THE ROLE OF PRECURSORS IN REDUCING THE HARMFULNESS OF FUSARIUM ROT OF SUGAR BEET ROOTS

Long-term studies of the zone of sugar beet cultivation in Kazakhstan show that the shorter the interval between beet crops in one place, the greater the risk of contamination with root rot. So on farms where beets were returned to the previous site in 1-2 years, the prevalence of rot was as high as 78.9%. The least manifestation of rot was observed in crop rotations, where the beet was returned to its former place no earlier than 8 years or more, that is, the field was virtually free of soil infection. Here, the affection of root crops was 9.8%, which in turn contributed to an increase in yield (334-425 q / ha).
