South Arkansas: With hot weather and heat units hopefully here to stay the rice is progressing fast. Arkansas and Lincoln Counties are at green ring to joint movement stage. Ashley County has had the levees put in and is now being flooded. Phillips County is waiting on the levees so we can apply herbicides then fertilize and flood. ALS resistant annual
sedge is more prevalent in South Arkansas than ever. The Monroe County field has a 2 acre spot that has walked through a Permit Plus application. The field will have to be spot treated with a Basagran and Propanil tank mix to get it under control.
North Arkansas: White and Lawrence Counties are the sixth and seventh counties respectively to receive their N-STaR nitrogen application and permanent flood. Both fields received a post-emergence herbicide application before flood-up. River flood water finally drained off the Randolph County field over the weekend. Its evaluation will continue throughout this week. All other fields are progressing normally with canopies beginning to close as we move into sheath blight season. DD-50 is spot-on now for most fields. Cross and Jackson Counties are scheduled for their mid-season urea this week.
