Background technique
Diamondback moth category lepidoptera diamond-back moth section, is the important resistant insect of crop in cruciferae, first instar larvae only feeding mesophyll,
Leave epidermis, form spot transparent one by one in dish leaf, be commonly called as blank, 3~4 instar larvaes dish leaf can be eaten into hole and
It incises, full leaf, which is eaten, when serious reticulates, and thereby results in quality of vegetable variation, causes serious economic loss.
Ethyl pleocidin is novel plant source insecticides, and English common name: Spinetoram, ethyl pleocidin are
It is generated from more armfuls of bacterium (Saccharopolyspora spinosa) fermentations of unwrapping wire bacteria thorn sugar, is pleocidin (Spinasad)
Derived product, the mechanism of action be act on insect nerve in nAChR and r- aminobutyric acid receptors, cause
Keep polypide insensitive to the signal transfer reaction of excitability or inhibition, influence normal nervous activity, until dead.
The perennial liana of Celastrus angulatus category Celastraceae Celastrus, is distributed widely in the mound of China the Yellow River, the Yangtze river basin
Mound and mountain area.The root skin and stem skin of Celastrus angulatus contain there are many strength insecticidal constituent, separate mirror from root skin or seed at present
Make dozens of noval chemical compound, especially obtain 4 crystallizations from kind of oil, i.e. Celastrus angulatus ester I- IV, obtained from root skin 5 it is pure
Natural products, i.e. Celastrus angulatus I-V.The important active insecticidal components of these Celastrus angulatus are referred to as Celastrus angulatus (celastrus
angulatus)。
Diamondback moth thereby results in diamondback moth and resists to single medicament because its fertility is strong, life cycle is short, takes place frequently throughout the year
Sexual development is very fast, and control efficiency is undesirable.And compounded by the farm chemical ingredients of different role mechanism, it is to delay pest and disease damage anti-
One simple and convenient and fast approach of property.It is used to prevent and treat the pesticide of diamondback moth with ethyl pleocidin and Celastrus angulatus mixture at present
Mixture there is no report and application.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of Insecticidal combinations containing Celastrus angulatus and ethyl pleocidin
Object, to solve in the prevention and treatment of diamondback moth because single frequent using pest resistance to insecticide aggravation, mu use caused by ethyl pleocidin
Practical problem at high cost.
The invention adopts the following technical scheme: a kind of Pesticidal combination containing Celastrus angulatus and ethyl pleocidin, effectively
Ingredient is made of ethyl pleocidin and Celastrus angulatus, and the weight ratio of ethyl pleocidin and Celastrus angulatus is 2-5:1-2, preferably
, the weight ratio of ethyl pleocidin and Celastrus angulatus is 5:1.
The Pesticidal combination, ethyl pleocidin are 2-10% in the weight percent of composition, and Celastrus angulatus exists
Weight percent in composition is 0.5-2%.
The Pesticidal combination is added corresponding adjuvant, water is made according to method known in those skilled in the art
The agriculturally acceptable dosage form such as emulsion, suspending agent.
The adjuvant of the Pesticidal combination include solvent, emulsifier, wetting agent, stabilizer, defoaming agent, thickener or
It is other to be beneficial to the effective component stable known substance played with drug effect in the formulation, it is all common or fair in field of pesticide preparation
Perhaps the various composition used.
Compared with prior art, the present invention has following technical effect:
(1) ethyl pleocidin and Celastrus angulatus mixture can be reduced each the virulence obvious synergy of diamondback moth
The amount of application of single dose improves control efficiency, mitigates pesticide residue, reduces spraying times and dosage, reduces pesticide cost.
(2) ethyl pleocidin is different with the mechanism of action of Celastrus angulatus, mutually mixed to delay pest resistance to insecticide, favorably
In the service life for extending ethyl pleocidin.
Specific embodiment
Below in conjunction with the indoor joint toxicity measuring test and field medicine effect test for measuring biocidal activity to of the invention
Technical solution and technical effect are described further, and percentage of the present invention is weight percentage.
Inventor has found that ethyl pleocidin and Celastrus angulatus are mixed right in a certain range by a large amount of screening test
Diamondback moth on brassicaceous vegetable has synergistic function, and effect is not only the simple addition of two kinds of medicaments, specific to use
Following bioassay example is illustrated.
One, bioassay example
Embodiment 1: the indoor toxicity test of ethyl pleocidin, Celastrus angulatus and its mixture to wild cabbage plutella xylostella
Test connects worm method using leaching leaf: reagent agent being made into certain density mother liquor, then is diluted to 5 gradients with clear water
Concentration is stand-by, if clear water is control.It takes fresh cabbage leaves to be cut into the almost the same segment of size of about 50mm long, will shear
Blade prepared for being impregnated 10 seconds in reagent liquid, take out and it allowed to be put into the culture dish for being lined with filter paper in advance after natural drying
In (φ 120mm).Then 3 instar larvae of diamondback moth, 15, every ware, 3 repetitions of each concentration are accessed in ware.It is placed in greenhouse and trains
Support, the inspection record death condition after 72 hours, calculate the death rate, and according to probit analysis find out virulence regression equation,
