PL99092B1 - AGENT FOR REGULATING THE GROWTH OF PLANTS - Google Patents

Description

The subject of the invention is an agent for regulating the growth of plants, especially for influencing the growth in length and thickness of cereals. It is known that plant growth regulators affect a variety of receptors and depending on the stage of plant development, the method of application and the duration of application, and Various reactions may occur depending on the concentration of the active substance and the type of preparation. For example, it is possible to control vegetative and sexual budding, flowering, sex determination and parthenocarpy. Various active substances used to influence plant growth are known, including 2-chloroethane phosphonic acid, chlorocholine chloride, succinic and maleic acid hydrazide. The main disadvantage of these substances is their relatively limited intensity of action. The aim of the invention was to develop an agent for regulating growth of plants, in particular that has an effect on the growth in length and thickness of cereals, and has a wide range of action. This is achieved with a measure according to the invention which contains, in addition to the usual auxiliaries and carriers, 2-chloroethanephosphonic acid as active ingredients and chlorocholine chloride. The addition of non-nitotoxic oils has also proven advantageous, since in this way a further increase in the action of the agent according to the invention is achieved. Depending on the application, the agents according to the invention may be in the form of solutions. oil emulsions, suspensions, powders, pastes or granules. The following examples illustrate the invention. Example 1 Cereals are treated in a greenhouse with an agent according to the invention. Spring wheat (Carola species) and spring barley (Galina species) are used as test plants. Plants in the 2-leaf stage are treated with an agent according to the invention having a concentration of 1% of active ingredient. After 4 weeks from the beginning of germination, the results are determined by measuring the stem between the first and second leaves. The results are summarized in Table 1. Example II. In field trials, spring wheat (Mironovskaya grade 808) at the Feeke stage 7) is treated with the agent according to the invention. The total amount of active ingredient is suspended in water, using 600 liters of water per hectare. After the shifting of the lobes is finished, the growth height and phytotoxic effects are determined. The results are summarized in Table 2. PL
