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

Warm April weather in North Mississippi provides great growing conditions for sweetpotato plant beds. A few days near the 80s will have sweetpotato shoots pushing up the black plastic mulch that has been covering them since March. However, warm and humid conditions underneath plastic mulch can also provide an ideal environment for Southern blight, a disease . . . → Read More: Southern Blight and Sweetpotato Plant Beds

 Recently several groups in Mississippi came together and developed then adopted a set of Cooperative Standards for row crop farmers and beekeepers in an effort to increase awareness of pollinator’s and create an environment where each could coexist while minimizing any adverse conditions to either operation. As a part of that program the “Bee Aware” flag was . . . → Read More: “Bee Aware” Flags Ready for Distribution

Each year some sweetpotato scurf or “soil-stain†is reported. However, this year it would appear that the disease has been more prevalent than normal in some fields. Scurf is caused by a soil-dwelling fungus, Monilochaetes infuscans, and results in darkened, discolored skin (Figure 1). The affected portion of the root can range from a small patch . . . → Read More: Sweetpotatoes and Scurf

Last week’s harvest saw reports of “red potatoes†appearing in sweetpotato fields. There was speculation that the light-orange-skinned ‘Beauregard’ had altered its genetic make-up to the point that it had changed its skin color at multiple locations within the same field. While genetic mutations do occur in sweetpotato, there is a far more likely explanation. As . . . → Read More: “Why are there red potatoes in my field?â€

This week marked the first reported appearances of sugarcane beetles in sweetpotato fields in Mississippi for the 2013 growing season. The sugarcane beetle is a relatively new pest of sweetpotato in Mississippi. However, in recent years, heavy sugarcane beetle populations have caused significant losses for some growers in Louisiana, as roots with sugarcane beetle damage are . . . → Read More: Sugarcane Beetle Reported in Sweetpotato.

Yields for most Mississippi sweetpotato growers are anticipated to be on par with expectations. However, growers not content with their yields should take a critical look at the vines that ride up the front of the digger- each one tells a story. Here are three non-pest related contributors to insufficient yield:
