Abstract
The present invention relates to a kind of bactericidal composition containing mould spirit and fluopyram and application thereof.Described compositions contains mould spirit and fluopyram, and the weight ratio of described mould spirit and fluopyram is 1 40:1 35.Said composition can be applicable to prevent and treat industrial crops, Cereal or flowers and other crops disease control.Said composition is applied widely, effective, low cost, residual are low, safe for human, animal and environment.
Description
Technical field
The present invention relates to a kind of bactericidal composition and purposes, particularly relate to a kind of killing containing mould spirit and fluopyram
Bacteria composition and application thereof, is mainly used in the preventing and treating of industrial crops disease.
Background technology
Mould spirit (Hymexazol, CAS 10004-44-1) is the systemic fungicide of a kind of wide spectrum.Can directly be planted
Thing root absorption, enters in plant, mobile extremely rapid.Move in root system and within only 3 hours, just move to stem, 24 little time shifts
Move to plant whole body.This product mechanism of action is unique, efficiently, low toxicity, nuisanceless, can suppress the mycelial normal life of pathogenic fungi
Grow or directly kill pathogenic bacteria, plant growing can be promoted again.
Fluopyram (Fluopyram, CAS 658066-35-4) is pyridinylethylbenzamderivatives class disinfecting
Agent, a kind of broad spectrum type antibacterial.Mechanism of action is that the succinate dehydrogenase in the Complex II of mitochondrial respiratory chain is risen suppression
Effect, thus suppress the kind spore germination of target fungus, germ tube and mycelial growth.Tool Uptake and translocation so that it is old in protection
Plant tissue simultaneously, the blade newly grown out, flower and fruit are also had good protective effect.Transmit through xylem,
Speed is fast, the position of two days young sprouts of arriving；It can also transmit through phloem, is applied on blade and just can be passed to rapidly other
Position.In addition, moreover it is possible to active at plant surface, permeability is the strongest, it is possible to penetrates into and goes in the cell of plant, tool
Thin layer is had to penetrate activity.
Mould spirit is applied relatively broad at present, but due to life-time service, many places all occur in that resistance problem, cause using
Amount continues to increase, and residual risk increases, and is unfavorable for food safety.Seek scientific and rational agriculture chemical compounding, be to solve this problem
Preferably way.Fluopyram fungicidal spectrum is wide, excellent to control of crop disease, but with high costs, applies the most at home very
Few.
There are no at present mould spirit and the compounding relevant report of fluopyram both at home and abroad.If both can compound one
Rise, it becomes possible to preferably solve above-mentioned produced problem, compare single dose after the two is compounding simultaneously and there is synergistic function, improve
The effect that single dose is used alone.The most also there is no the relevant report that mould spirit and fluopyram compound at present.
Summary of the invention
An object of the present invention is to overcome above-mentioned deficiency, it is provided that one is applied widely, effective, consumption is low, one-tenth
This is the lowest, lasting period length, remain little and have potentiation containing mould spirit and the bactericidal composition of fluopyram.
The two of the purpose of the present invention are to provide a kind of bactericidal composition containing mould spirit and fluopyram for preventing
Control the purposes of industrial crops disease.
The object of the present invention is achieved like this:
A kind of containing mould spirit with the bactericidal composition of fluopyram, the activity contained by described compositions becomes to include
Mould spirit and fluopyram, the weight ratio of described mould spirit and fluopyram is 1-40:1-35.
The preferred weight ratio of described mould spirit and fluopyram is 3-5:20-30.
It is highly preferred that the weight ratio of the two is 1-12:1-10；
Most preferably, the weight ratio of the two is 1:1.
Described combination dosage form is any one dosage form allowed on pesticide.Such as wettable powder, water dispersible granules, outstanding
Floating agent, aqueous emulsion, cream or seed coat agent etc..
Described mould spirit and fluopyram percentage by weight in above-mentioned dosage form are 5～75%.
Further, the present invention provides a kind of bactericidal composition containing mould spirit and fluopyram as above
Purposes, by described Bactericidal composite for being used for control economic disease of pests evil；Preferably, described disease is: powdery mildew of strawberry, grey mold
Disease, anthrax, droop, peach tree shot hole, anthrax, brown rot, tomato late blight, early blight, gray mold, Citrullus vulgaris is climing withered
Disease, droop, anthrax, cucumber downy mildew, powdery mildew, gray mold, Camellia sinensis anthrax, gall of tea, bud blight, Fructus Vitis viniferae downy mildew
Disease, gray mold, white rot, anthrachose of grape, tobacco downy mildew, balck shank, damping off, pear scab, rust, ring spot, rot
Sick, melasma, scab of apple, brown spot, citrus anthracnose, foot rot, blossom-end rot, capsicum epidemic disease, leaf spot of peanut, vertical withered
Disease, sclerotinia rot of colza, the late blight of potato, cotton seedling blight, red rot, coffee rust, brown spot, mango anthracnose, white lead
Sick, blossom-end rot, sigatoka, scab, bunchy top, sheath maize ear rot, sclerotinia rot of colza, downy mildew etc..It is preferred for Sclerotina Sclerotiorum in Winter Rape
Core disease, pear scab, Fructus Mangifera Indicae blossom-end rot, apple marssonina leaf spot and the preventing and treating of Fructus Fragariae Ananssae droop.
Compared with prior art, the invention has the beneficial effects as follows:
(1) potentiation that the present composition is done well in certain ratio range, the bactericidal effect ratio of compositions
Single dose is obviously improved, and its co-toxicity coefficient is at least more than 120, reduces Pesticide use dosage and cost simultaneously, decreases
Residual, also mitigates the harmful effect to environment；
(2) in the present invention, the mechanism of action of two kinds of active component is different, and the application of compositions can delay or overcome cause of disease
The resistance of bacterium, extends the service life of product；
(3) present composition is excellent to industrial crops disease preventive effect, additionally, can also be used for the anti-of its corps diseases
Control.
