本文就SP003(新烟碱类)在使用剂量与防治效果、与几种常用药剂之间的比较以及持效期等方面进行了防治甘蔗螟虫的试验研究。结果显示:SP003使用剂量与防治效果之间存在正相关,即防治效果随使用剂量的增加而提高,处理剂量ai 600 g/hm2、900 g/hm2和1200 g/hm2的防治效果分别达到69.06%～71.83%、76.21%～83.23%和83.35%～84.07%。与常用药剂的防治效果相比,SP003显著优于辛硫磷和毒死蜱等2种低毒有机磷类杀虫剂;优于或相当于高毒有机磷类杀虫剂特丁硫磷;显著优于高毒氨基甲酸酯类杀虫剂呋喃丹。
In this paper, SP003 (neonicotinoid) in the use of dose and control effect, with several commonly used drugs between the comparison and the duration of control of sugar cane stem borer research. The results showed that there was a positive correlation between the dose of SP003 and the control effect, that is, the control effect increased with the increase of the dosage. The control effects of 600g / hm2, 900g / hm2 and 1200g / hm2 were 69.06% ~ 71.83%, 76.21% ~ 83.23% and 83.35% ~ 84.07% respectively. Compared with the control effect of the commonly used agents, SP003 was significantly better than the two kinds of low toxicity organophosphate insecticides such as phoxim and chlorpyrifos; better than or equivalent to the high toxic organophosphate insecticide, In the highly toxic carbamate insecticide carbofuran.
