Embodiment 1

[0021] According to emamectin benzoate 0.5%, chlorfenapyr 10%, emulsifier 1601 8%, emulsifier 500# 5%, the balance is ethanol and xylene, and is formulated into an emulsifiable concentrate. Preparation method: Dissolve emamectin benzoate technical 0.5%, chlorfenapyr technical 10%, emulsifier 1601 8%, emulsifier 500#5% in ethanol and xylene, mix Mix well in the device, filter and pass the inspection and enter the automatic packaging machine, and the required emulsifiable concentrate can be obtained after measuring and packaging.

[0022] Using 25-50 g / mu of the mixed agent to spray evenly with water in the emergence stage of diamondback moth, the control effect is 95.50% one day after spraying, and more than 99% after 7 days.

Embodiment 2

[0024] Emamectin benzoate 0.5%, chlorfenapyr 5%, emulsifier 602 8%, emulsifier NP-10 5%, cyclohexanone 5%, xylene 5%, the balance is deionized water, formulated as a microemulsion. Preparation method: Emamectin benzoate technical 0.5%, chlorfenapyr technical 5%, emulsifier 602 8%, emulsifier NP-10 5%, cyclohexanone 5%, xylene 5% After fully dissolving in the mixing device, make up deionized water, enter the mixing tank and mix evenly, and then enter the automatic packaging machine after passing the inspection, and obtain the required microemulsion after measuring and packaging.

[0025] Using 30-50 g / mu of the mixed agent to spray evenly with water in the occurrence stage of diamondback moth, the control effect is 93.55% one day after spraying, and the control effect reaches more than 98% 7 days after spraying.

Embodiment 3

[0027] Prepare wettable powder with emamectin benzoate 5%, chlorfenapyr 5%, wetting agent pull-off powder 3%, dispersant NNO 8%, talcum powder 5%, and the balance is kaolin . Preparation method: Emamectin benzoate 5%, chlorfenapyr 5%, wetting agent pull-off powder 3%, dispersant NNO 8%, talcum powder 5%, and the balance is kaolin , After crushed by a coarse pulverizer, it enters a jet mill for complete pulverization and mixing, and after passing the inspection, it enters an automatic packaging machine, and the required wettable powder can be obtained after metering and packaging.

[0028] Using 10-20 g / mu of the mixed agent to spray evenly with water in the emergence stage of diamondback moth, the control effect is 91.37% one day after spraying, and the control effect reaches more than 98% 7 days after spraying.

Abstract

The invention relates to an insecticidal component with the active compounds of Emamectin Benzoate and Chlorfenapyr with the mass proportions of between 1:20 and 20:1, which is composed of Emamectin Benzoate and Chlorfenapyr. The insecticidal component is used for controlling resistant pests agriculturally, in particular for controlling resistant diamond back moth, and has the characteristics of high control efficiency, long effect lasting and safety.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to an insecticidal composition with emamectin benzoate and chlorfenapyr as active ingredients. Background technique [0002] Emamectin benzoate (emamectin benzoate) is a new type of high-efficiency semi-synthetic antibiotic insecticide synthesized from the fermentation product avermectin B1. It has ultra-high efficiency, low toxicity, no residue, no The characteristics of biological pesticides such as public nuisance are extremely active in preventing and controlling the larvae of Lepidoptera insects and many other pests and mites, and have both stomach poisoning and contact killing effects. [0003] Chlorfenapyr (chlorfenapyr) is a new type of pyrrole compound, which acts on the mitochondria of cells in insects, acts through the multifunctional oxidase in insects, and mainly inhibits the conversion of adenosine diphosphate (ADP) to adenosine triphosphate (ATP). With stomach poisoning and...
