Abstract
The invention provides a synergistic bactericidal composition containing fluxapyroxad and isoprothiolane and belongs to the technical field of compound pesticides. According to the synergistic bactericidal composition, fluxapyroxad and isoprothiolane are taken as major active ingredients and compounded with known auxiliaries and an excipient into a pesticide in any allowable form; the synergistic bactericidal composition can be applied to preparing pesticides for preventing and treating resistant fungal diseases of cereal, fruit trees and vegetable crops; the application range of the synergistic bactericidal composition is widened and the prevention and treatment spectrum of the synergistic bactericidal composition is expanded; the synergistic bactericidal composition has excellent prevention and treatment effects on fungal diseases of ascomycetes, basidiomycetes, imperfect fungi and oomycetes, and especially has an obvious synergistic effect on resistant fungal diseases such as powdery mildew, gray mold, stalk break, rot, rust, glume blight, net blotch, downy mildew, rice blast and damping off, and therefore, the prevention and treatment effects are obviously improved. The activity of the synergistic bactericidal composition is greater than that of a single active ingredient; besides, the production and use costs are reduced, and the labor and pesticide costs for prevention and treatment are reduced.
Description
Technical field
The invention belongs to technical field of compounded pesticide, relate to the production technology 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.
Isoprothiolane is efficient, low toxicity, low-residual organosulfureous fungicide, for preventing and treating paddy rice rice neck pest, rice leaf pest, rice seedling pest etc.Being a kind of efficient systemic fungicide, is the special effect agent of control rice blast.Have preventive and therapeutic action to rice blast, by each site absorption of paddy rice, and can be accumulated to leaf portion tissue, thus play drug effect, resistance of rainwater washing against also doublely can control plant hopper.Main control rice blast, has certain preventive effect to rice sheath blight disease, culm rot and bacterial leaf-blight simultaneously.Because alone Isoprothiolane 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 Isoprothiolane are provided for above-mentioned technical problem.
The present invention is with fluorine azoles bacterium acid amides and Isoprothiolane for principle active component, and wherein fluorine azoles bacterium acid amides is 1 ~ 90:90 ~ 1 with the important ratio of Isoprothiolane.
The present invention with fluorine azoles bacterium acid amides and Isoprothiolane for principle active component and known auxiliary agent and excipient are re-dubbed any sharp 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, the 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.Activity of the present invention is greater than the activity of independent active ingredient, reduces production and use cost, decreases control recruitment, medication one-tenth.The present invention also suppresses insect or fungi to the drug-fast generation of unitary agent (fluorine azoles bacterium acid amides and Isoprothiolane arbitrary), and 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 ~ 70:80 ~ 5 with the important ratio of Isoprothiolane.
The important ratio of preferred fluorine azoles bacterium amine and Isoprothiolane is 5 ~ 50:40 ~ 5.
In addition, the gross mass that fluorine azoles bacterium acid amides and Isoprothiolane add up to accounts for 2 ~ 90% of composition gross mass, and preferably 15 ~ 80%.

50value, adopts co-toxicity coefficient computational methods, calculates the co-toxicity coefficient (CTC) of mixture, determine the building performance of mixture, and concrete calculating side is as follows:
With single dose a certain in mixture for standard agent (selects EC usually
50junior), calculate:
Single dose toxicity index=standard agent EC
50× 100.
Proportion in the mixture of the toxicity index × B single dose of toxicity index × A single dose proportion+B single dose in mixture of theoretical toxicity index=A single dose.
The EC of actual measurement toxicity index=standard single dose
50the EC of value/mixture
50value × 100.
Co-toxicity coefficient=actual measurement toxicity index/theoretical toxicity index × 100;
When co-toxicity coefficient classification: CTC is greater than 120, mixture has Synergistic bamboo, and be antagonism when CTC is less than 80, CTC is summation action between 80-120.
