Embodiment 1
[0059] Example 1: 2% pyrimethanil · efficient cyhalothrin EC (1:1)
[0060] Pyrimimethan 1%, lambda-cyhalothrin 1%, emulsifier T-60 3%, Nongru 2201 3%, acetone 25%, ethyl acetate 10%, biodiesel to 100%. The above raw materials are conventionally prepared into EC, and after mixing, stirring and dissolving completely, 2% pyrimidan·beta-cyhalothrin EC is prepared.
Embodiment 2
[0061] Example 2: 10% Pyrimimethan · Beta-cyfluthrin EC (2:3)
[0062] Pyrimimethan 4%, Beta-cyfluthrin 6%, Nongru 500# 4%, Nongru 400# 3%, Nongru 1601# 5%, Epichlorohydrin 1%, Ethyl acetate 10%, Acetone 10%, Toluene made up to 100%. The above raw materials are prepared according to the conventional method of EC, and after mixing, stirring and dissolving completely, 10% pyrimidan·beta-cyfluthrin EC is prepared.
Embodiment 3
[0063] Example 3: 30% Pyrimimethan·Efficacyhalothrin SC (5:1)
[0064] Pyrimimethan 25%, lambda-cyhalothrin 5%, methyl naphthalenesulfonate condensate 2%, xanthan gum 0.2%, magnesium aluminum silicate 1%, ethylene glycol 5%, sodium benzoate 0.3%, organic Silicon defoamer 0.5%, water to make up to 100%. The above raw materials are conventionally prepared into a suspending agent, mixed, dispersed by high-speed shearing, and sand-milled to obtain a 30% pyrimethanil·beta-cyhalothrin suspending agent.

Abstract
The invention belongs to the field of pesticides, and discloses a composition for killing inspects and mites. The composition comprises two active components, namely an active component A and an active component B; the active component A is pyriminostrobin, the active component B is pyrethroid pesticide, and the weight ratio of the active component A to the active component B is 1:99 to 99:1. The composition has a prominent synergetic effect, and is used to control multiple kinds of harmful insects and mites.
Description
technical field [0001] The invention belongs to the field of pesticides, and relates to a synergistic compound composition containing two active components, in particular to a composition containing pyrethroid insecticides and an application thereof. Background technique [0002] In the actual process of agricultural production, the application of chemical agents is one of the most effective means of controlling plant diseases and insect pests. However, the most likely problem caused by chemical control of pests is the generation of resistance of pests and pest mites. At the same time, long-term continuous high-dose application of single chemical insecticides and acaricides is likely to cause a series of problems such as drug residues and environmental pollution. Reasonable compounding or mixing of chemical insecticides and acaricides can expand the insecticidal and acaricidal spectrum, improve the control effect, prolong the application period, reduce the dosage, reduce the...
