Goal. To study the effect of Urea on the properties of working solutions of emulsions and suspensions of chemical and microbiological drugs in plant protection against pests. Methods. Information-analytical analysis of the effectiveness of joint use of insecticides with Urea. Laboratory experiments on the effect of Urea on: evaporation of droplets from the treated surface; surface tension; reaction of the medium of suspensions and emulsions of working solutions of chemical and microbiological preparations. To do this, in aqueous solutions of insecticides and biological products in concentrations recommended for use in field crops, was added 0.2% aqueous solution of Urea. After a certain period of time, the characteristics of the solutions were determined. An analytical generalization of the change in the properties of working solutions under the influence of urea is carried out. Results. The information on the possibilities of joint use of insecticides and microbiological preparations with Urea in a single technological process is generalized. Their combination leads to a significant reduction in the evaporation of solution droplets from the treated surface, but does not affect the surface tension and reaction of the solutions. Conclusions. Urea is an active anti-evaporator of working solutions of insecticides of various nature. Adding it to the solutions of evaporation of drops from the treated surface reduces more than 1.5 times. It does not significantly affect the surface tension and reaction of the solution. This characteristic of the solutions is maintained for 24 hours after preparation.

Goal. Substantiate the use of environmentally friendly means of protecting peas with modern technologies of crop cultivation. Methods. Field, laboratory, mathematical-statistical, calculation. Results. The relationship between the spread of diseases and the main environmental factors (temperature and humidity, atmospheric precipitation) during the growing season of plants has been investigated. The terms and norms of processing with biological products and their effectiveness have been established. Methodological recommendations have been developed for the use of environmentally friendly means of protection, which are based on the use of biological preparations in pea agrocenoses and in the production of organic products. Conclusions. In agrocenoses of peas, the use of biological plant protection products for the production of organic products is recommended.
