Preplant fumigation for sugar beet nematode on cabbage

Abstract

Preplant fumigation with 1,3-dichloropropene and related chlorinated C3 hydrocarbons and Agel TG-67 significantly increased cabbage yields over the untreated check where the nematode Heterodera schachtii was present in high numbers. Some weed control was also obtained with the Agel formulation. The high nematode populations present in the soils in the fumigated plots at the end of the growing season showed the need for rotation or annual fumigation if a susceptible crop is to be grown on infested land.
