Photograph of a close-up shot of a partially killed bindweed plant area in a wheat field sprayed with 2-4-5T in the spring of 1956. The back of the photograph proclaims, "Close-up of bindweed area in wheat field sprayed with 2-4-5T in the spring of 1956 received only partial kill. This weed is a very rapid spreader and will cover large areas in a short time if it is not controlled. It is resistant to poisons and needs constant tillage. It will kill out other vegetation as it increases."

Photograph of a close-up shot of a bindweed plant area at the edge of a wheat field. The back of the photograph proclaims, "Close-up 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 receives enough moisture to encourage growth. If not controlled it will spread rapidly into the adjoining wheat field and cause much damage to the wheat. It is resistant to poisons and needs constant tillage. It will kill out other vegetation as it increases."

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.

Photograph of Bindweed. Close up 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 receives enough moisture to encourage growth. If not controlled it will spread rapidly into the adjoining 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. OK-354-2.

Photograph of a close-up of stubble mulch tillage on the contour with impounding type terraces. The wheat stubble was left on the ground to control wind erosion, increase water intake of the soil and to add organic matter to the surface of the soil.
