Efficacy of bio agents and fungicides against collar rot and early leaf spot of groundnut

摘要

Collar rot caused by ( Aspergillus niger Van Teighem) and early leaf spot caused by ( Cercospora arachidicola Hori) are the two major diseases, affecting the groundnut cultivation across the India and worldwide. The main aim of this study was to find out the effective management module to control the collar rot and early leaf spot diseases of groundnut. Efficacy of bio agents and fungicides either alone or with combination were assessed under field conditions. The treatment module consisting of seed treatment with Tebuconazole 2 DS @ 1.5?g?kg_(?1)+ furrow application of T. viride @ 4.0?kg enriched with 50?kg FYM ha_(?1)+ broadcasting of T. viride @ 4.0?kg enriched with 50?kg FYM ha_(?1)at 40 DAS + two foliar sprays of Tebuconazole 25.9% EC @ 1.0?ml?l_(?1)starting from initiation of diseases and second spray at 15?days intervals was found most effective and economically beneficial treatment module in controlling of collar rot and early leaf spot diseases of groundnut.
