Abstract
The invention belongs to the field of farm chemicals and discloses a bactericidal composition containing fluazinam and cyprodinil and the application of the same. The fluazinam and the cyprodinil serve as effective components of the composition, wherein the mass ratio of the fluazinam to the cyprodinil is 40:1 to 1:30, and the total content of the fluazinam and the cyprodinil in mass percentage is 5% to 70%. The composition can be used for preventing and treating diseases such as rice blast, pestilence, anthracnose, leaf mold, scab and the like 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 broad spectrum activity bactericidal composition, be specifically related to a kind of bactericidal composition and application thereof that contains fluazinam and cyprodinil.
Background technology
It is many-sided that plant disease causes economic loss.At first, concerning the producer,, cause income to reduce because disease causes crop yield minimizing and product quality reduction; Owing to spraying insecticide or otherwise expenses for prevention and control increases production cost; Sometimes have to plant disease-resistant but kind that output is not high or replant the low crop species of other economic benefits; Influence preceding owing to results to the fruits and vegetables product or the duration of storage disease has to sell off at a low price when product goes on the market in a large number, or increases fresh-keeping expense for adjusting selling period.Secondly, concerning the consumer,, they have been increased live spending or minimizing consumption figure or buy substandard products or substitute, influenced quality of life because the disease underproduction causes agricultural product constantly to appreciate; For the intermediate consumer who comes other commodity of processing with agricultural product, agricultural product price goes up can be increased production cost or influence the end product quality, tends to the expense of increase is imputed on one's body the ultimate consumer as the producer's intermediate consumer.The 3rd, to the influence of national economy: estimate that according to FAO (Food and Agriculture Organization of the United Nation) average loss was about 10%～15% of gross yield after plant suffered disease.
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, 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 fluazinam import price height, being confined on the high part crops of economic value added of usable floor area, 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.
Cyprodinil belongs to the miazines bactericide, has protection, treatment, blade penetrates and the root systemic activity.Its mechanism of action is to suppress the biosynthesis of secretion of fungi hydrolase and methionine.Bactericide such as same triazole type, imidazoles, morpholine class, benzopyrrole class do not have cross resistance.Crops such as suitable wheat, barley, grape, strawberry, fruit tree, vegetables, ornamental plants have better control efficiency to gray mold, powdery mildew, scab, net blotch, glume blight and eyeprint disease.But under the condition of present long-term prescription, evil bacterium pesticide resistance increases gradually, 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 bactericidal composition that closes fluazinam and cyprodinil 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 cyprodinil that cost is low, effective is provided.
Another object of the present invention provides the application of said composition in the bactericide of preparation control corps diseases.
A kind of microbicide compositions is characterized in that containing fluazinam and cyprodinil, and wherein the mass ratio of fluazinam and cyprodinil is 40: 1～1: 30, and preferred 30: 1～1: 15, preferred especially 20: 1～1: 10.
The gross mass percentage composition of fluazinam and cyprodinil is 5%～70% in the described bactericidal composition, preferred 10%～60%.
Described bactericidal composition is that active ingredient can become any one formulation that allows on the agricultural chemicals with known additive compound with fluazinam and cyprodinil, and described formulation is suspending agent, dry suspending agent, suspension seed-coating agent, wetting powder, pulvis, aqueous emulsion, water dispersion granule, microemulsion or missible oil etc.These known auxiliary agents, excipient have dispersant, diffusant, defoamer, wetting agent, disintegrant etc., are the common auxiliary material in this area.
The bactericidal composition that the present invention relates to can be prevented and treated the bactericide of corps diseases with preparation, be preferred for preparation control cereal class, paddy rice, soybean, various melons and fruits, the bactericide of crop fungal disease such as vegetables and other pathogene diseases, further be preferred for preparation control rice blast, banded sclerotial blight, the wheat leaf rot, rust, gray mold, powdery mildew, leaf spot of peanut, net blotch, tomato, potato late blight, gray mold of cucumber, powdery mildew, anthracnose, apple scab, shot hole, grape powdery mildew, or the bactericide of pear scab etc., be particularly preferred for preparation and prevent and treat rice sheath blight disease, the bactericide of powdery mildew of cucumber or pear scab.
Beneficial effect of the present invention:
1, the used fluazinam of the present invention is the pyridines bactericide, and cyprodinil is the miazines bactericide, and being mixed mutually can not produce conflict, produces obvious role in synergism, can reduce dosage when using, and reduces cost.
2, 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.
