Abstract
The present invention relates to a kind of bactericidal composition containing Chinese yam polysaccharide, active ingredient is made up of Chinese yam polysaccharide and Propineb, and the synergy weight ratio of Chinese yam polysaccharide and Propineb is 1:7‑10.The present invention is compounded Chinese yam polysaccharide and Propineb according to specific weight ratio, with obvious synergistic function, the inhibitory action very little of Chinese yam polysaccharide for fungi in itself, its synergist mainly as Propineb, inhibitory activity of the Propineb to germ can be significantly improved, the two mixture can also reduce the use of Propineb, so as to reduce cost, reduce the residual of chemical agent.
Description
Technical field
The present invention relates to disinfectant use in agriculture application field, more particularly to a kind of bactericidal composition containing Chinese yam polysaccharide.
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 bactericidal composition containing Chinese yam polysaccharide of offer, significantly improves third
The activity of gloomy zinc, 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 bactericidal composition containing Chinese yam polysaccharide, active ingredient is made up of Chinese yam polysaccharide and Propineb, Chinese yam polysaccharide
Synergy weight ratio with Propineb is 1:7-10.
The synergy weight ratio of described Chinese yam polysaccharide and Propineb is 1:10.
Described bactericidal composition is prepared into pesticidal preparations.
Described bactericidal composition is used to prevent and treat rice blast.
The beneficial effect that the present invention possesses is：Chinese yam polysaccharide and Propineb 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 Propineb
Agent, can significantly improve inhibitory activity of the Propineb to germ, the two mixture can also reduce the use of Propineb, 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 Propineb, 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, the weight ratio of Propineb and Chinese yam polysaccharide is 7-10:When 1, its co-toxicity coefficient is all higher than 120, table
Reveal obvious synergistic function；And when weight ratio is 1:1、2:1、3:1、4:1、6:1、11:1、13:1 and 14:When 1, its
Co-toxicity coefficient is less than 80, shows obvious antagonism；5:1 and 12:1 only shows simple summation action.
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：
The Chinese yam polysaccharide Propineb wettable powder (0.5 of test group 1 5.5%:5)
Chinese yam polysaccharide 0.5%, Propineb 5%, sodium carboxymethylcellulose 8%, alkylnaphthalene sulfonate 3%, precipitated calcium carbonate
2%, kaolin supplies 100%.Raw material weighing is carried out by above-mentioned formula, is crushed after being well mixed through airslide disintegrating mill, detection is closed
Lattice are that 5.5% Chinese yam polysaccharide Propineb wettable powder is made.
The Chinese yam polysaccharide wettable powder of control group 1 1%：Chinese yam polysaccharide 1%, sodium carboxymethylcellulose 8%, alkyl naphthalene sulfonic acid
Salt 3%, precipitated calcium carbonate 2%, kaolin supplies 100%.Preparation method is with test group 1.
The Propineb wettable powder of control group 2 5%：Propineb 5%, sodium carboxymethylcellulose 8%, alkylnaphthalene sulfonate

Separately set blank control group.
Test method and drug effect computational methods：Reference《GB/T 17980.19-2000 pesticide field efficacy medicine test criterions
(1) bactericidal agent for preventing and treating paddy rice leaf diseases》.Each plot area is 60 ㎡, 3 repetitions is set, altogether dispenser 2 times, between each dispenser
Every 7 days.
Investigation method：5 sampling surveys, the every company of taking are carried out in 7d, 15d after second of dispenser in each cell respectively
Continuous 3 clumps, look into whole blades, and classification record incidence, calculates disease index and preventive effect in units of blade；Test site：
Nanning.
Formula (1)：Disease index calculation formula：In formula (1)：X- disease indexs；Ni- disease at different levels
The number of sheets；I- is with respect to value of series；N- investigates total number of sheets.
Formula (2)：Prevention effect calculation formula：In formula (2)：P- prevention effects, unit
For percentage (%)；CK0Disease index before the dispenser of-blank district；CK1Disease index after the dispenser of-blank district；PT0- medicine
Disease index before agent treatment region dispenser；PT1Disease index after dispenser after-chemicals treatment.
As a result it is as shown in the table.
Prevent and treat the field control effectiveness test result of rice blast
As seen from the above table, the composition of the invention containing Chinese yam polysaccharide and Propineb is in the close control of active ingredient dosage
In the case of medicament, its prevention effect to rice blast is more significantly excellent than comparison medicament.The 7d investigation results after second of dispenser
It has been shown that, prevention effect of the invention is higher than Propineb single dose by 28.18%；15d investigation results are shown after second of dispenser, the present invention
Prevention effect it is higher than Propineb single dose by 21.73%.
