Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of alkene oxime amine and validamycin compound germicide that can be used for preventing and treating crop pests such as rice sheath blight disease, rice green smut, wheat sharp eyespot.
Background technology
Rice sheath blight disease is the important disease of the normal property sent out on the paddy rice, on the south the Changjiang river rice district take place serious, thereby it is withered to make that with hazard rice blade, leaf sheath blade is done sth. in advance yellow, the paddy rice functional leaf be injured the back paddy rice can not normally ear from, cause ripening rate and thousand kernel weight to descend, thereby influence rice yield.Rice sheath blight disease all can be fallen ill in whole growth period duration of rice, and is the heaviest with morbidity in 7～September in the Yangtze river basin.The control of China's rice sheath blight disease uses mainly that jinggangmeisu, triazolone, standing grain fringe are peaceful, rice Feng Ling etc. is in premorbid or their early stage spraying control.But single is that control efficiency is bad with the common defective of this series bactericidal agent when preventing and treating rice sheath blight disease, also less stable.All can take place because rice sheath blight disease needs only temperature in rice plant of tillering stage to the maturing stage of earing, humidity is suitable, emergence period is long, and the control efficiency of control medicament is also not ideal, so needs repeatedly, dosage sprays medicine, to keep the control effect to rice sheath blight disease.Increased peasant's production cost like this, also strengthened, also agricultural product quality has been constituted considerable influence simultaneously environmental influence.
Rice green smut claims pseudo-smut, green smut, paddy blossom disease, blue or green powder disease, is commonly called as " high yield fruit ".This disease only betides fringe portion, the part that causes harm grain.The interior mycelia piece that forms of the grain of being injured gradually expands, interior coetonium splitting exposed faint yellow block, i.e. the spore seat, after be wrapped in coetonium both sides, be blackish green, first outsourcing thin film, after break, scattered blackish green powder, be the chlamydospore of germ, the flat sclerotium of two adnation black that has, exposing to wind and rain easily comes off.Hebei, the Yangtze river basin and rice district, southern each province happen occasionally.Be the main disease of paddy rice fringe phase in recent years, cause paddy rice ripening rate, thousand kernel weight obviously to descend, output significantly reduces.More important is that quality of rice, person poultry safety, natural environment have been caused great harm.Prevent and treat method: usually soaked seed 3～5 hours with 2% formalin or 0.5% copper sulphate, vexed then kind 12 hours is used flushing with clean water vernalization.The heading before with the ketone of bacterium more than 18% pulvis 150～200g or in paddy rice booting every 667m2 in latter stage with 14% network ammonia copper aqua 250g rice Feng Ling 200g or 5% jinggangmeisu aqua 100g, water 50L is sprayed.But single is that control efficiency is bad with the common defective of this series bactericidal agent when preventing and treating rice green smut, also less stable.
Wheat sharp eyespot has become China's wheat district regular incidence evil in recent years.After wheat was infected by the withered bacterium of line, symptoms such as mashed bud, the mashed stem of withered, the colored stalk of sick seedling, withered strain dead ears appearred at each growing stage.Mashed bud bud scale brown stain, back bud is withered to rot, and can not be unearthed; Sick seedling is withered to occur in for 3～4 leaf phases, first existing Intermediate grey on first leaf sheath only, and the scab of brown all around, the back is withered because of can not taking out the young leaves seedling that causes a disease; On the base portion leaf sheath, form Intermediate grey behind the mashed stem jointing of flower stalk, edge beige moire shape scab, after scab merged, basal part of stem was moire flower stalk shape; After withered strain dead ears scab is invaded the stem wall, taupe in the middle of forming, the subcircular of brown or oval eye spot cause stem wall dehydration necrosis all around, and that supply falls short of demand is withered because of nutrient, moisture for last diseased plant, forms withered strain dead ears.In addition, sometimes should disease also can form disease and invade the unconspicuous brown scab that has a common boundary.In recent years, because the change of kind, cropping system, fertilizer and water condition, disease increases the weight of year by year, and the lesion constantly enlarges from south to north.The morbidity underproduction 20～40% early, withered strain dead ears of serious formation or No kernels or seeds are gathered, as in a year of scarcity.The control of China's wheat sharp eyespot is mainly used jinggangmeisu, triazolone, Triadimenol etc. in premorbid or their early stage spraying control.But single is that control efficiency is bad with the common defective of this series bactericidal agent when preventing and treating wheat sharp eyespot, also less stable.
Jinggangmeisu claims valida again, belongs to the low toxicity bactericide.The big mouse acute oral of pure product LD50 is all greater than 2000 milligrams/kilogram, and hypodermic injection LD50 is all greater than 1500 milligrams/kilogram.Smear rat skin for 5000 milligrams/kilogram and do not have toxic reaction.To the fish low toxicity, carp TLM (96h) LD50＞40 mg/litre.Formulation has 5%, 10% aqua and 5%, 20%, 28% water solube powder.It is a kind of antibiotic of actinomycetes generation, has stronger interior absorption, is easily absorbed by somatic cells and conduction rapidly within it, disturbs and inhibition somatic cells g and D.Be mainly used in rice sheath blight disease, wheat sharp eyespot also can be used for the control of crop pests such as rice green smut and vegetables and cotton, and shortcoming is that the lasting period is short generally at 10～15 days.
A large amount of biological activity research show: the alkene oxime amine fungicidal spectrum is wide, activity is high, have prevention and therapeutic action, with environmental organism good compatibility is arranged, the plurality of plant diseases that is caused by mastigomycetes, zygomycete, sac fungi, basidiomycetes and imperfect fungus there is good control efficiency, to powdery mildew, rust control efficiency brilliance.Can be used for preventing and treating plurality of plant diseases such as wheat rust, wheat powdery mildew, rice sheath blight disease, false smut, powdery mildew of cucumber, cucumber downy mildew, downy mildew of garpe, alternaria leaf spot of apple, apple mildew, sigatoka, early blight of tomato, pear scab, powdery mildew of strawberry, rust of sunflower.Simultaneously, plant growth proterties and quality are improved significantly, and can improve output.But the alkene oxime amine price comparison is expensive, the use cost height.
