Description
Technical field
The invention belongs to crop disease control field, it particularly relates to be a kind of to be used to prevent and treat oomycetes diseases
Composition pesticide, the pesticide combination includes component A and component B, and wherein component A is folpet, and component B is benzo alkene fluorine bacterium
Azoles.
Background technology
Oomycetes disease such as downy mildew, epidemic disease are diseases common in proportion of crop planting, yield and quality band to crops
Carry out very big damage.In the last few years, as the increase of China's cultivated area, causing harm for the vegetables production of oomycetes disease are also increasingly tight
Weight, the various diseases as caused by oomycetes are all the very strong species of harmfulness, although species is few, morbidity is rapid, propagates fast, danger
Evil weight.According to the literature, due to single drug and other irrational medications, already lead to some oomycetes disease such as downy mildew,
The diseases such as epidemic disease generate the resistance to the action of a drug to Multiple Pesticides, cause the prevention effect of these agricultural chemicals to decline, and for effectively preventing
Disease has in turn resulted in the pollution of environment, it is necessary to further increased to the usage amount of agricultural chemicals, is unfavorable for the sustainable development of agricultural
Exhibition.Therefore, find efficient, low toxicity, drug-fast novel agrochemical kind can be delayed to be one of important channel for solving the problem.
Folpet is organosulfureous fungicide, is mainly used in preventing and treating cereal crops, vegetables, the multiple diseases on fruit tree, and right
Plant growth has certain stimulation, and folpet can be widely used for preventing and treating rice blast, banded sclerotial blight, wheat rust, red mould
The multiple diseases such as disease, the late blight of potato, early blight of tomato, apple anthracnose.
The common name benzovindiflupyr of benzo alkene fluorine bacterium azoles, trade name Solatenol, CAS accession number are
1072957-71-1, benzo alkene fluorine bacterium azoles are first just up to the pyrazole amide series bactericidal agent of exploitation, are succinate dehydrogenase inhibitors.
The bactericide is mainly used in cereal crops, has outstanding preventive effect to the Major Diseases of the various crops such as wheat, corn and special crop,
Wheat leaf blight, the cercospora black spot of peanut, take-all and wheat basal stem rot can be prevented and treated well, especially to wheat powdery mildew, jade
Rice helminthosporium maydis and gray mold have special efficacy, excellent to Asian Soybean Rust preventive effect.It is killed with methoxy acrylic and triazole type
Microbial inoculum no interactions resistance, can be with various sterilization agent compounding use.Although benzo alkene fluorine bacterium azoles prevention effect is good, to use into
This higher and long-term use of generation for easily causing resistance, so as to reduce its service life.
How to delay the life-span of pesticide activity component is one of major issue to be solved, by different action of agricultural chemicals mechanism
It is a kind of relatively conventional mode that pesticide species, which carry out compounding,.Present inventor is exactly will not as point of penetration, research
Compounded, be found surprisingly that with pesticide species and benzo alkene fluorine bacterium azoles, after folpet and benzo alkene fluorine bacterium azoles are compounded,
Mutual effect is not simply to be superimposed, but can obtain unexpected cooperative synergism effect within the specific limits,
After further research, the present invention is completed, in addition, inventor by substantial amounts of retrieval, is also found no on by folpet
The relevant report compounded with benzo alkene fluorine bacterium azoles.
The content of the invention
It is an object of the invention to provide a kind of prevention effect is good, synergistic sterilizing composition to crop safety.
Another object of the present invention is to provide the synergistic sterilizing composition to be used to prevent and treat corps diseases, especially
It is the purposes of oomycetes diseases.
Another object of the present invention also resides in a kind of method for preventing and treating corps diseases that provides, including the collaboration by the present invention
The methods of Synergistic bactericidal composition is such as sprayed by conventional method, spread fertilizer over the fields, atomizing, drip irrigation and the environment of pathogen or its existence enter
OK.
To achieve these goals, technical scheme obtains in the following manner：
A kind of synergistic sterilizing composition, its active component comprise at least folpet and benzo alkene fluorine bacterium azoles.
In order to reach synergistic function, the weight ratio of folpet and benzo the alkene fluorine bacterium azoles is 30:1-1:10.
Further, the weight ratio of folpet and benzo the alkene fluorine bacterium azoles is preferably 20:1-1:1.
Further, active component accounts for the percentage by weight of composition in synergistic sterilizing composition of the present invention
For 15-80%, preferably 20-60%, remaining is the conventional auxiliary element in Pesticide formulation, such as dispersant, wetting agent, breast
The auxiliary agents such as agent, stabilizer, antifreezing agent, disintegrant, binding agent, solvent and other active ingredients that are beneficial to are stablized in the formulation
The known substance played with drug effect, is not particularly limited, the species and dosage of the auxiliary element can lead to according to pharmaceutical formulation
Simple experiment is crossed to determine to obtain.
Further, synergistic sterilizing composition of the invention can pass through the routine techniques hand of those skilled in the art
Section is prepared into any one formulation for being adapted to agriculturally use, including but not limited to missible oil, wettable powder, suspending agent, moisture
Shot agent, aqueous emulsion, microemulsion, granule etc..
Further, synergistic sterilizing composition of the invention can also include other active materials, such as insecticide,
One kind in attractant, herbicide, synergist, safener, fertilizer, biostimulant, plant growth regulator, semiochemical
Or it is several more than, or can with the present invention bactericidal composition be used in conjunction with.
Further, synergistic sterilizing composition of the invention can be provided in the form of finished product preparation, i.e., in composition
Each material has been adequately mixed and has been prepared into the dosage form for being adapted to use, and can also be used alone with unit dose preparation, uses
It is preceding voluntarily to be mixed in bucket or tank, and optionally mixed and be diluted with water according to the concentration of required active material.
Compared with prior art, synergistic sterilizing composition of the invention has the beneficial effect that：（1）The sterilization of the present invention
Interaction in composition between active component folpet and benzo alkene fluorine bacterium azoles is not simply to be superimposed, both compound after
Preventing and treating in certain scope to corps diseases shows obvious synergistic function, it is possible to reduce pesticide activity component makes
Dosage, improve prevention effect；（2）The active component mechanism of action differs in the bactericidal composition of the present invention, and both uses can be with
Increasing action site, overcome resistance, extend pesticide activity component service life；（3）The bactericidal composition of the present invention is pacified to crop
Entirely, to also being had no adverse effects beneficial to natural enemy.
Embodiment
