When in use, the insecticide solution of the invention has higher insecticidal activity compared with other insecticide solution with the same active constituents.
Description
Technical field
The present invention relates to a kind of insecticide solution preparation and application thereof
Background technology
Pyrethroid coumpound can be used to prevent and treat mosquito, and has insecticidal activity preferably, this widely the people it.Because it has efficiently, low toxicity, low-residual, environment compatibility are good, obtained application widely in the prevention and control field of sanitary insect pest.But along with the increase of service time, mosquitos and flies has produced certain resistance to some traditional pyrethroid products (as tetramethrin) etc.
More or less there are some defectives in former pyrethroid compound on basic insecticidal activity or vapour pressure, can not be satisfactory.
Summary of the invention
The objective of the invention is in order to overcome the existing lower defective of insecticidal materials activity.The inventor by discover insecticide solution of the present invention have that consumption is few, the kill pests kind is many, to advantages such as person poultry harmless.
The present invention is achieved through the following technical solutions above-mentioned purpose:
A kind of insecticide solution, it is formulated by a certain percentage to contain solute A, solvent B and assistant agent C; It is trans-2,3,5 that described solute A is expressed as, 6-tetrafluoro-4-methoxy benzyl-3-(3,3,3-three fluoro-2-chloro-1-acrylic)-2,2-dimethyl cyclopropane carboxylic acid ester
Solvent B is one or more the mixture in monocarboxylic esters, dicarboxylic esters, aliphatic acid ester, fragrant hydrocarbon system acid esters or the ether that contains 6～15 carbon atoms, described assistant agent C is the mixture of other active insecticidal components, synergist and stabilizing agent, by weight, its proportioning A is 0.1%～40.0%, B is 48%～99.6%, and C is 0.3～12.0%.
A kind of insecticide solution, its prescription A is 5.0%～25.0%, and B is 68.0～94.0%, and C is 0.3～12%.
Described solute (A) is 0.1～25.0: 100 with solution (A+B) weight ratio.
