EFFECT OF BIOCONTROL FORMULATIONS AND CHEMICAL FUNGICIDE (BAVISTIN) ON DAMPING OFF DISEASE AND GROWTH PARAMETERS IN ACACIA CATECHU (KHAIR )

B. M. Ojha

Abstract :

A study was carried out to find the effect of biocontrol formulations and chemical fungicide (bavistin) on damping off disease and growth parameters in Acacia catechu (khair). It was found that there was a progressive reduction in seed germination, seedling growth, biomass and survival with the increased level of infection. Aspergillus terreus (At), Penicillium herquei (Ph) and Trichoderma virens (Tv) were tested in laboratory and field conditions for their antagonistic potential against Fusarium sambucinum var.coeruleum. Feasible biocontrol formulations and delivery system of these antagonists have been prepared in powder form using bagasse for field applications. The biocontrol formulations were found successful in controlling the disease and also compared with chemical fungicide (bavistin) treatments. Seed pelleting and soil mixing with Tv formulations was found superior among the biocontrol formulations in reducing the disease incidence which were at par with the fungicidal treatments. The same trends were also found in SVI and SVIN values.
