Frost & Spraying – Wait if Possible

Frost can interfere with herbicide performance and crop tolerance. After a light frost, it is important to wait until temperatures rebound in the middle of the day before spraying. After a heavier frost that caused damage (leaves are yellowed or necrotic), wait for plants to recover before spraying. New leaf growth should be visible on the crop to maximize crop safety and on the weeds to maximize control. Many herbicides have weather restrictions on their labels so check with local retailers or product providers for more recommendations. Always read and follow product labels.
