Embodiment 180

[0068] Example 180% Zhongbuwei·clothianidin wettable powder control efficacy test of rice leaf roller

[0069] 50% of Zhongbucarb, 30% of clothianidin, 5% of polycarboxylate, 3% of sodium lauryl sulfate, 2% of saponin powder, 10% of kaolin, and the mixture is jet milled to obtain 80% of Zhongbucarb Clothianidin 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 95.88% to 96.36%. Times and 300 times of use, the 72-hour control effect was 80.13% and 77.41% 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

[0070] Example 265% Isoprocarb clothianidin wettable powder control rice planthopper efficacy test

[0071] Isoprocarb 47%, Clothianidin 18%, Lignosulfonate 4%, Tea Cucumber 4%, White Carbon Black 8%, Kaolin 19%, the mixture is jet milled to obtain 65% Isoprocarb Clothianidin Amine wettable powder. The ratio is 2500 times diluted and sprayed, and the effect of controlling rice planthopper 72 hours after the application is 95.48% to 97.67%. 50% clothianidin water dispersible granules and 20% isoprocarb emulsifiable concentrate are diluted 6500 times in the same way. And 300 times of use, the 72-hour control effect after drug is 81.65% and 79.27% ​​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 355

[0072] Example 355% Carbaryl Clothianidin Wettable Powder Control Cotton Aphid Drug Efficacy Test

[0073] Carbaryl 45%, clothianidin 10%, alkyl aryl polyoxyethylene ether 4%, sapindus powder 4%, white carbon black 7%, kaolin 30%, the mixture is jet milled to obtain 55% formazan Navel Wettable Clothianidin WP. The proportion is diluted and sprayed by 2000 times, and the effect of preventing and controlling cotton aphids is 94.35% to 96.34% 72 hours after the application. The 50% clothianidin water dispersible granule and 25% carbaryl emulsifiable oil are diluted 6500 times and 350 times respectively according to the same method. When used multiple times, the control effects were 80.34% and 79.45% 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 clothianidin-containing disinfestations composite, which comprises A active components and B active components, wherein the A components are selected from any one of carbamic acid esters insecticide: isoprocarb, meta-tolyl-N-meth ylcarbamate, sec-butyl phenyl-N-methyl carba or carbaryl; the B components are selected from clothianidin; and the weight parts ratio of the A active components to the B active components is 1-80:1-50. After the A active components are compounded with the B active components, the disinfestations composite has obvious effect-improving efficiency and continue control efficiency, enlarges the disinfestations spectrum, reduces the use amount of pesticide, reduces the residual quantity of the pesticide on crops, reduces the environment pollution, is safe to people and livestock, is environment-friendly, and leads injurious insects not to easily have 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] Clothianidin, English common name clothianidin, molecular formula is C 6 h 8 ClN 5 o 2 S, chemical name (E)-1-(2-chloro-1,3-thiazol-5-ylmethyl)-3-methyl-2-2-nitroguanidine. [0003] [0004] Clothianidin is jointly developed by Bayer AG and Takeda Corporation of Japan in the global market. This variety has been used in rice, fruit trees, tea, turf and ornamental crops in Japan. Clothianidin is another neonicotinoid insecticide discovered by Takeda after nitenpyram. It belongs to the second generation. Compared with the first generation of nitenpyram, its molecular structure is mainly different For: one is to replace the pyridine group with a chlorothiazole group; the other is to replace the nitromethylene part with a nitroimine. The methyl grou...
