Description
Technical field
The present invention relates to pesticide technology preparation field, and in particular to a kind of disinfectant use in agriculture containing kasugarnycin and the gloomy copper of thiophene
And its application.
Background technology
It is known that plant is subject to the infringement of the microorganisms such as bacterium, fungi, virus, wherein fungi and bacteriosis is outstanding
Its is important, to plant growth, breed, store and transport threat it is very big.Preventing and treating the reactive compound of this kind of disease has thiazole acid amides
Class, triazole type, methoxy acrylate, imidazoles etc., but as a rule, their plant tolerance and resistance plant cause
The need for the activity of germ can not always meet agricultural production.Therefore be only extremely difficult to protect with a kind of reactive compound plant not by
Harmful levels of pathogens harm purpose, once resistance produce can promote user increase dosage so that can more accelerate the generation of resistance,
Cost increase, residues of pesticides and crop safety problem, the high compound of these activity and security are good, resistance generation is slow, wide spectrum
The problem of pharmacy mix of property then receives much concern as people.
The gloomy copper of thiophene be the applicant in the successful compound of development experiments (ZL00132657.0) in 2000, its single dose is
Largely used by agricultural, commodities market.
Chemical name：N, N '-methylene-bis- (thiadiazoles of 2- amino -5- sulfydryls 1,3,4) copper
The gloomy copper of thiophene is the organic copper fungicide of thiazoles, main registration prevent and treat bacterial blight of rice, bacterial stripe,Chinese cabbage
Soft rot and bacterial wilt of tomato.High-efficiency broad spectrum, toxicity is low, safety and environmental protection, nuisanceless, to bacterial disease special efficacy, to fungoid
Disease is effective.Particularly there is special efficacy to bacterial blight of rice and bacterial leaf streak of rice and c itrus canker.The gloomy copper of thiophene is to thin
Fungus diseases special efficacy, but prevent and treat fungal disease activity and be difficult to meet requirements at the higher level.
The content of the invention
The single shortcoming that medicament application surface is narrow and single drug financial cost is high is solved for more preferable and more economical property,
Drug effect can be improved simultaneously and reduces the resistance to the action of a drug of germ.It is an object of the invention to provide a kind of containing kasugarnycin and the gloomy copper of thiophene
Disinfectant use in agriculture and its application.
The technical solution used is invented in this practicality：A kind of disinfectant use in agriculture containing kasugarnycin and the gloomy copper of thiophene, institute
The mass fraction ratio that the disinfectant use in agriculture stated is included between kasugarnycin and the gloomy copper of thiophene, the described gloomy copper of kasugarnycin and thiophene is 1:
5-5∶1。
Mass fraction ratio between the described gloomy copper of kasugarnycin and thiophene is 1: 5 or 1: 1.
Described disinfectant use in agriculture also includes solvent, wetting agent, dispersant, thickener, antifreezing agent, preservative, disintegration
Agent, stabilizer, defoamer, colouring agent, filler and water.
A kind of application of disinfectant use in agriculture containing kasugarnycin and the gloomy copper of thiophene on preventing and treating citrus bacterial canker disease.
A kind of application of disinfectant use in agriculture containing kasugarnycin and the gloomy copper of thiophene on preventing and treating soft rot of Chinese cabbage.
The beneficial effects of the invention are as follows：The invention provides a kind of disinfectant use in agriculture containing kasugarnycin and the gloomy copper of thiophene and its
Using in the presence of extra fine quality ratio, there is relatively good synergistic function, have to citrus bacterial canker disease and soft rot of Chinese cabbage
Prevention effect, and bactericidal composition Synergistic of the present invention is substantially, it is efficient to bacterial disease to give full play to the gloomy copper of thiophene, expands
To fungal disease the characteristics of effective and its good protective value, and its activity and bactericidal effect are not the letters of each component activity
Single superposition, but have significant synergistic effect, slow down the generation of resistance, it is good to dispenser crop safety, meet pesticidal preparations
Security requirement.
