Auxiliary material can be with alone or be used in combination.
Described bactericidal composition, its formulation are missible oil, wettable powder, suspending agent, aqueous emulsion or water dispersion granule.
Application of the above-mentioned bactericidal composition on preventing and treating fungal diseases of plants medicine is prepared.Especially in preventing and treating cereal
Application has remarkable result in terms of class, fruit tree, vegetable crop disease.
Above-mentioned application, described fungal diseases of plants are at least one of gray mold, white rot.
The characteristics of bactericidal composition of the present invention：
1st, the amine benzene pyrrole bacterium ketone and penconazole used in the present invention, the mechanism of action are different, mutual mixture will not produce it is low touch, can
Synergistic, dosage is reduced, reduces cost.
2nd, the present composition scope of application increase, suitable for preventing and treating Cereal, fruit tree, vegetables refractory fungal disease,
Particularly preventing and treating gray mold, white rot etc. has significant effect.Bactericidal composition of the present invention is to sac fungus, basidiomycetes, partly know
Bacterium and Oomycete fungal disease have good prevention effect；And suppress insect or fungi to unitary agent (amine benzene pyrrole bacterium ketone and
Penconazole is any) drug-fast generation.Bactericidal composition of the present invention can produce higher synergistic function, and the mixing
The dosage of the amount ratio independent reactive compound of thing substantially reduces, i.e., the activity of mixture is more than the activity of independent component.
Beneficial effects of the present invention compared with prior art：(1) compared with single dose, said composition antagonism fungal disease is such as
The fungal diseases such as gray mold, white rot have obvious synergistic function, overcome and have delayed the resistance to the action of a drug, expand preventing and treating spectrum, hence it is evident that
Improve prevention effect；(2) preventing and treating recruitment, drug cost are reduced；(3) alternative routine and the agricultural chemicals for being also easy to produce resistance；(4) with
Single dose is compared, and production and use cost reduce；(5) the drug-fast generation of fungi is suppressed, its positive effect uses higher than its single dose.
Embodiment
The invention will be further described with reference to embodiments, and the preparation method of formulation is conventional side in embodiment
Method, " % " of the present invention is mass percent.
Indoor biometricses are tested：
Mycelial growth rate method, EC of the measure different agents to bacterial strain are used indoors50Value, using co-toxicity coefficient calculating side
Method, the co-toxicity coefficient (CTC) of mixture is calculated, determines the building performance of mixture, circular is as follows：
EC (is generally selected as standard agent using a certain single dose in mixture50Junior), calculated：
Single dose toxicity index=standard agent EC50/ certain single dose EC50×100
The toxicity index of the toxicity index of theoretical toxicity index=A single doses × A single doses proportion+B single doses in mixture
× B single doses proportion in mixture
Survey the EC of toxicity index=standard single dose50The EC of value/mixture50Value × 100
Co-toxicity coefficient=actual measurement toxicity index/theoretical toxicity index × 100
Co-toxicity coefficient is classified：Mixture has synergetic when CTC is more than 120, is antagonism when CTC is less than 80, CTC exists
It is summation action between 80-120.
According to active ingredient amine benzene pyrrole bacterium ketone (A)：Penconazole (B) quality proportioning is：80:1、70：1、50：1、30：1、20：
1、10：1、5：1、2.5：1、1：1、1：2、1：4、1：6、1：10、1：20、1：30、1：50、1:60、1:70 are tested, and determine it
To Botrytis cinerea (Thanatephorus cucumeris (Frank) Donk.) co-toxicity coefficient.
Table 1：Indoor biometricses result of the amine benzene pyrrole bacterium ketone+penconazole different ratio to grape grey mould
Field control effectiveness test：
The pesticidal preparations preventing and treating grape grey mould experiment made from above-described embodiment.
1st, test process：This test medicine dosage sets three concentration for the treatment of, comparison medicine respectively according to the difference of each composition
Agent is the amine benzene pyrrole bacterium ketone SC of agricultural chemicals single dose 30% and 25% penconazole EW and blank clean water experiment respectively.
2nd, each plot area of test method is 66.7m2, it is repeated 3 times；Investigation drug effect side after investigating and prevent and treat before dispenser
