EVALUATION OF FUNGICIDES, BIOAGENT AND PLANT EXTRACTS AGAINST FUSARIUM OXYSPORUM F.SP.MELONGENAE CAUSING BRINJAL WILT ON DIFFERENT VARIETIES UNDER GREEN HOUSE CONDITION

Abstract

Brinjal (Solanum melongena L.) is an important vegetable crop in India. This crop is affected by many diseases. Among
them wilt disease is one of the most common diseases of brinjal caused by Fusarium oxysporum; a soil borne fungus. The
present investigation therefore was carried out to evaluate the effects of fungicides, bioagent and plant extracts, against
this pathogen. Two fungicides (Bavistin and Mancozeb) one bio-agent (Trichoderma viride) and two plant extracts (Allium
sativum and Allamanda cathertica) were tested against the disease in in vivo condition. Among the treatments applied in the
presents experiments, Bavistin, Mancozeb and Trichoderma viride showed 100 percent reduction of wilt disease in all the
three varieties; while Allium sativum and Allamanda cathertica extracts showed (V1= 81.2, V2= 69.8, V3= 76.8)% and
(V1= 62.4,V2= 39.7,V3= 53.7) percent reduction respectively over control.
