| 摘 要： | 温室试验结果表明:10％浏阳霉素乳油防治辣椒多食跗线螨效果显著。其4000倍稀释液三周内保持螨口减退98％以上,与三氯杀螨醇的效果相仿;喷药5天后接上多食跗线螨雌成螨和幼若螨,仍有较大的杀伤作用,其触杀残效分别为71.1％和83％,但7天后作用明显减弱。在为期8个月的温室单茬辣椒上分别施用浏阳霉素和三氯杀螨醇各3次,均能有效控制多食跗线螨在为害水平之下。10％浏阳霉素500倍以上稀释液未发现对辣椒有药害。

| Abstract: | Results of greenhouse tests conducted during May, 1989 in Beijing showed that 25 ppm Liuyangmycin (diluted 4000 times) gave the most effective and economical control of the yellow mite in comparison with other 3 concentrations tested (i.e. 50 ppm, 16.7 ppm, 12.5 ppm). The control effect in the first three weeks remained above 98%, which was equivalent to that with 200 ppm Dicofol. Introduction of female adults or nymphs of the mite on green pepper plants 5 days after an application of Liuyangmycin on the plants resulted in 71.1% and 83% mortalities, respectively. The residual effect declined obviously after 7 days. Applying 25 ppm Liuyangmycin three times on the pepper in the greenhouse during September to the next April gave a satisfactory control of the mite populations with no harmful side-effect found to the pepper. This control effect was similar to that with three applications of Dicofol. |
