Auxin Residues and Peanuts Peanut Notes No. 24 2018
Peanut seed is the single most expensive input in peanuts and everything should be done to avoid stand loss. Product labels can be vague and often mention “until residue has dissipated.” When rainfall occurs after application of auxin herbicide and planting is 4 weeks out there should be no major issue. Research has shown that applications closer to planting can be okay if rain occurs, but it is risky.
