PL99324B1 - AGENT FOR STABILIZING CEREAL PLANTS - Google Patents

Description

The subject of the invention is an agent for stabilizing the stalks of cereal plants, improving the bedding resistance of these stalks without adversely affecting the yield. It is known that combinations of alkali metal salts and ammonium salts of 2,3-dichloroisobutyric acid and chlorocholine chloride will develop in wheat, rye and barley - it shortens the tooth and therefore stabilizes the tooth. It is also known that by the use of 2-chloroethylphosphonic acid in life and barley an increased resistance to lodging is obtained. All these active substances or combination preparations, however, suffer from a number of disadvantages, for example: a) None of the preparations mentioned are equally effective in all types of cereals, but in addition to the above-mentioned "... oats must also be considered. 3) In the case of rye and barley, the stabilizing effect of the toothbrush under high nitrogen doses is not sufficient to protect the vegetation from lodging in a certain way. * C) 2-chloroethylphosphonic acid should be applied relatively late, which leads to technological difficulties in application (plots of high vegetation are difficult to reach for agricultural implements). «d) In case of inadequate application and unfavorable climatic conditions (drought), there is a possibility of overdosing damage, for example deformation of leaves relatively disturbances in fertility (the last one, especially in the case of rye). The aim of the invention was to invent gum stabilizers even action on wheat, rye, barley and oats, which could be applied early in time \ who. re would not show disadvantages of known solutions. It was necessary to develop active substances or combinations of active substances which would control the growth of the cereals in such a way as to achieve the desired goal also with high doses of nutrients. Moreover, these preparations should be without reservation from a toxicological point of view. It has been found that admixing a small amount of an ethylene-producing compound with 2,3-dichloroisobutyric acid or its salt or a mixture of 2,3-dichloroisobutyric acid or its salts and chlorocholine chloride leads to preparations having the above-mentioned characteristics, since ethylene affects the transport of the active ingredient in the plant. The ethylene-producing compound used is, for example, 2-chloroethylphosphonic acid. The stabilization of the stalk of cereal plants is achieved with the aid of an agent containing known auxiliaries and carriers as well as an active ingredient which, according to the invention, contains acid as active ingredient 99 32 499 324 3 4. 2,3-dichloroisobutyric chloride, (2-chloroethyl) -trimethylanionium chloride, and an ethylene forming compound such as 2-chloro-ethylphosphonic acid, whereby the acids mentioned may also be in the form of alkali metal or ammonium salts. Particularly preferred ratio 2,3-dichloroisobutyric acid to 2-chloroethyl • phosphonic acid or its salt and to (2-chloroethyl) -trimethylammonium chloride is about 1: (0.25 to 0.5) :( 0.2- 1.0). In the treatment of oats, 2-chloro-ethylphosphonic acid can be omitted so that the treatment is carried out only with 2,3-dichloroisobutyric acid or its salt and (2-chloro-ethyl) -trimethylammonium chloride, the hundred The ratio of both compounds is approximately 1: (0.25-0.5). The treatment of the plants is already successful at a growth height of 25-30 cm. The amount of active substance should not exceed 7 kg per hectare. A sufficient shortening of the tooth is then achieved with great certainty, without damage from overdosing. This is a prerequisite for the full exploitation of the yield potential with the highest nitrogen doses. Spray liquids are prepared in a known manner, with the possible addition of known adjuvants. By using the new combinations of active substances in the method according to the invention, the growth of all types of crops, especially Wheat, rye, barley and oats in such a way that a bed resistant to lodging is obtained and a high yield is obtained with the addition of appropriate nutrients. The amounts of the active substances used are relatively low, so that no PL is present

reservations of toxicological nature. The possibility of early application, already at a plant height of 25-30 cm, is also very advantageous from the technological and economic point of view. The following examples explain the invention. For simplicity, the following abbreviations are used: DCiB = 2,3-dichloroisobutyric acid (or its salt) 2-CAPS - 2-chloroethylphosphonic acid (or its salt) CCC - (2-chloroethyl) -trimethylammonium chloride (chlorocholine chloride) ) MB = mean height of vegetation LB = lodging. The values for lodging are determined such that 1 is straight standing and 9 is complete lodging. The tooth shortening is sufficient when it is 20% or more. Example I. In field trials, the root shortening effect, or the root stabilizing effect of a combination of DCiB and 2-CAPS with and without CCC admixture in rye, wheat, barley and oats, as well as combinations of DCiB with CCC in oats are investigated. As a control, plots with an area of 18 m.sup.8 were used in four times. The sowing and cultivation of the cereals is carried out in a known manner using the most favorable agrotechnical terms. Phosphorus-potassium fertilization is carried out in accordance with the fertilization recommendations. The amount of nitrogen doses is given in Tables 1–3, while nitrogen fertilization is carried out in at least 2 partial doses. The active substances are sprayed in the form of 5 kg / ha in aqueous solutions over plants with a height of 25-30 cm. In the experiments with 2-CAPS alone, only 2 kg of active ingredient per hectare were used, as larger amounts are toxic. Tables 1–3 2 summarize the results of the experiments.
