Abstract

The article considers the application of plant growth and development regulators, in particular, derivatives of asymmetric triazines. A method for obtaining hexahydro-1,2,4-triazinone-3 is given. Optimal conditions for the reaction of 1,2-dichloroethane with semicarbazide are determined: reaction time, process temperature, and the effect of solvents on the yield of the target product. The results of laboratory and vegetation tests of 1,2,4-triazinone-3 for biological activity are presented. Laboratory studies were carried out on seeds of wheat, cucumbers, radish and vetch, which were laid out in Petri dishes and poured with a working solution, the concentration of the drug is 1, 10 mg/l. Two days later, the length and weight of etiolated seedlings were determined. Vegetation tests were carried out on seeds of barley, wheat and rye with a concentration of 10 mg/l. After two weeks, the length and weight of the plants were measured.

Highlights

In agriculture, plant growth and development regulators (PGDR) are widely used in practice
More environmentally friendly for humans and the environment are the asymmetric triazines, which are decomposed in the environment as they do not suppress the activity of nitrification and nitrogen-fixing bacteria, are relatively low-resistance in environmental objects and are relatively rapidly decomposed to form the simplest products [5,6,7,8,9]
A three-necked flask equipped with a mechanical stirrer, reflux condenser and dropping funnel was charged with 30 ml of dimethyl sulfoxide (DMSO); 5.57 g (0.05 mol) semicarbazide, 5.3 g (0.05 mol) sodium carbonate; 7 ml (0.09 mol) of 1,2-dichloroethane

Summary

Introduction

Plant growth and development regulators (PGDR) are widely used in practice. Of particular interest from the point of view of the efficiency of the growth-regulating properties are nitrogen-containing heterocycles, in particular derivatives of symmetric and asymmetric triazines. Compounds of symmetric derivatives have found practical application, they are difficult to biodegrade and accumulate in the soil, and as a consequence in the plants itselves. More environmentally friendly for humans and the environment are the asymmetric triazines, which are decomposed in the environment as they do not suppress the activity of nitrification and nitrogen-fixing bacteria, are relatively low-resistance in environmental objects and are relatively rapidly decomposed to form the simplest products [5,6,7,8,9]
