Abstract
The invention belongs to the field of agricultural bactericide, in particular to an agricultural compound bactericide. Fluoride thiazole ethanone and tiaprofenic fluopicolide, with the weight ratio of 1 to 0.1-10, preferably 1 to 2-3, are used as the effective ingredients of the agricultural compound bactericide. The agricultural compound bactericide enlarges the bactericidal spectrum, has extremely high activity against pathogenic bacteria such as cucumber downy mildew, grape downy mildew, blight, Phytophthora infestans, potato late blight and powdery mildew of vegetables and the like. The synergistic effect is obvious, and is not the simple superposition of the activities of all components but the obvious synergistic effect. The treatment and prevention effect is strong, effective period is long, and resistance risk is small. The amounts of the effective ingredients used in field are reduced, thus production cost and use cost are reduced, and environmental pollution and pesticide residues are further reduced. The agricultural compound bactericide is composed of the effective ingredients with different action mechanisms, and is conducive to overcoming and delaying the emergence of the drug resistance of bacteria, and is safe to crops.

Detailed description of the invention
First indoor measurement fluorine thiazole pyrrole ethyl ketone and the benzene metsulfovax different ratio prevention effect to cucumber downy mildew.Test
Method is as follows: after being activated in PDA culture medium by bacterium of downy mildew of cucumber, takes bacterium dish from its edge card punch and is placed in PDA training
Supporting on base, after its growth 48h, take bacterium dish with the card punch of a diameter of 5mm from its colony edge, what access had been inverted in advance contains
In the PDA culture medium that different ratio drug concentration processes, be placed in hot-house culture case cultivating, after inoculation 1,3,5d subtracts respectively
Hold mycelial growth situation, and measure colony diameter.Comparison CK1 (fluorine thiazole pyrrole ethyl ketone) and CK2 (benzene metsulfovax) are set, by fluorine thiophene
Azoles pyrrole ethyl ketone does 5 concentration for the treatment of respectively with each proportioning of benzene metsulfovax different ratio, and each concentration for the treatment of does 4 repetitions.
Prevention effect is converted into probability value (y), and liquor strength (μ g/mL) is converted into logarithm value (x), and the suppression setting up different ratio is several
Rate value and its log concentration regression equation (toxicity regression formula), calculate concentration EC50 in the suppression of each proportioning with method of least square
Value, and obtain the coefficient of synergism SR of different ratio, evaluate the potentiation of built agent according to coefficient of synergism, determine optimum proportioning.
Disease index, prevention effect, coefficient of synergism computing formula are as follows:
In above formula, A represents fluorine thiazole pyrrole ethyl ketone, and B represents benzene metsulfovax, and a, b represent fluorine thiazole pyrrole ethyl ketone and benzene thiophene bacterium respectively
Amine ratio in mixture.
Make evaluation according to coefficient of synergism SR: when SR is more than 1.5, show that mixture has potentiation, when SR 0.5～
For being added when 1.5, it is antagonism when SR is less than 0.5.
Fluorine thiazole pyrrole ethyl ketone and benzene metsulfovax different ratio are as shown in table 1 to the toxicity test result of cucumber downy mildew, increase
Effect measurement result is as shown in table 2.Wherein, CK1 is fluorine thiazole pyrrole ethyl ketone single dose, and CK2 is benzene metsulfovax single dose.

Underneath with embodiment 1,4,6 medicament and comparative example 1～2 medicament as shown in table 3 extension rate to cucumber downy mildew
Carrying out land for growing field crops spray testing, so that beneficial effects of the present invention is better described, result of the test is as shown in table 3 below.Wherein: embodiment
1:50% fluorine thiazole pyrrole ethyl ketone benzene metsulfovax wettable powder, embodiment 4:60% fluorine thiazole pyrrole ethyl ketone benzene metsulfovax moisture
Shot agent, embodiment 6:40% fluorine thiazole pyrrole ethyl ketone benzene metsulfovax aqueous suspension agent, the benzene metsulfovax aqueous suspension of comparative example 1:30%
Agent, comparative example 2:20% fluorine thiazole pyrrole ethyl ketone water dispersible granules.
This test sets embodiment 1,4,6 medicament, comparative example 1～2 medicament and does not use totally 6 process of any medicament, often
Individual process is repeated 4 times, and totally 24 process community, implements spray medicine in cucumber downy mildew their early stage.Often process community and take 3 at random
Point, every takes 6 strain Fructus Cucumidiss sativi, respectively 10 days, 20 days, the blade investigated on Fructus Cucumidis sativi for 30 days and stem scab number, scab after medication
Area, calculates prevention effect with disease index.
Scab grade scale is with reference to National Standard of the People's Republic of China " pesticide field efficacy medicine test criterion ".Blade is fallen ill
Degree is divided into 6 grades, 0 grade: blade is without scab；1 grade: lesion area accounts for whole blade area less than 5%；2 grades: lesion area accounts for whole
Individual blade area 6%～10%；3 grades: lesion area accounts for whole blade area 11%～25%；4 grades: lesion area accounts for whole leaf
Sheet area 26%～50%；5 grades: lesion area accounts for whole blade area more than 50%.When carrying out Disease investigation, if any serious dye
