Description
Technical field
The present invention relates to disinfectant use in agriculture application field, the sterilization synergistic composition of more particularly to a kind of containing triflumizole.
Background technology
Mixed reagent is very universal in current plant disease chemical prevention, and the kind of composite bactericide is in agricultural chemicals
The considerable position of market share.Reasonable employment composite bactericide, can reach preventive effect more more preferable than bactericide single dose, so
And, and not all bactericide is suitable for compounding, nor gratifying result can be produced after the mixing of all medicaments.Current agriculture
Often occur blindly using with during medicine is mixed, misread medication, cause the phenomenon of the Irrational Use of Drugs such as poisoning, pollution.
Agriculture chemical compounding is using can also delay or overcome drug-fast generation.The genesis mechanism and the resistance to the action of a drug of resistance phenomena
Administer more complicated, compound drug is only to overcome one of drug-fast approach, if complex preparation formula immobilizes, it is impossible to
Rotation is used, and also induces the risk of multiresistance.
Mechanism of action identical is bactericide compounded, then the resistance to the action of a drug for contributing to drug-fast generation or reinforcing to produce.
Such as benomyl and thiophanate methyl, they play inhibitory action in plant to the metabolism of nucleic acid.The two composite reagents have
Drug-fast generation beneficial to pathogen to medicament, so general action mechanism identical medicament should not be compounded.
Some medicaments may improve toxicity in compounding, and part built agent causes confusion in selling market, blindly compound simultaneously
Add a large amount of organic solvents and negative influence etc. is produced to agricultural environment, the presence of these problems is required to research and develop high-quality compounding
Agent or pesticide synergistic agent are solved.
Chinese yam polysaccharide is the main active in Chinese yam.Chinese yam polysaccharide is main by mannose, xylose, arabinose, Portugal
Grape sugar and galactolipin composition.Research shows that Chinese yam is extracted through hot water, deproteinized, ethanol precipitation, SephadexG-100 are purified
Chinese yam polysaccharide, molecular weight is 8.1 × 10-4.Current people are concentrated mainly on following aspect for the research of Chinese yam polysaccharide：Blood drops
The functions such as sugar, tonifying middle-Jiao and Qi, stimulation or regulation immune system, and the research for its bacteria resistance function is also fewer.
At present, Chinese yam polysaccharide for fungi inhibitory action and Chinese yam polysaccharide for bactericide synergistic effect also not
Seeing has research open.
The content of the invention
The technical problem to be solved in the present invention is the sterilization synergistic composition for providing a kind of containing triflumizole, significantly improves fluorine
The activity of bacterium azoles, reduces chemical pesticide dosage, delays the resistance to the action of a drug of pathogen to produce.
The technical scheme that present invention solution above-mentioned technical problem is taken is as follows：
A kind of sterilization synergistic composition of containing triflumizole, is made up of Chinese yam polysaccharide and fluorine bacterium azoles, described Chinese yam polysaccharide and
The synergy weight ratio of fluorine bacterium azoles is 1:2-5.
Described sterilization synergistic composition is prepared into pesticidal preparations.
Described pesticidal preparations are used for the preventing and treating of rice blast.
The beneficial effect that the present invention possesses is：Chinese yam polysaccharide and fluorine bacterium azoles are compounded according to specific weight ratio, are had
Obvious synergistic function, the inhibitory action very little of Chinese yam polysaccharide for fungi in itself, its synergy mainly as fluorine bacterium azoles
Agent, can significantly improve inhibitory activity of the fluorine bacterium azoles to germ, the two mixture can also reduce the use of fluorine bacterium azoles, so as to reduce
Cost, reduces the residual of chemical agent.
Embodiment
Technical scheme and beneficial effect are described further with reference to specific embodiment, it is of the present invention
Percentage be mass percent.
One indoor joint toxicity measuring test
In order to illustrate synergistic effect of the Chinese yam polysaccharide for fluorine bacterium azoles, the present invention calculates co-toxicity coefficient using the abundant methods of Sun Yun
(CTC) mixed effect is evaluated.
Toxicity index TI (A)=(EC50 of standard agent A EC50 ÷ A agent) × 100
Toxicity index TI (B)=(EC50 of standard agent A EC50 ÷ B agent) × 100
Actual toxicity index ATI (AB)=(A EC50 ÷ AB EC50) × 100
Percentage+TI (B) × B percentages in mixture of theoretical toxicity index TTI (AB)=TI (the A) × A in mixture
Number
Co-toxicity coefficient (CTC)=[mixture surveys toxicity index (ATI) ÷ mixtures theoretical toxicity index (TTI)] × 100
Evaluation criterion is：Co-toxicity coefficient >=120 show as synergistic effect；Co-toxicity coefficient≤80 show as antagonism；80<
Co-toxicity coefficient<120 show as summation action.
Test method：Reference《The part of NY/T1156.8-2007 farm-chemical indoor determination test rules bactericide the 8th：It is anti-
Control rice blast experiment pot-culture method》With《The 6th, NY/T1156.6-2006 farm-chemical indoor determination test rules bactericide
Point：The synergy of mixture is determined》.
The measurement result of fraction is as shown in the table：
As can be known from the above table, fluorine bacterium azoles and the weight of Chinese yam polysaccharide ratio are 2-5:When 1, its co-toxicity coefficient is all higher than 120, performance
Go out obvious synergistic function；Other ratios show simple summation action or obvious antagonism.
Two crop field test examples
In order to further illustrate beneficial effects of the present invention, applicant has also carried out multiple field medicine effect test.Below
The field experiment of part rice blast is enumerated as explanation.
Test medicine：
