Insecticide composition containing metaflumizone

Abstract

The invention discloses an insecticide composition containing metaflumizone. The first active component of the insecticide composition is the metaflumizone, the second active component of the insecticide composition is selected from one of the cartap, the monosultap, the dimehypo or the thiocyclam of a nereistoxin insecticide, and the weight ratio of the first active component to the second active component is (1:1) to (1:60). The insecticidal composition can be prepared into the medicament form of water dispersible granules, a suspending agent, wettable powder, microemulsion or water emulsion, can be used for preventing and treating rice-stem borers and cnaphalocrocis medinalis, has reasonable components, good insecticidal effect, low application cost and good safety to crops, has an obvious synergistic action, can slow down the generation of resistibility and conforms to the safety requirement of a pesticide preparation, and the activity and the insecticidal effect of the insecticidal composition are not the simple superposition of the activity of each component.

Description

technical field [0001] The present invention relates to an insecticide composition, in particular to a kind of metaflumizone as the first active ingredient, and nereistoxins such as cartap, monosultap, dimehypo or cyclosultap as the second active ingredient The insecticide composition belongs to the technical field of compound pesticides. Background technique [0002] Metaflumizone, English common name: metaflumizone, test code BAS320I, chemical name (IUPAC): (E+Z)-2-[2-(4-cyanobenzene)-1-(3-trifluoromethylbenzene ) Ethylene]-N-(4-trifluoromethoxybenzene) hydrazine oxamide; Molecular formula: C 24 h 16 f 6 N 4 o 2 . Metaflumizone is an insecticide with a new mechanism of action. It binds to the receptors of sodium ion channels to block the passage of sodium ions, and has no cross-resistance with pyrethroids or other types of compounds. The drug mainly enters into the body of the pest to kill the pest through gastric poisoning, and the contact effect is small and has n...

Problems solved by technology

[0007] At present, the pesticide preparations with metaflumizone as the active ingredient are mainly 240 g / L metaflumizone suspending agent, and 20% metaflumizone EC. In actual use, the quick effect is good, but the long-lasting Generally, the cost of use is high; nereistoxins, as commonly used insecticides in China, have always been accepted by users for their insecticidal effect and cost-effectiveness, but the resistance is increasing year by year. The inventor unexpectedly discovered that metaflumizone and Nereistoxins such as Insecticide, Dimetap, Dimehytap or Dimetap can be used in a reasonable mix, which has a significant synergistic effect, can reduce the cost of use, and slow down the generation of pest resistance
