The control effect on diamondback moth and diamondback insect is still 90-95% 14 days after the treatment, and the control effect can reach over 95%.

(2) The control effect of 1.8% abamectin emulsion (3000-5000 times) and 1000 times high chlorine spray (1000 times) on the egg hatching and larval development of the insect pests, such as Leaf-minder, Leaf-minder, Leaf-minder, Leaf-minder and whitefly, can reach more than 90% in 7-10 days after treatment.

(3) The control effect of 1.8% abamectin emulsion with 1000 times of abamectin can reach more than 90% in 7-10 days after treatment.

       Abamectin was first developed by Tomoya Omura from Kitasawa University in Japan and Merck Company in the United States. It is a kind of 16-yuan-macrolide compound with insecticidal, acaricidal and nematocidal activities. It is produced by the fermentation of Streptomycesavermitilis from Streptomyces greys.The natural abamectin contains 8 components, and there are mainly 4 kinds, namely A1A, A2a, B1A and B2a, with the total content ≥80%.The corresponding four homologues with a small proportion are A1b, A2b, B1b and B2B, and their total content is less than 20%.At present, abamectin is the main insecticidal component (avermectinB1a +B1b, of which B1a is not less than 90% and B1b is not more than 5%) in the market for abamectin pesticide, and the content of B1a is used for calibration .
