Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of bactericidal composition on crop pest that contains dithianon and prochloraz-manganese chloride complex.
Technical background
Dithianon (dithianon) is the bactericide of BASF European Co.,Ltd's exploitation, and pure product are dark-brown crystalloid solid.Molecular formula is C

2, chemical name is: N-propyl group-N-[2-(2,4, the 6-Trichlorophenoxy) ethyl]-1H imidazoles-1-formamide-manganese chloride.
Prochloraz-manganese chloride complex works by the biosynthesis that suppresses sterol, although it does not have systemic action, but has certain conductive performance, mushroom brown rot, mango anthracnose, oranges and tangerines penicilliosis, anthracnose there is special control efficiency, also can be used for fruit and adopt post processing, control storage period disease.In soil, mainly be degraded to volatile metabolite, easily adsorbed, be difficult for being dashed pouring,, but the fungi in some soil is had inhibitory action the biological low toxicity in the soil by soil by soil particle.
No matter be dithianon, prochloraz-manganese chloride complex or other efficient germicides, long-term use separately makes disease develop immunity to drugs easily, causes the problem that dosage strengthens, preventive effect reduces, the lasting period shortens, and is unfavorable for environment sustainable development.The active ingredient of the different mechanisms of action is carried out composite, is to delay the disease method commonly used that develops immunity to drugs, and according to the effect in the production application, judge this composite be synergistic effect or antagonism.Complex role is more significantly filled a prescription, and can obviously improve preventive effect, reduces the dosage of agricultural chemicals greatly, also can enlarge fungicidal spectrum, improves germicidal efficiency.Dithianon is different with the prochloraz-manganese chloride complex mechanism of action, and mutually composite have good synergistic effect within the specific limits.And composite about dithianon and prochloraz-manganese chloride complex do not see relevant report at present at home and abroad as yet.
