous solution, after mixing β 0.4% of the trace element mixture.

When sprayed 10 to 14 days before flowering, the number of flowers increases by 30 to 40%.

Treatment with the same solution after flowering increases the number of grapes by 70 to 80%,

The same treatment 14 days after flowering results in:

- the ripening period will be reduced by 20 days,

- the sugar content increases by 3 to 4%,

- the number of grains decreases by 25%.

The use of the composition will provide permanent protection against peronospora, powdery mildew, gray mold, as well as marble moth caterpillars and mites.

Example 8

100 parts of methyl methacrylate, 20 parts of hydroquinone, 1 part of chinalphos, 1 part of Phormothion, 1 part of Oeltamatrin and 1 part of chloropropylate are heated at 105 ° C for one hour and 40 parts of ground naphthosene slate (particle size 10 µm) are added, then is cooled and mixed with 5 to 5% emulsifier (24%) and 0.01% wetting agent (Likovet).

Dilute the solution to a concentration of 1% and spray at least three times on the apple tree with the usual equipment between July and August.

It has been found that the calcium and magnesium content of the apple increases, the structure of the fruit is stronger and the shelf life may be increased by 3-4 months. The fruit does not contain insects or fungi.

Example 9 parts of methyl methacrylate, 2 parts of Triadimephon. 2 parts of hydroquinone, 4 parts of Permetrin, 1 part of Tetramethrin, 5 parts of Benomyl, 1 part of Chloropropylate and 10 parts of Chxnalphos are heated to 110 ° C and then cooled. To this is added 5% of the known emulsifier (Lutazel AT 25 or allurin sulfate) and 0.01% of Likovet.

The potato leaves are sprayed with a 1 to 1.5% water-diluted mixture of 200 liters per hectare with a sprayer. The treatment suppressed the infection caused by Phytospora, which is surprising because Benomyl alone does not show the same effect. Potato leaves change color to dark green.

Example 10

The Baysilon PL silicone emulsifier was added to the active compound of Example 9 and the mixture was diluted with water to a 1 and 2% solution before spraying. Oiky silicone film formed on the surface of potato leaves Colorado potato beetle, which often arrives on potato plants and before destroying holes holes on the surface of the leaf, can not deposit viruses on the leaf.

Example 11: Comparative experiment β.

The mixture of Example 1 g is prepared except that the heat transfer is omitted.

A 0.5 to 1% aqueous solution is prepared from a mixture of emulsifier and wetting agent.

The composition thus obtained is sprayed on fruit trees against vegetative fungi caused by diseases and harmful insects. Growth of powdery mildew, peronogpor and scobbing can be observed on the foliage surface. Upon transfer of the scrapers from the trunk and branches to the growth medium and treatment, as in the previous examples, the growth of parasitic fungi can be observed after 3 days.

Spraying kills only 20% of insects and 5% of mites. Suppression of powdery mildew is observed after repeated spraying after two weeks with the same formulation, but the growth of peronospora and parasitic fungi remains unchanged. 10-15% of the insects die.

Example 12: Comparative experiment

The procedure of Example 4 is repeated except that the transfer of energy is not ensured.

A 0.4-0.5% solution is prepared from the mixture and sprayed onto the surface of the vine leaves. The growth of powdery mildew is suppressed, but remains ineffective against peranospora and gray mold damage. Spraying ae paralyzes 30 to 40 mites, but you ee recover in hours. 20% destruction of the marbled carpet caterpillar is observed.

Example 13j Comparative experiment

The procedure of Example 1 is repeated, but without heating the solution. The material is sprayed onto the cordon surfaces prior to setting the buds and samples are taken from dead tissue infected with Eutypa and placed on growth medium. After 48 hours, intense growth of Eutypa and Cytospora cynota was observed. Also, formation of misshapen leaves severely suffering from a lack of chlorophyll is observed, which does not improve. No effect on Eutypa can be determined. Example 14: Pickling

To the mixture of Example 5 was added 3% casein or ethyl acetate. The material is diluted to 15% and evenly applied to the grain surface of wheat or maize in the pickling apparatus. One or two days after sowing wheat seeds germinate and in 2 or 3 days the loops will grow above the soil. Germination of maize begins at a soil temperature of 5 to 6 ° C and the loops grow over the soil within a few days.

When pickling is carried out with the same mixture but which has been prepared while avoiding heat transfer, germination and emergence are delayed by at least 8 to 10 days.

Example 15

The process of Example 14 is repeated, but adding 0/2% lindane and omitting the use of casein and acetate. Seeds and sealed solution in a fluidizing mixer.

Treated grain grain germinate! z-a 1 to 2 days and emerge after 3 to 4 days. Plants are harvested after one month and the richness of the roots is tested, given the plants that have come from seeds stained by the usual methods.

Example 16

A mixture of 15 parts of methyl methacrylate, 2 parts of hydroquinone, 5 parts of quinine hydrochloride, part of Chinalphoeu, 1 part of Daltamatrin and 2 parts of Benomyl is heated at 110 ° C for one hour and then stirred in a homogeneous mixture. A 2% aqueous solution of the mixture is sprayed onto pine, aspen and walnut. It is observed that the deer does not bite the crown of pine trees, the fungi occurring on the infected aspen and nut surface are localized and, depending on the amount of spray used, the insects are killed, in some cases up to a depth of 2-3 mm.

Example 17

A mixture of 20 parts of methyl methacrylate, 2 parts of hydroquinone, 5 parts of Benomyl, 1 part of Captan, 1 part of Oeltamethrin and 0.2 parts of β-indolylbutyric acid is heated to 105 ° C for 1 hour and mixed homogeneously with known emulsifiers and wetting agents.

The mixture was sprayed at a dilution of 0.3 to 2% on so many alfalfa and sunflowers. The blend provides protection against mildew leaf mildew on so many alfalfa and sunflower lodging. Regular spraying can eliminate sunflower scalding. · The aphid wounds are removed without infection and the aphids themselves die.

Example 18

A mixture of 18 parts of methyl methacrylate, 6 parts of Benomyl, 2 parts of Thiadimephon, 2 parts of hydroquinone, 1 part of C-naphthylacetic acid and 0.5 parts of indolylbutyric acid was heated at 110 ° C for 1 hour, then cooled and mixed with an emulsifier and a wetting agent to form a homogeneous material which is diluted to a pH. concentration 0.4 to 1% ·

At the end of September or October, when sprayed simultaneously with foliar fertilization on wheat, winter barley and common rye, the weight of the roots will increase by at least 50% compared to the control. The number of leaves increases, as does the chlorophil content. Basic active materials are used as a control.

Example 19

15 parts of methyl methacrylate, 3 parts of Benomyl, 1 part of Captan, 1 part of Folpet, 2 parts of Methidathion and 1 part of Deltamethrin are introduced into the reactor equipped with an agitator. Stirring is performed with nitrogen gas. A double wall quartz probe surrounding a 340 to 390 mm quartz flask is placed in the reactor. The quartz flask is connected to a solution stirred with a stream of nitrogen and cooled for 30 minutes.

The composition can be used for pickling corn, wheat and so many alfalfa grains. After soaking, the grains can be simply dried and the usual casein coating omitted.

The starch in the grains is bound to the spray of the hydroxy groups and thus achieves protection against soil infections.

Example 20
