Damages from apple leafcurling midge (Dasineura mali Kieffer) on apple in three growing systems
Vilina Petrova
Abstract: The aim of the study is to determine damages of apple leafcurling midge Dasineura mali Kieffer in three growing systems - conventional, integrated and biological. The investigations were carried out in an experimental apple orchard (1 ha) of the Institute of Agriculture at Kyustendil, in four consecutive years (from 2009 to 2012). Three scab resistant cultivars ‘Prima’, ‘Florina’ and ‘Erwin Baur’ grafted on rootstock MM 106 were planted in 1996. During the experimental period the highest percentage of damaged shoots and leaves was established in the integrated technology and the lowest percentage was established in conventional technology.
