Description
Technical field
The invention belongs to technical field of pesticide, relate to composition pesticide, relate to a kind of bactericidal composition containing prothioconazoles and zarilamid specifically.
Background technology
In the whole process of growth of crop, be faced with the threat of the pests such as numerous such as disease, worm, grass, wherein disease, especially fungal disease, because it is of a great variety, complicated symptoms, propagation rapidly, the feature such as the serious and plyability generation of harm makes its difficulty of prevention and cure strengthen, and forms grave danger to crop yield and quality.In agricultural production process, in order to reduce the loss because fungal disease causes, chemical control is one of current comparatively significant means, but due to for a long time, unicity, continuity, repeatability etc. not Scientific Usage of Drugs means have caused many pathogens to produce resistance in various degree to the medicament of current use, and it is reported, due to this unscientific medication means, the resistance generation time of various medicament shortens year by year, causes the significantly increase of cost accounting, Environmental costs, medicament R&D costs.Based on this present situation, existing basis is improved effect of drugs for the comparatively cost-effective means that solve the problem.
Prothioconazoles (Prothioconazole) is a kind of New-type wide-spectrum triazolinthione series bactericidal agent of Beyer Co., Ltd's development, and be mainly used in preventing and treating numerous disease such as cereal, wheat class legume crop, its structural formula is as follows:
Prothioconazoles toxicity is low, and the mechanism of action is the demethylation effect of precursor one by one on lanosterol or the liquor-saturated l4 position of 24-methylene dihydro Mi hair of sterol in Antifungi, i.e. demethylation inhibitors (DMIs).Not only there is good systemic activity, excellent protection, treat and root out activity, and the lasting period is long.By a large amount of field control effectiveness tests, result shows that prothioconazoles not only has good safety to crop, and preventing disease theraping effect is good, and volume increase obviously, and compare with triazole type biocide agent, the sterilization that prothioconazoles has more wide spectrum is lived.Prothioconazoles is mainly used in control cereal crop as numerous diseases such as wheat, barley, rape, peanut, paddy rice and legume crops.Almost there is good control efficiency, as the powdery mildew, banded sclerotial blight, fusarium wilt, leaf spot, rust, stalk break, net blotch, moire disease etc. of Wheat and barley to all wheat class diseases.The soil-borne disease of oily Lay and peanut can also be prevented and treated, as stalk break, and main foliage disease, as gray mold, black spot, brown spot, balck shank, stalk break and rust etc.
Zarilamid system by Japanese agricultural chemicals company and BASF AG (former American Cyanamid Company) at nineteen ninety-five joint development successful inner sucting conduction type rice blast pesticide control.Invented by former cyanamide company the earliest.Zarilamid is a novel systemic fungicide for preventing and treating rice blast.There is novel mechanism of action, belong to melanin biosynthesis inhibitor (MBI), prevent and treat rice blast excellent on blade face with when using under water, and holding effect is remarkable.Be mainly used in preventing and treating rice blast, comprise leaf pest and Miho pest, best spraying time should at premorbid 7-10 days, or before heading 5-30 days.Filling is executed dosage and is generally 2100-2800ga.i./hm, cauline leaf process, and using dosage is 200-400ga.i./hm.Pest.Mixed with protective fungicide, downy mildew of garpe, potato and tomato late blight can be prevented and treated.
The combination of active principles of different agricultural chemicals is made agricultural chemicals, is current development novel pesticide and the one of preventing and treating agriculturally resistance germ effectively and efficiently mode.After the pestsides synthesis of different cultivars, usually show three kinds of type of action: summation action, synergistic effect and antagonism.Compound synergic is well filled a prescription, and can significantly improve actual control efficiency, and reducing the usage amount of agricultural chemicals, thus delay the drug-fast generation speed of germ widely, is the important means of integrated control disease.
Synergistic bactericidal composition not only can improve preventive effect greatly, reduces dosage, reduces costs, and phytopathogen can also be avoided to produce the generation speed of resistance and delaying drug resistance simultaneously, be solve current agricultural chemicals alone time resistance and a kind of effective means of Cost Problems.Therefore, develop and have the bactericidal composition of synergistic effect significant to fungal disease.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the invention is to overcome the dosing that above-mentioned single bactericide exists large, environmental pollution is serious, germ resistance produces the shortcomings such as speed is fast and provide a kind of efficient, safe bactericidal composition containing prothioconazoles.Under optimal proportion, composition has notable synergistic effect, ensureing the usage amount reducing medicament under optimum preventive effect, reducing costs, reducing the harm to environment, and is of value to and delays the drug-fast generation of germ.
