Problems solved by technology

At the same time, triazotin and propargite are easy to develop resistance to pests, and it is very easy to cause serious damage when used at high temperatures. In view of this, fenpropathrin and bromofen are rarely used in the control of spider mite and other mites, and It is not easy to produce resistance, which is the direction of vigorous development in the future

Embodiment 1

[0019] Now through the test according to the following method to prepare the effective content of 10% fenpropathrin bromofen water emulsion, its preparation method is:

[0020] First dissolve 9.5 grams of fenpropathrin and 0.5 grams of bromofen with 20 grams of xylene, then add 7 grams of fatty acid polyoxyethylene ester and 4 grams of alkylphenol polyoxyethylene ether, mix well, and then slowly add water 55.5 grams, while constantly stirring, then add 3 grams of glycerol, fully shear in the shearing machine, finally add 0.5 grams of xanthan gum and fully mix.

Embodiment 2

[0022] Now through the test according to the following method to prepare the effective content of 20% fenpropathrin bromofen water emulsion, its preparation method is:

[0023] First dissolve 18 grams of fenpropathrin and 2 grams of bromofen with 20 grams of xylene, then add 10 grams of fatty acid polyoxyethylene ester and 6 grams of alkylphenol polyoxyethylene ether, mix well, and then slowly add water 39.2 grams, while constantly stirring, then add 4 grams of glycerol, fully shear in the shearing machine, and finally add 0.8 grams of xanthan gum and fully mix.

Embodiment 3

[0025] Now through the test, the effective content of 25% fenpropathrin bromofen water emulsion will be prepared according to the following method. The preparation method is as follows:

[0026] First dissolve 20 grams of fenpropathrin and 5 grams of bromofen with 30 grams of xylene, then add 8 grams of fatty acid polyoxyethylene ester and 4 grams of alkylphenol polyoxyethylene ether, mix well, and then slowly add water 28 grams, while stirring constantly, then add 4 grams of glycerol, fully shear in the shearing machine, and finally add 1 gram of xanthan gum and mix well.

Abstract

The invention relates to a composite of fenpropathrin and fenisobromolate, and the composite is mainly used in an acaricide. The formulation of the composite is an aqueous emulsion. The composite mainly consists of 5 percent to 70 percent of fenpropathrin by weight, and 0.1 percent to 20 percent of fenisobromolate by weight. According to the actual needs at present, the optimal ratio of the two components is 10-20: 0.5-10 and the rest are additives, which mainly comprise 5 percent to 15 percent of surfactant, 5 percent to 40 percent of organic solvent, 1 percent to 4 percent of anti-freeze agent, 0.5 percent to 5 percent of additive and water is supplemented until the total percentage reaches 100 percent. The composite which mainly aims at red spiders of oranges has the advantages of solving the unfavorable factors of ordinary emulsifiable concentrates such as heavy residual, easy combustion and unsafe production, transportation and use, greatly reducing the using cost of peasants and ensuring environmental safety.

Description

Technical field: [0001] The invention relates to an emulsion in water of a mixture of fenpropathrin and bromofen, which has the effect of killing manganese. technical background: [0002] Acarids are mainly red spiders, which are agricultural pests that seriously damage crops. At present, they are mainly used in the control of triazoltin, propargite, and other agents. At the same time, triazotin and propargite are easy to develop resistance to pests, and it is very easy to cause serious damage when used at high temperatures. In view of this, fenpropathrin and bromofen are rarely used in the control of spider mite and other mites, and It is not easy to produce resistance, which is the direction of vigorous development in the future. [0003] Fenpropathrin (chemical name: α-cyano-3-phenoxybenzyl-2,2,3,3-tetramethylcyclopropane carboxylate) is also called Misulli in foreign countries. The structural formula is: [0004] [0005] Fenpropathrin is a pyrethroid insecticide, ...
