C22H19O3NCL2.Effective cypermethrin is the lepidoptera pest occurred on main preventing and treating crops, the medicament be non-internal-absorting but
Possesses the insecticide tagged with stomach poison function.By being interacted with insect sodium channel to have destroyed the function of nervous system.It is high
It is a kind of broad spectrum insecticide to imitate cypermethrin, and very high insecticidal activity is respectively provided with to being permitted various pests.It can be applied to more seed pods
The crops such as tree, various vegetables, grain and cotton oil tea and a variety of forests, plurality of Chinese plant, oriental tobacco budworm, bollworm, diamondback moth, beet night
Moth, prodenia litura, tea geometrid, pink bollworm, Phytophthira, liriomyza bryoniae class, beetle, stinkbug class, wood louse class, thrips class, heart-eating worm
The various pests such as class, leaf rollerses, caterpillar class, slug moth class and phyllocnistis citrella stainton, ceroplastes rubens are respectively provided with good killing effect.
Rynaxypyr：English name：Chlorantraniliprole, chemical name：The bromo- N- of 3- [the chloro- 2- first of 4-
Base -6- [(methyl-carbamoyl) benzene] -1- (3- chloropyridine -2- bases) -1- hydrogen-pyridine -5- formamides, molecular formula：
C18H14N5O2BrCl2.Medicament category O-formammidotiazol-benzamide insecticide.Blue Buddhist nun's alkali acceptor is mainly activated, release is smooth
The calcium ion of storage in flesh and striated muscle cell, cause muscle regulation weak, paralysis, until last insect is dead.This effectively into
Divide and show, to mammal and the extremely significant selective difference of insect orchid Buddhist nun's alkali acceptor, to substantially increase to mammal and its
The security of his vertebrate.Rynaxypyr high-efficiency broad spectrum, to the Noctuidae of Lepidoptera, Pyralidae, Carposinidae, leaf roll
Moth section, miller section, diamond-back moth section, Gelechidae, Gracilariidae etc. have good control effect, moreover it is possible to control coleoptera Culculionidae, leaf
First section；Diptera Agromyzidae；A variety of non-lepidoptera pests such as Bemisia tabaci.
Insecticide is used due to largely unreasonable for a long time, insect generates the serious resistance to the action of a drug to various insecticides, uses
Dose improves constantly, and adds the residual hazard on crops, influences health.Therefore, seek effectively and and can reduction environment dirt
The prevention and controls of dye are necessary.Inventor is had found efficient by the research of a large amount of indoor biometricses and field control effectiveness test
Cypermethrin and Rynaxypyr are combined application, are not only able to reduce dosage, expand insecticidal spectrum, it is lethal to improve insect
Speed, extends the duration of desinsection, and delaying drug resistance is environmentally safe.

Subjects：Corn/corn borer
Test method：Standard method NY/T 1154.14-2008 are surveyed with reference to raw, using invading leaf method.Will be fresh, open and flat with card punch
Host's blade break into leaf dish, avoid choosing the big and thick position of vein as far as possible during punching.Leaf dish is immersed into 10s in decoction to be measured
Afterwards, taking-up is dried, and face of blade is laid in plus in the culture dish of good agar down with tweezers, accesses test worm, is often repeated not
Less than 10.Often processing is no less than 4 repetitions, and sets the processing without medicament as blank control.The test worm of processing is placed in
Temperature is（25±1）DEG C, humidity 60%-80%, photoperiod L:D=（16:8）Raise and observe under h.
48h checks test worm death condition after processing, records total borer population and death toll respectively.It is special according to test requirements document and medicament
Point, it can shorten or extend control time.
According to survey data, the corrected mortality of each processing is calculated, and the co-toxicity coefficient of mixture is calculated according to the abundant methods of Sun Yun
（CTC values）.Use statistical analysis system（SAS）, data handling system（DPS）Analyzed Deng software, calculate the LC of each medicament50、
