    Sugar beet is one of the economically significant industrial crops for the south and southeast of Kazakhstan. In the conditions of Kazakhstan, the best predecessors of sugar beet are winter wheat and alfalfa, which contribute to the improvement of the susceptibility of beet rot. Early plowing by the semi-pair type in the second decade of August allows reducing the susceptibility of root crops to Fusarium rot by 18%. It is shown that 6 centner/ha of wheat straw on the artificial background contributed to decrease in the prevalence of Fusarium rot, on average 1.4 times, Rhizoctoniosis rot – 1.2 times compared with the control. Increasing the rate of nitrogen and phosphate fertilizers contribute to the development of root rot (2-3 times) of sugar beet. To reduce the severity of rotten root crops (from 1.3 to 2.5 times), 6 t/ha of wheat straw are proposed to be applied to the soil together with N90P75K70. Seed treatment with tachigaren seed, rovral and fundazol reduces the development of rot by 8.1-16.6% and leads to an increase in yield of root crops by 31.5-50.2 c/ha.

    Drillers used for agricultural crops, in particular cotton seeds, cannot provide additional nitrogen feeding in the required volume during a shortage of nitrogen fertilizers. This article sets the task of creating a new active substance based on the phyto compound dimethylolure and molybdenum, which allows you to reduce cotton diseases in cotton cultivation, increase the accumulation of light hydrolyzed nitrogen in the soil and obtain a high cotton yield. The purpose. Study of chemical interactions in a three-component aqueous-salt system of dimethylolure-molybdenum phyto-compound-water by isothermal method. Objects. DMM, FSMo, double compound DMM is the active reactant of FSMo. Results.The isothermal method at a temperature of 25°C found that in the concentration range of solutions of 12.2-9.8% DMM and 2.8-5.4% FSMo, DMM crystallizes in the system, at a concentration range of 5.7-2.1% DMM and 12.3-15.5% FSMo, FSMo crystallizes, and in the concentration range of 8.2 -6.4% DMM and 6.2-9.3% FSMo, the compound DMM•FSMo is separated from the solution into this phase.Conclusion. The chemical interaction in the water-salt system dimethylol urea (DMM) - molybdenum phytocompound (FSMo) - water was studied by isothermal methods of chemical analysis. The region of crystallization of a new double compound, an active substance based on DMM and FSMo, was established at a molar ratio of 4DMM•FSMo. On model soil samples, it was determined that the active substance - the double compound 4DMM•FSMo against the background of ammonium nitrate, in comparison with ammonium nitrate, increases the number of nitrogen-fixing bacteria by 3.0 and 3.2 times.
