Embodiment 1

[0087] 32.8% Fenpyran·Spirofen SC (0.8:32)

[0088] Pump 466 grams of deionized water into the mixing tank, pump 68 grams of SOPA270, 34 grams of K12, 5 grams of formaldehyde, and 68 grams of pentanediol [1, 5] into the mixing tank, and then mix 8 grams of tonfenpyrad , 320 gram spirodiclofen, 3 gram sodium benzoate, 28 gram white carbon black, drop in the shear tank according to order, shear 30 minutes and make material mix 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 32.8% suspending agent of the insecticide composition of pyrenpyradrox.

Embodiment 2

[0090] 80% Fenpyramid Spirofen Water Dispersible Granules (40:40)

[0091] Mix 400 grams of pyrenpyradramide, 400 grams of spirodiclofen, 10 grams of triethanolamine, 165 grams of white carbon black, and 25 grams of ammonium sulfate. After mixing evenly, enter the air flow and pulverize it. In the mixer, spray about 126 grams of deionized water into the kneading agent , adjust the extrusion equipment, carry out extrusion granulation, and dry at 50-80 ° C until the water content is qualified, and then 80% water-dispersible granules of the insecticide insecticide composition of tonamiprole spirodiclofen can be obtained.

Embodiment 3

[0093] 31.5% Fenpyramid Spirofen WP (30:1.5)

[0094] 300 grams of pyrenpyramide, 15 grams of spirodiclofen, 58 grams of sodium lignosulfonate, 38 grams of alkylphenol (or fatty alcohol) polyoxyethylene polyoxypropylene ether sulfate, 2-methylpentanediol [2 , 4] 31 grams, 78 grams of white carbon black, 480 grams of kaolin, stirred evenly, and processed by airflow milling method to obtain 31.5% wettable powder of the insecticide composition of fenpyran and spirodiclofen.

Abstract

The invention discloses a pesticide composition containing Tolfenpyrad and Envidor. The pesticide composition comprises the effective ingredients of Tolfenpyrad and Envidor at a weight ratio of 1:65-65:1. The pesticide composition can be prepared into agriculturally allowable suspending agent, water-dispersed granules, wettable powder, microcapsule suspending agent, oil emulsion, aqueous emulsion or microemulsion and other dosage forms. The pesticide composition is reasonable in components, good in pest-killing effect and low in use cost; and the activity and pest-killing effect are not simple superpose of the activities of the components. Compared with the traditional single preparation, the pesticide composition has significant pest-killing effect and significant synergistic action, slows the resistance generation, is low in preparation residue, has no pollution to crop and good safety, and conforms to the safety requirement of the pesticide preparation. The composition can be used for prevention and control of multiple agricultural pests, and is particularly suitable for prevention and control of aleyrodids, scale insects, aphids, mites and other pests.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to an insecticidal composition containing tolfenpyrad and spirodiclofen. Background technique [0002] Fenpyramid, chemical name: 4-chloro-3-ethyl-1-methyl-N-{[4-(4-methylphenoxy)phenyl]-methyl}-1H pyrazole-5- Carboxamide, molecular formula: C21H22CIN2O2, structural formula: [0003] [0004] Fenpyran is a new type of pyrazole heterocyclic high-efficiency 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 drug is highly effective and quick-acting. The pests will die soon after their mouthparts are inserted into the crops treated with the drug. At the same time, the drug has a high antifeeding effect on Lepidoptera, Coleop...
