Embodiment 1

[0017] Take 278 kg of the original drug of propargite with a purity of 90%, and 155 kg of the original drug of fenpropathrin with a purity of 97%, add solvent toluene, emulsifier alkylbenzene sulfonate, and auxiliary agent dioxane under stirring in the preparation kettle. 567 kg of methyl succinate sulfonate, etc. were filtered to obtain 1000 kg of emulsifiable concentrate, which contained 25% of propargite, 15% of fenpropathrin, and 0.15% of water, and the emulsification stability was qualified.

Embodiment 2

[0019] Take 100 kg of the original drug of fenpropathrin and 50 kg of the original drug of propargite, dissolve them in xylene respectively and blend them in the enamel reaction kettle with a heating device, then add the auxiliary agent epoxidized vegetable oil, emulsifier alkyl A total of 80 kg of alcohol polyoxyethylene ether calcium sulfate was stirred for 1.5 hours below 50°C, then xylene was added to make the total amount reach 77 kg, and stirring was continued for 2 hours to obtain a homogeneous transparent emulsifiable concentrate.

Embodiment 3

[0021] Take 100 kg of the original drug of fenpropathrin and 20 kg of the original drug of propargite, dissolve them in xylene respectively and blend them in an enamel reaction kettle with a heating device, and then add the emulsifier sulfonate-based alkyl sulfonic acid 80 kg of sodium, stirred at 50°C for 1.5 hours, then added xylene to make the total amount reach 75 kg, and continued to stir for 2 hours to obtain a homogeneous transparent emulsifiable oil.

[0022] Toxicity and insecticidal effect of the present invention are shown in Tables 1 and 2; with the citrus leafminer as the target pest, the mixture of fenpropathrin and imidacloprid in different proportions is used to measure the mortality rate, and the field experiment data are shown in Table 3.

Abstract

The present invention relates to an acaricide composition whose effective component is a mixture of fenpropathrin and propargite with the weight ratio of 1:0.05-5, and the weight percentage content of its effective component is 1-80%. According to the requirements it can be made into the various dosage forms, such as emulsifiable concentrate, water agent and power agent. The tests show that it not only has the good acaricidal effect, but also can raise yield and quality of crops simultaneously.

Description

1. Technical field: [0001] The invention relates to a pesticide composition, in particular to a pesticide composition for killing acarids used in agriculture. 2. Background technology: [0002] Mites, commonly known as spider mites, are serious agricultural hazards. The conventional pesticides currently used for prevention and control are prone to resistance due to repeated use, and the cost of prevention and control is also high. [0003] Fenpropethrin, chemical name: α-cyano-3-phenoxybenzyl, 2,3,3-tetramethylcyclopropane carboxylate, structural formula: [0004] This compound is a kind of pyrethroid insecticide and acaricide, and is the only one with acaricidal activity in this kind of medicament. It cannot be used as a single acaricide, but should be mixed with other acaricides. [0005] Propargite, chemical name: 2-(4-tert-butylphenoxy)cyclohexyl-2-alkynyl sulfite, structural formula: [0006] The compound is a low-toxicity broad-spectrum organosulfur acaricide, w...
