Role of resistance inducing chemicals against soybean dry root rot (R. bataticola) disease

Abstract

All of the test ISR chemicals, applied as seed treatment and foliar spray (alone and in combination) and the standard check fungicide Carbendanzim 50 % WP seed treatment @ 1g/kg seed were found to reduce significantly soybean dry root rot incidence, over untreated control. However, the most effective treatment found was Salicylic acid ST + it’s FS, with significantly highest reduction in average mortality (92.90%), followed by Chitosan ST + it’s FS (89.34 %), Salicylic acid ST (86.88%), β-amino butyric acid ST + it’s FS (85.89%), Chitosan ST (82.63%), β-amino butyric acid ST (80.64%), Jasmonic acid ST + it’s FS (77.62%) and Jasmonic acid ST (72.85%) and Carbendazim (53.16 %).
