Efficacy of antagonists, oil cakes and fungicides against Fusarium wilt disease in brinjal

Abstract

An investigation was conducted to demonstrate the efficacy of different antagonists, oil cakes and fungicides with known activity against brinjal vascular wilt, Fusarium solani. Three different antagonistic genera viz., Bacillus sp., Pseudomonas sp. and Trichoderma spp., seven different oil cakes, and four different commercial fungicides were tested against the pathogen under in vitro and field conditions. Among the Pseudomonas isolates tested in vitro, Pf2 was most effective against the pathogen. Among Trichoderma sp. tested in vitro, TV1 was most effective against Fusarium solani. The isolates of Bacillus sp. screened for antifungal activity against Fusarium solani Bs1 was most effective against the pathogen. Among the oil cake extracts tested in vitro, neem cake extract (5%) effectively reduced the growth of F. solani. Among the fungicides tested in vitro, carbendazim at 500 ppm was most effective against F. solani. The effective antagonists, organic amendments and carbendazim were screened in vitro and further confirmed in pot culture experiments. Results of the pot culture experiment indicated that soil application of T. viride (SA) @ 2.5 kg·ha-1 had the maximum disease reduction over control. The most effective treatments, and their combinations, screened in laboratory and pot culture were tested against F. solani under field condition. Results of the field experiment indicated that treatment with T. viride (SA) @ 2.5 kg·ha-1 had the maximum disease reduction over control and improved plant growth and yield of Brinjal (35.0 Mt.ha-1)
