Abstract
The invention belongs to the field of farm chemicals and discloses a bactericidal composition containing fluazinam and validamycin and the application of the same. The fluazinam and the validamycin serve as effective components of the composition, wherein the total content of the fluazinam and the validamycin in mass percentage is 5% to 70%, and the mass ratio of the fluazinam to the validamycin is 50:1 to 1:30. The composition can be used for preventing and treating diseases such as rice blast, rice sheath blight, wheat leaf blight, wheat rust disease, peanut leaf spot, peanut net blotch, late blight of tomato and potato, gray mold, powdery mildew and anthracnose of cucumber, and apple scab caused by fungi and other pathogens of cereal crops, vegetable and fruit trees, and has the advantages of wide application range, low cost and good effect.
Description
Technical field
The invention belongs to pesticide field, relate to a kind of bactericidal composition and application thereof, be specifically related to bactericidal composition and the application thereof of a kind of containing fluazinam and jinggangmeisu.
Background technology
In recent years, because fungi, bacterium, nematode, virus and the plant disease that causes such as malnutritive are more and more heavy, the impact that causes is also increasing.
Fluazinam belongs to 2,6-dinitroanilines, is protective fungicide, is mitochondrial oxidation phosphorylated uncoupler.Suppress the course of infection in all stages by suppressing spore germination, mycelia breakthrough, growth and sporulation.The fungicidal spectrum of fluazinam is very wide, and its effect is better than the GPF (General Protection False bactericide.Interlink spore genus, Botrytis, Phytophthora, single shaft Pseudomonas, Sclerotinia and Venturia there are special efficacy, the Botrytis cinerea of anti-benzimidazole type and dicarboximide series bactericidal agent are belonged to good effect is also arranged.This medicine also has the effect that resistance of rainwater washing against, lasting period are long, have good control phytophagous mites concurrently in addition, and the club root of crucifer is also had remarkable preventive effect, and the microbial paddy rice damping off of friendly head mold is also had good control efficiency.
In China, because the fluazinam import price is high, usable floor area is confined on the high some crops of economic value added, uses area less, can not use in the crop pests control widely, and this bactericide also exists the larger defective of toxicity.
Jinggangmeisu is a kind of antibiotic of actinomycetes generation, has very strong interior suction bactericidal action, is easily absorbed by somatic cells and rapidly conduction within it, disturbs and inhibition somatic cells g and D.The crops such as suitable water paddy and wheat class, vegetables, ginseng, corn, beans, cotton and melon and fruit, to rice sheath blight disease, false smut, Wheat sheath blight, cotton, ginseng, beans and melon and fruit class damping off, corn northern and southern leaf blight has better effects.But under the condition of at present long-term single drug, the evil bacterium increases gradually to its pesticide resistance, and with other kinds series bactericidal agent cross resistance is arranged, and the agricultural chemicals single dose descends gradually to the effect of evil bacterium control.
Agriculture chemical compounding can obviously improve drug effect, and delays the generation of evil bacterium resistance.Not yet find up to now the Pesticidal combination of relevant fluazinam and jinggangmeisu.
Summary of the invention
The objective of the invention is for the problems referred to above, a kind of applied widely, containing fluazinam that cost is low, effective and the bactericidal composition of jinggangmeisu are provided.
Another object of the present invention provides this
A kind of microbicide compositions, take fluazinam and jinggangmeisu as active ingredient, wherein the mass ratio of fluazinam and jinggangmeisu is 50: 1～1: 30, preferred 30: 1～1: 20, particularly preferably 20: 1～1: 10.Wherein, the gross mass percentage composition of described fluazinam and jinggangmeisu is 5%～70%, preferred 10%～60%.
Described fluazinam and jinggangmeisu and known auxiliary agent and excipient are re-dubbed any one formulation that allows on the agricultural chemicals.Can be processed into suspending agent, dry suspending agent, wetting powder, pulvis, water dispersion granule etc. after the combination of two active components.
This bactericidal composition can be used for preparing the bactericide of preventing and treating corps diseases, be preferred for preparing the bactericide of control paddy rice, wheat, corn, cotton, vegetables or fruit crop disease, further be preferred for preparation and prevent and treat rice sheath blight disease, false smut, wheat sharp eyespot, cotton seedling blight, the bactericide of cucumber downy mildew, powdery mildew or tomato blight, the particularly preferably bactericide of preparation control cucumber downy mildew, powdery mildew or rice sheath blight disease.
Beneficial effect of the present invention: the used fluazinam of the present invention is the pyridines bactericide, and jinggangmeisu is the antibiotics bactericide, and mutually being mixed can not produce conflict, can produce significant synergistic function, can reduce dosage when using, and reduces cost.The present composition has enlarged fungicidal spectrum and has widened dispenser period, has better antibacterial and sterilization double effects, has overcome the deficiency of a certain composition of single use, has avoided plant disease to produce the risk of resistance.
