Embodiment 1

[0053] Example 1 10% dinotefuran bifenthrin wettable powder

[0054] The formula is: dinotefuran 5%, bifenthrin 5%, dispersant sodium alkyl polyoxyethylene ether sulfate 1.25%, naphthalenesulfonic acid formaldehyde condensate sodium salt 1.25%, wetting agent diisobutylnaphthalenesulfonic acid Sodium 1.5%, sodium lauryl sulfate 1.0%, anti-caking agent white carbon black 7%, filler kaolin 15%, anhydrous sodium sulfate added to 100%.

[0055] The preparation method is as follows: mix dinotefuran, bifenthrin, dispersant, wetting agent, anti-caking agent and filler in a mixer evenly, and pulverize it with a jet mill until the particle size is 20-30 μm, and then carry out secondary Mix and mix evenly to obtain dinotefuran bifenthrin wettable powder.

Embodiment 2

[0056] Example 2 30% dinotefuran bifenthrin wettable powder

[0057] The formula is: dinotefuran 20%, bifenthrin 10%, dispersant sodium alkyl polyoxyethylene ether sulfate 1.25%, naphthalenesulfonic acid formaldehyde condensate sodium salt 1.25%, wetting agent diisobutylnaphthalenesulfonic acid Sodium 1.25%, sodium lauryl sulfate 1.25%, anti-caking agent white carbon black 7%, filler kaolin 15%, anhydrous sodium sulfate added to 100%. The preparation method is the same as in Example 1.

Embodiment 3

[0058] Example 3 45% dinotefuran bifenthrin wettable powder

[0059] The formula is: dinotefuran 36%, bifenthrin 9%, dispersant sodium alkylpolyoxyethylene ether sulfate 1.5%, naphthalenesulfonic acid formaldehyde condensate sodium salt 1.0%, wetting agent diisobutylnaphthalenesulfonic acid Sodium 1.25%, sodium lauryl sulfate 1.25%, anti-caking agent white carbon black 7%, filler kaolin 15%, anhydrous sodium sulfate added to 100%. The preparation method is the same as in Example 1.

Abstract

The invention discloses an insecticidal composition of dinotefuran and bifenthrin and an application thereof. The active ingredients of the medicine are dinotefuran and bifenthrin, and the mass ratio of dinotefuran and bifenthrin is 1- 20:1. The active pharmaceutical ingredients dinotefuran and bifenthrin of the insecticidal composition of the present invention belong to two kinds of insecticides with different action mechanisms, and the mutual mixing of the two will not cause conflict, and the insecticidal spectrum is expanded, and the quick-acting effect is improved. And persistence, improve the insecticidal efficiency.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition containing dinotefuran and bifenthrin and the application of the composition in preventing and controlling insect pests of food crops, fruit trees and vegetables, and belongs to the technical field of pesticides. Background technique [0002] Bifenthrin is a high-efficiency synthetic pyrethrin insecticide and acaricide. It acts on sodium ion channels to interfere with the nervous system. It mainly acts as a contact and stomach poison. It has no systemic and fumigation effects, and its insecticidal effect is rapid. , Longer residual effect period, wide insecticidal spectrum, effective against various pests such as Lepidoptera, Hemiptera, Coleoptera, Thysanoptera, etc., also has certain control effect on Acarina pests, and can be used for both insects and mites. [0003] Dinotefuran is a neonicotinoid insecticide that selectively controls the nicotinic acet...
