The invention relates to a method for producing supports based on zeolites and other inorganic molecular sieves for the controllednemission of semiochemicals, with application to the environmental combat against agricultural plagues. The process is based on thenmodification of one or a plurality of the physico-chemical characteristics of zeolitic supports: Si/Al ratio, acidity, compensation cations andnpore size, as well as the compaction pressure and relation between the surface and the weight of the conformed material, with the objectnto regulate the absorption force and the further controlled and extended emission of the semiochemicals. |
