RESEARCH OVERVIEW

Abstract

In our study, the fungicide Koritus WG (0,4 kg / ha) was tested against powdery mildew found in pear orchards. The study showed a high biological effectiveness of the applied fungicide against dew disease from pear flour. Damage to leaves was from 7,1%, fruits - from 6,2%. The development of the disease ranges from 5,7 to 6,4% in leaves, and in fruits from 3,9%. The biological effectiveness ranged from 89,8% to 90,3%.
