Description
Technical field
The present invention relates to a kind of agricultural bactericidal composition, effective ingredient includes pyrrole bacterium benzene prestige, pyridine acyl
Bacterium amine.
Background technology
Pyrrole bacterium benzene prestige, belongs to the novel antibacterial of Benzylcarbamate structure, main by broken
MC electron transport system in bad pathogen cell, hinders pathogen spore germination and prevents
After spore germination, host is infected and play a role, to gray mold, sclerotiniose specially good effect.
Boscalid is Novel tobacco acid amide fungicides, in 2004 Britain, Germany and
Switzerland registers.Boscalid belongs to succinic acid ubiquinone reductase suppression in mitochondrial respiratory chain
Agent, has a strongest rejection ability to the sprouting of spore, and with other antibacterial no interactions resistance.
Boscalid is mainly shifted in plant by blade face infiltration, suppresses mitochondrial succinate acid esters dehydrogenation
Enzyme, hinders tricarboxylic acid cycle, makes aminoacid, sugar shortage, energy reduce, dividing of interference cell
Split and grow, disease is had neural activity, there is protection and therapeutical effect.Suppression spore germination,
The extension of antibacterial pipe, mycelial growth and spore mother cell form fungus growth and the main rank of breeding
Section, bactericidal action is directly caused by parent active agent, does not has corresponding metabolic activity.With many bacterium
The no interactions resistances such as spirit, Sukeling, are mainly used in preventing and treating powdery mildew, gray mold, various rot
Disease, brown rot and root rot etc..
Grey mould fruit rot of strawberry is disease common during strawberry cultivating, and China's cultivated strawberry area is all
Having generation, 20 century 70 sequela gradually increase the weight of, especially south the fruit picking phase on the occasion of
In the spring rain time, fall ill even more serious.Grey mould fruit rot of strawberry often results in real rotten susceptible variety
Diseased fruit rate is about 30%, serious up to more than 60%, to Fructus Fragariae Ananssae yield, qualitative effects very
Greatly.Main infringement blade and petiole, morbidity is many from the florescence, and pathogenic bacteria initially loses from by opening
Flower or weaker position are infected, and make flower rot in light brown necrosis, produce the mould layer of Lycoperdon polymorphum Vitt.Leaf
How to invade from base portion strong yellow limb edge, form " V " font brown spot, or drop along petal
Position infect, formed subcircular ecthyma gangrenosa, it has and the most significantly takes turns stricture of vagina, upper life is diluter
Dredge grey mold.Fruit is caught an illness many from the beginning of the petal remained or the position coming close to or in contact with ground, also
Can invade from the position of early stage with invalid contact tissue, just downright bad, subsequently in water stain shape taupe
Darkening, fruit rot, surface produces the dense mould layer of Lycoperdon polymorphum Vitt.Petiole is fallen ill, in shallow brown
Color is downright bad, drying shrinkage, and it produces sparse grey mold.
In actual survey is studied, it has been found that pyrrole bacterium benzene prestige, Boscalid are compounded,
Have obviously preventive and therapeutic effect to grey mould fruit rot of strawberry, according to long-term tracking test, this compounds
Dosage form, is difficult to produce resistance in actual application, and in use, consumption is non-
The lowest, the negative effect to environment is the least.
Pyrrole bacterium benzene prestige and Boscalid mixture are used for preventing and treating grey mould fruit rot of strawberry, there is no relevant report at present
Road.
Summary of the invention
It is an object of the invention to provide a kind of efficient, safe and environment-friendly, low toxicity and the lasting period be long,
Having the bactericidal composition of potentiation, it can effectively prevent and treat grey mould fruit rot of strawberry.
For achieving the above object, the technical solution adopted in the present invention is: a kind of containing pyrrole bacterium benzene
Prestige and the bactericidal composition of Boscalid, auxiliary including pyrrole bacterium benzene prestige and Boscalid and pesticidal preparations
Co-ingredients, the ratio of weight and number of pyrrole bacterium benzene prestige and Boscalid is 1:10～10:1, pyrrole bacterium
Benzene prestige and Boscalid weight summation percentage by weight in bactericidal composition are 5%～70%.
Further, in bactericidal composition, pyrrole bacterium benzene prestige and Boscalid preferred weight portion rate are
3:1。
The bactericidal composition of the present invention can have been selected according to well known to a person skilled in the art method
The pesticidal preparations auxiliary element known, is configured to Multiple Pesticides dosage form.In the present invention, the present invention
Bactericidal composition is preferably formulated to two kinds of environmental protection dosage forms such as suspending agent and water dispersible granules.
The bactericidal composition of the present invention is used for preventing and treating grey mould fruit rot of strawberry, Ying.
The bactericidal composition of the present invention, generally uses the method for spraying to use, it is also possible to according to need
Use other use technology agriculturally applied.
The bactericidal composition of the present invention has the advantages that:
1, the bactericidal composition of the present invention, shows obvious potentiation in certain ratio range
Effect, the prevention effect of compositions is significantly improved than single dose, reduces the use agent of pesticide
Amount, decreases times for spraying, reduces drug cost, decrease pesticide to ecological environment not
Profit impact.
2, the bactericidal composition of the present invention, two kinds of effective ingredient mechanism of action are different, can
To overcome long-term single use easily to produce the shortcoming of resistance, extend the service life of medicament, right
The comprehensive control important in inhibiting of Disease Resistance.
3, the bactericidal composition of the present invention, drug effect plays rapidly, and the lasting period is long, use cost
Low, easy to use, time saving and energy saving, its popularization and application have huge economic benefit and society's effect
Benefit.
4, the bactericidal composition dosage form environmental protection of the present invention, to crop safety.
Detailed description of the invention
