Embodiment 1

[0068] Example 1 80% Zhongbuwei · Thiacloprid wettable powder control efficacy test of rice leaf roller

[0069] Zhongbucarb 50%, thiacloprid 30%, lignosulfonate 5%, sodium lauryl sulfate 3%, saponin powder 2%, kaolin 10%, the mixture was jet milled to obtain 80% sec-butyl Wei Thiacloprid wettable powder. The ratio is diluted and sprayed by 3000 times, and the effect of controlling rice leaf roller 72 hours after the application is 95.14% to 96.87%. The 48% thiacloprid suspending agent and 20% secbutacarb emulsifiable concentrate are diluted 5500 times and 5500 times respectively in the same way. 300 times of use, the control effects were 80.77% and 76.41% 72 hours after the drug. In the experiment, the inventor did not find that the test agent had adverse effects on crops and was safe for beneficial insects.

Embodiment 2

[0070] Example 2 Efficacy test of 65% isoprocarb·thiacloprid wettable powder for controlling rice planthopper

[0071] Isoprocarb 47%, thiacloprid 18%, polycarboxylate 4%, tea dry 4%, white carbon black 8%, kaolin 19%, the mixture was jet milled to obtain 65% isoprocarb·thiacloprid wettable powder. The ratio is 2500 times diluted and sprayed, and the effect of controlling rice planthopper 72 hours after the application is 95.53% to 97.25%. The 48% thiacloprid suspending agent and 20% isoprocarb emulsifiable concentrate are diluted 3500 times and 300 times respectively according to the same method. When used multiple times, the control effects were 81.54% and 79.74% 72 hours after the drug. In the experiment, the inventor did not find that the test agent had adverse effects on crops and was safe for beneficial insects.

Embodiment 3

[0072] Example 3 Efficacy Test of 55% Carbaryl Thiacloprid WP in Controlling Cotton Aphids

[0073] 45% carbaryl, 10% thiacloprid, 4% alkylaryl polyoxyethylene ether, 4% sapinberry powder, 7% white carbon black, 30% kaolin, the mixture was jet milled to obtain 55% formazan Navir 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% 72 hours after the application. The 48% thiacloprid suspending agent and 25% carbaryl WP are diluted 3500 times and 350 times respectively according to the same method. When used multiple times, the control effects were 80.38% and 79.35% respectively within 72 hours after treatment. In the experiment, the inventor did not find that the test agent 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...
