Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of Pesticidal combination that contains penta pyrrole worm guanidine and fluorine pyridine worm amine nitrile.
Technical background
Sucking pest and Semiptera insect are all and inhale juice class pest.Sucking pest is a monoid larger in garden plant pests, often infests on spray, leaf, bud, bud, fruit, draws water, rob its nutrition, cause branches and leaves and steamed twisted roll song, even whole strain is withered or dead, causes China crops therefore to suffer heavy losses every year.Semiptera insect also great majority is phytophagy, inhales the juice of plant stem-leaf or fruit by thorn, and the crops of causing harm, fruit tree, forest or weeds, can cause harm to a certain degree to agricultural.
At present, mostly adopt nicotinoids, chrysanthemum ester class in farmland, organophosphate and carbamate pesticide is prevented and treated and is inhaled juice class pest, but due to long-term use, makes insect produce very high resistance.Therefore, develop new compounded pesticides efficient, that slow down pest resistance to insecticide significant.
Penta pyrrole worm guanidine structure:
Summary of the invention
In view of this, the object of the invention is to propose a kind of Pesticidal combination, can prevent generation or the delaying drug resistance speed of pest resistance to insecticide, the Pesticidal combination that use cost is low, preventive effect is good.
The present invention is achieved through the following technical solutions:
A kind of Pesticidal combination, is comprised of penta pyrrole worm guanidine and fluorine pyridine worm amine nitrile.
Wherein, the mass ratio of described penta pyrrole worm guanidine and fluorine pyridine worm amine nitrile is preferably 1～50: 75～1, more preferably 1～40: 50～1, most preferably be 5～35: 35～5.
Fluorine pyridine worm amine nitrile, English name Sulfoxaflor, chemical name [1-6-(trifluoromethyl) pyridin-3-yl] ethyl]-λ 4-sulfydryl cyanamide, molecular formula C
