A field was prepared and bedded with Prowl incorporated and received good rain activation, but prior to being able to plant peanut, other delays resulted in yellow nutsedge/nutgrass emerging with some small pigweed. Dr. Marshall's recommendation was that if there is flexibility to wait 3 to 5 days after spraying a burndown before planting, an application of roundup + MSO would be more effective than an application of paraquat, but the roundup needs those few days to absorb and work, after which we can follow the planter with normal Valor and Dual, and then an at-crack paraquat, with later Cadre plus dual if rotation concerns are not a concern. If time was limited and there is a need to plant sooner without waiting 3 to 5 days for a roundup application, the next best option would be paraquat 3 pt plus NIS as a burn down, then follow planter with preemerge valor/dual, etc.

Chlorpyrifos is the active ingredient in insecticides such as Lorsban 15G and Chlorpyrifos 15G. Several years ago, prior to its being banned (court ruling history), it was considered to have offered the greatest control to insect pests such as lesser cornstalk borer, southern corn rootworm, and burrower bug. Notices by the EPA have detailed final cancellation orders for registrations of pesticides containing chlorpyrifos (including notice and notice). These notices also provide provisions for the sale, distribution, and use of existing stocks of specific products containing chlorpyrifos until June 30, 2025, provided such use is consistent with the product label. Liquid formulations of chlorpyrifos (e.g., Chlorpyrifos 4E) are not recommended for use in an established peanut crop due to their decreased application to the target site in the soil and their potential to cause burn on peanut leaves. It is noted that the label for Drexel's Chlorpyrifos 15G does not contain burrower bug. In addition to confirming product labels for intended usage, it is important to confirm if a peanut contract excludes use of this active ingredient. Peanut burrower bug damage is sporadic, but it has been observed in a few cases in SC in recent years. When present, it can cause loads to be designated Seg II. Management options overall are quite limited for peanut burrower bug, and insecticide active ingredients other than chlorpyrifos have so far not been encouraging. Irrigation can provide some help. Deep tillage can also provide some help, but use of this for various reasons has declined, and many fields are finished with tillage operations. From some of Dr. Abney's work, Georgia 06G appears to be more susceptible to burrower bug. The attached images compare differences between peanut burrower bug (a pest) and white-margined burrower bug (not a pest).
