Abstract
The invention relates to a bactericide containing benzene kresoxim-methyl and validamycin A and used for the prevention and treatment of rice sheath blight disease and green smut, belonging to the technical field of agricultural chemicals. The bactericide containing benzene kresoxim-methyl and validamycin A contains the effective ingredients of benzene kresoxim-methyl and validamycin A, wherein the weight ratio of the benzene kresoxim-methyl and the validamycin A is 1:50-5:1. According to actual tests, the bactericide has outstanding prevention and treatment effect against rice sheath blight disease and green smut. Compared with conventional bactericides, the bactericide of the invention has the following advantages of: 1, obvious synergized action against rice sheath blight disease and green smut compared with single bactericide and being capable of remarkably enhancing the prevention and treatment effect; 2, being capable of replacing a part of medium/high-toxicity bactericides, lowering dose, reducing environmental pollution and residual quantity on agricultural products; 3, being capable of delay the resistance of rice sheath blight disease and green smut to single bactericide; and 4, long effecting period and lowered cost compared with single bactericide.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of bactericide that contains ZJ0712 and jinggangmycin A that can be used for preventing and treating rice sheath blight disease, false smut.
Background technology
Paddy rice is one of main cereal crops of China, banded sclerotial blight, false smut are main diseases of paddy rice middle and later periods, along with the large tracts of land of paddy rice light cultivation technology and high yield and high quality kind is promoted, growth period duration of rice, prolong, false smut the trend of increasing the weight of arranged, particularly many nitrogen fertilizer applications, the light green easier generation banded sclerotial blight of paddy rice of growth are injured the heaviest with high rice production area especially.Owing to lack the effective antigens material, do not breed at present the rice varieties of high anti-banded sclerotial blight, false smut as yet, for a long time, the pesticide species of control mainly relies on jinggangmeisu, but jinggangmeisu used more than 20 year, dosage constantly increases, especially the control number of times of rice sheath blight disease has used and be increased to present 3～4 times for 2 times the every year before 20 years, usage amount is increased to 4.5～6.0kg/hm2 from 1.5kg/hm2, control efficiency descends gradually, and the pesticide species of screening and development control paddy rice middle and later periods disease is imperative.
Summary of the invention
Technical problem to be solved by this invention provides a kind of bactericide that contains ZJ0712 and jinggangmycin A that rice sheath blight disease and false smut are had better control efficiency.
The present invention contains the bactericide of ZJ0712 and jinggangmycin A, and its active ingredient is ZJ0712 and jinggangmycin A, and wherein the weight ratio of ZJ0712 and jinggangmycin A is 1: 50-5: 1.
Also include auxiliary agent and carrier in the bactericide of the present invention, wherein ZJ0712 and jinggangmycin A account for the 5%-60% of bactericide gross weight, and auxiliary agent accounts for the 5%-30% of bactericide gross weight, and all the other are carrier.
Bactericide of the present invention can be water dispersible granules, wetting powder or aqueous emulsion.
Bactericide of the present invention has remarkable prevention effect through actual test to rice sheath blight disease and false smut.Compare with the conventional sterilization agent, it has the following advantages: 1, with single agent compare banded sclerotial blight, false smut has obvious synergistic effect, can significantly improve control efficiency; 2, can substitute high poisoning microbial inoculum in the part, reduce dosage, reduce the residual of environmental pollution and agricultural product; 3, can delay banded sclerotial blight, false smut pesticide resistance to single bactericide, 4, have long advantage of lasting period, compare with single medicament, can reduce cost.
