Embodiment 1

[0073] Example 1: 31% Chlorfluazuron·Imidacloprid Suspension Concentrate (1:30)

[0074] Components: Chlorfluazuron 1%, Imidacloprid 30%, Alkylphenol Polyoxyethylene Phosphate 4%, Polyoxyethylene Polyoxypropylene Ether Block Copolymer 3%, Ethylene Glycol 5%, Xanthan Gum 0.15 %, silicone defoamer 0.1%, Kasone 0.5%, water to make up to 100%.

[0075] Preparation method: Mix the components, mix them uniformly by high-speed shearing, and then grind them with a sand mill for 2-3 hours, so that the average particle size reaches 1-5 microns, and then you can prepare 31% dichlorfluazuron imidacloprid suspension agent.

Embodiment 2

[0079] Example 2: 26% Chlorfluazuron·Imidacloprid Water Dispersible Granules (1:25)

[0080] Chlorfluazuron 1%, imidacloprid 25%, sodium lauryl sulfate 1%, sodium lignosulfonate 6%, starch 5%, kaolin supplement 100%.

[0081] Preparation method: Mix the original drug, additives and fillers uniformly, then perform jet crushing, wet granulation and drying to obtain 26% chlorfluazuron·imidacloprid water-dispersible granules.

Embodiment 3

[0082] Example 3: 42% Chlorfluazuron · Imidacloprid WP (1:20)

[0083] Chlorfluazuron 2%, imidacloprid 40%, sodium lauryl sulfate 1%, sodium lignosulfonate 6%, kaolin supplement 100%.

[0084] Preparation method: After mixing the original drug, additives and fillers uniformly, they are crushed by airflow to obtain 42% hexazuron · imidacloprid wettable powder.

Abstract

The invention discloses an insecticidal composition and an application thereof, and relates to the technical field of insecticide compounding. The insecticidal composition includes an effective component A and an effective component B. The effective component A is chlorfluazuron, and the effective component B is one or more of anabasine insecticides. A weight ratio of the effective component A to the effective component is 1:30-40:1, and preferably 1:20-20:1. The obtained compounded agent has reasonable proportioning and substantial synergy effects, has excellent effects on phloem sucking pests, lepidoptera pests and agricultural mites, such aphids, rice hopper, rice stem borer, carminespider mites and two-spotted spider mites, can effectively reduce the application amount of single doses to delay the drug resistance and reduce the cost, and has obvious application and popularization values.

Description

technical field [0001] The invention relates to an insecticidal composition and its application, in particular to an insecticidal composition containing chlorfluazuron and neonicotinoid insecticides as active ingredients and its application, and belongs to the technical field of pesticide compounding. Background technique [0002] In the actual process of agricultural production, chemical control is still the most effective means of controlling pests, but due to the continuous and large-scale use of chemical insecticides, the problem of pest resistance has become increasingly prominent. Moreover, the pests that are prone to resistance to pesticides are usually those with large reproduction numbers and obvious overlapping generations. Such as planthoppers, aphids, spider mites, diamondback moths, etc. [0003] Wheat aphid is the largest pest in the process of wheat planting. Because of its large occurrence, difficult to kill, and easy to develop resistance, commonly used ins...
