Description
Technical field
The invention belongs to technical field of pesticide, it is related to a kind of bactericidal composition of Fluxapyroxad-containsterilization in crop disease
Using.
Technical background
Fluxapyroxad (Fluxapyroxad) chemical name：3- (difluoro) -1- methyl-N- (3', 4', 5'- trifluoro [1,
1'- biphenyl] -2- bases) -1-H- pyrazoles -4- acid amides, fluxapyroxad belongs to pyrazole amide series bactericidal agent, and succinate dehydrogenase suppresses
Agent, superior lasting effect is integrated in one with lasting transmission characteristic.
Triazolone (triadimefon) chemical name：1- (4- chlorophenoxies) -3,3- dimethyl -1- (1H-1,2,4- tri-
Azoles -1- bases)-α-butanone, molecular formula：C14H16ClN3O2.Triazolone is a kind of efficient, low toxicity, low-residual, lasting period length, interior suction
The strong triazole bactericidal agent of property.After being absorbed by each several part of plant, it can be conducted in plant.Have to rust and powdery mildew pre-
The effect such as prevent, root out, treating, fumigating.To disease such as Helminthosporium carbonum, wheat class moire disease, wheat leaf blight, the phoenix of various crop
Pears black rot, maize head smut etc. are effective.It is safer to fish and birds.It is harmless to honeybee and natural enemy.Triazolone is killed
Bacterium mechanism principle is extremely complex, mainly suppresses the biosynthesis of thalline ergosterol, thus suppresses or interference thalline attachment spore
And the development of haustorium, the growth of mycelia and the formation of spore.The activity in live body is very strong to some germs for triazolone, but in vitro effect
It is really very poor.It is strong to the activity comparison spore of mycelia.Triazolone can be with the existing mixed existing use such as many fungicide insecticides, herbicide.
Bromothalonil (bromothalonil) chemical name：The bromo- 2 bromomethyl glutaronitriles of 2-, molecular formula：C6H6Br2N2, bromine bacterium
Nitrile is a kind of wide spectrum, low toxicity, mould proof, algae-killing bactericidal agent, can suppress and root out bacterium, the growth of fungi and algae, it is adaptable to spun
Corps diseases are had preferable prevention effect, especially had to anthracnose by the anti-corrosions such as fabric, leather, mould proof, industrial water algae removal
Special efficacy.
Antibiotic in pyrimidine nucleoside class（agricultural antiobiotic 120）Alias：Pesticide corrosion 120, antimycoin
120th, 120 agricultural antibiotic.Antibiotic in pyrimidine nucleoside class is a kind of broad-spectrum antibiotic, and it has strong to many phytopathogens
Inhibitory action, it is preferable to cucurbits powdery mildew, flowers powdery mildew and wheat rust preventive effect.
2-cyano-3-amino-3-phenylancryic acetate, chemical name：2- cyano group -3- amino -3- aminoacrylic acid ethyl esters, molecular formula：C12H12N2O2, cyanogen alkene
Bacterium ester is effective to disease caused by reaping hook mushroom, with protective effect and therapeutic action.Absorbed, had on blade by root
It is translocatable upwards, towards blade bottom and interlobate translocatable poor.
In the real process of agricultural production, controlling disease is easiest to generate the problem that the generation of disease drug resistance.No
Compounded with kind composition, be to prevent and treat resistance disease very common method.Heterogeneity is compounded, and is imitated according to practical application
Really, come judge certain compounding be synergy, plus and or antagonism.In most cases, the compounding effect of agricultural chemicals is all to add
And effect, really have the compounding of synergistic effect seldom, especially synergistic effect clearly, synergy ratio very high compounding just more
It is few.Study, found fluxapyroxad and triazolone, bromothalonil, antibiotic in pyrimidine nucleoside class, 2-cyano-3-amino-3-phenylancryic acetate by inventor
Mutually compounding, there is good synergistic effect within the specific limits, and about fluxapyroxad and triazolone, bromothalonil, pyrimidine core
