herbicides (general)

Host: flue-cured tobacco (Nicotiana tabacum (flue-cured type) L.)
Descriptor: Damage
Description: Injury symptoms from dicamba and picloram are identical but tobacco is much more sensitive to pircloram. Symptoms are somewhat similar to 2,4-D. Young leaves are often strapped, while the edges and tips of the leaves curl downward, giving a "parrot-beak" or "cobra-head" appearance. A small pointed tip usually protrudes from the end of the leaf. Leaf margins are not serrated as is common with 2,4-D. Severe injury is characterized by strapped and stubby young leaves. Bud leaves are often short and stubby with rounded tips.
