    摘要: A method for reducing the rate of diffusion of a slow-release material through a host polymer material to increase the useful life of a slow-release product. An inert fine particulate inorganic material such as an intercalation material having a layered structure is incorporated into a mixture of the slow-release material and the host polymer. The intercalation material has its layers intercalated with molecules of the slow-release material which are accommodated within spaces between the layers of the intercalation material. The particulate material slows the diffusion rate of the slow-release material through the host polymer when compared with the diffusion rate of the same slow-release material through the same host polymer not containing the particulate material. In one embodiment, the intercalation material comprises a nano-clay, the host polymer is a polyolefin, and the slow-release material is a bioactive material such as dinitroanaline. The slow-release product can comprise a drip irrigation emitter device or tube or tape or device used adjacent to an emitter to protect against root intrusion. The intercalation material can comprise a layered nano-clay produced by contacting the clay with a surface modifier to achieve sorption and complexing of the surface modifier between adjacent spaced layers of the clay material, sufficient to expand the spacing between adjacent platelets. This is followed by exfoliating the surface-treated material to separate the platelets, followed by mixing the exfoliated platelets with the polymeric material to form a polymeric matrix from which drip irrigation products can be made.

    摘要: In an agricultural chemicals composition which is scattered by being thrown directly into a submerged paddy field, it is an object to provide a composition having an excellent spreadability without stagnation of an agrochemically active ingredient at the point of treatment (application), and in particular to provide a labor-saving formulation for scattering (application) which contains a liquid agrochemically active ingredient at room temperature, and to provide an agricultural chemicals composition containing a liquid agrochemically active ingredient at room temperature in high concentrations, which have been difficult to be realized. The agricultural chemicals composition prepared by letting a granular nucleus coated with a water-soluble polymer or water-swellable substance hold agrochemically active ingredients and, if necessary, surfactants, and a method of scattering (applying) a granular agricultural chemicals formulation comprising the step of throwing the agricultural composition directly into a submerged paddy field at a rate of 20 g to 2,000 g thereof per 10 are of the paddy field, or packing 10 g to 100 g of the agricultural chemicals composition per bag made of a water-soluble film and throwing directly into a paddy field at a rate of 2 to 20 bags per 10 are.
