Description
Technical field
The invention belongs to disinfectant use in agriculture field, the compounding of more particularly to a kind of fluorine bacterium azoles of alkene containing benzo and tetraconazole is killed
Microbial inoculum.
Background technology
Used with the popularization of agricultural chemicals with a large amount of, the bactericide kind of single-activity component is deposited in disinfectant use in agriculture preventing and treating
Bactericidal range it is narrow, prevention effect is poor, dispenser dosage is big, be also easy to produce the resistance to the action of a drug and poisoning, application times are more, it is dirty to aggravate environment
Many drawbacks such as dye have clearly resulted in a large amount of underproduction of crops and being significantly increased for production cost.Agriculturally produced for preventing and treating
The germ of raw resistance, a kind of method are to release the new new component with existing kind no interactions resistance.But new active ingredient
Development cost it is high, construction cycle length, and all do not catch up with the speed that germ produces resistance forever.Other methods such as crop
Distributing adjustment, different agricultural chemicals rotations etc., during practical operation, it is difficult to really play obvious effect.
Benzo alkene fluorine bacterium azoles are a kind of pyrazole amide series bactericidal agents, are acted on pathogen mitochondrial respiratory electron transport chain
Protein complexes II, i.e. succinate dehydrogenase (succinate dehydrogenase, SDH) or butanedioic acid-ubiquinone reductase
(succinate ubiquinone reductase, SQR), influences the respiratory chain electron transport system of pathogen, hinders its energy
Amount metabolism, suppresses the growth of pathogen, causes it dead, so as to reach the purpose of controlling disease.The bactericide is mainly used in paddy
Class crop, there is outstanding preventive effect to the Major Diseases of the various crops such as wheat, corn and special crop, wheat leaf can be prevented and treated well
Rot, the cercospora black spot of peanut, take-all and wheat basal stem rot, especially have to wheat powdery mildew, corn southern leaf blight and gray mold
Special efficacy is excellent to Asian Soybean Rust preventive effect.Itself and methoxy acrylic and triazole bactericidal agent no interactions resistance, can be with
With various sterilization agent compounding use.
Tetraconazole is a kind of OTC class agricultural chemicals, is the respiration and cell propagation for suppressing fungal mitochondria, has
The biosynthesis inhibitor of uptake and translocation effect, mainly thalline ergosterol, have with benzimidazole medicaments such as bacterium spirits and just interact
The resistance to the action of a drug.Suitable for crop cereal crop such as wheat, barley, oat, rye etc., fruit tree such as banana, grape, pears, apple etc., vegetable
Dish is for example melon, beet, ornamental plant etc..Controlling object is Erysiphe, Puccinia, beak genuss, nuclear cavity Pseudomonas and septoria musiva
Belong to microbial disease such as wheat powdery mildew, loose smut of wheat, wheat rust, the bunt of wheat, wheat grain husk blessing disease, barley
Moire disease, loose smut of barley, barley banded sclerotial blight, maize head smut, head smut of sorghum, melon and fruit powdery mildew, banana tikka
Disease, alternaria leaf spot of apple, pear scab and uncinula necator etc..
The content of the invention

Embodiment
The present invention is further explained below in conjunction with embodiment：
Prevention effect of the indoor measurement by benzo alkene fluorine bacterium azoles with tetraconazole different ratio to uncinula necator first.Examination
Proved recipe method is as follows：After grape powdery mildew is activated in PDA culture medium, bacterium dish is taken to be placed in PDA from its edge with card punch
On culture medium, after it grows 48h, bacterium dish is taken from its colony edge with a diameter of 5mm card punch, what access had been inverted in advance
Drug concentration containing different ratio processing PDA culture medium on, be placed in cultivating in hot-house culture case, 1 after inoculation, 3,5d difference
Mycelial growth situation is reduced, and measures colony diameter.Control CK1 (benzo alkene fluorine bacterium azoles) and CK2 (tetraconazole) is set, by benzene
And alkene fluorine bacterium azoles and each proportioning of tetraconazole different ratio do 5 concentration for the treatment of respectively, each concentration for the treatment of does 4 weights
It is multiple.Prevention effect is converted into niqueMin (y), liquor strength (μ g/ml) is converted into logarithm value (x), establishes the suppression of different ratio
NiqueMin processed and its log concentration regression equation (toxicity regression formula), concentration in the suppression of each proportioning is calculated with least square method
EC50 values, and the coefficient of synergism SR of different ratio is obtained, the synergistic effect of built agent is evaluated according to coefficient of synergism, it is determined that most preferably matching somebody with somebody
Than.
Disease index, prevention effect, coefficient of synergism calculation formula are as follows：
A represents benzo alkene fluorine bacterium azoles in above formula, and B represents tetraconazole, and a, b represent benzo alkene fluorine bacterium azoles and tetrafluoro ether respectively
Ratio of the azoles in mixture.
Evaluation is made according to coefficient of synergism SR：When SR is more than 1.5, show that mixture has synergistic effect, when SR 0.5~
It is antagonism when SR is less than 0.5 to be added when 1.5.
Benzo alkene fluorine bacterium azoles and tetraconazole different ratio are as shown in table 1 to the toxicity test result of uncinula necator, increase
It is as shown in table 2 to imitate measurement result.Wherein, CK1 is benzo alkene fluorine bacterium azoles single dose, and CK2 is tetraconazole single dose.

Underneath with the medicament of embodiment 1,4,6 and the medicament of comparative example 1~2 as shown in table 3 extension rate to uncinula necator
Crop field spray testing is carried out, so that beneficial effects of the present invention are better described, result of the test is as shown in table 3 below.Wherein：Embodiment
1：50% benzo alkene fluorine bacterium azoles tetraconazole wettable powder, embodiment 4：60% benzo alkene fluorine bacterium azoles tetraconazole moisture
Shot agent, embodiment 6：40% benzo alkene fluorine bacterium azoles tetraconazole aqueous suspension agent, comparative example 1：30% tetraconazole aqueous suspension
Agent, comparative example 2：20% benzo alkene triflumizole water dispersant.
The medicament of embodiment 1,4,6, the medicament of comparative example 1~2 are set in this experiment and is handled for totally 6 without using any medicament, often
Individual processing is repeated 4 times, totally 24 processing cells, implements to spray in uncinula necator early stage.Often processing cell takes 3 at random
Point, every takes 6 plants of grapes, respectively 10 days after medication, 20 days, the 30 days blades and stem scab number, scab investigated on grape
Area, prevention effect is calculated 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 disease-free spot；1 grade：Lesion area accounts for whole blade area below 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
Piece area 26%~50%；5 grades：Lesion area accounts for whole blade area more than 50%.When carrying out Disease investigation, if any serious dye
The leaf abscission of disease, it is included in using leaf scar as according to the blade as highest morbidity series in statistics.Disease refers to and prevention effect
Calculate as follows：
Prevention effect of the different disposal of table 3 to uncinula necator
