Abstract

The results of field trial indicated that the control effect of 30% Pymetrozine·Isoprocarb WP at the dosage of 450~600 g/hm2 against strawberry aphids was 79.96%~95.17% from the 1st day to the 14th day after application,which was significantly higher than that of 30% Pymetrozine·Isoprocarb WP at the dosage of 300 g/hm2(76.22%~87.70%)and that of check insecticide 10% Imidacloprid at the dosage of 600 g/hm2(62.58%~83.67%).Spraying 30% Pymetrozine·Isoprocarb WP at the dosage of 450~600 g/hm2 was safe to strawberry growth in the field.
