Abstract
The invention relates to a method for preventing and treating septoria lycopersici and brown rust of wheat and rust of soybeans. A sterilization composition containing pyraclostrobin and xemium acts on pathogenic bacteria and/or an environment thereof or plants, plant parts, seeds, soil, regions, materials or spaces. The weight ratio of the pyraclostrobin to the xemium is (100:1)-(1:100). The invention also relates to a method for protecting wheat seeds and soybean seeds. The method for protecting the wheat seeds and the soybean seeds comprises a step of enabling seeds to touch a synergetically effective amount of composition containing the pyraclostrobin and the xemium before sowing seeds and/or after accelerating germination. The invasion of the septoria lycopersici, the brown rust and the rust can be prevented by treating the seeds.
Description
Technical field
What the present invention relates to is a kind of method of preventing and treating wheat spot blight and leaf rust, soybean rust.
Background technology
Fungicide is natural or the compound in synthetic source, it is not caused by fungi for the protection of plant infringement.Present agricultural methods depend critically upon use fungicide.In fact, some crops can not be in the situation that do not use fungicide effectively to grow.Use fungicide to allow that the grower increases the quality of output and crop, and the value that increases thus crop.In most cases, the value added that is worth of crop is at least three times of the cost of using fungicide.
But there is no a kind of fungicide is all useful in all cases, and reuses single fungicide of planting and usually cause this kind or relevant fungicide are produced drug resistance.Therefore, researching and producing more safely, having the lower fungicide of better performance, dosage that need to be lower, easy use and expense and the composition of fungicide.
Pyraclostrobin (Pyraclostrobin), have another name called pyraclostrobin, and its chemical name is: methyl (N)-[[[1-(4-chlorobenzene) pyrazoles-3 base)-oxygen]-the 0-methoxyl group]-the N-methoxymethyl carbamate, its structural formula is:
Pyraclostrobin is the same with the mechanism of action of other synthetic strobin analog, is a kind of mitochondrial respiratory inhibitor.It, by stoping electronics transmission between thin race pigment b and C1 to suppress the mitochondrial respiratory effect, makes mitochondria can not produce and provide the needed energy of cell eubolism (ATP), finally causes cell death.Pyraclostrobin has stronger inhibition germ spore germination ability, and mycelial growth in blade is had good inhibitory action. and its lasting period is longer, and has potential therapeutic activity.This compound is in blade a little less than the conduction of blade tip or phyllopodium and fumigation action, but the conduction activity in plant corpus is stronger.It is again a kind of hormone-type bactericide simultaneously, can make the more nitrogen of Crop, promotes the growth of crop.In a word, pyraclostrobin has protective effect, therapeutic action, interior suction conductivity and resistance of rainwater washing against performance, and range of application is wider.
The suitable crop of pyraclostrobin is mainly used in preventing and treating wheat, paddy rice, peanut, grape, vegetables Lay, banana, twists the disease on lemon, coffee, fruit tree, walnut, vegetables, tea tree, tobacco and ornamental plants, lawn and other field crops.Controlling object can be prevented and treated effectively by multiple diseases such as the fungus-caused leaf blight of Ascomycetes, Basidiomycetes, Fungi Imperfecti and Oomycete, rust, powdery mildew, downy mildew, epidemic disease, anthracnose, scab, leaf spot, shot hole, brown spot, damping offs.Pyraclostrobin control cereal disease, due to the bactericidal activity with wide spectrum, has outstanding control efficiency to the leaf section of cereal and the disease of fringe grain, and obvious effect of increasing production.Not only toxicity is low to this compound of crop safety, to non-target organism safety, and also all friendly safely to user and environment.Under recommendation dosage, most result of the tests showed crop without poisoning, but extremely indivedual fox grapes and plum kind are had poisoning in a certain vegetative period.
Fluorine azoles bacterium acid amides (fluxapyroxad), commodity are called Xemium, belong to acid amide fungicides, it is BASF AG finds in the process that Boscalid is further optimized bactericide, make up the deficiency of Boscalid, have good therapeutic action, and range of application has been extended to intertillage crop.Research shows, Xemium has better activity than commercially available acid amide fungicides, and no matter this product is active, multi-functional, or at aspects such as interior absorption and resistance of rainwater washing against, is all that modern fungicides has been set up new mark post.Its mobility unique in plant makes it have lasting preventive and therapeutic action, thereby cover crop exempts from infecting of fungal disease, is mainly used in soybean, wheat and peanut and other crops.
Summary of the invention
The objective of the invention is provides a kind of method of preventing and treating wheat spot blight and leaf rust, soybean rust for above-mentioned weak point, provides harmful fungoid is had good effect and solved the depressant dose rate and/or agricultural methods and the composition of the problem of enhanced activity spectrum and/or drug resistance management.
Another object of the present invention is to improve the composition of plant health.More healthy plant is desirable, because they produce higher fruit output and plant or the fruit quality of Geng Gao.This further provides to reduce the possibility of needed reactive compound amount in agricultural and help avoid each agricultural chemicals and has developed immunity to drugs.
