Abstract
The invention discloses a sterilizing composition containing penflufen and metalaxyl-M and application of the sterilizing composition. The sterilizing composition disclosed by the invention is efficient, safe and environment-friendly, has a synergistic effect, is capable of increasing the yield of crops, improving the quality of fruits and reducing the cost, and is beneficial for delaying the generation of drug resistance. The sterilizing composition can be used for preventing various crop diseases such as banded sclerotial blight, a bakanae disease, downy mildew and powdery mildew.
Description
Technical field
The present invention relates to new bactericidal composition, it includes active ingredient fluorine azoles bacterium aniline and Metalaxyl-M, described combination
Thing is very suitable for preventing various plants pathomycete on crops.
Background technology
Fluorine azoles bacterium aniline, English common name: penflufen, it is a kind of succinate dehydrogenase inhibitors, mainly acts on
Respiratory chain electron transmission complex II, blocks energetic supersession；Kind of a biography, the basidiomycetes of soil biography and sac fungus disease can be prevented and treated, main
Black scurf of potato that rhizoctonia to be had causes, wheat sharp eyespot, rice sheath blight disease, sclerotinia rot of colza etc., also wheat dissipates black
Fringe disease, the bunt of wheat, corn southern leaf blight etc..Seed after process can absorb fluorine azoles bacterium aniline in germination process, logical
Cross xylem and be transmitted to other positions of plant, play the effect of cover crop.
Metalaxyl-M, English common name: Metalaxyl-M, is the efficient systemic fungicide of Syngenta Co., Ltd's exploitation,
There is protection and therapeutic action, can be absorbed rapidly by plant roots cauline leaf, and in plant, run to each position, thus resistance to rain
Water washes away, efficient to diseases such as the vegetables caused by downy mildew, phytophthora root rot, rotten mildew fungus, fruit tree, cereal crops.
Applicant, through retrieval, there is presently no fluorine azoles bacterium aniline and the report of Metalaxyl-M composition research.Inventor passes through
Bactericidal composition is compounded the research of effect, is found surprisingly that bactericide compounded uses different for the above two mechanism of action,
The effect of Synergistic can be reached.
Summary of the invention
It is an object of the invention to provide a kind of have that synergistic function, use cost be low, preventive effect is good containing fluorine azoles
Bacterium aniline and the synergetic pesticide composition of Metalaxyl-M.
For achieving the above object, the present invention proposes following technical scheme: a kind of bactericidal composition, its active ingredient includes fluorine
Azoles bacterium aniline and Metalaxyl-M, both percentage by weights are 1:30-30:1, preferably 1:10-10:1, more preferably 7:2.
Further, active ingredient accounts for the weight percentage of composition is 1-90%, preferably 10-50%.
Further, the conventional method during described composition is processed according to the formulations of pesticide is processed into water dispersible granules, wettable
Property pulvis, microemulsion, aqueous emulsion, suspending agent or seed treatment.
Further, described composition can be used for preventing and kill off various crop disease, preferably banded sclerotial blight, downy mildew.
Compared with prior art, the invention have the benefit that
1, the bactericidal composition of the present invention, shows obvious synergy to rice sheath blight disease, cucumber downy mildew within the specific limits
Effect, the prevention effect of composition is compared than single dose and is significantly improved, and reduces Pesticide use dosage and use cost, decreases
Pollution to environment.
2, the bactericidal composition of the present invention, the active component mechanism of action is different, and pathogen can be delayed drug-fast
Produce, be conducive to extending the service life of active component.
3, the bactericidal composition of the present invention has crop safety, the effect of volume increase.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further details.
One, Toxicity Determination
Test objective thing is rice sheath blight disease, cucumber downy mildew, and test uses colony diameter method.Take fluorine azoles bacterium aniline and essence first
Frost spirit mother liquor, is configured to liquid flat board, every ware about 10 mL, and each drug concentration arranges 3 repetitions, separately arranges blank
(adding sterilized water).By cultured rice sheath blight disease, cucumber downy mildew, produce mycelia with the sterilizing card punch of a diameter of 0.5 cm
Block, moves respectively on different culture medium flat plates, cultivates 3 days, measures colony diameter (mm), and calculate bacteriostasis rate, pass through for 28 DEG C
Linear regression analysis between probit value and the logarithm value of series concentration of inhibiting rate, obtains the EC50 of each process, uses Sun Yunpei
Method calculate mixture spend coefficient (CTC) together, evaluate the medicament activity to germ with this.Result of the test is shown in Table 1, table 2.
Table 1 it can be seen that fluorine azoles bacterium aniline and Metalaxyl-M are when 1:30-30:1, the Toxicity Determination to rice sheath blight disease,
Co-toxicity coefficient is all higher than 120, shows synergistic function, and wherein, during 1:10-10:1, co-toxicity coefficient is all higher than 130, collaborative
Synergistic effect is more preferably.
Table 2 is it can be seen that fluorine azoles bacterium aniline and Metalaxyl-M are when 1:30-30:1, and the preventing and treating to cucumber downy mildew all shows as
Synergistic function.And when 1:10-10:1, CTC value is all higher than 130, synergistic function is more preferably.
