Description
Technical field
The invention belongs to compounded preparation of pesticide field, and in particular to a kind of compound sterilizing combination for preventing the late blight of potato
Thing；This first active material of complex preparation compound is benziothiazolinone, and the second active material is fluorine thiazole pyrrole ethyl ketone.
Background technology
Benziothiazolinone, is a kind of new, wide-spectrum bactericide, is mainly used for preventing and treats cucumber downy mildew, pear scab, apple
The various bacteria of fruit shot hole, citrus anthracnose, grapevine anthracnose etc., fungal disease.Its bactericidal effect mechanism, mainly includes
Germ nuclear structures are destroyed, make that it loses cardia and exhaustion is dead and the metabolism of interference germ cell, make its life
Reason is disorderly, ultimately results in dead two aspects.
Fluorine thiazole pyrrole ethyl ketone, is piperidyl thiazole isoxazoline series bactericidal agent；Fluorine thiazole pyrrole ethyl ketone is to Oomycete pathogen
With unique action site, bactericidal effect is reached by the suppression to oxidation steroid binding proteins (OSBP).It is to pathogen
With prevention, sporification is treated and inhibit, is had to the oomycetes diseases on potato, grape, vegetables and other special crops
There are excellent bactericidal activity, and efficacy stability；There is special efficacy to downy mildew and late blight, and can effectively prevent root rot and stem rot
Deng.The product can quickly be absorbed by wax coat, and there is outstanding resistance of rainwater washing against to act on, at the same be drawn in having top conduction,
The characteristics of protecting cambium.Foliar spray and seed treatment.
Fluorine thiazole pyrrole ethyl ketone is efficient, quick-acting, holding effect, its dosage is extremely low, is only the 1/5-1/100 of conventional sterilization agent.It is right
Pathogen each stage of development all has strong inhibition, can the long range transporting in host plant body, even in extremely disliking
Also can effective controlling disease under conditions of bad.Its dispenser is flexible, to crop safety.
The micro- poison of fluorine thiazole pyrrole ethyl ketone, has very favorable toxicology and environmental characteristics, to user, agricultural producer and ring
The security in border is higher.
Potato is that one kind in the extensive cereal crops of world wide cultivated area, the late blight of potato is potato planting
During Common Diseases, the harm phase is long, it is fast to propagate, and serious period often results in the crop significantly underproduction, seriously affect quality and
