Abstract

In semi-arid areas, good control of field bindweed with 1 lb/A of 2,4–dichlorophenoxyacetic acid (2,4–D) will occur if there is at least 1.5 inches of available soil moisture when runners are 6 to 10 inches long. Under these conditions carbohydrates are high in the leaves and low in the roots. Analysis of rainfall records from Amarillo, Texas indicates that soil moisture conditions during May will be favorable for good bindweed control with 2,4–D 54% of the time.
