Problems solved by technology

[0014] The purpose of the present invention is to provide a kind of insecticidal composition containing pyrenpyramid in order to overcome the shortcomings of the above-mentioned single insecticides, such as the large amount of use, serious environmental pollution, etc., and the problems of each single-dose composition. Under the optimal ratio, it has the synergistic effect of the formula, which not only expands the application range of each single agent, but also reduces the amount of chemicals used and the amount of mu used while ensuring the optimal control effect, thereby reducing costs and reducing environmental hazards, and can delay pest resistance. sexual production

Embodiment 1

[0040] 20% Fenpyran·Chlorantraniliprole SC (16:4)

[0041] Pump 639 grams of deionized water into the mixing tank, pump 50 grams of SOPA270, 28 grams of K12, 4 grams of formaldehyde, and 62 grams of pentylene glycol [1,5] into the mixing tank, and then stir 160 grams of tonfenpyrad, Put 40 grams of chlorantraniliprole and 15 grams of white carbon black into the shear tank in sequence, and shear for 30 minutes to mix the materials evenly. Turn on the circulating water, ball mill the material at a certain flow rate, control the temperature below 40 degrees, and pass the fineness through a 325 mesh sieve to obtain a 20% suspending agent of the insecticide composition of chlorantraniliprole and chlorantraniliprole.

Embodiment 2

[0043] 70% Fenpyran·Chlorantraniliprole Water Dispersible Granules (35:35)

[0044] 350 grams of pyrenpyramid, 350 grams of chlorantraniliprole, 6 grams of triethanolamine, 12 grams of white carbon black, 20 grams of NN0 (sodium dinaphthyl methane disulfonate), 45 grams of wetting penetrant MF, 8 grams of starch, 150 grams of kaolin, 59 grams of ammonium sulfate, after mixing evenly, enter the airflow and pulverize. In the mixer, spray about 200 grams of kneading agent deionized water, adjust the extrusion equipment, carry out extrusion granulation, and bake at 50-80 ° C. After drying until the water content is qualified, a 70% water-dispersible granule of the insecticide insecticide composition of tonfenpyrad and chlorantraniliprole can be prepared.

Embodiment 3

[0046] 35% Fenpyran·Chlorantraniliprole WP (31:4)

[0047] Fenpyran 310 grams, chlorantraniliprole 40 grams, sodium lignosulfonate 55 grams, alkylphenol (or fatty alcohol) polyoxyethylene polyoxypropylene ether sulfate 38 grams, 2-methylpentanediol [2,4] 35 grams, 95 grams of white carbon black, 427 grams of kaolin, stir evenly, and process it by jet milling method to get 35% tonamiprole · chlorantraniliprole wettable powder.

Abstract

The invention discloses a tolfenpyrad-containing insecticidal composition. The effective components include tolfenpyrad as a first active component, and chlorantraniliprole or dimethacarb as a second active component; the weight ratio of the first active component to the second active component is 1:70 to 70:1; the weight sum of the first active component and the second active component accounts for 1-70% of the total weight of an agricultural compound composition; and the tolfenpyrad-containing insecticidal composition can be prepared into a normal formulation such as suspension, water dispersible granules, wettable powders, microcapsule suspension, emulsifiable concentrate, water emulsion, microemulsion or the like. The composition is used for preventing and treating diseases caused by diamondback moth larvae in Lepidoptera, thrips in Thysanoptera, rice stem borers, leaf folders, cotton bollworms and the like. The composition has the advantages of high efficacy, long durability, reduced environment pollution and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a pesticide composition, in particular to an insecticidal composition containing tolfenpyrad. Background technique [0002] Tolfenpyrad, English common name: Tolfenpyrad, chemical formula: C 21 h 22 ClN 2 o 2 , CAS: 129558-76-5, code name: OMI-88, chemical name: 4-chloro-3-ethyl-1-methyl-N-{[4-(4-methylphenoxy)phenyl] -Methyl}-1H pyrazole-5-carboxamide, relative molecular mass: 383.9, chemical structural formula: [0003] [0004] Fenpyran is a novel pyrazole heterocyclic insecticide and acaricide. Its mechanism of action is to hinder the electron transfer system complex I in the mitochondrial metabolic system, thereby hindering the electron transfer and preventing insects from providing and storing energy. It is called the mitochondrial electron transfer complex inhibitor (METI). The agent has a wide insecticidal spectrum and has contact killing effect. It has special...
