| 摘 要： | 应用2.5%功夫乳油、2.5%功夫水乳剂和0.5%苦参碱水剂3种杀虫剂进行翠冠梨套袋前喷药对梨果无锈果率影响的试验表明,喷施2.5%功夫乳油杀虫剂的果品无锈果率最低,仅为21.6 %;喷施2.5%功夫水乳剂的无锈果率则较高,达83%以上,且杀虫效果也达到91%以上;喷施0.5%苦参碱水剂的无锈果率也达85%以上,但杀虫效果只有71.85%.建议生产中使用1 500倍液2.5%功夫水乳剂进行套袋前喷药. |
| 关 键 词： | 翠冠梨 锈果率 功夫水乳剂 农药防治 |

| Abstract: | Experiment of effect of 2.5% Lambda-cyhalothrin emulsifiable concentrate, 2.5% Lambda-cyhalothrin and 0.5% Matrine before fruit bag casing on rust spot rate resulted that application of 2.5% Lambda-cyhalothrin emulsifiable concentrate had the highest rust spot rate, with 78.44%, while that of 2.5% Lambda-cyhalothrin had lower one, with 17%, and 91% insecticidal effect, that 0.5% Matrine had 15% rust spot rate, but 71.85% insecticidal effect. Suggestion was offered to apply 1 500-fold 2.5% Lambda-cyhalothrin before bag casing. |
| Keywords: | Cuiguan Pear rust spot rate Lambda-cyhalothrin chemical control |
