A small amount of MH exposure in a transplant can cause dramatic strapping of leaves.
A small amount of residue left in a spray tank can cause severe damage to plants in the field.
Over-application of MH can also cause leaf damage.
A reduced rate of MH (1.5 gal/A) in combination with Prime+ or Butralin reduces the risk of field damage and improves sucker control.
