为筛选防治甘蔗螟虫、白蚁的有效药剂,分别在不同蔗区,选择不同甘蔗品种及不同栽培制度进行田间药效筛选试验。结果表明,3月中旬结合甘蔗下种或施苗肥一起施用,5%异丙特丁硫磷GR 75 kg/hm2和3.6%杀虫双GR 90 kg/hm2对甘蔗螟虫、白蚁有较好的防治效果,5%二嗪磷GR 75 kg/hm2和8%毒.辛GR 75 kg/hm2对甘蔗白蚁有较好的防治效果,防效均达70%以上,且对甘蔗安全。在甘蔗螟虫、白蚁的防治中,可结合生产实际选择施用,剂量以75～90 kg/hm2为宜。
In order to screen effective pesticides for control of sugar cane borers and termites, different sugar cane varieties, different sugarcane varieties and different cultivation systems were selected for field efficacy test in different sugarcane fields. The results showed that 5% iputonosil GR 75 kg / hm2 and 3.6% pest control GR 90 kg / hm2 were suitable for sugarcane borers and termites The control effect of 5% diazinon GR 75 kg / hm2 and 8% poison syphilis GR 75 kg / hm2 on sugarcane termite has better control effect, the control effect is over 70%, and the safety of sugarcane. In the control of sugarcane borers and termites, it can be combined with the actual choice of production, and the dosage is preferably 75-90 kg / hm2.
