摘要
田间药效试验结果表明:施用30%吡蚜·异丙威WP 450～600 g/hm2,药后1～14 d对草莓蚜虫的防治效果达79.96%～95.17%, 显著高于30%吡蚜·异丙威WP 300 g/hm2的防治效果(76.22%～87.70%)和对照药剂10%吡虫啉600 g/hm2的防治效果(62.58%～83.67%).在田间施用30%吡蚜·异丙威WP 450 ～ 600 g/hm2,对草莓生长安全.
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.
