NOVELTY - A process (P1) of manufacturing a pesticide treated non-living material involving: impregnating the non-living material with an aqueous formulation free of organic solvents which comprises at least one pesticide (A), a polymeric binder (B) comprising at least one fluorinated polyacrylate having a fluorine content (based on the solid content of the polymeric binder) of at least 10 wt.%, and water as the sole solvent component (C).    USE - For impregnating non-living material such as textile material (claimed); for impregnation of fabrics and netting materials used for the protection of plants, protection men, animals and/or materials from harmful organisms; as mosquito-nets; for the protection of materials or objects e.g. buildings and premises (houses, streets) from harmful organisms; for protecting crops and/or harvested crops such as e.g. tobacco, tobacco bales or other tobacco products from harmful organisms during harvesting, drying, curing, transport and storage; and for protecting animals in corals and stables from insects and other pests such as mosquitoes, ticks, cockroaches, mites, fleas, lice, leeches, houseflies, and other flying and crawling insects.    ADVANTAGE - The method provides impregnating textile materials with pesticides which performed at ambient temperatures and which nevertheless yields a textile material in which the pesticide activity is maintained even after multiple washes; is economical and ecological method for impregnating textile materials that is not hazardous to workers in the production process or end users carrying out the impregnation before the first use. The impregnating textile materials provide mosquito-nets which can be washed several times without significant decrease in insect-controlling activity; protect crops and/or harvested crop such as e.g. tobacco, tobacco bales or other tobacco products from harmful organisms during harvesting, drying, curing, transport and storage, and avoid the necessity to treat such crops to be protected directly with pesticides or other chemicals.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an impregnated non-living material comprising at least a pesticide (A) and a polymeric binder (B) obtainable by the process (P1).
