Weed Identification and Control Databases

There are two searchable categories in the Herbicide Injury Photo database.  One is by the herbicide common or generic name, the other is by the crop or weed.  Both searches results in a plant pictured with injury from the named herbicide.

Pasture Weed Control Database contains the same information and pictures included in the Miscellaneous Publication MP-522. The weeds are arranged alphabetically by scientific name because common names vary. For example, in Arkansas, Eupatorium capillifolium, is variously called, Dogfennel, Cypress Weed, and Texas Cedar.

The Turfgrass Weed Control Database contains the same information and pictures included in the Miscellaneous Publication MP-521. The weeds are arranged alphabetically by scientific name because common names vary and thus be inaccurate.

There are nine searchable categories in the Weed Identification Database.  They are AQUATIC, GRASSES, LANDSCAPE, PASTURE, SEDGES, SPINY, and WOODY.  The idea is to help you narrow your search.  Weeds are not included in more than one category.  For example, horsenettle is a PASTURE weed but  it is found in the smaller category of SPINY plants.  Remember than plants do not always fit neatly into a single category.
