Can an SU be tank mixed with AXIAL + ADIGOR?
Yes, as long as the AXIAL is applied at the full dose rate for the target weed, i.e., wild oats – 0.3 l/ha, ryegrass – 0.45 l/ha, and weeds are actively growing. If applying separately and AXIAL is applied first, then 7 days must elapse before an SU can be applied, but if an SU is applied first, then 21 days must elapse before AXIAL can be applied.
Has the MAPP No for CALLISTO changed, only the new one doesn’t have the EAMU for linseed?
