Embodiment Construction

[0021] Embodiment, chlorpyrifos 20kg and emamectin 0.5kg are dissolved in methanol 10kg, then drop into 0203B8kg, 0201B5kg, toluene 0.5kg and fully stir evenly, then drop into the homogenizer that dispersion medium water 61kg is housed to give intense Mix and homogenize to finally obtain 20% chlorpyrifos emamectin microemulsion. The aforementioned microemulsion was diluted 1000 times and sprayed. According to the method of Experimental Implementation 1, the control effect on beet armyworm was 85% 5 days after administration. Control beet armyworm with 1000 times liquid of microemulsion produced by the present invention

Abstract

The invention discloses an insecticidal composition microemulsion, mainly comprising chlorpyrifos 5-30%, Emamectin B1 Benzoate 0.1-3%, assisting solvent 5-20%, emulsifying agent 5-25% and water 20-70%. The invention provides a highly effective, low residual pesticide microemulsion, which has specially good effect for killing sugar beet moth and diagonal moth on the vegetable.

Description

technical field [0001] The invention relates to a pesticide, in particular to a chlorpyrifos emamectin microemulsion. Background technique [0002] Beet armyworm and Spodoptera litura: both belong to Lepidoptera, Noctuidae, distributed all over the world, generally occur in Africa, Europe, America and Asia, and occur in all provinces of my country, but more in southern provinces. Beet armyworm mainly feeds on cruciferous plants, but can also damage some other plants such as tomatoes, ginger, and potatoes. The beet armyworm damages the leaves with larvae. The first instar larvae can drill into the leaf tissue to feed on the mesophyll, and when they are slightly larger, they can eat the epidermis and mesophyll of the leaf to form a transparent spot. The 3rd to 4th instar larvae feed and cause holes and nicks. In severe cases, the vegetable leaves are eaten into a net, which reduces the edible value of the vegetable. In the seedling stage of vegetables, the center leaves are ...
