Characterization of favorable weather conditions with powdery mildew disease incidence on pumpkin

Abstract

Weather variables were characterized for the powdery mildew disease caused by Sphaerotheca fuliginea on pumpkin crop. The relationship between airborne conidia and incidence of powdery mildew on pumpkin was studied. Disease incidence data was recorded on weekly basis and correlated with prevailing environmental conditions.  All the environmental factors showed positive relationship with disease incidence except wind speed that exhibited negative correlation. Understanding of favorable environment is helpful to use appropriate management approaches.
