Technical field
The invention belongs to field of pesticides, relate to a kind of binary pesticide composition and purposes.
Background technology
Insecticide has significantly effect in terms of preventing and treating agriculture and forestry injurious insect or urban health insect.
Chinese invention patent CN101333213A discloses a kind of 1-substituted pyridyl-pyrazol acid amide compounds and control thereof
Insect pest and the purposes of disease, wherein compound 1.25 (hereinafter referred to as compound A) can be used for preventing and treating various pests, especially
Lepidoptera pest is had prominent prevention effect.
Containing the insecticide of single-activity component, Pest control uses continuously, easily make insect develop immunity to drugs.Pass through
The insecticide of two kinds of active components is compounded into blending ingredients by a certain percentage, often can improve preventive effect, reduces effective ingredient
Consumption, cost-effective, the generation of pest resistance to insecticide can be delayed simultaneously.
Although prior art disclosing compound A or its homologue general and can producing with other Mixture Use of Insecticides additional excellent
Point and effect, but the technical scheme of the binary pesticide composition containing compound A has no concrete open.
Summary of the invention
Present invention aim at developing a kind of binary pesticide composition containing compound A, to meet agricultural and urban health
The demand that insecticide effect is day by day improved by field pest control aspect and kind is constantly updated.
Technical scheme is as follows:
A kind of binary pesticide composition, active component one is selected from compound A, and active component two is selected from Macrolide parasite killing
Agent；
Described compound A has a following structure:
Described macrolide insecticide includes avilamycin (Abamectin), emamectin-benzoate
(Emamectin benzoate is called for short emamectin benzoate), pleocidin (spinosad), ethyl pleocidin (spinetoram),
Emaricin (emamectin) or milbemectin (milbemectin) etc..
The preferred avilamycin of active component two, emamectin benzoate or pleocidin in the binary pesticide composition of the present invention.
In the binary pesticide composition of the present invention, the ratio of weight and number of two kinds of active components is 1:99-99:1, is preferably
1:20-20:1。
Indoor biological determination of activity demonstrates that the binary pesticide composition of the present invention has potentiation.Such as, compound A
In the range of 1:20-20:1, multiple target is shown good potentiation with avilamycin；Compound A and emamectin benzoate exist
In the range of 5:1-1:2, compound A and pleocidin in the range of 5:1-1:1, all demonstrate potentiation.

Indoor biological determination of activity
The embodiment 15 compositions containing the compound A synergism determination to diamondback moth
For examination object: diamondback moth (Plutella xylostella), 2 instar larvaes, the sensitive strain of indoor feeding.
Test condition: temperature: 24～26 DEG C, humidity: RH60%, illumination: L:D=14:10
Test method: use infusion process to process, fetched by the cabbage leaves of greenhouse production, make diameter 2cm leaf dish, will
Leaf dish impregnates 5s in medicinal liquid, dries in the shade after taking-up, puts in the 9cm culture dish being lined with filter paper, selects the examination worm of neat and consistent
Access in culture dish, often process and be repeated 4 times.Examination worm after processing is placed in observation ward, routine observation examination worm response situation,
48h " Invest, Then Investigate " is dead, borer population of living, and calculates mortality rate.
Evaluating and use Bliss method, the method is one of classical way evaluating mixture effect.The independence that Bliss proposes according to it
Synergy concept is thought, theoretical mortality rate P during Mixture Use of Insecticides can calculate with following formula:
P=Pm+Pn(1-Pm)
PmIt it is the mortality rate (%) of the first active component target when concentration is m；PnIt is that the second active component concentration is
The mortality rate (%) of target during n.
If two kinds of active component actuals of target after mixing with finite concentration more than theoretical mortality rate P, then judge
Two kinds of active components are used in mixed way under setting concentration has potentiation, otherwise is then antagonism.
The results are shown in Table 1.
