The invention belongs to technical field of pesticide, a kind of Pesticidal combination containing pyraflufen-ethyl and bromothalonil is specifically disclosed, effective active composition is pyraflufen-ethyl and bromothalonil, and the weight ratio of pyraflufen-ethyl and bromothalonil is 15:1-1:15.The present invention expands insecticidal spectrum by the rational mixture between pyraflufen-ethyl and bromothalonil, improves drug effect, reduces dosage, mitigates the pollution to environment, safe and efficient.
Description
Technical field
The present invention relates to a kind of pesticidal preparations, especially a kind of Pesticidal combination containing pyraflufen-ethyl and bromothalonil.
Background technique
Due to the long-term single insecticide dependent on using a certain type, pest is easy to produce drug resistance, chemistry is caused to kill
The dosage of worm agent sharply increases, and not only increases production cost, and largely kills the natural enemy and pollution environment of pest, causes
The Rampant damage of pest.Pyraflufen-ethyl is that have excellent insecticidal activity, all effective to most of agricultural pests, and dosage is low, in ring
It degrades quickly in border, does not injure natural enemy and other non-target organisms, be a kind of outstanding biological insecticides, the disadvantage is that unstable
It is fixed.Therefore, it is necessary to a kind of new pesticidal preparations.
Summary of the invention
The object of the present invention is to provide a kind of Pesticidal combination containing pyraflufen-ethyl and bromothalonil, passes through pyraflufen-ethyl and bromine bacterium
Rational mixture between nitrile expands insecticidal spectrum, improves drug effect, reduces dosage, mitigates the pollution to environment, safe and efficient.
The purpose of the present invention is what is be achieved through the following technical solutions, a kind of Insecticidal combinations containing pyraflufen-ethyl and bromothalonil
Object, characterized in that the effective active composition of the Pesticidal combination is pyraflufen-ethyl and bromothalonil, the weight of pyraflufen-ethyl and bromothalonil
Than for 15:1-1:15.
Preferably, pyraflufen-ethyl and the weight ratio of bromothalonil are 10:1-1:10 in the Pesticidal combination.
Preferably, pyraflufen-ethyl and the weight ratio of bromothalonil are 7:1,3:1,1:3,1:7 in the Pesticidal combination.
The Pesticidal combination that the present invention contains pyraflufen-ethyl and bromothalonil be made wettable powder, water dispersible granules, suspending agent,
Microcapsule suspending agent, aqueous emulsion or microemulsion.
The Pesticidal combination that the present invention contains pyraflufen-ethyl and bromothalonil is used to prevent and treat rice, vegetables, pest answers on cotton
With.
Compared with prior art, the invention has the following advantages:
First, after pyraflufen-ethyl and bromothalonil mixture, the shortcomings that pyraflufen-ethyl being overcome to be easy to produce resistance, making for medicament can be widened
With range, drug effect is improved.There is important role to the resistance management of pest.
Second, after pyraflufen-ethyl and bromothalonil mixture, not only maintain many merits of botanical pesticide, but also mixture
Dosage reduces, and drug effect increases substantially, which has great importance to the development and application of natural insecticide.
Third can greatly mitigate to various as preparing the compatibility of each substance needed for the insecticides and proportion rationally
Pest
The toxic action of natural enemy, it is small to the pollution of ecological environment, be conducive to protect safety of human and livestock.
