South Arkansas: The southern fields are progressing rapidly with ample heat units accumulating fast. Disease pressure has been very low with sheath blight at a minimum as of now. The Jefferson and Lincoln Co. row water fields are scheduled for late boot N applications starting next week. The Jefferson Co. field should be at 50% heading on 7/9 according to the DD50. The Desha Co. field has received midseason N and the Monroe Co. field has it on the books to go out. Several fields are in the reproductive stage and are struggling to maintain a proper flood in areas of some paddies. During scouting, dry to moist soil has been detected and in most cases has been easily corrected. As the boots are filling stink bugs are building and waiting on rice to head.
North Arkansas: All fields in the program continue to progress well. The disease pressure is very light thus far. Sheath blight detected in Jackson Co. has remained low on the plant with positive stops well below treatment threshold for another week. One disturbing phenomenon however is all the rice stink bugs that are already so easily visible in virtually every field. According to the DD50, there will not be seed heads emerging and susceptible to stinkbug damage in a program field for another week. We will continue to keep a close watch on the situation and start routine sweeps for the stinkbugs in each field at 75% panicle emergence.
