Dan Anco Clemson Comments Peanut Notes No. 74 2026

(Updated: May 12, 2026, 10:13 a.m.)
Peanut field being planted in spring.

In-furrow Vertento label approvedThe FIFRA 24(c) Special Local Need Label for Vertento (isocycloseram) has been approved for the state of SC (attached) to allow in-furrow use of this product for rootworm species (southern corn rootworm & banded cucumber beetle). Data from Mark Abney with UGA has shown this product to be effective. This is particularly helpful for fields where rootworm injury has been observed due both to the user-friendly nature of in-furrow application and the lack of other available effective options for this pest.

The attached pictures show thrips injury on Valencia peanut, Valor/flumioxazin injury on seedlings that should recover without impacting yield, and a stand that is slow to emerge following being planted three weeks ago into dry soil. The first week after planting was also dry, with approx. 1.6" rain being received during the second week after planting. The seed are starting to come up. (the images are not attached to this post)
