Abstract
The invention discloses a pyrimidine nucleoside antibiotic and hexaconazole compound bactericide, which belongs to the technical field of agricultural agents. The bactericide is characterized by comprising 0.1 to 50 percent of pyrimidine nucleoside antibiotic and 0.1 to 70 percent of hexaconazole. By compounding the pyrimidine nucleoside antibiotic and the hexaconazole, the bactericide has good preventing and controlling effect, and the preventing and controlling rate of the bactericide can reach over 97 percent through field test; the bactericide has strong persistence, and the preventing and controlling rate of the bactericide can reach over 92 percent in 14 days after preventing and controlling banded sclerotial blight of rice and wheat; and the production cost is low and is reduced by over 50 percent compared with singly used pyrimidine nucleoside antibiotic.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of antibiotic in pyrimidine nucleoside class and own azoles alcohol composite bactericide that can be used for preventing and treating crop pests such as rice sheath blight disease, 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.
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.
Antibiotic in pyrimidine nucleoside class is pesticide corrosion 120 again, is a kind of alkaline Nucleoside Agricultural Antibiotics, and its sterilizing mechanisms is directly hinder phytopathogen protein synthetic, causes germ death.Based on the prevention protective effect, have certain therapeutic action concurrently.Can be used for preventing and treating the disease such as powdery mildew, black spot, rust, eqpidemic disease, fusarium wilt, anthracnose, banded sclerotial blight of crops such as melon, tobacco, fruit tree, flowers, Chinese cabbage, tomato, watermelon, paddy rice, wheat.To the people, animal low toxicity, noresidue, free from environmental pollution, to crop and natural enemies security, and the effect that stimulates plant growing is arranged.
A large amount of biological activity research show: own azoles alcohol has interior suction, protection and therapeutic activity; can prevent and treat disease due to sac fungi, basidiomycetes and the imperfect fungus effectively, especially disease that Basidiomycetes and Ascomycetes are caused such as powdery mildew, rust, scab, brown spot, anthracnose etc. have excellent protection and eradicant action.Rice sheath blight disease, wheat sharp eyespot there is good preventive effect.
Suitable crop and safety fruit tree such as apple, grape, banana, vegetables (melon and fruit, capsicum etc.), peanut, coffee, cereal crop and ornamental plants etc.Under recommended dose, use, to environment, crop safety.
Summary of the invention
At the problem that prior art exists, the objective of the invention is to design provide that a kind of lasting effect is long, control efficiency good, quick-acting fast and the pyridine ucleosides antibiotic of preventing and treating rice sheath blight disease, wheat sharp eyespot that cost is low and the technical scheme of own azoles alcohol composite bactericide.
