Powdery mildew incidence and harmfulness in peas under conditions of belarusian Wodlands

Abstract

   In 2008–2009 in the belarusian Polesie conditions there was widespread powdery mildew damage of pea crops. The appearance and development of the disease is promoted by the alternation of hot weather and a moderate amount of precipitation. Under favorable weather conditions, powdery mildew appears during the flowering period or the beginning of the bean formation. During heavy rains, a part of the conidia of the pathogen is washed away, as a result of which the infectious load decreases. In the еpiphytotic development of powdery mildew, the pea yield is reduced by 57,3–76,4 %, with moderate – by 19,2–38,2 %.
