Biological control of cotton wilt

I. Soil fungistasis and antibiosis in cotton fields

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

An assay of “wilt-sick” and “wilt-free” soils from cotton growing areas revealed the fungistatic nature of the latter soil to the wilt pathogenFusarium vasinfectum Atk. Screening of the soils for antibiotic producers, revealed that the “wilt-free” soil harbours far more microorganisms antagonistic to the fungus than the other, leading to enhanced “antibiotic index” and “antibiotic value” over the other soil. Among the microorganisms isolated from these soils, actinomycetes were the most potent antagonists.
