Effect of soil disinfection and diffusion of chloropicrin applied into the mulched row were investigated under various moisture contents in sand soil. Soil disinfection by chloropicrin under high moisture content in sand soil showed high efficacy on the disease occurrence. Chloropicrin in the mulched row diffused thoroughly upper and lower part under enough soil moisture content, though the chemicals under low soil moisture content of sand soil could not diffused lower part of injection site. Diffusion of chloropicrin under moisture content over 6% in sand soil brought stable control effect on the disease.
