The efficiency of some insecticides used for controlling Grapholitha funebrana Tr. and Eurytoma schreineri Schr. pests, in the plum tree plantations

Abstract

During 2002 – 2003, according to the observations on the biology and ecology of Grapholitha funebrana Tr. and Eurytoma schreineri Schr. species, we have studied the efficiency of insecticides for controlling these species. We have tested the insecticides from synthetic piretroids, organophosphoric, carbamic group, metamorphose inhibitors, and biological products. All the products had a great efficiency, the best results being obtained by Cypermetrin 10CE – 0.05%, Victenon 50WP 0.1% and Karate 2.5CE – 0.03%, where the attack degree in fruits was between 0 - 1%. The biological products Dipel and Bactospeine had a lower efficiency, and the degree of attacked fruits was comprised between 19- 21%.
