摘　　要：为了评估不同药剂、相同药剂用不同剂量对稻纵卷叶螟的防治效果,设置了6个处理进行试验。结果显示:26%甲氧·茚虫威SC用量20 g/667 m^(2)和40%氰氟虫腙·甲氧虫酰肼SC用量40 mL/667 m^(2)对稻纵卷叶螟的防治效果最好,能够有效地控制害虫数量,保护水稻的生长。具体情况为,在用药后的第7天,处理3的杀虫效果为97.09%,保苗效果为69.14%,处理5的杀虫效果为83.50%,保苗效果为63.67%;在用药后的第14天,处理3和处理5的杀虫效果分别为91.47%和95.90%,保苗效果分别为91.29%和89.66%。In order to evaluate the control effect of different agents and different doses of the same agent on Cnaphalocrocis medinalis,6 treatments were set up.The results showed that 26%methoxyinacarb SC dosage of 20 g/667 m^(2) and 40%fenflurazone methoxyfenazide SC dosage of 40 mL/667 m^(2) had the best effect on the control of Cnaphalocrocis medinalis,which could effectively control the number of pests and protect the growth of rice.The specific situation is that on the 7th day after administration,the insecticidal effect of treatment 3 is 97.09%,the seedling preservation effect is 69.14%,the insecticidal effect of treatment 5 is 83.50%,the seedling preservation effect is 63.67%.On the 14th day after administration,the insecticidal effect of treatment 3 and treatment 5 was 91.47%and 95.90%,and the seedling preservation effect was 91.29%and 89.66%,respectively.
