Fungicidal control of powdery mildew in field pea

Abstract

The efficacy of sulfur (Kumulus S) and myclobutanil (Nova 40W) fungicides for control of powdery mildew (Erysiphe pisi Syd.) in field pea (Pisum sativum L.) was investigated in field trials at two locations in Manitoba in 1994 and 1995. Both fungicides were effective in reducing disease severity and increasing seed yield and seed weight of the susceptible cultivar Radley. Fungicide treatments were economically beneficial when disease pressure was high.
