South Arkansas: Prairie County, the earliest planted field is at soft to mid dough stage. Lincoln and Lafayette are at milk to soft dough stage. Those fields ranging from 50-75% heading are Clark, Desha and Jefferson. Lonoke and Pulaski range from 30-50% heading while Arkansas is at boot split. Rice blast preventative treatments and stink bug applications have been made this past week. The Desha and Clark County fields both received fungicide and insecticide treatments. Lincoln and Prairie were treated for stink bugs last week while Prairie was treated the week before. The positive stops for sheath blight remain low and are not at threshold levels.
North Arkansas: Four program fields are now in various stages of heading and the others are not far behind. Two fields, Conway and White Counties, reached treatment level for rice stink bugs this week. In addition, preventative treatments for rice blast and kernel smut were applied in St. Francis County, a kernel smut preventative application was made in Poinsett County and a treatment for sheath blight and kernel smut was made in Jackson County.
