example 1～12

[0045]Example 1~12 wettable powder

[0046] Tefluthrin, active ingredient B, dispersant, wetting agent and filler are mixed, mixed uniformly in a mixing tank, pulverized by a jet mill and then mixed uniformly to produce the wettable powder product of the present invention. See Table 1 for details.

[0048]

example 13～24

[0049] Example 13~24 water dispersible granules

[0050] Tefluthrin, active ingredient B, dispersant, wetting agent, binder, disintegrant, and filler are jet-milled together to obtain the required particle size, and the granulation material is obtained. The water-dispersible granule product of the present invention is obtained by quantitatively sending the material into a fluidized bed granulation dryer for granulation and drying. See Table 2 for details.

Abstract

The invention discloses a high-efficiency insecticide composition which is composed of an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from tefluthrin, the active ingredient B is selected from any of the following compounds: indoxacarb, buprofezin, MTMC (Tolyl Methyl Carbamate) and isoprocarb, and the weight ratio of the active ingredient A to the active ingredient B is 1:70 to 70:1. The high-efficiency insecticide composition can prevent and control various insects, has an obvious synergism effect, expands an insecticidal spectrum, reduces the pesticide using amount, reduces the residual quantity of pesticide on the crop, and alleviates environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to the application of a high-efficiency insecticide composition on crop pests. Background technique [0002] Tefluthrin (Tefluthrin) chemical name: 2,3,5,6-tetrafluoro-methylbenzyl (cis)-(1RS,RS)-3-(2-chloro-2,3,3-trifluoro Prop-1-enyl)-2,2-dimethylcyclopropanecarboxylate, molecular formula: C 17 h 14 CIF 7 o 2 . Tefluthrin is the first pyrethroid that can be used as a soil insecticide. It is highly effective against Coleoptera, Lepidoptera and Diptera insects and can be applied in the form of granules, soil spray or seed treatment. It has good volatility and can fully migrate in the gas phase to control soil pests. The half-life in the field is about one month, so it can maintain a long residual effect on pests without causing long-term residues in the soil. [0003] Indoxacarb chemical name: 7-chloro-2,3,4a,5-tetrahydro-2-[methoxycarbonyl(4-trifluoromethoxyphenyl)carbamoyl]...
