Application of 2% SP003 with Different Rate to Control Sugarcane Borer and Its Effect on Cane Yield and Sucrose Content
摘要
Abstract
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/hm2 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/hm2 higher than that of treatment with 3% carbofuran.④The application rate of 2% SP003 was recommended as 75 kg/hm2 which was supposed to be the most effective to control sugarcane borer and to increase cane and sugar yield and income.关键词
