Due to a lack of post-emergence herbicides for use in sweetpotato, sweetpotato weed management is front-loaded with pre-emergence herbicides early in the growing season. For the last several years the following herbicide program has provided the most consistent control of the greatest diversity of weeds:
2 to 3 oz/acre Valor pre-transplanting followed by

The next few days will be abnormally frigid in North Mississippi. This increases the risk of chilling injury to sweetpotatoes in storage, and those being transported to or from packing sheds. Chilling injury occurs when roots are exposed to temperatures between 32 and 55°F. (The ideal storage temperature for sweetpotatoes is 55 to 60°F. Freezing injury . . . → Read More: Avoid Sweetpotato Chilling Injury

Maintaining clean and weed-free field roads around sweetpotatoes is thought to help minimize rodent injury and make access for crop scouting and monitoring more efficient. Roads are most often maintained weed-free with glyphosate applications. However, off-target movement of glyphosate onto adjacent sweetpotato plants can be problematic.
Sweetpotato vines exposed to glyphosate often exhibit chlorotic/yellow leaves and stems . . . → Read More: Glyphosate Injury to Sweetpotatoes Adjacent to Field Roads
It’s that time in the sweetpotato production season- where the last slips are making their way into the ground and herbicide treatments applied to the earlier planted crop get tested prior to canopy closure. While pigweeds and nutsedges represent the greatest threat to yield and quality, carpetweed (Mollugo verticillata L.) appears to be the on the . . . → Read More: Carpetweed- Unsightly but Not a Big Threat to Sweetpotato Fields
Every year at some point during the season we seem to hit a rainy spell where it seems to rain at some point every day and we have showers widely scattered across the state. It started raining last Wednesday and we have had some rain everyday since then and it is currently raining in Stoneville right now (Monday morning). With that, the questions start about how long you need to spray before a rain to get acceptable control. . . . → Read More: Influence of Rainfall on Insecticide Efficacy
