In the south, the rains and clouds have moved out and have put the brakes on sheath blight movement. Stink bugs have dispersed and numbers have remained below threshold levels this week. There have been no fungicide or insecticide applications needed this past week. Cooler temperatures have been welcome with the flowering rice. The Chicot Co. field should be the first harvested. Drain date is 7/28 and 20% harvest moisture date is 8/7 according to the DD-50.
In the north, six of the eight program fields are pollinating heavily this week and the seventh will reach that stage sometime next week so timing of the cooler temperatures is excellent for all those fields. All fields are well watered and none have required an insecticide treatment at this point. The only fungicide treatment in this update is one inadvertently left out of the update last week for Poinsett Co. where a treatment for kernel smut suppression was applied prior to boot split. No fungicide treatments needed this week.
