Abstract
The invention belongs to the field of farm chemicals and discloses a bactericidal composition containing fluazinam and azoxystrobin and the application of the same. The fluazinam and the azoxystrobin serve as effective components of the composition, wherein the total content of the fluazinam and the azoxystrobin in mass percentage is 1% to 80%, and the mass ratio of the fluazinam to the azoxystrobin is 50:1 to 1:30. The composition can be used for the preparation of a bactericide 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 the agriculture chemicals fungicide field, relate to a kind of bactericidal composition and uses thereof, be specifically related to a kind of bactericidal composition and application thereof that contains fluazinam and Fluoxastrobin.
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.
Fluoxastrobin belongs to methoxy acrylic bactericide, have efficient, wide spectrum, nearly all mycota (Ascomycotina, Basidiomycotina, Mastigomycotina and Deuteromycotina) disease such as powdery mildew, rust, glume blight, net blotch, downy mildew, rice blast etc. are all had good activity.Can be used for cauline leaf spraying, seed treatment, be mainly used in crops such as cereal, paddy rice, peanut, grape, potato, fruit tree, vegetables, coffee, lawn, have good crop safety and very outstanding Environmental compatibility.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 Fluoxastrobin 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 Fluoxastrobin 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, with fluazinam and Fluoxastrobin is main active ingredient, wherein the gross mass percentage composition of fluazinam and Fluoxastrobin is 1%~80%, preferred 5%~60%, the mass ratio of fluazinam and Fluoxastrobin is 50: 1~1: 30, be preferably 30: 1~1: 20, preferred especially 20: 1~1: 10.
This bactericidal composition can become any one formulation that allows on the agricultural chemicals, the preferred suspending agent of described formulation, dry suspending agent, suspension seed-coating agent, wetting powder, pulvis, water dispersion granule, aqueous emulsion etc. with Fluoxastrobin by fluazinam with known additive compound.These known auxiliary agents are dispersant commonly used on the agricultural chemicals, diffusant, defoamer, wetting agent, disintegrant etc.
Bactericidal composition provided by the invention can be used for preparing the bactericide of preventing and treating corps diseases, be preferred for preparing the bactericide of the disease that control and cereal, vegetables or fruit tree crop cause by fungi and other pathogene, further be preferred for preparation control rice blast, banded sclerotial blight, wheat sharp eyespot, rust, powdery mildew of cucumber, downy mildew, tomato blight, grape powdery mildew, mango anthracnose, the bactericide of pear scab most preferably is used to prepare the bactericide of preventing and treating rice blast, powdery mildew of cucumber, mango anthracnose or pear scab.
Beneficial effect of the present invention:
1, the used fluazinam of the present invention is the pyridines bactericide, and Fluoxastrobin is a methoxy acrylic bactericide, and being mixed mutually can not produce conflict, can produce 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.
