## Abstract

A method for protecting crop plants from harmful organisms, which comprises 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The method as claimed in claim 1, wherein the material forming the meshed fabric is a synthetic or natural textile material, plastic material, a leather material, a flocked fabric, a sheeting, foil, a packaging material or a cellulose containing material.

### Claim 3 (depends on 1)

The method as claimed in claim 1, wherein the material is a netting.

### Claim 4 (depends on 1)

The method as claimed in claim 1, wherein the composition comprises (based on the total content of components A and B), 0.001 to 95 wt.-% of at least one pesticide, and 5 to 99.999 wt.-% of at least one polymeric binder.

### Claim 5 (depends on 1)

The method as claimed in claim 1, wherein the pesticide is selected from insecticides from the group consisting of pyrethroid compounds, carbamate compounds, organophosphorous compounds, sterilising compounds, nicotinic acetylcholine receptor antagonists, chlorine channel activators, juvenile hormone mimics, selective feeding blockers, mite growth inhibitors, microbial insecticides, inhibitors of oxidative phophorylation, uncouplers of oxidative phosphorylation, inhibitors of chitin biosynthesis, Ecdyson agonists and molting disruptors, Octopamine ergic agonists, coupling site II electron transport inhibitors, coupling site I electron transport inhibitors, voltage dependent sodium channel blockers, inhibitors of lipid biosynthesis, neuronal inhibitors, Aconitase inhibitors, N-arylhydrazine derivatives, synergists, Ryanodine receptor modulators, benzoximate, chinomethionat, dicofol, pyridalyl, borax, and tartar emetic; repellents, molluscicides, rodenticides, and fungicides.

### Claim 6 (depends on 1)

The method as claimed in claim 1, wherein the polymeric binder is an acrylic binder, obtained by radical polymerization of at least one monomer of formula II
wherein
R20, R21 and R22 are independently selected from C1- to C10-alkyl, which is optionally fluoro substituted and which may be linear or branched, or
R20 and R21 may further be H.

### Claim 7 (depends on 6)

The method as claimed in claim 6, wherein the C1- to C10-alkyl comprises methyl, ethyl, n-propyl, i-propyl, n-butyl, i-butyl, sec-butyl, t-butyl, n-pentyl, i-pentyl, sec-pentyl, neo-pentyl, 1,2-dimethylpropyl, i-amyl, n-hexyl, i-hexyl, sec-hexyl, n-heptyl, n-octyl, 2-ethylhexyl, n-nonyl, n-decyl; substituted or unsubstituted aryl, substituted or unsubstituted C6- to C10-aryl, substituted or unsubstituted C6-aryl, phenyl, or tolyl.

### Claim 8

A device for protecting plants from pests and diseases comprising a stabilizing structure and a meshed fabric, wherein 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 where 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; and curable polyesters
