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; On the other hand, the resistance of pathogen rises year by year under the medicament selection pressure continued, 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 containing Silthiopham and pyrrole metsulfovax providing a kind of applied widely, cost low, effective for above-mentioned technical problem.
A further object of the invention is to provide this bactericidal composition and causes application on fungal disease at control plant epiphyte, is is especially preventing and treating the purposes on the fungal diseases such as take-all, gray mold, powdery mildew.
The object of the invention is to be achieved through the following technical solutions:
A kind of bactericidal composition containing Silthiopham and pyrrole metsulfovax, this bactericidal composition with Silthiopham and pyrrole metsulfovax for principle active component, wherein the mass ratio of Silthiopham and pyrrole metsulfovax is 1 ~ 70:1 ~ 50, and wherein in bactericidal composition, effective ingredient is present in composition with enhancing effective amount.
Described bactericidal composition, wherein the mass ratio of Silthiopham and pyrrole metsulfovax is preferably 1 ~ 50:1 ~ 50, more preferably 1 ~ 30:1 ~ 20.
The preferred mass proportioning of Silthiopham and pyrrole metsulfovax also can be: 70:1,50:1,30:1,20:1,10:1,5:1,2.5:1,1:1,1:2,1:4,1:6,1:10,1:20,1:30,1:50.
In the compositions of the present invention, the mass percentage accounting for composition both Silthiopham and pyrrole metsulfovax is 2 ~ 80%.Preferably 5 ~ 70%.
Described bactericidal composition, wherein with Silthiopham and pyrrole metsulfovax for principle active component and known auxiliary agent and excipient are re-dubbed any one formulation that agricultural chemicals allows.These known auxiliary agents, excipients has dispersant, diffusant, defoamer, wetting agent, disintegrant etc., calcium dodecyl benzene sulfonate can be adopted, alkylphenol polyoxyethylene, Ben-zylphenol Polyoxyethyl Ether, phenethyl phenol polyethenoxy ether, fatty alcohol-polyoxyethylene ether and similar products thereof, aliphatic amine polyoxyethylene ether, fatty acid ethylene oxide addition product, the rare block compound of polyoxyethylene polyoxy third, castor oil polyoxyethylene ether, polyoxyethylene nonylphenol ether, TWEEN Series, fatty alcohol-polyoxyethylene ether, polyethylene glycol series, Sulfonates, carboxylate, sulphate, phosphate, phosphite, lignosulfonates, xanthans, phenol formaldehyde condensate, ammonium salt, one or more combinations in quaternary etc., excipient comprises cyclohexanone, dimethylbenzene, various solvent naphtha, water, antifreezing agent (as propane diols), deionized water etc.Above auxiliary agent, excipient and other auxiliary material can be alone or and use.
Described bactericidal composition, its formulation is missible oil, wetting powder, suspending agent, aqueous emulsion or water dispersion granule.
The application of above-mentioned bactericidal composition on preparation control fungal diseases of plants medicine.Especially in control Cereal, fruit tree, vegetable crop disease, application has remarkable result.
Above-mentioned application, described fungal diseases of plants is at least one in take-all, gray mold, powdery mildew.
The feature of bactericidal composition of the present invention:
1, the Silthiopham that the present invention is used and pyrrole metsulfovax, mutual mixture can not produce conflict, can Synergistic, reduces dosage, reduces costs.
2, the present composition scope of application increases, and be applicable to the refractory fungal disease of preventing and treating Cereal, fruit tree, vegetables, particularly preventing and treating take-all, gray mold, powdery mildew etc. all has significant effect.Bactericidal composition of the present invention has good control efficiency to sac fungi, basidiomycetes, imperfect fungus and Oomycete fungal disease; And suppress insect or fungi to the drug-fast generation of unitary agent (Silthiopham and pyrrole metsulfovax arbitrary).Bactericidal composition of the present invention can produce higher synergistic function, and the consumption of the independent reactive compound of the amount ratio of this mixture reduces greatly, and namely the activity of mixture is greater than the activity of independent component.
Compared with prior art beneficial effect of the present invention: (1) is compared with single dose, said composition antagonism fungal disease such as the fungal diseases such as take-all, gray mold, powdery mildew have obvious synergistic function, overcome and delayed pesticide resistance, expanding prevention is composed, and significantly improves control efficiency; (2) control recruitment, drug cost is reduced; (3) alternative routine and the easy agricultural chemicals producing resistance; (4) compared with single dose, produce and use cost reduction; (5) the drug-fast generation of Antifungi, its successful uses higher than its single dose.
Embodiment
Below in conjunction with embodiment, the invention will be further described, and in embodiment, the preparation method of formulation is conventional method, and " % " of the present invention is mass percent.
Indoor biometrics is tested:
In indoor employing mycelial growth rate method, measure different agents to the EC of bacterial strain
50value, adopt co-toxicity coefficient computational methods, calculate the co-toxicity coefficient (CTC) of mixture, determine the building performance of mixture, circular 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/ certain single dose EC
50× 100
Toxicity index × B single dose proportion in mixture 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 synergetic, and be antagonism when CTC is less than 80, CTC is summation action between 80-120.
According to active ingredient Silthiopham (A): pyrrole metsulfovax (B) quality proportioning is: 80:1,70:1,50:1,30:1,20:1,10:1,5:1,2.5:1,1:1,1:2,1:4,1:6,1:10,1:20,1:30,1:50,1:60 test, measure its co-toxicity coefficient to take-all germ (Gaeumannomycesgraminis (Sacc.) Arx.olivcr).
