Embodiment 180

[0068] Example 1 Efficacy test of 80% zhongdingwei·thiacloprid wettable powder in controlling rice leaf roller

[0069] 50% secbuterol, 30% thiacloprid, 5% lignosulfonate, 3% sodium lauryl sulfate, 2% saponin powder, 10% kaolin, and the mixture was air-milled to obtain 80% sec-butylene Wet thiacloprid wettable powder. The ratio is diluted and sprayed by 3000 times, and the effect of controlling rice leaf rollers is 95.14% to 96.87% 72 hours after the application. 300 times of use, the control effect after 72 hours was 80.77% and 76.41% respectively. In the experiment, the inventor did not find that the test medicament had adverse effects on crops and was safe for beneficial insects.

Embodiment 265

[0070] Example 2 Experiment on the efficacy of 65% isoprocarb·thiacloprid wettable powder in controlling rice planthopper

[0071] Isoprocarb 47%, thiacloprid 18%, polycarboxylate 4%, tea 4%, white carbon black 8%, kaolin 19%, the mixture is air-milled to obtain 65% isoprocarb·thiacloprid Wettable powder. The ratio is diluted and sprayed by 2500 times, and the effect of controlling rice planthoppers is 95.53% to 97.25% 72 hours after the application. 72 hours after the drug was used, the control effects were 81.54% and 79.74%, respectively. In the experiment, the inventor did not find that the test medicament had adverse effects on crops and was safe for beneficial insects.

Embodiment 355

[0072] Example 3 Experiment on the efficacy of 55% carbaryl·thiacloprid wettable powder in controlling cotton aphids

[0073] carbaryl 45%, thiacloprid 10%, alkyl aryl polyoxyethylene ether 4%, Sapindus japonica powder 4%, white carbon black 7%, kaolin 30%, the mixture is jet pulverized to obtain 55% methyl carbamide Nacarb thiacloprid wettable powder. The ratio is diluted and sprayed by 2000 times, and the effect of preventing and controlling cotton aphids is 94.36% to 96.64% within 72 hours after spraying. 72 hours after the drug was used, the control effects were 80.38% and 79.35%, respectively. In the experiment, the inventor did not find that the test medicament had adverse effects on crops and was safe for beneficial insects.

Abstract

The invention discloses an insecticidal composition containing thiacloprid. The insecticidal composition comprises A and B, wherein the A is carbamate insecticide of meta-tolyl-N-methyl carbamate, isoprocarb, fenobucarb or carbaryl; the B is thiacloprid; and the weight ratio of the component A to the component B is (1-80):(1-50). The insecticidal composition has the advantages that remarkably synergetic and constant prevention and control effects can be achieved after the active components A and B are compounded, the insecticidal spectrum can be expanded, the dosage of pesticide can be reduced, the residue of pesticide on crops can be reduced, and the environmental pollution can be reduced. The insecticidal composition is safe to human and livestock and good in environmental compatibility, and can be used for preventing insects from generating drug resistance.

Description

[0001] This application is a divisional application. The original application is a patent application "An Insecticidal Composition Containing Thiacloprid" of Shaanxi Meibang Pesticide Co., Ltd. The application number of the original application is: 201010150298.6, and the original application date is 2010.04.20. technical field [0002] The invention belongs to the technical field of agriculture and relates to the preparation and application of an insecticidal composition containing two active components. Background technique [0003] Thiacloprid, English common name Thiacloprid, chemical name is 3-(6-chloro-5-methylpyridine)-1,3-thiazolidine-2-cyanamide, molecular formula is C 13 h 5 N 4 SCl. [0004] Thiacloprid is a new type of chloronicotinoid insecticide, and its mechanism of action is different from other traditional insecticides. It mainly acts on the post-junction membrane of insect nerves. By combining with nicotinic acetylcholine receptors, it interferes with th...
