Abstract
This invention relates to a mulch having a preprogrammed biodegradability comprising at least two different layers of biodegradable polymer coated onto a sheet of a cellulosic material, one of these layers being a layer of polylactide. The mulch is particularly useful to control weeds in agriculture, horticulture, and forestry industries. The biodegradability of the mulch can further be preprogrammed according to the type of soil, the climatological zone, and the specific applications wherefore it is intended to be used. The present invention is also directed to methods for preparing and using the multilayer coated mulch.
