Cotton Tolerance and Weed Management with Sharpen

Studies were conducted in 2009 to determine cotton tolerance to pre-plant burndown applications of four rates of Sharpen.  Results showed injury to cotton with higher rates of Sharpen and no injury with lower rates.  Sharpen was also tested for efficacy on Texas blueweed, woollyleaf bursage, kochia, field bindweed, ivyleaf morningglory and volunteer Roundup Ready cotton.
