Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of insecticide preventing and treating purple willow caterpillar.
Background technology
Purple willow is a kind of important economic crops of Basin of Huaihe River, main as wicker plaiting article raw material, but in purple willow process of growth, caterpillar is a kind of very harmful insect, and willow caterpillar is commonly called as golden caterpillar, malicious caterpillar.There is generation in willow field, various places more.Poisonous hair on larva body, can cause human body congestion and swelling pain.Based on larva harm, be one of Major Pests of purple willow, willow caterpillar focuses mostly on and takes food mesophyll at leaf back, and blade face is block speculum, and adult has phototaxis, lays eggs at leaf back, after 5 ~ 7 decortications, ties thin cocoon and pupate in bar pier or willow leaf.Worm's ovum focuses mostly at vacuum side of blade, in yellow; Before 3 ages, multigroup gathers together, and extracts worm leaf in time, can alleviate harm, but under efficiency.Medical treatment can with 80% ddvp emulsion, 1000 times of liquid, or 50% Phoxim emulsion, 3000 times of liquid spray, and cannot prevent, and medicament residue are serious.
Summary of the invention
The object of this invention is to provide a kind of insecticide preventing and treating purple willow caterpillar, by traditional Chinese medicine ingredients and chemical agent with the use of, greatly reduce the amount of application of chemical agent, and improve the control efficiency of caterpillar.
The present invention is achieved through the following technical solutions:
Prevent and treat an insecticide for purple willow caterpillar, be prepared from by following component by weight: ether chrysanthemum ester 2 parts, 2 parts, chlorophos, asiatic moonseed 2.6 parts, Piper longum 3.7 parts, vomiting nut 4.2 parts, wrinkled giant hyssop 5 parts, reticulate millettia 1.6 parts, sealwort 7 parts, radix glehniae 2.8 parts, tarragon 4 parts, 2.6 parts, saltcake, 1 part, tobacco leaf, the tuber of stemona 4 parts, frutus cnidii 4.2 parts.
Preferably, Chinese medicinal ingredients uses the soak by water of Chinese medicine weight 5 times respectively, obtains decoction liquor, decoction liquor is mixed, and then mixes with ether chrysanthemum ester, chlorophos, obtains insecticide.
Preferably, when using, insecticide and water are used after 1:300 dilutes.
Beneficial effect of the present invention: the present invention is by being combined Chinese medicinal ingredients with chemical agent, due to Chinese medicinal ingredients boiling, then mix with ether chrysanthemum ester and chlorophos, because the original content of chemical agent is lower, chemical agent is carried out further dilution, to again dilute during use, the content spraying rear unit are chemical agent is reduced greatly, the pesticide resistance of insect can not be caused, environmentally safe, simultaneously due to Chinese medicinal ingredients and the composite synergy of chemical agent, both can tag, there is again the effect of stomach toxicity, improve the control efficiency to caterpillar, and due to the concentration of chemical bactericide extremely low, can be decomposed by purple willow and absorb, can not produce residual, and medicine can kill worm's ovum, stop caterpillar breeding.
