South Arkansas: All fields have gone to flood except the Pulaski County field. The levees were pulled and 2.6 inches of rain fell before the gates could be installed. According to the DD-50 we have reached the final time to apply pre-flood N and will start spoon feeding. Most all fields are growing well with Prairie, Lincoln and Lafayette Counties approaching ½ inch internode elongation. Rice water weevils (RWW) have been very active in the Clark, Lonoke and Desha County fields. RWW recommendation has been made for Clark County yet plane availability has the application on hold. Lonoke and Desha Counties received insecticide seed treatments yet scarring is significant and could reach threshold levels this coming week. The Jefferson County row-water field has received its 3rd application of nitrogen .
North Arkansas: All fields are progressing well. Poinsett and Jackson went to permanent flood this week which brings the total number of fields with the permanent flood applied to seven. That leaves only Randolph which now has a field of young rice in the program. Rice water weevil scaring has been observed in every field within the first week of flood-up but fortunately, the infestation has been well below treatment level in each case.
