Application of SAR Activator for Management of Pea Powdery Mildew (Erysiphe polygoni)

Powdery mildew of pea is one of the foremost diseases of pea incited by Erysiphe polygoni DC. Present study conducted to find out the comparative performance of SAR activators for control of powdery mildew. An experiment was conducted at farm of SKNCOA, Jobner during Rabi season 2021. Five SAR activators along with control viz. ethylene (100 ppm), salicylic acid (250 ppm), hydrogen peroxide (200 ppm), fosetyl al (1000 ppm) and benzothiadiazole (1000 ppm) were applied as two foliar sprays. During evaluation, all the treatments were found effective against powdery mildew of pea but Salicylic acid (250 ppm) and Fosetyl AL (1000 ppm) were found as best treatment to control powdery mildew disease of pea.
