Description

Accordingly, the invention relates to a method for regulating plant growth, preferably to promote flower bonding, harvesting, harvesting. the formation, root formation and development of the plant parts containing the nutrient material, the method 1 being characterized by treating the seeds, the vegetative reproductive structures and the flowers with a composition containing 0.2-95% by weight of 3-isononyloxypropylammonium methylphosphonate as active constituent and solid or liquid filler or carrier and optionally other additives, preferably a surfactant and / or adhesion promoter in an amount constituting the remainder up to 100% by weight, in an amount of 1-2000 ppm of the active ingredient or plant soil with an amount of 0.001-5.0 g / m2 of the active ingredient before sowing or with an amount of 1-2000 ppm of the active ingredient by spraying after planting or planting.

Prior to practical use, the active ingredient is formulated into a composition using solid or liquid carriers and, if appropriate, other additives, suitably surfactants and adhesion promoters.

Suitable carriers include organic or inorganic, natural or synthetic substances, which promote the adsorption or absorption of the active ingredient (for example, water, methanol, glycerol, waxes, resins, talc, etc.).

Suitable surfactants include ionic and / or non-ionic emulsifying and dispersing or wetting agents, preferably alkylaryl polyglycol ethers and fatty acid polyglycol esters; Suitable adhesion promoters * are, for example, polyvinylpyrrolidone, polyethylene glycol and carboxymethylcellulose.

The composition used can be prepared as water-soluble concentrates (WSC), wettable powders (WP), powders, emulsifiable concentrates (EC) or granules (G).

The invention is further illustrated by the following working examples, in which BF-51 relates to 3-isononyloxypropylammonium methylphosphonate.

Example 1 A solution is prepared from the following components:% BF-51 Emulsogen NO90 (alkylaryl polyglycol ether) 0.5 Methanol 94.5 Example 2 A solution is prepared from the following components:% BF-51 2 Arkopal.N08O (nonylphenol polyglycol ether) 0, 51 Glycerol 97.85 Example 3 A solution is prepared from the following components:% BF-51 90 Arkopal N150 (nonylphenol polyglycol ether) Dimethyl sulfoxide 5 Example 4 A mixture containing 10 g of BF-51 and 100 ml of methanol is homogenized with 90 g of talc. After evaporation of the methanol under reduced pressure, a powder composition with an adhesion of o, os-o, o1 g / cm2 is obtained. 4654 10 15 20 25 30 35 4112 Example 5 A mixture containing 10 g of BF-51, 10% polyethylene glycol, 0.1 g of emulsifier NO 90 (alkylaryl polyglycol ether) and 100 ml of methanol is homogenized with 79.9 g of talc. After V: evaporation of the methanol under reduced pressure, a wettable powder containing 10% of active ingredient is obtained, the adhesion of which amounts to 0.07-0.01 g / cm 2.

Example 6 A mixture containing 10 g of BF-51, 5 g of polyvinylpyrrolidone, 0.2 g of Arkopal NO80 (nonylphenol polyglycol ether) and 100 g of methanol is homogenized with 84.8 g of talc. After evaporation of the methanol under reduced pressure, a wettable powder containing 10% of active ingredient is obtained, the adhesion of which is 1-.111 o, o1-o, oø2 g / cm 2.

Example 7 100 g of mother-of-pearl are stirred vigorously with 100 g of BF-51 and after allowing the mixture to stand for 2-3 hours it is filtered and the product is dried at 40 ° C for 1-2 hours.

Example 8 100 g of mother-of-pearl, 100 g of BF-51 and 25 g of Sipemat 50 (a synthetic silicate) are mixed thoroughly and then the method of Example 7 is followed.

Example 9 'Potato sprouts, which had been taken from a potato tuber' using a plug drill, were dipped in solutions containing different concentrations of the test substances for 10 minutes and then placed in culture flasks. 464 442 3-Indolylacetic acid (IAA) and gibberellic acid (GA) were used as reference substances.

This is especially important for areas where an early planting of the potatoes can be spoiled by an unfavorably cold spring weather.

Example 13 Ten vine shoots with 5 buds each for each treatment were soaked in solutions containing 10, 100 and 500 ppm BF-51 90 WSC, respectively, for 24 hours and then the shoots were grown under greenhouse conditions in plastic containers in a humus and sandy soil.

After 3 months of cultivation, the length of the shoots that had developed on the vines was determined for each plant, and after the shoots and roots had been cut away from the vine stalks, the weight of these was determined. Mean values were determined for each treatment and the development of the shoots 464 442 and the root was compared with the control sample. The results are summarized in Table V.

The root development of the cuttings was promoted by BF-51 90 WSC in the concentration of 10, 100 and 500 ppm.

Example 14 Perlites, which had been soaked with the same amount of Hvagland nutrient solution, were placed in 4 plastic culture flasks, each with an opening surface area of 214 cm 2. Different doses of BF-51 50 G, which had been prepared according to Example 7, were applied evenly over the perlite surface, after which 10 grains of wheat were sown in each bottle.

After incipient shoot formation, the rate of shoot formation at each treatment was evaluated until shoot formation relative to the untreated control reached 90% (Table VI). Furthermore, the percentage germination, shoot length, fresh weight and root weight in the 4-leaf stage were determined in relation to the control plants (Table VII).

Example 15 Maize was sown in culture flasks (5 plants / bottle) and sprayed after emergence with a solution containing BF-51 or gibberellic acid and 3-indolylacetic acid, respectively, at the concentration of 250 and 500 ppm, respectively. In the 4-leaf stage of the untreated control plants, the length, fresh weight and root weight of the plants were determined (Table VIII) as well as the chlorophyll content, which was determined at the tip of the second leaf of each plant (Table IX). 12 464 442 f: .uounm fi m mm fifi mnmm uwxuæë mmwmHx0w> u5 mnæwc flfifi wuwnn fl m> m: mxHw> u fl Hoøcb ¥ w ~ ._ «m.> W mm., °« .m ~ P @_.

However, the plant height / fresh weight ratio is related to; a more preferred effect of BF-51 compared to that of the reference substances. Thus, it appears that the habitus of the maize was not adversely affected by BF-51, while disproportionately viable plants with an unfavorable habitus were developed under the influence of gibberellic acid. It appears from the results of the chlorophyll determinations that the effect of BF-51 was the most favorable both in terms of the amount of chlorophyll formed in one gram of the green plant as well as in the whole green plant.

Example 16 The root zone of tomato seedlings was sprayed with 0.1 liter of a BF-51 90 WSC solution at a concentration of 250 ppm, calculated for each individual. The development was evaluated after 6 weeks. The results are summarized in Table X.

The ripening process of the treated apple was then studied by respiration measurements (Table XI) and by examining the hardness of the pulp (Table XII). At the same time, the durability of the treated apple was also studied (Table XIII).

The data in Table XII show that an apple treated with BF-51 can be stored with advantage despite late harvest and late storage.
