Description
Technical field
The invention belongs to pesticide field, relate to a kind of broad spectrum activity bactericidal composition, be specifically related to bactericidal composition and the application thereof of a kind of containing fluazinam and Prochloraz.
Background technology
In recent years, due to fungi, bacterium, nematode, virus and the plant disease that causes such as malnutritive 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, being confined on the high some crops of economic value added of usable floor area used area less, can not use in the crop pests control widely, and this bactericide also exists the larger defective of toxicity.
Prochloraz (prochloraz) (or its manganese salt prochloraz-manganese chloride complex) is a kind of efficient, broad spectrum activity imidazoles bactericide and freshness preserving agent for fruit and vegetable, be used for cereal control pseudo-cercospora, nuclear cavity Pseudomonas, spore and belong to and the Septoria fungi, to early stage eye spot disease, leaf spot and powdery mildew, preventive effect is arranged.Be used for that oilseeds, grape can be prevented and treated Alternaria, Botrytis, pseudo-cercospora, bury Sclerotinia, the Sclerotinia fungi.Living Cercospora and Erysiphe on Ascochyta on the control leguminous plant, Botrytis, beet have preventive and therapeutic effect for the cochliobolus genus on cereal, Fusarium, nuclear cavity Pseudomonas, the fungus-caused disease of Septoria.In addition, can prevent and treat the cauliflower leaf spot, rice blast.Spraying general metering for fruit and vegetable before results is 20-50g/100L, uses the solution impregnation of 250-1000mg/L after results in case rot storage period.In addition, with 0.2g/ha dosage can 100% control cauliflower leaf spot, with the medicine liquid spray of 500ppm in the rice blast of effectively preventing and treating severe infections.General dosage is 12.5g/ mu when the anthracnose of the fruit such as control capsicum, lichee, banana.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 bactericidal composition of relevant fluazinam and Prochloraz.
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 Prochloraz are provided.
Another object of the present invention is to provide the application of said composition in the bactericide of preparation control corps diseases.
A kind of microbicide compositions contains fluazinam and Prochloraz, and wherein the mass ratio of fluazinam and Prochloraz is 30: 1～1: 20, is preferably 20: 1～1: 15.Wherein, the gross mass percentage composition of described fluazinam and Prochloraz is 10%～70%, preferred 15%～60%.
Described fluazinam and Prochloraz and known auxiliary agent and excipient are re-dubbed any one formulation that allows on agricultural chemicals.Can be processed into suspending agent, dry suspending agent, suspension seed-coating agent, wetting powder, pulvis, water dispersion granule, aqueous emulsion, microemulsion or missible oil etc. after two active component combinations.
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, vegetables or fruit tree crop disease, be particularly preferred for preparation control rice blast, banded sclerotial blight, wheat scab, the bactericide of powdery mildew of cucumber, downy mildew or citrus anthracnose etc., the most preferably bactericide of preparation control rice blast, powdery mildew of cucumber or citrus anthracnose.
Beneficial effect of the present invention:
1, the present invention's fluazinam used is the pyridines bactericide, and Prochloraz is the imidazoles bactericide, and mutually being mixed can not produce conflict, but Synergistic can reduce dosage when using, reduce costs.
2, 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.
