Preplant Burndown Time in NC
Much of North Carolina cotton is grown in no-till or strip-till systems. That means they require a preplant burndown treatment to control winter weeds and/or cover crops.
Guy Collins, NC State Extension cotton specialist, reminds growers that mid-March through the first week in April is generally the ideal time for burndown applications. In a recent post on the NC State cotton webpage, Collins provides a visual guide to problem weeds in the state, as well as several burndown recommendations for cotton fields.
