The non-volatile pesticides are released in an amount to provide a concentration of between about 500 grams/hectare and about 5000 grams pesticides per hectare of soil. ## Claims ### Claim 1 A pesticide-containing soil disinfestation material comprising: i) a polymer composite material having a first face and a second face opposite to the first face; ii) a coating material coating a portion of the first face of the polymer composite material, the coating material comprising at least one water soluble polymer; and iii) at least two non-volatile pesticides incorporated in the coating material; wherein the coating material is not cross-linked, does not contain a hardener, and is configured to release the at least two non-volatile pesticides in an amount to provide a concentration of between about 1000 grams and about 5000 grams of pesticides per hectare of soil; and wherein lateral edges on the first face of the polymer composite material are uncoated, a width of the uncoated lateral edges being sufficient to allow handling of the pesticide-containing soil disinfestation material without exposure of an operator to the coating material. ### Claim 2 (depends on 1) The pesticide-containing soil disinfestation material of claim 1, wherein the coating material is configured to release the at least two non-volatile pesticides in an amount to provide a concentration of between about 1500 grams and about 5000 grams of pesticides per hectare of soil. ### Claim 3 (depends on 1) The pesticide-containing soil disinfestation material of claim 1, wherein the polymer composite material comprises one or more of non-biodegradable polyethylene or a biodegradable polyester. ### Claim 4 (depends on 3) The pesticide-containing soil disinfestation material of claim 3, wherein the polyethylene is selected from linear low density polyethylene, low density polyethylene and high density polyethylene. ### Claim 5 (depends on 4) The pesticide-containing soil disinfestation material of claim 4, wherein the polyethylene is a mixture of two or more of low density polyethylene, linear low density polyethylene and high density polyethylene. ### Claim 6 (depends on 3) The pesticide-containing soil disinfestation material of claim 3, wherein the biodegradable polyester is selected from polybutylene adipate terephthalate, polylactic acid polybutylene succinate, polybutylene succinate, a mixture of polybutylene adipate terephthalate with polylactic acid and a mixture of polybutylene adipate terephthalate with polybutylene succinate. ### Claim 7 (depends on 1) The pesticide-containing soil disinfestation material of claim 1, wherein the polymer composite material further comprises one or more of a UV stabilizer, UV absorber, and IR absorber. ### Claim 8 (depends on 1) The pesticide-containing soil disinfestation material of claim 1, wherein the polymer composite material is metalized. ### Claim 9 (depends on 1) The pesticide-containing soil disinfestation material of claim 1, wherein the coating material comprises at least one coating layer. ### Claim 10 (depends on 9) The pesticide-containing soil disinfestation material of claim 9, wherein the at least one coating layer is a pesticide reservoir coating layer. ### Claim 11 (depends on 1) The pesticide-containing soil disinfestation material of claim 1, wherein the coating material comprises at least two coating layers. ### Claim 12 (depends on 11) The pesticide-containing soil disinfestation material of claim 11, wherein a first coating layer is a pesticide reservoir coating layer and a second coating layer is a protective coating layer. ### Claim 13 (depends on 1) The pesticide-containing soil disinfestation material of claim 1, wherein the coating material comprises three coating layers. ### Claim 14 (depends on 13) The pesticide-containing soil disinfestation material of claim 13, wherein a first coating layer is a pesticide reservoir coating layer, a second coating layer is a protective coating layer and a third coating layer is a water equalizing coating layer. ### Claim 15 (depends on 1) The pesticide-containing soil disinfestation material of claim 1, wherein the coating material comprises gelatin. ### Claim 16 (depends on 1) The pesticide-containing soil disinfestation material of claim 1, wherein the coating material comprises gelatin and a water soluble polymer binder. ### Claim 17 (depends on 1) The pesticide-containing soil disinfestation material of claim 1, wherein the coating material does not comprise a superabsorbent polymer. ### Claim 18 (depends on 1) The pesticide-containing soil disinfestation material of claim 1, wherein the at least two non-volatile pesticides are selected from an herbicide, a fungicide, an insecticide and a nematicide. ### Claim 19 (depends on 1) The pesticide-containing soil disinfestation material of claim 1, wherein the polymer composite material has a thickness ranging between about 10 μm and about 250 μm, or between about 10 μm and about 150 μm, or between about 20 μm and about 120 μm, or between about 20 μm and about 50 μm, or between about 0.075 μm and about 150 μm or between about 150 μm and about 500 μm. ### Claim 20 (depends on 1) The pesticide-containing soil disinfestation material of claim 1, wherein the coating material has a thickness of less than about 12.5 μm, or less than about 6 μm, or less than about 3.0 μm, or less than about 1.5 μm, or less than about 0.75 μm. ### Claim 21 (depends on 1) The pesticide-containing soil disinfestation material of claim 1, wherein the polymer composite material is a film. ### Claim 22 (depends on 1) The pesticide-containing soil disinfestation material of claim 1, wherein the coating material comprises: i) a first coating layer comprising a gelatin and sodium polyacrylate;
