Embodiment 1

[0030] Example 1: 33% Fenpyran-Ivermectin Suspension Concentrate (32.5:0.5)

[0031] Pump 468 grams of deionized water into the stirring tank, pump 68 grams of SOPA270, 36 grams of K12, 5 grams of formaldehyde, and 68 grams of pentylene glycol [1,5] into the stirring tank, and then stir 325 grams of tonfenpyrad , 5 gram ivermectin, 3 gram sodium benzoate, 22 gram white carbon black, drop in the shear tank according to order, shear 30 minutes and make material mix homogeneously. Turn on the circulating water, ball mill the material with a certain amount of flow, control the temperature below 40 degrees, and pass the fineness through a 325 mesh sieve to obtain a 33% tonamiprole-ivermectin insecticide composition suspension.

Embodiment 2

[0032]Example 2: 42% tonamiprole·ivermectin water dispersible granules (2:40)

[0033] With 20 grams of pyrenpyran, 400 grams of ivermectin, 10 grams of triethanolamine, 185 grams of white carbon black, 92 grams of MF, 46 grams of starch, 154 grams of kaolin, and 93 grams of ammonium sulfate, mix them uniformly and grind them into airflow, and mix them In the machine, spray about 200 grams of kneading agent deionized water, adjust the extrusion equipment, carry out extrusion granulation, and dry at 50-80°C until the moisture is qualified, and then 42% tonfenpyrad·Evi Water-dispersible granules of mycocin insecticide composition.

Embodiment 3

[0034] Example 3: 78% Fenpyran-Ivermectin WP (50:28)

[0035] With 500 grams of pyrenpyramide, 280 grams of ivermectin, 54 grams of sodium lignosulfonate, 32 grams of alkylphenol (or fatty alcohol) polyoxyethylene polyoxypropylene ether sulfate, 2-methylpentanediol [ 2, 4] 30 grams, 78 grams of white carbon black, 26 grams of kaolin, stirred evenly, processed by airflow milling method, can get 78% wettable powder of insecticide insecticide composition of fenpyradram·ivermectin.

Abstract

The invention discloses an insecticidal composition containing tolfenpyrad and ivermectin, which comprises the following active ingredients, namely, tolfenpyrad and ivermectin, wherein the weight ratio of the tolfenpyrad to the ivermectin is 1: 65-65: 1, and the cumulant of the tolfenpyrad and the ivermectin is 0.5-78 percent of the weight of the insecticidal composition; and the insecticidal composition can be prepared into agriculturally allowable suspending agent, water dispersible granules, wettable powder, micro-capsule suspending agent, missible oil, emulsion in water or microemulsion or other dosage forms. The insecticidal composition has reasonable components, good insecticidal effect and low medication cost; in addition, the activity and the insecticidal effect of the insecticidal composition are not simple overlaying of the activities of various components; and compared with the traditional single preparation, the insecticidal composition has the advantages of remarkable insecticidal effect and synergistic effect, capability of retarding generation of resistance, less preparation residues, no pollution to crops, good safety, accordance with safety requirements of pesticide preparations and better control effects on rice steam borers, vegetable diamond back moths, beet armyworms, thrips, cotton bollworms, aphids and other insect pests.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to an insecticidal composition containing tolfenpyrad and ivermectin. Background technique [0002] Tolfenpyrad, common name in English: Tolfenpyrad, 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, Coleoptera and other pests. When the dose is applied, the agent has the repelli...
