Photograph of bindweed control. A close-up of bindweed area in a wheat field sprayed with 2,4,5-T herbicide in the spring of 1956 only partially killed. This weed spreads very rapidly and can cover large areas in a short amount of time if not controlled. It is resistant to poisons and needs constant tillage. It will kill out other vegetation as it increases. OK-353-12.

Photograph of bindweed area at the edge of a wheat field. This area is uncontrolled and is in excellent condition. It is in a low spot where it received enough moisture to encourage growth. If not contolled it will spread rapidly into the ajoining wheat field and cause much damage to the wheat. It is resistant to poisons and can be controlled only by constant tillage. It will kill out other vegetation as it increases.
