Development, spread of root rot on plowing, disking and direct sowing

Abstract

The results of the study showed that various methods of tillage affect the population of the soil with pathogens. Less populated was the soil where traditional tillage was carried out - autumn plowing. With this treatment, in the 0-10 cm layer, the soil colonization with root rot conidia was lower than with minimal tillage and zero sowing. In the 10–20 cm layer, the same trend persisted. The presence of conidia of the genus Alternaria was observed mainly in layer 0-10; 0-20cm and was negligible. At zero sowing, the conidia in the 10-20 cm layer were mostly semi-decomposed.
