[0004] At present, the pesticide preparations with piflurid as the active ingredient are mainly 10% piflurid suspension concentrate, which is expensive to use in actual use and there is a risk of resistance. The mixed use of permethrin can not only achieve better control effect, but also has significant synergistic effect, and can reduce the cost of use, which is of positive significance for delaying the generation of pest resistance, crop safety, and comprehensive management of pest resistance

Embodiment 1

[0052] Weigh 5% pichridam, 15% etofenproxil, 3% TERSPERSE 4894 (produced by Huntsman, USA), 1% TERSPERSE 2500 (produced by Huntsman, USA), 2% diffusing agent NNO, 0.3% xanthan Glue, 5% propylene glycol, 0.5% benzoic acid, 0.5% organosilicon defoamer (trade name: s-29 is produced by Nanjing Sixin Applied Chemicals Company), 1% epichlorohydrin, and deionized water are added to 100% by weight share. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 20% suspension concentrate of piclopyrid-ethofenproxil.

[0053] The formula is used to prevent and control rice brown planthopper. The dosage per mu is 30g, diluted and sprayed with 50kg of water, and the control effect is 96.2% after 7 days and 95.4% after 14 days. The dosage of 10% etofenproxil SC is 80g per mu and the dosage of 10% pichampuddin SC is 30g per mu. Using the same method, the control effects of 7 days after the drug are respectively 85.6% and 86.8%. T...

Embodiment 2

[0055] Take by weighing 3% pyridoxam, 27% etofenproxil, 4% TERSPERSE 4894 (produced by Huntsman, U.S.), 1.5% TERSPERSE 2500 (produced by Huntsman, U.S.), 2% TERSPERSE 2425 (produced by Huntsman, U.S. produced), 0.2% magnesium aluminum silicate, 5% ethylene glycol, 0.5% formaldehyde, 0.5% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Company), 2% triphenyl phosphate 1. Add deionized water to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare a 30% suspension concentrate of piclopyrid-ethofenproxil.

[0056] The formula is used to prevent and control rice brown planthopper. The dosage per mu is 20g, diluted and sprayed with 50kg of water, and the control effect is 97.2% after 7 days and 93.6% after 14 days. The dosage per mu of 10% pichamprid suspension concentrate is 30g and that of 10% etofenproxil suspension concentrate is 80g per mu. Using the same method, ...

Embodiment 3

[0058] Take by weighing 2% pyraclon, 40% etofenproxil, 5% TERSPERSE 4894 (produced by Huntsman, U.S.), 2% TERSPERSE 2500 (produced by Huntsman, U.S.), 3% TERSPERSE 2425 (produced by Huntsman, U.S. produced), 0.2% xanthan gum, 5% propylene glycol, 0.5% benzoic acid, 0.5% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Company), 1% epichlorohydrin, Ionized water is added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 42% suspension concentrate of piclopyrid-ethofenproxil.

[0059] The formula is used to prevent and control rice planthoppers. The dosage per mu is 15g, diluted with 50kg of water and sprayed. The control effect is 98.3% after 7 days and 97.6% after 14 days. The dosage per mu of 10% pichamprid suspension concentrate is 30g and the dosage per mu of 10% etofenproxil suspension concentrate is 80g per mu. Using the same method, the control effects of...

Abstract

The invention discloses an insecticidal composite with paichongding and ethofenprox. The weight ratio of paichongding to ethofenprox is 1:20-10:1. The composite can be used to prepare water dispersing granule, wettable powder, suspending agent, oil dispersion, suspension emulsion, emulsifiable formulation or microemulsion formulation. The invention has reasonable components, good insecticidal effect and low cost of drugs, the activity and insecticidal effect are not the simple addition of activities of all components, compared with a signal preparation, the insecticidal composite has obvious insecticidal effect and synergistic effect, the generation of resistance is delayed, the amount of residual preparation is small, no pollution to crops is caused, the safety is good, and the security requirement of pesticide preparations can be realized. The invention has a better effect on preventing and controlling pests with sucking mouth parts on crops such as rice, wheat, vegetables and fruittrees.

Description

technical field [0001] The invention relates to an insecticidal composition containing pichamiprid and etofenproxil, belonging to the technical field of compound pesticides. Background technique [0002] The chemical name of piperidin is 1-((6-chloropyridin-3-yl)methyl)-5-propoxy-7-methyl-8-nitro-1,2,3,5,6,7 - Hexahydroimidazol[1,2-a]pyridine, the chemical formula is C 17 h 22 ClN 4 o 3 . Pichridam is a new type of high-efficiency, broad-spectrum, and low-toxic neonicotinoid insecticide. The mechanism of action is to act on the axonal receptors of insect nerves to block nerve conduction; Obvious antifeedant effect; acting on the stylet of piercing-sucking pests, making them unable to feed. Pichridam is mainly used to control Homoptera pests, and has a good control effect on rice planthoppers and other pests. Although pichridam has a new mechanism of action, because it is a new neonicotinoid insecticide, there is still a risk of resistance to long-term single use. [...
