Embodiment 1

[0020] The equipment used in this example is all conventional equipment in the pesticide industry, and the compounding process includes steps such as dissolution of the original drug, quantification, compounding, content detection, and co-toxicity coefficient detection. Put the original drug into the container according to the following ratio, add solvent and emulsifier, stir well and evenly, carry out active ingredient detection, and finally pack.

[0021] The composition insecticide of the present embodiment comprises each component of following percentage by weight:

[0022] Fipronil 30%, Beta-cyhalothrin 20%,

[0023] Nonylphenol polyoxyethylene ether 5%, the balance is xylene. The dosage form of the product is emulsifiable concentrate.

Embodiment 2

[0025] The mode of operation is the same as in Example 1, and the difference is that the composition insecticide of the present embodiment includes the following components in percentage by weight: 20% of fipronil, 30% of lambda-cyhalothrin, alkylbenzene The mixture of calcium sulfate and phenylethylphenyl polyoxyethylene-polyoxypropylene ether is 10%, and the balance is water. The dosage form of the product in this embodiment is water emulsion.

Embodiment 3

[0027] Mode of operation is the same as Example 1, and its difference is that the composition insecticide of the present embodiment comprises each component of following percentage by weight:

[0028] Fipronil 25%, Beta-cyhalothrin 20%,

[0029] The mixture of calcium alkylbenzene sulfate, nonylphenol polyoxyethylene ether, and styrene-ethylphenyl polyoxyethylene-polyoxypropylene ether is 5%, and the balance is water. The dosage form of the product in this embodiment is water emulsion.

[0030] Adopt the domestically recognized mixed agent screening method—co-toxicity coefficient assay method, in the room, measure the synergistic effect of diamondback moth with the medicament described in the above-mentioned embodiments of the present invention, the contact toxicity test of diamondback moth shows that its co-toxicity coefficient range It is 128-169, and its synergistic effect is remarkable, wherein: the co-toxicity coefficient of embodiment 1 is 128, and the co-toxicity coeff...

Abstract

The invention discloses a fipronil-containing composition insecticide which is characterized by comprising the following ingredients in percentage by weight: 20-30 percent of fipronil, 20-30 percent of lambda-cyhalothrin, 5-10 percent of an emulsifier and the balance being solvent, wherein the solvent is selected from dimethylbenzene, water or dichloromethane; the emulsifier is selected from one or several of nonylphenol polyoxyethylene ether, alkylbenzene calcium sulfate, phenethyl phenylpolyoxyethylene-polyoxyethylene ether. According to the composition insecticide, the action mechanisms of the ingredients are different, the action mode achieves high complementarity, the antagonism is avoided, the synergistic effect is obvious, the insecticidal spectrum is widened, and pesticide resistance of injurious insects is unlikely to be caused.

Description

technical field [0001] The invention relates to a composite insecticide, in particular to a crop insecticide compounded by fipronil and a low-toxicity insecticide. Background technique [0002] Fipronil (Fipronil, Fipronil), chemical name: 5-amino-1-(2,6-dichloro-4-trifluoromethylphenyl)-4-trifluoromethylsulfinylpyrazole- 3-Nitronitrile, phenylpyrazole insecticides, which are mainly stomach poisoning, have contact killing and certain systemic effects, have a long persistence period, are low-to-medium toxicity pesticides, and are broad-spectrum insecticides. It is effective against rice borers and planthoppers. But it is easy for pests to develop resistance. In the process of use, there are problems of slow drug effect and poor quick effect. Among the agents for preventing and controlling rice borers, the effect on rice stem borer is not good, and the price is relatively high. [0003] Practice has shown that mixing various heterogeneous pesticides to make a compound agent...
