以200g/L氯虫苯甲酰胺SC和50%杀螟丹WP为对照药剂,进行140g/L氯虫·高氯氟CS防治甘蔗螟虫田间药效试验。结果表明:140g/L氯虫.高氯氟CS对甘蔗螟虫有良好的防效,其中3000倍液防效最高、速效性最好、持效期最长,药后7～35d防效达82.58%以上,明显高于200g/L氯虫苯甲酰胺SC和50%杀螟丹WP;其次是4500倍液,药后7～35d,防效为79.46%以上,且对甘蔗安全,值得推广应用。
The efficacy of 140g / L chlorantraniliprole and high chlorofluorocarbon (CS) to control sugarcane borer was tested with 200g / L Chlorantranilon SC and 50% Cartap WP as control. The results showed that: 140g / L Chlorsulfuron and Chlorfluosulfuron CS had good control effect on sugarcane borer, of which 3000 times had the highest control effect, the best quick-acting effect and the longest persistence period, and the control effect was 82.58 %, Significantly higher than 200g / L chlorantraniliprole SC and 50% Cartap WP; followed by 4500 times, 7 ~ 35d after the drug, the control effect of 79.46% or more, and the safety of sugarcane, it is worth to promote the use of .
