PHIs and Herbicides Peanut Notes No. 150 2019
We are approaching the PHI (pre-harvest interval) for some of the herbicides we use in peanuts. The selective grass herbicides will have no negative impact on peanuts sprayed at this time of year. 2,4-DB will also have no negative impact on peanuts. Cobra, Ultra Blazer, and Storm can negatively impact yield under some conditions when applied this late in the season. The PHI for Cadre has passed.
