Description
Technical field
The present invention relates to disinfectant use in agriculture application field, more particularly to a kind of sterilization synergistic composition containing cyazofamid.
Background technology
With the development and application of compound drug, the kind of compound drug is continuously increased, and complex preparation is in whole agricultural chemicals city
Proportion is occupied in maximum.The formulation of composite bactericide has had been applied to all formulations, such as wettable powder, aqua, missible oil,
Suspending agent, fumicants, seed coat agent, water dispersion granule etc..The compounding of people on one's own initiative by built agent between bactericide in production
It is expanded to the compounding with other medicaments.For example by the compounding of bactericide and insecticide, the simultaneous purpose controlled of disease pest is reached；By bactericide
It is also a focus with microbial source or botanical fungicide compounding；In addition, people are also using bactericide and plant growth element
Or synergist is compounded.
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 a kind of sterilization synergistic composition containing cyazofamid of offer, significantly improves cyanogen
The activity of white 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 containing cyazofamid, is made up of Chinese yam polysaccharide and cyazofamid, described Chinese yam polysaccharide and
The synergy weight ratio of cyazofamid is 1:5-8.
Described sterilization synergistic composition is prepared into pesticidal preparations and for preventing and treating rice blast.
The beneficial effect that the present invention possesses is：Chinese yam polysaccharide and cyazofamid 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 cyazofamid
Agent, can significantly improve inhibitory activity of the cyazofamid to germ, the two mixture can also reduce the use of cyazofamid, 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 cyazofamid, 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：
