Abstract
The invention belongs to the field of farm chemicals and discloses a bactericidal composition containing fluazinam and thiophanate methyl and the application of the same. The fluazinam and the thiophanate methyl serve as effective components of the composition, wherein the total content of the fluazinam and the thiophanate methyl in mass percentage is 5% to 85%, and the mass ratio of the fluazinam to the thiophanate methyl is 30:1 to 1:50. The composition can be used for the preparation of a bactericide for preventing and treating diseases such as rice blast, rice sheath blight, wheat powdery mildew, wheat rust disease, leaf spot of peanut, powdery mildew and downy mildew of cucumber, tomato pestilence, apple scab, citrus scab and the like, 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 broad spectrum activity bactericidal composition, be specifically related to a kind of bactericidal composition that contains fluazinam and thiophanate-methyl.
Background technology
Fluazinam belongs to 2, and the 6-dinitroanilines is a protective fungicide, is mitochondria phosphorous oxide acidylate 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, the club root of crucifer is also had remarkable preventive effect, to by the microbial paddy rice damping off of head mold good control efficiency being arranged also.
In China, because fluazinam import price height, usable floor area is confined on the high part crops of economic value added, and it is less to use area, can not use in the crop pests control widely, and this bactericide also exists the bigger defective of toxicity.
Thiophanate-methyl belongs to wide spectrum, interior absorption benzimidazole germicide, has prevention and effect such as treatment, is converted into carbendazim in plant corpus earlier, disturbs the formation of spindle in the mitosis of bacterium again, and then influences cell division.The fungicidal spectrum of thiophanate-methyl is wide, has to top property conduction function, and multiple diseases is had prevention and therapeutic action, simultaneously tetranychid and pathogenic nematode is had inhibitory action.Crops such as suitable water paddy and wheat class, rape, cotton, sweet potato, vegetables, flowers, apple, pears, grape, peach and oranges and tangerines, to rice blast, banded sclerotial blight, gibberella zeaze petch of wheat and barley, wheat rust, powdery mildew, sclerotinia rot of colza, cucurbits powdery mildew, cladosporium leaf and fruit mould of tomato, fruit tree and flowers scab, powdery mildew, anthracnose, grape powdery mildew, corn size leaf spot, anthracnose of sorghum, loose kernel smut etc. has good preventive effect.But under the condition of at present long-term single drug, the evil bacterium increases gradually to its pesticide resistance, and with benzimidazole germicide cross resistance is arranged, and the agent of agricultural chemicals list 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.Still find no the Pesticidal combination that closes fluazinam and thiophanate-methyl up to now.
Summary of the invention
The objective of the invention is at the problems referred to above, a kind of applied widely, bactericidal composition that contains fluazinam and thiophanate-methyl that cost is low, effective is provided.
Another object of the present invention provides the application of this bactericidal composition in the bactericide of preparation control corps diseases.
Described microbicide compositions is main active ingredient with fluazinam and thiophanate-methyl, and wherein the mass ratio of fluazinam and thiophanate-methyl is 30: 1～1: 50, is preferably 20: 1～1: 30, is preferably 10: 1～1: 20 especially.Wherein, the gross mass percentage composition of described fluazinam and thiophanate-methyl is 5%～85%, is preferably 10%～75%.
In the bactericidal composition, described fluazinam and thiophanate-methyl and known auxiliary agent and excipient are re-dubbed any one formulation that allows on the agricultural chemicals, and described formulation is that these known auxiliary agents such as suspending agent, pulvis, dry suspending agent, suspension seed-coating agent, wetting powder, missible oil, water dispersion granule have dispersant, diffusant, defoamer, wetting agent, excipient, disintegrant etc.
Bactericidal composition of the present invention can be used in the bactericide of preparation control corps diseases.
Bactericidal composition of the present invention is preferably used in the bactericide of preparation control paddy rice, wheat, peanut, fruit and vegetables crop pest.
Bactericidal composition of the present invention is particularly preferably in preparation control rice blast, banded sclerotial blight, wheat leaf rot, rust, leaf spot of peanut, tomato blight, powdery mildew of cucumber, downy mildew, use in the bactericide of apple scab, citrus scab etc., preferably prevent and treat application in the bactericide of powdery mildew of cucumber and/or rice blast in preparation.。
Beneficial effect of the present invention: the used fluazinam of the present invention is the pyridines bactericide, and thiophanate-methyl is a benzimidazole germicide, and being mixed mutually can not produce conflict, but Synergistic can reduce dosage when using, reduce cost.The present composition has enlarged fungicidal spectrum and has widened dispenser period, has preferable 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.
