Description
Technical field
The present invention relates to the pesticidal preparations field, particularly a kind of water dispersible granules that contains shitosan.
Background technology
Shitosan (chitosan) is that the chitin extensively existed by natural world obtains through deacetylation, and chemical name is Chitosan (1-4)-2-amino-B-D glucose; From 1859, after at first Frenchman Rouget obtains shitosan, the premium properties such as the biological functionality of this natural polymer and compatibility, blood compatibility, safety, microbic resolvability are by all trades and professions extensive concern, in the application study of the numerous areas such as medicine, agricultural chemicals, food, chemical industry, cosmetics, water treatment, METAL EXTRACTION and recovery, biochemistry and biomedical engineering, have obtained major progress.Especially in recent years, under the background of sustainable agriculture and the production of " nuisanceless " agricultural product, people are advantage as natural polymer from it more, take full advantage of its safety non-toxic, biodegradable and biocompatibility and unique physicochemical property and biologically active, become a hot fields in pesticide research.Japan have a lot of peasants by shitosan for crop production such as tomato, paddy rice, tealeaves, the commodity of use have " chitin first ", " organic club ", " crab ash " etc.
The structural formula of shitosan is as follows:
Molecular formula: (C

Shitosan is approved widely in the application of pesticide field, and is reached certain effect.
The wide spectrum biocide agent, the bactericidal action of shitosan comes from medical research, as the inflammation for the treatment of wound surface, athlete's foot, onychomycosis etc.Inspired by it, scientist has opened up its range of application on agricultural, finds that shitosan all has inhibition to spore germination and the mycelial growth of pathogenic, and uses the protection function that the pathogenic mattress is infected that inducing action is arranged.The scientific worker of the U.S., Japan, Russia, Canada, Korea S and China has utilized chitin and derivative thereof to prevent and treat the diseases such as wheat, barley, corn, soybean, paddy rice, vegetables, fruit at present, has obtained remarkable result.In (1998) such as Hanshous, with the generation that dosage is 1075, the seed dressing of the shitosan of 3712mg/kg has effectively suppressed bakanae disease of rice, relative control effect is more than 80%, and the inhibition of sclerotinia rot of colza is reached to 30%-50%.When chitosan oligomer that Jiang Yongming etc. (1999) are 1200,850 and 750 with mean molecule quantity is processed Colletotrichum gossypii, fusarium graminearum, Xanthomonas oryzae, Potato Ring Rot, cotton angular leaf spot fungus etc., find that it all has obvious inhibitory action to pathogen growth and breeding and fungus spore germination.Lai Fan etc. (1998) observe the impact of variable concentrations shitosan on the 16 Plants disease fungus growths such as fusarium graminearum, Rhizoctonia solani Kuhn, ash arrhizus bacteria, sweet potato soft rot bacterium, find that shitosan has certain inhibitory action to most of fungies wherein, and chitosan concentration increases, inhibitory action strengthens, but reaches the rear inhibitory action kept stable of finite concentration (30mg/mL).
The antibacterial agent bacterial diseases of plants is a kind of harm disease widely, often causes heavy losses in agricultural production.Yet conventional farm antibiotics drug effect is unstable, cost is high, the longevity of residure short (easily by edaphon and ultraviolet light degradation), pathogenetic bacteria easily produce the shortcomings such as resistance, and effect is unsatisfactory in actual applications.The bacteriostatic activity that shitosan has provides 1 new approach to the control of bacterial diseases of plants.Struszczyk minimal inhibitory concentration method, research shitosan and derivative thereof show the result of the pathogenic mutation in xanthomonas campestris India, the pathogenic mutation of pseudomonas syringae Kidney bean, the various bacteria effects such as pseudomonas syringae tomato pathogenic mutation, Agrobacterium tumefaciems and Escherichia coli: shitosan, in the 0.01%-0.3% concentration range, can suppress the growth of other several bacteriums except Escherichia coli.They further mix the injection tobacco leaf by the pathogenic mutation of pseudomonas syringae Kidney bean with chitin derivativ after, find that tobacco does not produce hypersensitivity, so they think that the antibacterial action of chitosan derivatives may be that it has hindered contacting of bacterium and tobacco cell wall, or have suppressed due to the existence of bacterium between tobacco cell.
Antiphytoviral, viroids agent, in agricultural production, crop virus type disease is all the vast plant protection work person's of puzzlement a difficult problem all the time.The scientific research personnel studies and finds that shitosan has the ability of Antiphytoviral, viroids, for the control of crop virus type disease provides a kind of new method.
Agricultural chemicals carrying agent and pesticide slow-releasing agent, shitosan is as a kind of natural macromolecular material, has safety non-toxic, the advantage such as biodegradable, can be used as the carrier of agricultural chemicals, is about to pesticide molecule be bonded on the shitosan macromolecular chain, reaches the low purpose that poisons of agricultural chemicals.Shitosan is owing to having amino, and some acid agrichemicals of bonding at an easy rate, as 2,4-drips, dicamba, 2 first 4 chlorine, maleic hydrazide etc.Chitin also can be as farm chemical carrier, and can effectively control the rate of release of agricultural chemicals in water.
Simultaneously, due to the good film forming of shitosan, adsorptivity and unique porous surface structure, can be made into agricultural chemicals the pesticidal preparations such as release membranes, spansule, sustained-release gel by the method coated or adsorb, control the rate of release of agricultural chemicals, increase safety and the lasting effect of agricultural chemicals.
Along with developing rapidly of green agriculture, how to reduce the use of chemical pesticide, how to strengthen the disease resistance ability of green plants, take biological products and measure, to strengthen plant self healthy growth mechanism be means, realizing ecological benign cycle, is the research focus of agriculture application in the world today.For many years, take fungi, bacterium, virus, nematode around day by day serious crops is main plant disease and to take insect, mite class be main insect pest problem, agricultural chemicals scientific research department take always and uses chemical pesticide as Main Means, although can reach certain control efficiency, but cause that plant self resistance against diseases goes down, generation and the well-known negative effect to human health and ecotope of causal organism and pest resistance, the scientific and reasonable use of chemical pesticide more and more is subject to people's attention.The sp act that shitosan or chitin show animals and plants and unique physical chemical property, will inevitably provide for the solution of above problem a new approach.
