Description

Oligosaccharides and sulphur are as the agriculturally useful compositions of building component
Technical field
The invention belongs to plant protection art, particularly relate to oligosaccharides and sulphur as the agriculturally useful compositions of building component and preventing and treating the application in agricultural pest.
Background technology
In agricultural production, the pesticide resistance of crop disease and insect to Pesticidal products strengthens gradually, and, the damage by disease and insect of same crop often occurs simultaneously, peasant often attends to one thing and lose sight of another when independent pest control or disease, not only delays work and misses control opportunity, from and strengthen dosage etc.Due to single and not Scientific Usage of Drugs, cause that peasant's cost improves, the destruction etc. of environmental pollution and ecotope.Carrying out composite with different structure, the different mechanism of action, environmentally friendly active component, and rationally add auxiliary agent and make new agriculturally useful compositions, is reduce and delaying drug resistance insect, expanding prevention target, improve the effective way of drug effect, minimizing environmental pollution.
Sulphur is an important kind in inorganic pesticide.Commodity are yellow solid or powder, have obvious smell, can volatilize.Sulphur aqueous suspensions is subacidity, water insoluble.Sulphur belongs to multipurpose agent, apart from outside bactericidal action, can also kill mite, desinsection, have fertilizer efficiency, to people, animal safety, not easily makes crop produce poisoning.
Oligosaccharides is the bioactivator with specific aggregation degree obtained through special biological enzyme technology process by glycan, its molecular weight is lower, better water-soluble, easily absorbed by organism, there is special biologically active, there is the function of diseases prevention, disease-resistant, regulating plant growth, utilize the oligosaccharides of separate sources can specific aim exploitation series of oligosaccharides biopesticide.
