Abstract

This Study was conducted to evaluate the compatibility between nutrient element and fungicides to induced systemic resistance against damping– off of cucumber seedlings incited by Pythium aphanidermatum, under greenhouse condition. It was found that integration between Ridomil 2.5 G with salicylic acid and silicon or calcium nutrient and Beltanol with salicylic acid and silicon ,and salicylic acid with silicon significantly reduced damping off and disease severity to 0.00, 1.66; 0.00, 6.66; 0.00, 6.66 and 0.00, 3.33% respectively, Compared to control treatment (Pathogen only) which caused 86.66, 85.00% respectively. Over that, these treatments caused significant increase in dry weight of shoots and roots. These results revealed to apply fungicide and nutrient element in IPM program to control the pathogen.
