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.
