Embodiment 1

[0074] The present invention contains the emulsifiable concentrate preparation of the high-efficiency insecticide of bifenthrin, flubendiamide, dinotefuran and spinocidin, and the specific composition is as follows (1000g per part):

[0075] Bifenthrin: 15 parts; flubendiamide: 15 parts; dinotefuran: 25 parts; spinosad: 25 parts.

[0076] The specific production steps of the emulsifiable concentrate preparation are as follows: the active ingredients bifenthrin, flubendiamide, dinotefuran, and spinosad are completely dissolved in the solvent according to the conventional procedures in the field, and then the emulsifier and synergist are added. Stir evenly to form a uniform transparent oily liquid, fill it, and then the emulsifiable concentrate preparation of the composition of the present invention can be made.

Embodiment 2

[0078] The present invention contains the suspending agent of bifenthrin, flubendiamide, dinotefuran and spinocidin high-efficiency insecticide, and the specific composition is as follows (1000g per part):

[0079] Bifenthrin: 35 parts; flubendiamide: 45 parts; dinotefuran: 35 parts; spinosad: 35 parts.

[0080] The specific production steps of this suspending agent are the conventional suspending agent preparation method in the art, first other auxiliary agents (dispersant, antifreeze agent, thickener, defoamer, penetration enhancer and pH value regulator) are mixed, Shear and mix evenly, add the active ingredients bifenthrin, flubendiamide, dinotefuran and spinosad, and grind the balls in a ball mill for 2 to 4 hours, so that the particle diameter is less than 5mm. Suspension formulations of the compositions of the invention are prepared.

Embodiment 3

[0082] The present invention contains the water dispersible granules of bifenthrin, flubendiamide, dinotefuran and spinosad high-efficiency insecticide, and the specific composition is as follows (1000g per part):

[0083] Bifenthrin: 25 parts; Flubendiamide: 30 parts; Dinotefuran: 30 parts; Spinosyn: 30 parts.

[0084] The specific production steps of the water-dispersible granules are the conventional preparation methods of water-dispersible granules in the art: according to the above formula, the active ingredients bifenthrin, flubendiamide, dinotefuran, spinetoram dispersant, The wetting agent, disintegrating agent and filler are mixed evenly, pulverized with an ultra-fine jet mill, kneaded, and then added to a fluidized bed granulation dryer for granulation, drying, sieving, and sampling and analysis. Water-dispersible granules of the compositions of the present invention.

Abstract

The invention relates a high-efficiency pesticide composition used for killing agricultural pests. The high-efficiency pesticide composition is composed of the components of, by weigh, 10-40 parts of bifenthrin, 10-50 parts of flubendiamide, 20-40 parts of dinotefuran and 20-40 parts of spinetoram. The pesticide composition provided by the invention has a significant synergistic effect, such that a pesticidal spectrum is broad, effective component doses can be effectively reduced, and application cost can be reduced; with the pesticide, pest drug resistance can be retarded, and environmental pollution and pesticide residue can be effectively reduced. The pesticide causes no phytotoxicity, and has low toxicity and no chronic toxicity to human and mammals. The pesticide has significant effects against paddy rice stem borers and leaf rollers, and homoptera piercing-sucking mouthpart pests which are mainly plant hoppers, aphids and mites.

Description

technical field [0001] The invention relates to the field of insecticides used for the control of agricultural pests, in particular to a high-efficiency insecticide containing bifenthrin, flubendiamide, dinotefuran and spinosad. Background technique [0002] The residues of pesticides in agricultural products and the toxicity to animals have always been a hot spot of concern. [0003] Bifenthrin: [0004] Chinese aliases: Tiannuxing, Chongmiteling, Bifenning [0005] English name: Bifenthrin [0006] Molecular formula: C 46 h 44 C l2 f 6 o 4 [0007] Molecular weight: 845.7356 [0008] Structural formula: [0009] [0010] Bifenthrin is highly toxic to fish, the LC50 (96 hours) for rainbow trout is 0.00015mg / L, and the LC50 (48 hours) for Daphnia is 0.00016mg / L. However, because the agent has a high affinity in the soil and its water solubility is low, the actual impact is relatively small. This agent is moderately toxic to bees and highly toxic to silkworms. ...
