South Arkansas: Fields range from 75% heading to hard dough stage. According to the DD-50, Lincoln and Prairie Counties are scheduled for draining next week. Lafayette and Jefferson Counties are scheduled to drain in 10 to 14 days. Prairie County has reached threshold stink bug numbers for the second time. Pulaski County has received a stink bug application while Clark County is waiting on an available airplane. The stink bug numbers in Lonoke County have declined as more rice was heading in the field. Disease pressure continues to remain low.
North Arkansas: Seven fields are either heading or headed with grain fill occurring rapidly. The eighth field, Randolph, reached mid-boot this week. This field has also reached the threshold for a sheath blight treatment which has been scheduled. Fortunately, the disease is still located relatively low on the plants. If that holds, the application will be delayed briefly and the rate increased so that it will also serve adequately as the first of two rice blast preventative treatments. Rice stink bug pressure has been well below treatment threshold in all fields this week.
