Embodiment 180

[0066] Example 180% Zhongbuwei·thiacloprid wettable powder control efficacy test of rice leaf roller

[0067] 50% Zhongbucarb, 30% Thiacloprid, 5% Lignosulfonate, 3% Sodium Lauryl Sulfate, 2% saponin powder, 10% Kaolin, the mixture is jet milled to obtain 80% Zhongbu Wei Thiacloprid wettable powder. The proportion 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 72-hour control effects were 80.77% and 76.41% respectively. In the experiment, the inventor did not find that the test agent had adverse effects on crops and was safe for beneficial insects.

Embodiment 265

[0068] Example 265% Isoprocarb·thiacloprid wettable powder control efficacy test of rice planthopper

[0069] Isoprocarb 47%, thiacloprid 18%, polycarboxylate 4%, tea 4%, white carbon black 8%, kaolin 19%, the mixture is jet milled to obtain 65% isoprocarb·thiacloprid wettable powder. The proportion is diluted and sprayed by 2500 times, 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 355

[0070] Example 355% carbaryl thiacloprid wettable powder control cotton aphid efficacy test

[0071] 45% carbaryl, 10% thiacloprid, 4% alkyl aryl polyoxyethylene ether, 4% Sapindus powder, 7% white carbon black, 30% kaolin, the mixture is jet milled to obtain 55% formazan Navir Thiacloprid wettable powder. The proportion 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 wettable powder 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% 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.

Abstract

The invention discloses a pesticidal composition containing thiacloprid, containing A and B, wherein A is selected from any one of the following carbamate pesticides: metolcarb, isoprocarb, fenobucarb or carbaryl; B is thiacloprid; the ratio of parts by weight of the active ingredients A and B is 1-80:1-50. The composition has the following advantages: after A and B are compounded, the composition has obvious synergy and sustained control effect, expands the pesticidal spectrum, reduces the pesticide consumption and the residues of the pesticides on the crops, lightens environmental pollution, is harmless to people and livestock, has good environment compatibility and ensures the pests not to easily generate resistance to drugs.

Description

technical field [0001] 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 [0002] 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. [0003] 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 the normal conduction of the insect nervous system, causing blockage of nerve channels, resulting in a large accumulation of acetylcholine, which makes insects extremely excited, body convulsions, paralysis and death. . It has strong systemic, contact and stomach poisoning effects, and has no cross-resistance with ...
