Description

· », · \ - Plant growth control composition -

The invention relates to a plant; growth control and crop maturation acceleration composition, containing 0.2-95% by weight of 3-isononyloxypropylammonium methylphosphonate and a solid or liquid filler or carrier and optionally | 5 other additives, preferably a surfactant and / or a bightening enhancer in an amount which : makes up to 100% by weight.

The preparation of 3-isononyloxypropylammonium methylphosphonate as well as its use as active ingredients of a fungicidal composition should be described in Hungarian patent 184319; regulating plant growth however, the effect of the aforementioned active compound is effected! ! not described in this patent.

It has now been found that 3-isononyloxypropylamino! 15methylmethylphosphonate, when used in an appropriate dose, can be used to control root development, growth, leaf surface development as well as crop binding, flower binding and crop maturation of plants grown in the field, for example wheat, corn, 20 sugar beet, sunflower as well as horticultural plants, for example pepper, tomato, radish, potato, furthermore from fruit trees, for example apple and currant plants, such as currants] and wine. \ i |

For controlling plant growth or for accelerating crop maturation, the composition of the invention may be used at a concentration of 1-2000 parts per million of the active ingredient. The used i | ! dose depends on the plant to be treated, on the purpose of the treatment, the phenological phase of the plant and on the form of the composition. j § 5 0 2 5 8 2 i: I Consequently, the invention also relates to

i to a treatment process for controlling plant growth i

ί | ! and to promote flower and crop binding and j! 5 crop maturation in which the seeds, plant principles and flowers are treated with an amount of 1-2000 parts per million j! of the active ingredient or soil of the plants; i 2! j treats with an amount of 0.001-5.0 g / m of the action ve ingredient for sowing, or by an amount of! | 1-2000 parts per million of the active ingredient by sprinkling after planting or after deposition using a composition containing 3-isononyloxypropylammonium methylphosphonate as active ingredient in an amount of 0.2-95 wt% and a solid or liquid filler as a carrier and optionally other additives, preferably a surfactant and / or an adhesion promoter in an amount which complements up to 100% by weight.

For practical use, the active ingredient of the invention is formulated into a composition using solid or liquid carriers and optionally other additives, suitable surfactants and adhesion promoters.

Suitable carriers include organic or mineral, natural or synthetic materials, which | 25 to promote adsorption or absorption of the active ingredient (for example, water, methanol, glycerol, waxes, resins, talc, etc.). j

Suitable surfactants include ionic and / or nonionic 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 carboxymethyl cellulose. j

The compositions of the invention may be formulated as water-soluble concentrates (WSC), j-3 wettable powders (WP), dusting powders, emulsifiable concentrates (EC) or granules (G).

Further details of the invention are illustrated by the following nonlimiting examples, in which BF-51 means 3-isononyloxypropylammonium methylphosphonate. j

It will be apparent from the results that the development of the plants is greatly enhanced by all three active compounds compared to the untreated blanks.

However, the plant height / green weight ratio indicates a more preferred effect of BF-51 compared to that of the reference substances. Thus, it has been found that the habit of the corn is not adversely affected by BF-51, while deformed, lanky plants with an unfavorable habit develop under the effect of gibberellic acid. The results of the chlorophile assays have shown that the effect of BF-51 is most favorable on the amount of chloroform formed both in one gram of the green plant and in the whole green plant, respectively.

Example 16

The root zone of tomato seedlings is sprinkled with 0.1 liters of a BF-51 90 WSC solution at 250 parts per million concentration as calculated for each 20, individually. The development is evaluated after 6 weeks.

The results are shown in Table K.

It will be apparent from the results of the measurements that the ripening processes of the apple treated with BF-51 have been delayed, allowing a later picked apple to be stored in the optimal state of ripeness and storage, which is a prerequisite is for good storage (keeping quality).

The data in Table M shows that the apple! treated with BF-51 can be stored advantageously despite late picking and late storage.
