The composition can be used for preventing and curing plant diseases, the plant diseases can be prevented and cured, and various resistance of plants can be improved, so that the plants can grow robustly, the yield is improved, and the quality is improved; and the composition is used for sterilizing and preserving fruits, and the effect is good, and the usage amount of chemical pesticides is further reduced.
Description
Technical field
The present invention relates to a kind of complex composition that contains chitosan oligosaccharide and Prochloraz, belong to pesticide field.
Background technology
Chitosan oligosaccharide also is chitin, chitosan, amino-oligosacchride etc., be a kind of from some halobiontic crusts such as dried small shrimp, crab shell, extract have a multiple bioactive active substance.All be rich in chitin in a lot of halobiontic crusts, chitin is through deacetylated generation shitosan, and shitosan resolves into easily through enzymolysis or microwave treatment etc. and is absorbed by tissue, water miscible chitosan oligosaccharide.Studies show that in recent years, chitosan oligosaccharide have multiple biological function and are used gradually, comprising health care of food, beauty and skin care, bacteriostasis, preservation, induction of resistance etc.Aspect agriculture application study, find to use low polymerization degree, high deacetylated chitosan oligosaccharide to have obvious germ and suppress activity, plant disease-resistant induced activity etc., particularly respond well to plant virus venereal disease evil, therefore can be applied to the control of plant disease; Because chitosan oligosaccharide is macromolecular compound, is easy to form polymeric membrane, self there is again certain restraining and sterilizing bacteria active, therefore, the chitosan oligosaccharide aqueous solution soaks fruit and has good bacteriostasis, preservation effect, and nontoxic residue-free can be used as the keeping-freshness storage that antistaling agent is applied to fruits and vegetables; After chitosan oligosaccharide is administered to plant, but the internal metabolism of regulating plant also, excite plant corpus to produce the resistance materials such as protective plant protecting agent, polyhydric phenols, improve disease-resistant, the drought resisting of plant, the resistance such as cold-resistant, make plant growth healthy and strong, improve output, improve quality etc., play plant growth regulating and improve the effect of nutrition.
Prochloraz is a kind of imidazoles broad-spectrum germicide, bactericidal action is played in the biosynthesis of the ergosterol by suppressing mushroom, have excellent protection, treatment and shoveling function, the plurality of plant diseases that sac fungi, imperfect fungus etc. is caused has good control efficiency, is bactericide commonly used in a kind of agricultural production; The Prochloraz fungicidal spectrum is wide, and toxicity is low, and the lasting period is longer, also is widely used in the keeping-freshness storage of the fruits and vegetables such as oranges and tangerines, banana.
Other patent application such as application number are that 201210200540.5 Chinese invention patent application discloses a kind of bactericidal suspending agent that contains oligosaccharide element, prochloraz, but the equal Shortcomings part of its composition proportion and effect.
Summary of the invention
Technical problem to be solved of the present invention, a kind of complex composition that contains chitosan oligosaccharide and Prochloraz is provided, this composition can be used for preventing and treating the plurality of plant diseases such as anthracnose, simultaneously can make the plant growth stalwartness by improving plant resistance to environment stress (disease-resistant, drought resisting, cold-resistant etc.) again, improve output, improve quality, can be used for again the keeping-freshness storage of fruits and vegetables, not only antibacterial, sterilization, good refreshing effect can also reduce the use of chemical pesticide.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is: a kind of composition that contains chitosan oligosaccharide and Prochloraz, its active ingredient are chitosan oligosaccharide and Prochloraz, and its quality proportioning is 1-4:41-50, and the active ingredient quality proportioning of optimization is 1-3:44-45; The optimum quality proportioning is 1:45.Described chitosan oligosaccharide degree of polymerization 3-10, deacetylated rate is more than 90%, and described Prochloraz raw material is that purity is at the routine raw material of the market more than 95%.
Above-mentioned composition is used the conventional pesticide process technology, can be made into the formulation of using on the multiple suitable agricultural, preferred dosage form has aqueous emulsion (EW), microemulsion (ME), aqueous suspension agent (SC), wetting powder (WP), missible oil (EC) etc., adds other auxiliary agent except active ingredient of using man-hour, filler etc. and is the industry and commonly uses composition.
Composition of the present invention, have obvious action compensating and synergistic effect, plurality of plant diseases not only had well antibacterial, sterilization, disease cure function, can also produce the multiple resistance material by inducing plant, improve disease-resistant, the resistance of plant, make plant growth healthy and strong, improve output, improve quality, reduce the usage amount of chemical pesticide, alleviate environmental pressure; The keeping-freshness storage that also can be used for fruit, vegetables, and improve the sterilization fresh-keeping effect.
