Weed Management

Weeds are defined as “plants out of place.” In agriculture, these are often pioneer species that are adapted to the disturbed conditions in a farm field, and many are exotic species without the natural biocontrols that may exist in their native habitat. CSANR has focused on weed control approaches that are more biologically based (e.g., grazing, crop rotation) and/or that are allowable for use on organic farms (e.g., tillage, mulching). Weed problems and weed control strategies vary greatly along with our varied climate and crops in the state.
