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 the juice class pest.Sucking pest is bigger in a garden plant pests monoid, often infests on spray, leaf, bud, bud, the fruit, draws water; Rob its nutrition; Cause branches and leaves and steamed twisted roll bent, even whole strain is withered or dead, causes China crops therefore to suffer heavy losses every year.Semiptera insect also great majority is a phytophagy, and through the juice of thorn suction plant stem-leaf or fruit, the crops of causing harm, fruit tree, forest or weeds can be caused harm to a certain degree to agricultural.
At present, adopt nicotinoids, chrysanthemum ester class in the farmland mostly, organic phosphates and carbamate chemicals for agriculture are prevented and treated and are inhaled the juice class pest, but because long-term the use makes insect produce very high resistance.Therefore, the new compounded pesticides efficient, that slow down pest resistance to insecticide of exploitation is significant.
Penta pyrrole worm guanidine structure:
Summary of the invention
In view of this, the objective of the invention is to propose a kind of Pesticidal combination, make its generation that can prevent pest resistance to insecticide or delaying drug resistance speed, the Pesticidal combination that use cost is low, preventive effect is good.
The present invention realizes through following technical scheme:
A kind of Pesticidal combination is made up of penta pyrrole worm guanidine and fluorine pyridine worm amine nitrile.
Wherein, the mass ratio of said 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
