Claims8
A method for protecting crop plants from pests and diseases, comprising the step of covering one or more of the plants with a device, comprising a stabilizing structure and a meshed fabric, where the meshed fabric is impregnated with a pesticide and is penetrable by light, air and water,
- wherein the material forming the meshed fabric is treated with a composition comprising:
- a. at least one pesticide (component A), and
- b. at least one polymeric binder (component B),
- and wherein the polymeric binder (B) is selected from the group consisting of polyacrylates, polymethacrylates, polyacrylonitrile, polymaleic acid anhydride, polymaleic acid, polymaleic acid esters, and polymaleic acid amides, polystyrene, poly(methyl)styrene, polybutadiene, polyvinylacetate, polyvinylalcohol, copolymers obtained by polymerization of at least two different ethylenically unsaturated monomers of the group of monomers mentioned above and blends of said homopolymers and/or copolymers, poly(styrene-acrylates), poly(styrene-butadiene), ethylene-acrylate-copolymers, ethylene-vinylacetate-copolymers, which may be partially or completely hydrolyzed, polyurethanes and/or or polyisocyanurates, blends comprising polyurethanes and/or polyisocyanurates, blends comprising polyurethanes and/or polyisocyanurates and polycarbonates;
- mineral waxes, zirconium waxes, silicones, polysiloxanes, fluorinated polyacrylates and methacrylates, fluorosilicones, and fluorocarbon resins, melamine formaldehyde condensation resins, methylol urea derivatives;
- curable polyesters;
- and
- blends or preparations comprising at least one of said polymeric binders;
- and where the stabilizing structure comprises one or more poles, one or more clamp like structures or a framework to which the mesh material is allocated in order to form a closed interior.
