A kind of Pesticidal combination containing Bifenazate and chlorine fluorine cyanogen insect amide
Technical field
The present invention relates to a kind of Pesticidal combinations, more particularly, to a kind of desinsection containing Bifenazate and chlorine fluorine cyanogen insect amide
Composition.
Background technology
The resistance problem of agricultural pests is a global problem.With the continuity of Chemical Control of Harmful Insects, Pesticide use
The increase of amount and it is unscientific use pesticide, pest resistance getting worse, the pest species for generating resistance are on the increase.Especially
Cause harm serious mite class and Lepidoptera class pest to agricultural production, resistance level is higher, and resistance development speed is relatively fast.Together
When, the use pesticide of high intensity causes Residual Pesticides in Farm Produce is exceeded, environmental pollution is serious to increase with peasant's drug cost
Deng being unfavorable for agricultural sustainable development.In addition, the use of single pesticide is easier to cause drug resistance.By by different pesticide product
Kind mixture, filters out rational formula, can effectively improve practical control effect, reduces dosage, reduces cost, delays pest anti-
The generation of pharmacological property extends the service life of medicament and a kind of important means of integrated pest management.Therefore, research and development are high
Effect, low toxicity, the pesticide of environmental protection and Recompounded pesticide have positive effect to agricultural sustainable development.
Bifenazate (bifenazate) is a kind of new selective foliar spray acaricide, Central nervous conduction system
The GABA receptors of system have unique effect, right with ovicidal activity and to being knocked down active (in 48~72 hours) at the rapid of mite
Each life stage of mite is effective, and the lasting period is long.Predatory mite is influenced it is minimum, to honeybee and other beneficial insects almost without
It influences, is very suitable for the comprehensive treatment of pest.Registered crop controlling object includes apple tree red spider etc..
Chlorine fluorine cyanogen insect amide (cyhalodiamide) is the novel pesticide that Zhejiang Provincial Chemical Engineering Research Inst is voluntarily developed, tool
Just like lower structure formula (I):
The insecticide belongs to novel phthalic amide insecticides, by activating blue Buddhist nun's alkali recipient cell Intracellular calcium release logical
Road leads to the runaway release for storing calcium ion, is few in number at present to act on insect cell orchid Buddhist nun alkali (Ryanodine)
The compound of receptor.There is wide spectrum preventive effect to lepidoptera pest, generates, be extremely suitable for existing with existing insecticide no interactions resistance
Insecticide generates the prevention of the pest of resistance.
Drug cost is higher when Bifenazate and chlorine fluorine cyanogen insect amide are used alone, and limits its popularization to a certain extent
Using, and long-term exclusive use be easy to cause pest resistance degree and is continuously increased.Therefore, by Bifenazate and chlorine fluorine cyanogen insect amide
Compounded has positive effect for efficient, less toxic, environment-protection pesticide exploitation.
