The USDA-ARS in Wooster, Ohio, has begun a new five-year research program to develop weed management options for herbicide-sensitive crops.

A very promising part of this project thus far has been the use of parboiled rice hulls as a mulch in containers. Riceland Foods, Inc. has been marketing their parboiled rice hulls for weed management in horticulture crops, and some nursery producers in Ohio have already successfully used rice hulls for weed control.
