The present invention relates to a kind of bactericidal composition containing cyprodinil and iprovalicarb and application thereof.The composition contains cyprodinil and iprovalicarb, and the weight ratio of the cyprodinil and iprovalicarb is 1 40:1‑45.Said composition can be applied to prevent and treat industrial crops, Cereal or flowers and other crops disease control.Said composition is applied widely, effect is good, cost is low, residual is low, safe for human, animal and environment.
Description
Technical field
The present invention relates to a kind of bactericidal composition and application thereof, more particularly to a kind of killing containing cyprodinil and iprovalicarb
Bacteria composition and application thereof, it is mainly used in the preventing and treating of industrial crops disease.
Background technology
Cyprodinil (Cyprodinil, CAS 121552-61-2) is a kind of methionine biosynthesis inhibitor, with three
The no interactions resistances such as azole, imidazoles, morpholine class, phenylpyrrole class, have protection, treatment, blade penetrate and root in inhale work
Property.Foliar spray or seed treatment, it can also do barley seed coat agent medication.
Iprovalicarb (Carbamic acid, CAS 140923-17-7) is amino-acid ester analog derivative, has the complete of uniqueness
New biomimetic features make its mechanism of action be different from other bactericide for preventing and treating Oomycetes.Its mechanism of action is to act on fungal cell
The synthesis of wall and protein, infecting and sprouting for spore can be suppressed, while mycelial growth can be suppressed, caused it to deform, be dead
Die.There is treatment and eradicant action well for Peronosporaceae and the fungus-caused disease of Phytophthora.
Although cyprodinil has above-mentioned advantage, but be used alone and easily produce resistance；Although iprovalicarb drug effect is high, sterilization
Spectrum is narrower.From the perspective of pesticides application, long-term single use a certain kind agricultural chemicals, preventive effect reduction is all easily caused, dosage increases
Greatly, develop immunity to drugs, the lasting period shorten the problems such as, remain increased risk, be unfavorable for environment harmonious development.Seek science, rationally
Agriculture chemical compounding, be solve the preferable method of this problem.At present at home and abroad there are no cyprodinil and iprovalicarb compounding
Relevant report.If both can compound together, it becomes possible to preferably solve above-mentioned produced problem, while phase after the two compounding
There is synergistic function than single dose, improve the effect that single dose is used alone.There is no cyprodinil and figured silk fabrics also at home and abroad at present
The relevant report of mould prestige compounding.
The content of the invention
An object of the present invention is to overcome above-mentioned deficiency, there is provided one kind is applied widely, effect is good, cost is low, holds
The effect phase is long and has the bactericidal composition containing cyprodinil and iprovalicarb of synergistic effect.
The second object of the present invention is that providing a kind of bactericidal composition containing cyprodinil and iprovalicarb is used to prevent and treat
The purposes of plurality of plant diseases.
The object of the present invention is achieved like this：
A kind of bactericidal composition containing cyprodinil and iprovalicarb, the activity contained by the composition is into including phonetic bacterium
Cyclammonium and iprovalicarb, the weight ratio of the cyprodinil and iprovalicarb is 1-40:1-45.
The preferred weight ratio of the cyprodinil and iprovalicarb is 3-35:5-45；
It is highly preferred that the weight ratio of the two is 1-9:1-15；
Most preferably, the weight ratio of the two is 1：1.
The combination dosage form is any one formulation allowed on agricultural chemicals.It is such as wettable powder, water dispersible granules, outstanding
Floating agent, aqueous emulsion, missible oil or seed coat agent etc..
The percentage by weight of the cyprodinil and iprovalicarb in above-mentioned formulation is 5~85%.
Further, the present invention provides a kind of use of bactericidal composition as described above containing cyprodinil and iprovalicarb
On the way, it is to be done harm to for control economic disease of pests by the Bactericidal composite；Preferably, it is grey mould fruit rot of strawberry, powdery mildew, anthracnose, withered
Wither disease, tomato late blight, watermelon grafting, droop, anthracnose, gall of tea, bud blight, downy mildew of garpe, powdery mildew, grey mold
Disease, vegetable downy mildew, clubroot, droop, tobacco bacterial wilt, balck shank, samping off, anthracnose, pear scab, apple wheel
Line disease, spot defoliation, citrus anthracnose, foot rot, capsicum epidemic disease, leaf spot of peanut, damping-off, sclerotinia sclerotiorum, downy mildew
Disease, the late blight of potato, rice seedling blight, rice blast, red rot, Chinese rose downy mildew, gray mold, powdery mildew, balsamine downy mildew
Disease, gray mold or rotten mildew etc..
It is preferred for strawberry droop, watermelon grafting, Tobacco seedling diseases, downy mildew of garpe, rice seedling blight or Chinese rose
The preventing and treating of gray mold.
Unless otherwise indicated, " % " in the application is weight percentage.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) synergistic effect that the present composition is done well in certain ratio range, the bactericidal effect ratio of composition
Single dose is obviously improved, and its co-toxicity coefficient is at least more than 120, while reduces Pesticide use dosage and cost, is reduced
Residual, also mitigates the harmful effect to environment；
(2) mechanism of action of two kinds of active components is different in the present invention, and the application of composition can delay or overcome cause of disease
The resistance of bacterium, extend the service life of product；
(3) present composition is excellent to industrial crops disease preventive effect, in addition, it can also be used to which its corps diseases is prevented
Control.
