One of the major objectives of the cotton grower is to produce high quality cotton that meets or exceeds the expectations of the consumer, while making a reasonable profit. One important aspect of high quality cotton production is in-season weed control. Traditionally, cotton growers have turned to mechanical cultivation, and more recently, to selective postemergent herbicides for this weed control. However, a new alternative exists that provides excellent weed control while offering many other benefits ... chemical cultivation using a shielded sprayer and Roundup herbicide.
