Abstract
The invention discloses controlled-release pesticide granules prepared from natural or industrial and agricultural waste organic and inorganic materials and a bonder. The controlled-release pesticide granules are spherical or elliptical; a spherical body comprises a core layer and a wrapper layer; the core layer is made from a mixture of an organic matter, an inorganic matter and a pesticide active component; the wrapper layer is made from an organic material. The controlled-release pesticide granules are an environment-friendly product and can be widely applied to prevention and control of agricultural pests.
Description
Technical field
The present invention relates to a kind of sustained releasing pesticide granule and preparation method thereof, particularly, this sustained releasing pesticide granule in spherical shape or ellipsoid shape, spheroid divide sandwich layer and integument two-layer, sandwich layer is organic matter, inanimate matter and pesticide activity component mixture, and integument is organic material.Sustained-release pesticides preparation method of granules is: the absorption carrier of first preparation organic matter and inanimate matter mixing; Then, pesticide activity component is adsorbed on mixture carrier, with adhesive, above-mentioned organic matter and inanimate matter material is bonded into sandwich layer; Finally, the sandwich layer of preparation is wrapped up organic material and obtains integument, obtain sustained releasing pesticide granule.
This sustained releasing pesticide granule organic matter used, inanimate matter material and the adhesive overwhelming majority is natural materials or agriculture and industry waste, and prepared pesticide slow-release granule is environmentally friendly product, can be widely used in the control of agricultural pest.
Background technology
Sustained-release pesticides refers to according to damage by disease and insect pests occurrence rule, feature and environmental condition, is made agricultural chemicals dosage as required, specific time by manufacturing process, is discharged sustainedly and stably, to reach economic, safety, effectively disease and pest control object.Sustained releasing pesticide granule refers to and to be adsorbed in by pesticide original medicine on the organic and inorganic carrier of porous, wrap up with adhesive, adhesive is bonded into organic and inanimate matter raw material the particle of certain diameter simultaneously, final formation have necessarily wrap up intensity, can the granule of Co ntrolled release agricultural chemicals speed.Pesticide activity component in particle by dissolving, permeating and diffusion, slowly release, and rate of release can be controlled by regulating amount of binder, kind and a particle size etc.Sustained-release pesticides has following advantage: (1) the releasing dosage of sustained-release pesticides and time can control, and the functional of medicament is improved; (2) sustained-release pesticides is owing to there being the parcel of adhesive, and agricultural chemicals is degraded in the environment, loss speed reduces greatly, effectively can extend the lasting period of medicament, reduces the usage amount of agricultural chemicals; (3) sustained-release pesticides can Co ntrolled release, makes that high toxicity agricultural chemicals is low to be poisoned, and avoids or alleviate the pollution of high-toxic pesticide to environment.
Agriculturally sustained releasing pesticide granule used contains a large amount of chemical industry additive at present, if prolonged application is in farmland, certain risk can be caused to agricultural product security, the present invention is directed to this problem, large absolutely number material selection natural materials or agriculture and industry waste, the sustained releasing pesticide granule of preparation is environmentally friendly product.
Summary of the invention
Sustained releasing pesticide granule of the present invention, its feature is: be spherical or ellipsoid shape.Spheroid divide sandwich layer and integument two-layer, sandwich layer is inanimate matter, organic matter and pesticide activity component mixture, and integument is organic material.Sphere diameter: sandwich layer diameter is 1-20mm, integument thickness is 0.5-5mm.
Organic matter comprises: in straw, fowl and animal excrement, wood chip, sawdust, tobacco leftovers, Chinese herbal medicine offcuts, vinasse, bagasse one or more.
Inanimate matter comprises: in flyash, zeolite, clay brick powder, diatomite, bentonite, potter's clay, charcoal, opal, lime stone, dolomite one or more.
Adhesive comprises: sodium alginate, starch, gum Arabic, urea-formaldehyde glue, epoxy glue, hide glue, gelatine one or several.
Pesticide activity component comprises: the one in insecticide, bactericide, miticide, nematocide, weed killer herbicide or plant growth regulator or two or more.
Sustained releasing pesticide granule preparation method of the present invention, comprises the following steps:
(1) prepare absorption carrier, inanimate matter and organic raw material are dried respectively, pulverize, mixed as absorption carrier;
(2) pesticide activity component is adsorbed on carrier, pesticide active ingredient wiring solution-forming is sprayed on absorption carrier, and stirs, dry for standby;
(3) prepare sandwich layer, adhesive is melted into liquid state, be sprayed on the (2) prepared carrier containing pesticide activity component of step with Sprayable, sandwich layer be prepared into 1-20mm diameter particle by comminutor, dry for standby;
(4) prepare integument, adhesive is melted into liquid state, be sprayed on the (3) described sandwich layer of step with Sprayable, wrap up organic material, organic material thickness 0.5-5mm, dries and obtains pesticide slow-release granule;
The ratio of organic matter, inanimate matter in sustained releasing pesticide granule sandwich layer of the present invention, organic matter/inanimate matter is from 10/1 to 1/10, is preferably 5/1 to 1/5, then is preferably 2/1 to 1/2.
The present invention with organic and inanimate matter mixture for core, inanimate matter material hole is many, adsorptivity dose is large, but water proofing property is poor, organic materials adsorption is weaker than inanimate matter material, but water proofing property is relatively good, both mixing reach the effect of the absorption of balance agricultural chemicals and release, the organic material of sandwich layer outer wrapping one deck, further guarantee pesticide activity component slow releasing, in soil, reaches the result extending drug effect.
The present invention proves through overtesting, and slow-releasing granules can effectively extend the farm chemical release phase, reduces unit interval burst size, serves the effect of sustained-release pesticides active substance.
Raw material of the present invention easily obtain, and cost is low, and slow-releasing granules preparation method is simple, and suit large area to popularize use.
