Description
Technical field
The present invention relates to a kind of agricultural bactericidal composition that contains ZJ0712, be specifically related to a kind of bactericidal composition that is used to prevent and treat powdery mildew on greengrocery, melon and fruit class, fruit tree, the flowers crop or downy mildew.
Background technology
Bactericide is a medicament (B.C. more than 1000 years) the most ancient on the human history, from sulphur, lime sulfur, bordeaux mixture, mercurial, to methoxy benzoic acid class, the aminopyrimidine of today.Its evolution is as follows: inorganic fungicide-＞the organic sulfur class-＞benzimidazole-＞triazole type-methoxy acrylic acid class.From organic sulfur to methoxy acrylic acid class is the three great revolutionary movements the bactericide evolution.
In preceding 50 pesticide species of world's ranking, 10 in bactericide (20%), 2 of methoxy acrylic acid classes, 2 of triazole type, 1 of benzimidazole, generation 1 of gloomy class, other are sulphur.
New product and traditional product respectively account for 5, front three and last 2 kinds for developing or really introduced to the market in recent years.5 new varieties sales volumes are 14.01 hundred million dollars altogether, account for totally 10.04 hundred million dollars of 58.25%, 5 traditional categories of these 10 bactericide total values (24.05 hundred million), only account for 41.75%.These 10 bactericide account for 44.13% of bactericide market, the world, and two methoxy acrylic acid classes account for 16.15% of bactericide market, the world.
Bactericide kind newly developed in recent years, methoxy acrylic acid series bactericidal agent are big milestones in the bactericide field, have formed new bactericide kind series.Methoxy acrylic bactericide has unique mechanism of action, and it stops the ATP of cell synthetic by the electronics transmission of pinning between cytochrome b and the c1, thereby suppresses its mitochondrial respiratory and bring into play bacteriostasis.The bacterial strain that 14-demethylation enzyme inhibitor, benzamides, dicarboxylic dihydrazides amine and benzimidazole is produced resistance is effective.Have protection, treat, root out, infiltration, systemic activity, and can be in plant corpus, very fast degraded in soil and the water.Although this series bactericidal agent mechanism of action uniqueness, but pathogen is also very fast to the speed that it produces resistance, the use cost height, so the large tracts of land of restriction methoxy acrylic acid series bactericidal agent is promoted the use of, therefore the bactericide combination of the methoxy acrylic acid series bactericidal agent and the another kind of mechanism of action is composite, improve drug effect, slow down the generation of resistance, reduce usage amount, enlarging using of this medicament is present urgent problem.
ZJ0712 is that country's the enforcement period of the ninth five-year plan is by the methoxy-methyl acrylate compounds of finding in the Zhejiang Provincial Chemical Engineering Research Inst initiative study on the synthesis place novel pesticide initiative process with efficient sterilizing activity; have protection and therapeutic action; this medicament has good biologically active to diseases such as the powdery mildew on the crop, downy mildew, anthracnose, can be used as the bactericide of melon, fruit tree, vegetables, wheat, tobacco, flowers and other crops.Now applied for national patent number: ZL 03120882.7 and world inventions patent, its patent No. is: W020004084632, and finished control crop powdery mildew and downy mildew are registered field experiment temporarily.But do not see combination patent report with protective fungicide Carbatene, Propineb, zineb.
The English common name metriam of Carbatene, two (the two thiocarbamate esters) zinc (2+) of chemical name three [ammonia] ethene)] [8-connects dithione for tetrahydrochysene-1,4,7-two thiophene diazocines-3], polymer.Carbatene is a kind of good protective fungicide, belongs to low-toxin farm chemicals.Because wide, the difficult resistance that produces of its bactericidal range, control efficiency obviously is better than other same series bactericidal agents, so consumption is a large tonnage product in the world always.Be the substitute products of present other protective fungicides; domestic most composite bactericide is all formulated with mancozeb processing; but the MnZn preparation can cause the crop trace element accumulation and poison; by field application in recent years, remarkable to preventing and treating effects such as pear scab, alternaria leaf spot of apple, vegetable category eqpidemic disease, downy mildew, field crop rust.
The English common name propineb of Propineb, molecular formula (C
