Abstract

Chloropicrin in 1 cc. doses is lethal to bulb nematodes at six inches from the point of injection or within a soil volume of one cubic foot. It is also lethal to fungi. The vegetative stages are destroyed at 1:195,000, and certain sclerotia at 1:90,000.The injection of chloropicrin into greenhouse soils lowered the incidence and pathogenicity of a root-knot infection on both a summer and winter crop of tomatoes and greatly increased the yields of fruit. The chloropicrin costs $1.65 per pound or $8.50 to treat 2000 sq. ft. of soil.
