| Abstract: | The efficacies of 8 pesticides against nymph and egg of pear psylla (Psylla chinensis) were tested in the field experiment in which 8 treatments were included. The result indicates that efficacies against nymph with buprofezin 2000×, Tesha 1500×, 10% imidacloprid wp 1500×+omephoate 800×, Mospilan Ec 1500× and julisha 1000× are all 100% 3days after spraying. The residual effects of buprofezin 2000× and Tesha 1500× Were still as high as 100% 14 days after spraying. Excepting Guoshuli, all other treatments of the tested pesticides to control egg possessed excellent efficiencies which are over 90% 14days after spraying. |
