The fungicides like propioconazole 25% EC, propineb 70 WP and tebuconazole 50%+ trifloxystrobin 25% WG (effective against FOG) completely resisted the growth of NVTH2. Finally, a field experiment was designed by utilizing 3 most efficient Trichoderma spp. and 4 fungicides in combination treatments. As a result, root dipping+ soil drenching with NVTH2 @5ml/ lit followed by soil drenching of tebuconazole @lml/Iit at fortnight interval alternately resulted in highest yield, growth promotion and percent inhibition of wilt incidence. 收起
