Abstract
The present invention discloses a thiodiazole copper-tebuconazole compound pesticide, wherein the technical scheme is that a mass ratio of the thiodiazole copper to the tebuconazole is (1:8)-(8:1), the total concentration is 1.25-20 mg/L, and the solvent is water. According to the present invention, the thiodiazole copper-tebuconazole compound pesticide has the following beneficial effects that: the problem of the decreased prevention and control effect caused by drug resistance of rice sheath blight and the like is effectively overcome, and the embodiment experiment results verify that the thiodiazole copper and the tebuconazole provide the significant additive effect at the cotoxicity coefficient so as to provide the good prevention and control effect.
Description
Technical field
The present invention relates to a kind of Recompounded pesticide, specifically refer to a kind of Thiodiazole-copper Tebuconazole Recompounded pesticide.
Background technology
Rice sheath blight disease is also known as moire disease, and popular name spends sufficient stalk, rotten pin pest, features spot.Be by Rhizoctonia solani Kuhn (
fungi) infect and fall ill, how to occur under high temperature, super-humid conditions.Banded sclerotial blight causes harm seriously in South Rice Region of China, is one of Major Diseases in current Rice Production.This disease makes paddy rice not ear, or the not plump paddy of heading is more, and grain heavily declines.
Tebuconazole (Tebuconazole), chemical name: (RS)-1-(4-chlorphenyl)-4,4-dimethyl-3-(1H-1,2,4 triazol-1-yl methyl) penta-3-alcohol, its chemical structural formula is:
Tebuconazole is a kind of efficient, wide spectrum, interior absorption triazole type sterilization pesticide, and it is better to fungus disease control efficiency, but, along with this agricultural chemicals Long-Time Service, rice sheath blight disease germ very easily develops immunity to drugs to this medicine, and drug effect is very poor, and after morbidity, the state of an illness can not get effective control.
Thiodiazole-copper (thiodiazole-copper), its empirical formula is C4H4N6S4Cu, and chemical name is: 2-amino-5-sulfydryl-1,3,4-thiadiazoles copper, and its chemical structural formula is:
Thiodiazole-copper has outstanding control efficiency to bacterial diseases of crops, but for the banded sclerotial blight by fungus-caused paddy rice, its control efficiency is not very desirable.
Summary of the invention
The object of the invention is the shortcoming and defect existed to overcome prior art, and a kind of fungal diseases such as the banded sclerotial blight of control paddy rice that simultaneously have are provided, and the Thiodiazole-copper Tebuconazole Recompounded pesticide that control efficiency is good.
For achieving the above object, technical scheme of the present invention is the mass ratio of Thiodiazole-copper and Tebuconazole is (1:8)-(8:1), and total concentration is: 1.25-20mg/L, and solvent is water.
As the optimum choice of above-mentioned formula, described Thiodiazole-copper and the mass ratio of Tebuconazole are 8:1 or 4:1 or 1:1 or 1:4 or 1:8.
The beneficial effect of Thiodiazole-copper Tebuconazole Recompounded pesticide of the present invention is: the problem effectively overcoming the control efficiency decline that rice sheath blight disease germ etc. is caused because of resistance problems, by embodiment experimental verification, there is obvious additive effect in Thiodiazole-copper and Tebuconazole, obtain extraordinary control efficiency on co-toxicity coefficient.
Below in conjunction with embodiment, the present invention is described further.
Embodiment
Below by embodiment, the present invention is specifically described; only be used to further illustrate the present invention; can not be interpreted as limiting the scope of the present invention, the technician in this field can make some nonessential improvement and adjustment according to the content of foregoing invention to the present invention.
toxicity test experimental example
Sample target: Rhizoctonia solani Kuhn (Rhizoctonia solani)
Virulence method of testing: mycelial growth rate method
test process
Thiodiazole-copper (being numbered A), Tebuconazole (being numbered B) and 5 the quality proportioning A:B of the two are: 8:1,4:1,1:1,1:4,1:8.Thiodiazole-copper A is set to 200,100,50,25,12.5mg/L.Tebuconazole B establishes 5,2.5,1.25,0.625,0.3125 mg/L, and both five proportionings all arrange 5 concentration 20,10,5,5,2.5,1.25 mg/L, and each concentration establishes 4 repetitions, separately sets clear water as blank.
test method
Thiodiazole-copper A is made into 2000,1000,500,125 mg/L series concentration, the conical flask of 5 ml to sterilizing is drawn respectively in superclean bench, add the PDA medium 45ml of about 50 DEG C, after shaking up, pour the plate of 4 diameter 9 cm into, make the toxic medium of 4 respective concentration; Using the same method Tebuconazole B and both 5 proportioning A:B is that 8:1,4:1,1:1, l:4,1:8 make default series concentration respectively.By the cultivation rice banded sclerotial blight cause of disease bacterium of 3 days, break into bacterium block with the card punch of diameter 5 mm at colony edge, with transfer needle, bacterium block is moved to the toxic PDA medium central authorities be mixed with in advance, be then placed in 25 DEG C of incubators and cultivate, often process repetition 4 times.After 2 days, adopt right-angled intersection method slide calliper rule to measure each process colony diameter cm, obtain and correct inhibition percentage %.
data adjust difference and statistical analysis
Two diameters are surveyed in each bacterium colony right-angled intersection, represent bacterium colony size with its mean.Colony growth inhibiting rate is obtained: colony growth inhibiting rate %=(blank bacterium colony increases diameter-chemicals treatment bacterium colony and increases diameter) * 100/ blank bacterium colony increases diameter by following formula.
the calculating of co-toxicity coefficient
On the bent basis of medicament bacteriostasis rate, carry out data analysis statistical by " DPS data handling system " 311 professional versions, obtain regression line, EC
50, correlation coefficient.According to the EC of Sun Yunpei (Y-P Sun) method by each process of mensuration
50be converted into actual poison exponent (ATI); According to the proportioning of mixture, calculate theoretical toxicity index (TTI), by the co-toxicity coefficient (CTC) of following formulae discovery mixture.
If co-toxicity coefficient is greater than 120, show there is synergistic effect; Between 80-120, be indicated as summation action; If be starkly lower than 100 (namely less than 80), be indicated as antagonism.
interpretation of result
Adopt five-spot to get five representational proportionings, and toxicity test is carried out to these 5 proportionings and standard agent.Result shows (see table 1), the EC of Thiodiazole-copper A, Tebuconazole B and 5 proportionings of the two (A:B is 8:1,4:1,1:1,1:4,1:8)
50be respectively 737.78,0.12,1.11,0.57,0.22,0.17,0.16mg/L.
Carry out analysis according to Sun Yunpei (sun etc. 1960) co-toxicity coefficient calculating means to test result to show (table 2), Thiodiazole-copper and the composite co-toxicity coefficient of Tebuconazole are between 84.37 ~ 109.07.All proportionings set by test all show
be addedeffect.
