Plant growth regulating composition

The invention relates to a composition for regulating the growth of plants and accelerating the ripening of the crop, containing 0.2 to 95% by weight of (3-isononyloxypropylammonium) methylphosphonate,

having H H

Formula: CH-10-O-O-NH4-CH2-Cl2-Cl-O-isononyl and solid or liquid fillers or carriers and optionally other additives, preferably surfactants. substance and / or adhesion promoter, a missing amount of 100% by weight.

The preparation of (3-isonyonyloxypropylammonium) methylphosphonate as well as its use as an active ingredient in a fungicidal composition is described in HU Patent Publication 184,319 (corresponding SE Publication No. 447533); however, this patent does not disclose anything about the plant growth regulating effect of the above-mentioned active ingredient. It has been found that methyl phosphonate (3-20 isononyloxypropylammonium) applied in suitable doses can be used in addition to field crops such as wheat, corn, sugar beet and sunflower, as well as horticultural crops such as peppers, tomatoes, radishes and potatoes. to regulate tree, and berry plants, such as grapes and vines, root development, growth and leaf surface growth as well as crop attachment, flower attachment, and crop ripening.

To control the growth of plants or to accelerate the maturation of the crop, the composition according to the invention can be used containing 1-2000 ppm of active ingredient. The dose to be used depends on the plant to be treated, the purpose of the treatment, the phenological stage of the plant and the form of the composition.

Accordingly, the invention also relates to a treatment method for controlling plant growth and promoting flower and crop attachment and crop ripening, which method comprises treating seeds, plant beds and flowers with a composition containing 1-2000 ppm of active ingredient or treating plant 2 before sowing in an amount of 0.001 to 5.0 g / m 3 of active substance or after implantation or bending by spraying with a composition containing 1 to 2,000 ppm of active substance and using a composition containing 0.2 to 95% by weight (3-isononyloxypropylammonium) as active ingredient methylphosphonate and a solid or liquid filler or carrier, and optionally other additives, preferably a surfactant and / or an adhesion promoter, in an amount of 100% by weight.

Prior to actual application, the active ingredient according to the invention is formulated using solid or liquid carriers and, if appropriate, other additives, preferably surfactants and adhesion promoters.

Suitable carriers are organic substances or mineral and natural substances or synthetic substances which promote the adsorption or absorption of the active substance (e.g. water, methanol, glycerol, waxes, resins, talc, etc.).

Suitable surfactants include ionic and / or nonionic emulsifying and dispersing or wetting agents, preferably alkylaryl polyglycol ethers and fatty acid polyglycol esters; suitable tackifiers include, for example, polyvinylpyrrolidone, polyethylene glycol and carboxymethylcellulose.

The compositions of the invention may be formulated as water-soluble concentrates (WSC), wettable powders (WP), dusts, emulsifiable concentrates (EC) or granules (G).

Other details of the invention are illustrated by the following non-limiting examples in which, in Examples-35, BF-51 represents (3-isononyloxypropylammonium) methylphosphonate.

Untreated control tubers were planted at the same time as the treated tubers or a week earlier. The yield was estimated. The results are summarized in Table IV.

Based on the results, it can be concluded that tubers treated with BF-51 can be planted one week later without causing a delay in the development of (later planted) plants. This is particularly important in areas where unfavorable cold spring weather may jeopardize early planting.

Example 13

Ten vine shoots, each with 5 buds, were soaked for 24 hours in each treatment in a solution containing 10, 25,100 or 500 ppm BF-51 90 WSC, and then shoots were grown under greenhouse conditions in plastic containers in humus and sand-containing growth medium.

After three months of cultivation, the length of shoots developed in the vine cuttings was determined for each plant and then the mass of shoots and roots after ir-cutting from the vine stem. The results were averaged for each treatment and the development of shoots and roots was compared to control plants. The results are summarized in Table V.

The development of root roots of cuttings was promoted by BF-51 90 WSC concentrations of 10, 100 and 500 ppm. Example 14

Perlites moistened with the same amount of Hvagland nutrient solution were placed in four plastic culture flasks, 2 each with an orifice area of 214 cm. Various doses of BF-51 50 G prepared according to Example 7 were evenly applied to the surface of the perlites 20, after which 10 wheat grains were sown in each flask.

After the onset of germination, the germination rate for each treatment was continuously monitored until the germination percentage of untreated control plants reached 90% (Table VI). In addition, the germination percentage, shoot length, green part mass and root mass with reference plants in the four-leaf stage were determined.

The results show that a) the germination rate of the plants accelerated as a result of the treatments and b) the height of the plants and the mass of the green part of the plants increased significantly compared to the control plants.

After emergence, maize (5 plants / bottle) sown in culture flasks was sprayed with a solution containing BF-51 or gibberellic acid or 3-indolylacetic acid at a concentration of either 250 ppm or 500 ppm each. With untreated control plants in the four-leaf stage, the length of the plants was measured by the mass of the green part and the mass of the root (Table VIII); the chlorophyll content of the second leaf tip of each plant was also determined (Table IX).

The results show that all three active substances significantly promoted plant development compared to untreated control plants.

However, the plant height / green part mass ratio 5 suggests that BF-51 has a more favorable effect than the reference substances. Thus, it appears that BF-51 does not adversely affect the natural growth pattern of maize, whereas, under the influence of gibberellic acid, plant-10 and. The results of the chlorophyll assays show that BF-51 had the most beneficial effect on the amount of chlorophyll formed both in 1 g of green plant and in the whole green plant.

Example 16

The root zone of tomato seedlings was sprayed with a solution containing 250 ppm of 15 BF-51 90 WSC at 0.1 l per individual. Development was assessed after 6 weeks. The results are summarized in Table X.

The measurement results show that the ripening processes of the apple treated with BF-51 are slowed down, which allows the later harvested apple to be stored in the most favorable state for ripeness and storage, which is a prerequisite for good storability (preservation of quality).

The results shown in Table XII show that apples treated with BF-51 can be stored with favorable results despite late harvesting and late storage.
