Abstract
Apple powdery mildew (Podoshphaera leucorticha) occurs wherever apples are grown. One of the most important fungal disease of apple which causing severe econimic loss on susceptible apple cultivars. This review focuses on the control of apple powdery mildew. The first part of the study provides details of novel aspects of non-chemical control approaches, including agronomic measures, mechanical and biological control options as well as essential features of apple cultivar resistance. After this, developments in chemical control options are described sperately for integrated and organic apple orchards.
Highlights
Apple powdery mildew (Podoshphaera leucorticha) is a wordwide known fungal pathogen of apple
The aim of this review was to prepare a summary for control of apple powdery mildew including agronomic measures, mechanical, biological control and chemical control options in integrated and organic apple orchards
Recent develop ments in non-chemical control options are listed and their efficacy is evaluated on apple powdery mildew
Summary
Apple powdery mildew (Podoshphaera leucorticha) is a wordwide known fungal pathogen of apple. A key important fungal disease of apple which causing severe econimic loss on susceptible cultivars in every years where apple are grown (Hickey and Yoder, 1990; Holb, 2013). Control of the pathogen is widely investigated all over the world in the past 100 years. Thousands of publications were aimed to investigate the possibilities of control and to improve powdery mildew forecasting and disease management. The management of powdery mildew of apple and pear requires consideration of cultivar susceptibility, the desired market quality of the fruit, and the importance of other diseases to be controlled. The aim of this review was to prepare a summary for control of apple powdery mildew including agronomic measures, mechanical, biological control and chemical control options in integrated and organic apple orchards
