herbicides (general)

Host: burley tobacco (Nicotiana tabacum (burley type) L.)
Descriptor: Damage
Description: Phenoxy herbicides such as 2,4-D, dicamba, and MCPA on tobacco cause symptoms which vary with the herbicide rate and the age of the affected plants. Young leaves become stiff, puckered, elongated, and often have serrated edges. Midribs of affected leaves are prominent and may extend as a pointed needle-like projection or tail at the end of the leaf. Higher dosages cause the leaves to be "strappy" in appearance. High rates may also cause extensive twisting of stalks and leaf petioles. On older plants, leaf margins will curl downward, and the midrib will bend downward.
