  • Unexpected herbicide damage: Scenarios

    Sprayer performance tips

    Unexpected carryover can occur when dry conditions in the year of application slow the expected pace of breakdown of herbicides. Unexpected residue damage is a risk any time a sprayer is left full while waiting for an opportunity to spray, or when sprayers are not effectively cleaned between crops and between products.

If wind or rain delays spraying, the concentration of scrubbed-free herbicide residue in the tank can continue to increase.
