Both Roundup and Staple are effective in controlling a wide range of weed species often found in cotton. Staple Plus is a prepackaged mixture of Roundup and Staple. Staple Plus may be applied postemergence or postemergence-directed to RR cotton. Compared to weed control by Roundup alone, Staple Plus may be more effective controlling morningglories, dayflower species, and hemp sesbania. Additionally, residual weed control from Staple Plus may be noted on weeds such as pigweeds, spotted spurge, velvetleaf, and spurred anoda.
Residual activity is dependent on rainfall and herbicide contact with the soil.
Consult label for rotational restrictions to following crops. This product may also be applied using precision postemergence-directed or hooded sprayers to RR cotton through layby minimizing contact of spray with cotton. No more than two broadcast applications may be made from the first true leaf through the four leaf stage of development. No more than two postemergence-directed applications may be made from the fifth leaf stage through layby. All applications of this product must be at least 10 days apart and cotton must have at least two nodes of incremental growth between applications.
