Agcenter sweet potato weed control grant

BATON ROUGE, La. (AP) - The LSU AgCenter has received a
three-year, $67,000 grant to study weed management options in commercial sweet potato production.
Weed scientist Donnie Miller and sweet potato specialist Tara Smith say they want to see which herbicides work best. They also want to see how the chemicals are affected by application timing and by spacing between plants and rows.
Miller says sweet potatoes are a relatively small crop, so manufacturers are less likely to put in the time and money needed to get their herbicides approved for them.
Plants that are planted closer together may produce smaller roots - but also can reduce weed growth by creating more shade between them earlier in the growing season.
