In the south, with a few days of showers and clouds sheath blight has been on the move upward and reaching threshold levels in a couple fields. The fields scheduled for a fungicide treatment are Clark and Lonoke Counties. Arkansas County has sheath blight but not at the threshold level but watching closely. Stink bugs have increased to threshold levels but not in excessive amounts as some years. Those fields reaching treatment levels for stink bugs include Chicot, Desha and Lonoke Counties. Lee and Lincoln County are in the late boot stage. The Lincoln County hybrid field is scheduled for the late-boot nitrogen application.
In the north, the flood has remained at a good level in program fields. Sheath blight has remained low on the plants and suppressed enough by hot temperatures this week that no fungicide treatments have been needed to control the disease. Jackson has reached 50% heading and most program fields will be heading by next week. Sweeping for rice stink bugs will be routine for the next several weeks.
