Plant growth regulating preparation and method for controlling plant growth.

This invention relates to a plant growth regulating and maturing accelerating composition containing as active ingredient 0.2 to 99.5 wt.% Ammonium phosphite according to formula 1, in which formula a C 1 -alkyl group, R 2 a (C 1 -alkoxy) - 5 represents C 1 -alkyl or a C 2-12 alkyl group and hydrogen or a C 1-20 alkyl group. The rest of the composition consists of solid or liquid filler or carrier and any other additives, preferably surfactants and / or adhesion promoters.

The preparation of the active substances of formula 1 and their use as fungicides is described in Hungarian patent 184,319, but the plant growth regulating effect thereof is not mentioned in that patent.

It has been found that when used in appropriate doses the above compounds of general formula 1 can be used to control root development, growth, leaf surface formation and fruit set, bud setting and harvest maturation. standing crops such as wheat, corn, sugar beets, sunflowers and garden crops such as peppers, tomatoes, radishes and potatoes, and further from fruit trees such as apples and currant plants such as grapes and currants.

For controlling plant growth or for accelerating fruit set, the composition according to the invention can be used with a concentration of active ingredient between 1 and 2000 ppm. The dose depends on the plant to be treated, the purpose of the treatment, the phase of the plant and the form of the preparation.

The invention therefore relates to a method for controlling plant growth and for promoting budding, fruiting and harvest ripening, whereby the seeds, starting plants and flowers are treated with 1 to 2000 ppm of active ingredient, or the soil for the plants before sowing with 0.001 to 5.0 g / m2 of active substance or after planting by sprinkling with 1 to 2000 ppm of active substance, the preparation being 0.2 to 99.5% by weight of compound according to formula 1, where R5, R5 and R5 have the definitions given above and the remainder consists of solid or liquid carrier or filler and any other additives, preferably a surfactant and / or adhesion promoting substance .

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

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

Suitable surfactants include the ionic and / or nonionic emulsifiers, dispersants and wetting agents, preferably alkylaryl polyglycol ethers and fatty acid polyglycol esters; suitable adhesion promoters are polyvinylpyrrolidone, polyethylene glycol and carboxymethyl cellulose.

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

Further details according to the invention are illustrated by the following, non-limiting examples, in which the active substances are indicated as follows: • 3-butyloxypropylammoniummethylphosphite BF-53 2-methoxyethylammoniumethylphosphite BF-76

Example 8

Corn was sown in culture bottles (5 plants per bottle) and, after emergence, sprayed with solutions containing the test substances on Gibberalic acid or 3-indole acetic acid, at concentrations of 250 and 500 ppm. Plant length, green mass and root mass were measured when the untreated plants were at the 4-leaf stage; these results are shown in Table II. The chlorophyll contents of each second leaf (counted from the top) were determined; these results are shown in table III.

From the results, it is clear that the development of the plants, compared to the untreated plants, was significantly enhanced by each of the test substances.

However, the ratio between plant height and green mass gives a clearer indication of the effect of the BF substances compared to that of the comparative substances. For example, the habites of the corn were found not to be adversely affected by BF-12Q or FR-96, while under the influence of gibberellic acid plants with detrimental habites were produced for a relatively long time.

From the results of the chlorophyll determinations it appears that BF-120 had the most favorable effect on the amount of chlorophyll per gram of green plant as in the total plant.

15 Example 9

Tomato plants distributed in small plots were sprayed initially with solutions containing 250 or 500 ppm BF-120 from flowering to dripping. One day, four days and thirteen days after the treatment, samples were taken from the same leaf lobe at the same leaf height and the chlorophyll was determined therein. The results are shown in Table IV.
