Abstract

Trichoderma harzianum Rifai application either to soil as wheat bran saw dust (WBSD) preparation or on the groundnut seeds as spore coat proved effective against selerotium wilt caused by Sclerotium rolfsii Sacc. Synergistic and positive effects on disease control were registered when T. harzianum-WBSD preparation was applied to soil in integration with Vitavax or Vitavax-200. Integration of Thiram (seed coating) and soil application of antagonist was found compatible and synergistic. However, seed treatment with both antagonist and Thiram was found incompatible and hence may not be practically feasible for disease reduction.
