Description
Technical field
The present invention relates to pesticide field, is the ultra low volume liquids of fluorine-containing pyridine worm amine nitrile and carbamate insecticide specifically, mainly by ultra low volume spraying, low-gallonage spraying or ultra low volume electrostatic spray, realizes the effective control to crop pest.
Background technology
Fluorine pyridine worm amine nitrile is by Tao Shi benefit agriculture development of new insecticide, English name: sulfoxaflor, chemical name: [1-6-(trifluoromethyl) pyridin-3-yl] ethyl]-λ 4-sulfydryl cyanamide, molecular formula is C
