SUSTAINED RELEASE SYSTEM FOR THE INTEGRATED MANAGEMENT OF AGRICULTURE AND LIVESTOCK PESTS, FOREST PESTS AND URBAN PESTS

摘要

The invention relates to a system for the sustained release of semiochemicals, characterised in that it is a composite material made up of a continuous phase and a disperse phase, for use in the integrated management of agricultural pests, livestock pests, forest pests and urban pests. In the composite material of the sustained release system, produced at a temperature below 55°C, the continuous phase can be a hydrophobic gel or an oil of a range of viscosities obtained by the addition of a series of thickeners, gelling agents or viscosity modifiers, and the disperse phase consists of a support with a porous or cross-linked structure, which can be an organic cross-linked polymer or an inorganic sorbent. The example of application of the sustained release system involves semiochemicals that attract A. obliqua fruit flies, and the material comprises, in weight percentage: a) at least 13.0 to 25.0% of a disperse polymer phase; b) food preservatives such as benzoate and potassium sorbate, each one amounting to between 0.15 and 3.0%; c) between 0.15 and 3.0% of any food colouring agent; d) a semiochemical; and e) the continuous phase which amounts to between 13.0 and 26%. The invention relates to the composite material, to the sustained release system, to the use thereof with semiochemicals and insecticides, and to the production method carried out at a temperature below 55°C.
