SU1519614A1 - Means for regulating wheat growth - Google Patents

Abstract

The invention relates to agriculture, namely to chemical means of controlling plant growth. The purpose of the invention is to increase the growth regulating activity. For this, the 2-chloroethylphosphonic acid-based agent additionally contains dimethylaminomethane-bis-phosphonic acid in a ratio of 1-3: 1-2. The tests were carried out on winter wheat "Mironovsk 808" and Khatri wheat in laboratory experiments by soaking the seeds and immersing the leaflets of 14-day plants in solutions containing 2-chloroethylphosphonic and dimethylaminomethane-bis-phosphonic acid, taken in a ratio of 1- 3: 1-2. In this case, a reduction in the length of the stem is observed as compared to untreated (control) plants and with plants treated with each compound separately, i.e. the use of a mixture of drugs gives a synergistic effect, increases the resistance of wheat to lodging, table 3.

Description

The invention relates to agriculture, and to chemical means for regulating the growth of wheat.

The use of 2-chloroethylphosphonic acid as a means for regulating the growth of wheat plants is known (USSR Patent No. 298093, CL A 01 N 57/20, 1967).

However, this tool is not effective enough.

The purpose of the invention is noBbinjeHHe growth regulating activity.

This goal is achieved by the fact that the agent based on 2-chloroethylphosphonic acid additionally contains dimethyl-aminomethane-bis-phosphonic acid in a ratio of 1-3: 1-2.

An example. Grain winter wheat varieties "Mironovska 808 withstand

within 24 hours in a solution of dimethylamino. methane-bis-phosphonic acid (compound A) and in a solution of 2-chloroethylphosphonic acid (compound B) and germinated. At the end of the day, seedlings are transplanted to a hydro-culture. After 6 days of them measure the length of the shoot, development, and a.-gallium.

The data presented in Table. I.

Example 2. In a conditioned jung, the grain was treated with compounds A and B. As test plants, durum wheat (Khatri variety) was used. Solutions of compounds A and B were poured into Petri dishes and the leaf plates of 14-day plants (stage 2 leaves) were slowly immersed in the solution. Then the plants were again stirred into the culture vessels. The analysis was carried out through
