Rice Research Verification Program Update for June 4, 2018
Author: Ron Baker, Rice Research Verification Program Coordinator

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

In the south, the fields with permanent flood are Arkansas, Chicot, Desha, and Lonoke Counties.

Lee, Jefferson, and Clark Counties are scheduled for herbicide applications then fertilizer followed by permanent flood. The Lincoln Co. (continuous rice) field has multiple resistant weed species prevalent. The wind along with adjacent soybeans has limited herbicide choices.

In the north, scattered showers, high winds and adjacent susceptible crops have made it difficult to apply scheduled post-emergence herbicides and preflood nitrogen. This has made it necessary in some cases to apply only grass herbicides for now and schedule broadleaf herbicides as more favorable wind conditions allow. The objectives of that strategy are timely, essential grass control plus application of the preflood N and permanent flood within the optimal DD-50 window.
