Abstract
The invention relates to a synergistic bactericidal composition and belongs to the technical field of complex pesticides. According to the synergistic bactericidal composition provided by the invention, fluxapyroxad and octyl bacterial amine are taken as main active ingredients to be compounded with known additives and excipients to form any allowable form, such as water dispersible granules, wet seed dressing agents, emulsifiable concentrate, wettable powder, suspension concentrate, oil formulation, suspoemulsion, coating agents of suspension concentrate, emulsion in water or microemulsion. The synergistic bactericidal composition provided by the invention has a significant effect when being applied to the preparation of medicaments for controlling resistant plant fungal diseases of cereals, fruit tress, vegetables and other crops, when being applied to the preparation of bactericidal medicaments for controlling powdery mildew, gray mold, sclerotiose, rot, rust, glume blight, net blotch, downy mildew, rice blast and sheath blight, and particularly when being applied to the preparation of bactericidal medicaments for controlling rice blast and powdery mildew of cucumbers.
Description
Technical field
The invention belongs to technical field of compounded pesticide, relate to a kind of bactericidal composition.
Background technology
Fluorine azoles bacterium acid amides is pyrazole amide series bactericidal agent, and be succinate dehydrogenase inhibitors, control is had both.The respiration of its energy Antifungi, suppress spore-germination, germ tube extends, mycelial growth and sporulation.Can be used for the multiple fungal disease controlling and suppress in various crop.But alone fluorine azoles bacterium acid amides single dose is relatively high in current use cost.
Pungent bacterium amine is obtained the modes such as cell membrane, coagulated protein, prevention breathing and ferment activity and reaches sterilization (virus) by all kinds of pathogene of destruction.This medicine has certain interior suction and osmosis, kills significantly and inhibitory action causing the various plants fungi of crop pest, bacterium and virus all to have.Because alone pungent bacterium amine is longer in the time limit that Main Rice Diseases is prevented and treated, the pesticide resistance of crop pest has had significant enhancing.
The difficulty of prevention and cure of current phytopathogen is increasing, and on the one hand, along with the change of pattern of farming, the economic crops such as melon and fruit, vegetables cultivated area progressively expands, and disease occurrence degree, generation quantity all increase, and in control, difficulty strengthens; Add on the one hand, the resistance of pathogen rises year by year under the medicament continued selects agent selection pressure, and the control efficiency of single dose is had a greatly reduced quality, and control of plant disease is faced with significant challenge.
Summary of the invention
The object of the invention is the plant bactericidal composition that a kind of applied widely, fluorine-containing azoles bacterium acid amides that cost is low, effective and pungent bacterium amine are provided for above-mentioned technical problem.
The present invention is with fluorine azoles bacterium acid amides and pungent bacterium amine for principle active component, and wherein the mass ratio of fluorine azoles bacterium acid amides and pungent bacterium amine is 1 ~ 90:1 ~ 90.
The present invention with fluorine azoles bacterium acid amides and pungent bacterium amine for principle active component and known auxiliary agent and excipient are re-dubbed any one formulation that agricultural chemicals allows, as water dispersible granules, wet seed dressing, missible oil, wetting powder, suspending agent, oil suspending agent, suspension emulsion, the agent of suspending agent clothing, aqueous emulsion or microemulsion.The present invention can prepare the application on the medicine preventing and treating Cereal, fruit tree, vegetable crop resistance plant fungal disease, preparing the application prevented and treated on the germ killing drugs of powdery mildew, gray mold, stalk break, rot, rust, Ying's rot, net blotch, downy mildew, rice blast and damping off, the application especially on the germ killing drugs preparing control rice blast and powdery mildew of cucumber has significant effect.
Beneficial effect of the present invention:
1, compared with single dose, the present composition scope of application increases, expanding prevention is composed, to sac fungi, basidiomycetes, imperfect fungus and print Gammaproteobacteria fungal disease, there is good control efficiency, especially antagonism fungal disease has obvious synergistic function as fungal diseases such as powdery mildew, gray mold, stalk break, rot, rust, Ying's rot, net blotch, downy mildew, rice blast, damping offs, significantly improves control efficiency.
2, compared with single dose, the activity of mixture is greater than the activity of independent component, reduces production and use cost, decreases control recruitment, medication one-tenth; (3) suppress insect or fungi to the drug-fast generation of unitary agent (fluorine azoles bacterium acid amides and pungent bacterium amine arbitrary), its successful uses higher than its single dose, overcomes and has delayed pesticide resistance, alternative routine and easily produce the agricultural chemicals of antibiosis.
Further, fluorine azoles bacterium acid amides of the present invention is 5 ~ 70:5 ~ 80 with the important ratio of pungent bacterium amine.
More preferably, described fluorine azoles bacterium amine and the important ratio of pungent bacterium amine are 5 ~ 50:5 ~ 40.
In addition, the gross mass of preferred fluorine azoles bacterium acid amides and pungent bacterium amine accounts for 2 ~ 90% of composition.
Further, the gross mass of fluorine azoles bacterium acid amides and pungent bacterium amine accounts for 15 ~ 80% of composition.
