Problems solved by technology

According to statistics, in the Yellow River Basin and the Yangtze River Basin in my country, the loss caused by the green Lygus is as high as 20-30% in normal years, and more than 50% in severe years. In order to actively deal with the outbreak of the green Lygus, it is urgent to develop effective control agents, but , foreign studies have shown that mirid bugs have developed resistance to a variety of insecticides, so mixing insecticides is an effective means to delay pest resistance

Embodiment 1

[0019] A compound pesticide for preventing and treating Lygus japonica, the raw materials of which are composed of 5% phoxim, 20% malathion, 8% azone, 10% emulsifier, and the balance of solvent in terms of weight percentage.

[0020] Its preparation method is as follows: take the raw materials of the above ratio, dissolve phoxim and malathion in a solvent respectively, and mix them uniformly; then add azone and emulsifier in sequence, add the remaining amount of solvent, and stir until uniform and transparent. solution.

[0021] The emulsifier described in this example is pesticide emulsifier 0201, and the solvent is acetone.

[0022] The compound pesticides prepared above were used for the control of Lygus lucidum with reference to NY / T 1154.8-2007, and the mortality rate reached 93.3%.

Abstract

The invention belongs to the technical field of compound pesticides, and in particular relates to a compound pesticide for controlling apolygus lucorum and a preparation method of the compound pesticide. According to the preparation method, phoxim and malathion are taken as active ingredients to prepare the compound pesticide, the advantages of the phoxim and the malathion are complemented with each other, not only are the characteristics of good control effect and strong knockdown capacity of the phoxim brought into play, but also the defects of quick photodecomposition and short duration of the phoxim are overcome, the pesticide effect is obviously improved, and the synergistic effect is obvious; and the compound pesticide has an obvious effect on controlling the apolygus lucorum, and the use cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, and in particular relates to a compound pesticide for preventing and treating Lygus lucidum and a preparation method thereof. Background technique [0002] The green Lygus, scientific name Apolygus lucorum (Meyer—Dür), belongs to the order Hemiptera, Miridae, and the genus Lygus. With the adjustment of the agricultural industry structure, the substantial increase in the planting area of ​​fruit trees and vegetables has provided abundant host plants and suitable places for overwintering for the green Lygus bug. The green Lygus has become the main pest in my country's cotton fields. [0003] The adults and nymphs of the green Lygus gnaw and suck the juice on the top buds, young leaves, flower buds and young bolls of the cotton plant, and the young buds are damaged to form "male" cotton with only two plump cotyledons left; the leaves are damaged to form a large number of holes and shrinka...
