摘要
针对甘蔗螟虫难防难治的特点,结合康宽防治鳞翅目害虫有特效的实际,开展了不同浓度的康宽防治甘蔗螟虫试验。结果表明:康宽(20%氯虫苯甲酰胺悬浮剂)对甘蔗螟虫具有良好的防治效果,田间苗期喷施康宽(20%氯虫苯甲酰胺悬浮剂)300mL/hm2+80%锐劲特水分散粒剂30g/hm2效果最好;从生产成本分析,苗期喷施康宽(20%氯虫苯甲酰胺悬浮剂)150mL/hm2最经济。
It was difficult to prevent the lepidoptera pests in sugarcane,combined with the fact that Dupon Coragen had special effects in preventing the lepidoptera pests of sugarcane and the controlling effect experiment that Dupon Coragen of different concentrations was carried out. The results showed that：Dupon Coragen had good effects on controlling the lepidoptera pests in sugarcane,controlling effects were the best at Dupon Coragen 300 mL/hm2 adding 8% Regent 30 g/hm2 consideting the production cost,controlling effects were the most economical at Dupon Coragen 150 mL/hm2 in seedling.
