Phenoxy Injury
List of files and visuals associated with this text.
(E.g. 2,4-D, 2,4-DB)
Phenoxy injury is characterized by twisted stems and leaf
petioles, callused stems and malformed leaves that appear
strapped and puckered or crinkled. (Vis. 1) Injury from
2,4-DB may cause stems to become brittle, split and show
adventitious roots. A plug may form at the base of the
plant, thereby weakening the stem. Applications of 2,4-D
ahead of soybean planting may reduce stands, inhibit
emergence and cause injury to the existing stand. Sever
phenoxy injury will result in yield reduction,
particularly when injury occurs during flowering, pod set
or pod fill. Injury at this time will result in reduced
pod set and development, and plants will remain green
until frost.
