Biological control of cotton wilt

III.In vivo effect of antagonists on the pathogenFusarium vasinfectum atk

  • Published:

Abstract

By adding optimum dose of propagule suspension of antagonistic actinomycetes to pathogen amended sterilized soil, control of wilt in cotton could be effected. Gradual elimination of the pathogen both in rhizosphere of the host and soil was noticed in the presence of antagonists. Incorporation of antagonists directly into the soil controled the disease to a greater extent than “seed treatment” with propagules of antagonists. Efficient control of the disease was observed only with a few of the antagonists when seeds were soaked in their metabolites and sown. Significantly these were fromFusarium “wilt-free” soils.
