Abstract

Qualitative structure sugar-beet nematode populations Нeterodera schachtii Schmidt provided the cultivation of spring rape. It is established that such factors as gap-fillingness cysts, the number of viable, vain and affected micromycetes cysts depend on temperature factors, host plant, the action of chemical and biological agents and characterize the viability nematode populations in agrocenoses investigated.
