Abstract

1. A process for regulating the growth of plants, with the exception of cotton plants and cereals, wherein the plants are treated with an N,N-dimethylpiperidinium salt in an amount of less than 500 g of active ingredient per hectare.

Description

The present invention relates to β, β-diaethylpiperidine salts for regulating plant growth.

It is known to use N, N-diethylpLpMrLdiniovd salts applied in the range of 0.5 to 8.0 kg / ha to reduce the height of plant growth (cf. DOS 2 207 575).

It is further known to use N, N-dimethylpLpHHL < l > Linium salts applied in an amount of from 5 to 24.5 g of active ingredient per hectare to treat cotton plants in order to reduce the yield. . growth (cf. DOS 2,815,345).

Poitive effect It can be observed in experiments with tomatoes and potatoes and the fluctuating effect on cereals, grasses, rape, soya beans and sugar cane. In addition, it is known that X, N-methylpiperidine chloride has a good effect in the application of a quantity of from 25 to 100 g of active ingredient per hectare in cotton (cf. Markbbitt der BASF Wndtte Corjpraticn, USA, cited in 1978).

It has now been found that by treating the plants with the exception of the tevloid plant Ν, K-dimethyl] β] -depole salt applied in mute. less than 500 g of active substance per ha does not occur. nor does it increase the height of the plants, but there is a prooaw effect in stimulating plant growth. In this case, the N, N-dimethylpiperidium salts can be counted to a group of regulators which, and quantitatively, affect biological processes - development.

For example, the effect can be:

- an increase in the production of dry matter of vegetative parts of plants;

- change ratio of the mass ^b mo0nootního vegetative organs: organ mass gmoHritlvoích benefit geoerativních bodies;

- enlargement of the information area;

increasing the production of substances contained in the plant, for example starch, soluble amino acids, terpenoids, essential oils, latex, alkaloids;

- reduction of undesirable substances in the plant, such as alphatoxia, gossypol, liaolea;

changing the concentration of ions in the growing tissues and thus 1 resistance to occlusion;

- production of fruit without seeds without eight dreams;

- intensify! pigment formation;

- improvement of the inside and more of the fruits;

- shortening the developmental cycle, affecting the maternal maturity.

Salts are, for example, salts of halofluorocarbons, for example chloride, or salts of sulfuric acid, acetic acid or phosphoric acid. Chloride is preferred.

Particularly good efficacy is observed, for example, in tuberous fruits, amniotic vegetation, non-nematic fruits, pumpkin crops, leafy vegetables, oleaginous plants, pumpkin plants and citrus fruits. ¹

Preference is given to using from 1 to 450 g of active compound per 1 ha, preferably from 10 to 200 g of active compound per 1 ha.

Examples of biological activity may be as follows. results from field trials. These experiments were carried out with 4-repetition repetition and on plots of 25 to 50 m < -1 >. All plant treatments were sprayed using an aqueous solution of the active ingredient and green plants.

I. Tuberous plants, such as potatoes, sweet potatoes:

Examples 1 to 4

In experiments with 4 different potato species, 25 g / ha of Ν, Ν-dimethylpiperidinium chloride is applied 60 days after planting, at the beginning of tuber formation, to the leaves of the plants. The results obtained show that the treatment results in an increase in the assimilation area, an increase in the dry matter production of the leaves, stems and tubers and finally an increase in tuber yield. From this we can deduce increased production of starch and biocase.

Electrical Resistance Measurements Taken 15 1/2 hrs Later Indicates the nominal conductivity in treated fruits. Less conductivity is directly related to the smaller amount of free electrolytes, from the cells damaged by the cooling and thus to the lesser damage caused by the cold. It is known that calcium ions have a substantial function in cell wall formation.

Ν, Ν-dimethylplperidinium chloride increases the content of calcium ions and hence resistance to cold.

By varying the content of substances in the cells, for example by increasing the concentration of ions, the resistance to human eye is increased.

These salts can also be used together with other plant protection agents, i.e. together with herbicides, insecticides, synergists, antdotes, other growth regulators, in particular also fungicides. For practical use, it is also advantageous to use these salts together with a fertilizer, in particular a mixture with ureas.

The effectiveness of the salts is cation dependent, so the choice of anion is arbitrary. Phytotoxic acid anions should not be used.

Suitable acids are, for example, hydrochloric acid, hydrobromic acid, sulfuric acid, carbonic acid, nitric acid, phosphoric acid, acetic acid, propionic acid, benzoic acid, monomethyl ester or monoethyl ester of sulfuric acid, 2-ethylhexanoic acid, acrylic acid, maleic acid, succinic acid , adipic acid, formic acid, chloroacetic acid, p-toluenesulfonic acid, benzenesulfonic acid, dodecylbenzenesulfonic acid. The hydrochloric acid salt is preferred.

These salts may be administered in a single dose or divided into sub-doses (i.e., at different time periods).

These salts can be used in the form of solutions, dispersions, emulsions, suspensions, granulates, foams or dusts. The use forms depend entirely on the intended use. These forms are intended in each case to ensure a fine distribution of the active ingredient. The application can also be carried out via seeds or on green parts of plants.

A solution in water is suitable for the production of directly sprayable solutions. Dispersions in hydrocarbons boiling above 150 ° C and with one or more functional groups, for example keto, ether, ester or amide may also be used as spray liquids, which may be a substituent on the hydrocarbon chain or it may be a heterocyclic ring component.

Aqueous use forms can be prepared as emulsion concentrates, pastes or wettable powders by the addition of water. In order to prepare emulsions, the active compounds as such or dissolved in a solvent can be homogenized with wetting or dispersing agents, for example, polyethylene oxide edition products in water or in organic solvents. However, concentrates may also be prepared which consist of the active ingredient, an emulsifier or a dispersant and optionally a solvent. Such concentrates are suitable for dilution with water.

Dusts can be prepared by mixing or co-grinding the active ingredients with a solid carrier, for example silica gel, talc, clay or fertilizer.

In the case of granules, mixtures with fertilizers are preferably used.
