Technical field
The present invention relates to a kind of bactericidal composition and uses thereof, especially a kind of is the bactericidal composition and the application thereof of main active with prochloraz-manganese chloride complex and mancozeb.
Technical background
Prochloraz-manganese chloride complex is the imidazoles broad-spectrum germicide.The various crop disease that causes for sac fungi and imperfect fungus has special efficacy.Cause effect by the biosynthesis that suppresses sterol.Though do not have a systemic action, it has certain conductive performance.
The controlling object of prochloraz-manganese chloride complex has citrus anthracnose, blossom-end rot, penicilliosis, green mould, banana anthracnose, leaf spot, mango anthracnose, leaf spot of peanut, vegetables anthracnose such as capsicum, eggplant, muskmelon, tomato, strawberry anthracnose, bakanae disease of rice, rice blast, sclerotinia rot of colza, leaf spot, mushroom brown spot, apple anthracnose, pear scab etc.
Mancozeb is the wider protective fungicide of fungicidal spectrum, mainly is the oxidation that suppresses pyruvic acid in the thalline, and is effective to multiple diseases such as the anthracnose on fruit tree, the vegetables, early blight.
In the real process of agricultural production, preventing and treating the problem that disease is easy to generate most is the drug-fast generation of germ.Anthracnose is the modal diseases of oranges and tangerines, it has the advantages that harm is wide and the harm time is long, main harm blade, branch, flower, fruit and carpopodium often cause that oranges and tangerines kinds such as tangerine and orange class are fallen leaves in a large number, branch is withered, a large amount of fallen flowers, shedding and fruit rot.In the suitable area of condition, can endanger oranges and tangerines throughout the year.Prevent and treat this disease mainly based on chemical control.Because resistance problem, medicament commonly used such as carbendazim, thiophanate-methyl, mancozeb etc. can't effectively be controlled spreading of this disease.Efficient medicament such as Prochloraz, prochloraz-manganese chloride complex, Difenoconazole has been used in a lot of places in a large number, because long-time, large-area application, the efficient medicament of this class also faces the risk that pesticide resistance produces.
Preventing and treating disease with the novel pesticide that does not have cross resistance is a good solution.But, develop a novel pesticide at present and need screen 1 ten thousand-1.2 ten thousand compound, expensive 1.2-1.5 hundred million dollars, the construction cycle is 5-10 years, is difficult to catch up with the speed that pathogen produces resistance.Other method such as crop allocation adjustment, different agricultural chemicals are rotated etc., in the process of practical operation, are difficult to really play obvious effects.
