摘　　要：通过对新烟碱类杀虫剂2%SP003不同施药剂量防治甘蔗螟虫试验结果分析表明:12%SP003对甘蔗螟虫防治效果良好,杀虫活性高,持效期较长,其枯心率比3%呋喃丹低1.34%~2.66%、虫害节率比3%呋喃丹低1.56%~4.97%,差异均达极显著。其防治效果比呋喃丹提高11.80%~23.76%;2对甘蔗蓟马、蚜虫等有较好的兼防治效果;3促进甘蔗生长,有效茎较多、植株较高、茎径较粗、糖分高,达到增产、增收效果。其蔗茎产量比3%呋喃丹增产1275~7785 kg/hm^2,甘蔗糖分比施3%呋喃丹处理提高0.15%~0.35%(绝对值),农业增加收益比3%呋喃丹多510~4434.0元/hm^2;4综合分析,2%SP003施用量以75 kg/hm^2防治螟虫效果较好,效益高。The field effect test of 2% SP003 with different application rate to control sugarcane borer was carried out. The results were summarized in this paper. 12% SP003 was effective to control sugarcane borers. The rate of dead-heart of treatments with 2% SP003 was 1.34%~2.66% lower than that of the treatment with 3% carbofuran. The rate of infested-nodes of treatments with 2% SP003 was 1.56%~4.97% lower than that of treatment with 3% carbofuran. All the difference was very significant. The control effect of 2% SP003 was 11.80%~23.76% higher than that of 3% carbofuran. 2Sugarcane thrips and aphids could be also controlled simultaneously by 2% SP003. 3Sugarcane growth was improved, with more millable cane stalk, higher stalk length and diameter when treated with 2% SP003, resulting higher cane yield and economic effect. The cane yield of treatments with 2% SP003 was 1275~7785 kg/hm^2 higher than that of treatment with 3% carbofuran, the sucrose of treatments with 2% SP003 was 0.15%~0.35% higher than that of treatment with 3% carbofuran, and the agricultural income of treatments with 2% SP003 was 510~4434.0 yuan/hm^2 higher than that of treatment with 3% carbofuran. 4The application rate of 2% SP003 was recommended as 75 kg/hm^2 which was supposed to be the most effective to control sugarcane borer and to increase cane and sugar yield and income.