Embodiment
The screening that kasugarnycin and the gloomy copper compounding of thiophene are formulated to citrus bacterial canker disease
Test target：Citrus bacterial canker disease
Reagent agent：
Test method：
With reference to bactericide agricultural chemicals indoor bioassay experiment criterion, turbidity method.
Test medicine：
The 70% kasugarnycin TC and gloomy copper TC of 95% thiophene is provided by Zhejiang east wind Chemical Co., Ltd., and kasugarnycin can be straight
Connect and be dissolved in water, the gloomy copper TC of 95% thiophene is made into 20%SC by our unit's formulation room.
Experiment process：
The gloomy copper SC (B) of 70% kasugarnycin TC (A), 20% thiophene and both and both five proportioning (A: B mass point
The ratio between number is 1: 5,1: 3,1: 1,3: 1,5: 1) be arranged to 200,100,50,25,12.5mg/L series concentrations.
Test method：
Citrus bacterial canker disease pathogen is rule on LB solid mediums, cultivated at 28 DEG C until growing single bacterium
Fall.The single bacterium colony of citrus bacterial canker disease pathogen above picking LB solid mediums, is put into the LB culture mediums of liquid, 28
DEG C, 200rpm constant-temperature tables shaken cultivation to OD600 values 0.5 or so, it is standby.
Test medicine A is configured to 200,100,50,25,12.5mg/L toxic LB fluid nutrient mediums 20ml, with same
Method by test medicine B and both five proportionings be configured to respectively concentration for 200,100,50,25,12.5mg/L contains
Malicious LB fluid nutrient mediums 20ml, adds the LB fluid nutrient mediums of the pathogens containing citrus bacterial canker disease of 500 μ 1, in 28 DEG C, 200rpm perseverances
The bacterium solution of each concentration is determined OD600 values by warm shaking table shaken cultivation to CK OD600 values 0.5 or so on spectrophotometer.
And it is 200,100,50,25,12.5mg/L medicaments and the toxic sterile LB fluid nutrient mediums of comparison medicament to determine concentration in addition
OD values are carried out, to being corrected due to the OD values that medicament is caused in itself.
Drug effect is calculated：
Correct the OD values=values of OD containing bacterium culture medium-aseptic culture medium OD values
Preventive effect %=(correction control medium OD values-correct toxic culture medium OD values)/correction control medium bacterium solution OD
Value * 100
The calculating of co-toxicity coefficient：
On the basis of medicament bacteriostasis rate, data analysis statistical is carried out with " DPS data handling systems " 3.11 professional versions, is asked
Go out regression straight line, EC50 coefficient correlations.The EC50 of the individual processing of measure is converted into actual poison exponent according to Sun Yun abundant methods
(ATI)；Matched according to mixture, calculate theoretical toxicity index (TTI), the co-toxicity coefficient (CTC) of mixture is calculated by following equation.
Content (the %)+B of mixed toxicity index (the TTI)=A of theory toxicity index × A in mixed toxicity index ×
Toxicity index × C contents (%) in mixed of the B in content (%)+C in mixed
If co-toxicity coefficient is more than 120, show there is synergistic effect；Between 100-120, summation action is shown to be；If substantially low
In 100 (less than 80), antagonism is shown to be.
Interpretation of result：
Five representational proportionings are taken using five-spot, and toxicity test is carried out to this 5 proportionings and standard agent.Knot
Fruit shows (table 1) that the gloomy copper B of kasugarnycin A, thiophene and 5 proportionings (A: B is 1: 5,1: 3,1: 1,3: 1,5: 1) of the two are to citrus
The EC50 of canker is respectively 36.70,41.37,33.22,41.30,39.99,34.68,31.74mg/L.
Analysis shows (table 2) are carried out to test result according to Sun Yun abundant co-toxicity coefficient calculating means.Kasugarnycin is gloomy with thiophene
The co-toxicity coefficient of copper compounding is between 97.08-121.95.Set proportioning A: B of experiment is to show as synergistic effect at 1: 5, remaining
Proportioning shows as summation action.
