Rice Research Verification Program Update – June 15, 2018
Author: Ron Baker, Rice Research Verification Program Coordinator

By Ralph Mazzanti and Ron Baker, Rice Research Verification Program Coordinators

In the south, water supply and flood depth have become critical in even more counties this week. The struggle for water now includes Jefferson, Clark, Desha and Lincoln Counties. Loyant herbicide is struggling to maintain control of barnyardgrass in Lincoln and Desha Counties. This is due to the inability to maintain proper flood depth. Chicot and Desha Counties are in the reproductive stage of ½” internode elongation (IE) and beyond, and water consumption is at the maximum rate. So far, preflood nitrogen loss has been minimal using GreenSeeker technology. Hydrogen sulfide toxicity is being monitored in fields with proper flood depth with some symptoms observed in the Arkansas Co. field.

In the north, scattered showers have helped considerably and program fields are not experiencing difficulty holding an adequate flood at this time. Woodruff will receive its permanent flood over the weekend and is the last to do so. The other program fields are all progressing really well with several at green ring or beyond. Weed control remains good to excellent at this point for all but Woodruff where only time will tell if the large patches of barnyardgrass will be sufficiently controlled by the sequential Newpath treatment applied this week.
