Abstract
The invention discloses slow-release pesticide granules taking bentonite as a carrier. Based on the total weight of the granules, the slow-release pesticide granules comprise the following components: 0.1 to 50 percent of a pesticide active ingredient, 1 to 5 percent of a wetting dispersant, 0.1 to 2 percent of a bonding agent, 0.1 to 5 percent of a coating agent, and the balance of the bentonite. The invention further discloses a preparation method for the slow-release pesticide granules taking the bentonite as the carrier. The slow-release pesticide granules which can be released in a controlled manner can be prepared by taking the bentonite as a main carrier of the pesticide active ingredient and adding auxiliary agents, such as the wetting dispersant, the bonding agent and the coating agent. When the slow-release pesticide granules taking the bentonite as the carrier is used in a farmland, diseases, pests and weeds are prevented and removed, and meanwhile, soil can be improved, so that the use of a pesticide is environmentally friendly, and is beneficial to the sustainable development of modern agriculture.
Description
Technical field
The present invention relates to pesticide field, being specifically related to a kind of take wilkinite as pesticide slow-release granule and the preparation method of carrier.
Background technology
Chemical prevention is the important means that the mankind prevent and treat agricultural disease and pest, and the increasing both production and income ensureing agricultural is played a part extremely important by chemical pesticide. But environment is created very big negative impact by a large amount of frequently using of agrochemicals, causes soil acidification, hardens, and soil fertility seriously declines; Develop environment amenable pesticide formulation meaning very great.
Wilkinite take montmorillonite as the nonmetallic minerals of main mineral constituent, due to some positively charged ion of the laminate structure existence that montmorillonite structure cell is formed, such as Cu, Mg, Na, K etc., the effect of these positively charged ions and montmorillonite structure cell is very unstable, easily by other cationic exchange, therefore there is good ion exchangeable. External application in industrial and agricultural production 24 field 100 Duo Ge departments, is well suited for the carrier as pesticide slow-release granule. Can effectively improve soil while preventing and kill off farmland disease pest and weed so that the use of agricultural chemicals is more friendly to environment, improves soil productivity, make granular pesticide better serve agriculture production.
Summary of the invention
It take wilkinite as pesticide slow-release granule and the preparation method of carrier that the present invention provides a kind of, provides a kind of pesticide slow-release granule that environment is very friendly for preventing and kill off farmland disease pest and weed, can well improve soil electrolyte balance.
The present invention is achieved through the following technical solutions: a kind of take wilkinite as the pesticide slow-release granule of carrier, it is characterized in that: with granule total weight, wherein: pesticide activity component 0.1%-50%, wetting dispersing agent 1%-5%, binding agent 0.1%-2%, coating agent 0.1%-5%, wilkinite complements to 100%.
Wherein, described wetting dispersing agent be naphthalenesulfonate, sodium lauryl sulphate, pull open powder, the mixing of one or more in sodium lignosulfonate, calcium lignin sulphonate, alkylphenol polyoxyethylene, styroyl phenol polyethenoxy ether, succsinic acid sulfonate, Sodium dodecylbenzene sulfonate, polycarboxylate, fatty alcohol-polyoxyethylene ether.
Described binding agent is the mixing of one or more in polyoxyethylene glycol, dextrin, Xylo-Mucine, PVP, guar gum, xanthan gum.
Described coating agent is the mixing of one or more in polyvinyl alcohol, vinylformic acid formicester, Lauryl Alcohol fat, water-base resin, fatty alcohol.
The preparation method of a kind of pesticide slow-release granule taking wilkinite as carrier of the present invention:
(1) pesticide activity component, wetting dispersing agent, wilkinite are made after mixing laggard row comminution by gas stream the female powder of pesticide activity component;
(2) use female for pesticide activity component powder granulation, and use coating agent to carry out coated by layer, after dry, namely obtain pesticide slow-release granule.
It take wilkinite as pesticide slow-release granule and the preparation method of carrier that the present invention provides a kind of, uses and can improve soil while preventing and kill off disease pest and weed so that the use of agricultural chemicals is more friendly to environment, is conducive to the Sustainable development of modern agriculture in farmland.
