Incise, full leaf is eaten and reticulated when serious, thereby result in quality of vegetable variation, cause serious economic loss.
Ethyl pleocidin is novel plant source insecticides, English common name：Spinetoram, ethyl pleocidin is
Produce from many armfuls of bacterium (Saccharopolyspora spinosa) fermentations of unwrapping wire bacteria thorn sugar, be pleocidin (Spinasad)
Derived product, its mechanism of action be act on insecticide nerve in nAChR and r- aminobutyric acid receptors, cause
Make signal transmission reaction of the polypide to irritability or inhibition insensitive, normal neural activity is affected, until dead.
Celastrus angulatus belongs to the perennial liana of Celastraceae Celastrus, is distributed widely in the mound of China the Yellow River, the Yangtze river basin
Mound and mountain area.The root bark and peel of stem of Celastrus angulatus contains various strength insecticidal constituents, separates from root bark or seed reflect at present
Make dozens of noval chemical compound, particularly obtain 4 crystallizations from kind of oil, i.e. Celastrus angulatus ester I- IV, obtain from root bark 5 it is pure
Natural product, i.e. Celastrus angulatus I-V.The active insecticidal components of these Celastrus angulatus weights are referred to as Celastrus angulatus
(celastrusangulatus)。
Diamondback moth thereby results in diamondback moth and single medicament is resisted because its fertility is strong, life cycle is short, take place frequently throughout the year
Sexual development is very fast, and prevention effect is undesirable.It is to delay pest and disease damage to resist and the farm chemical ingredients for passing through different mechanism of action are compounded
The simply and easily approach of of property.It is used at present prevent and treat the pesticide of diamondback moth with ethyl pleocidin and Celastrus angulatus mixture
Mixture there is no report with application.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of Insecticidal combinations containing Celastrus angulatus and ethyl pleocidin
Thing, to solve frequently to cause pest resistance to insecticide aggravation, mu to use using ethyl pleocidin because single in the preventing and treating of diamondback moth
The practical problem of high cost.
The present invention is employed the following technical solutions：A kind of Pesticidal combination containing Celastrus angulatus and ethyl pleocidin, effectively
Composition is made up 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.
Described Pesticidal combination, ethyl pleocidin is 2-10% in the percentage by weight of compositionss, and Celastrus angulatus exist
Percentage by weight in compositionss is 0.5-2%.
