glyphosate (  ) on burley tobacco (Nicotiana tabacum (burley type)) - 1440082


Host: burley tobacco (Nicotiana tabacum (burley type) L.)
Descriptor: Damage
Description: Glyphosate is a systematic herbicide that causes damage to tobacco within five to seven days after exposure. Injury first appears as a light yellow discoloration in the newly developing leaves. The leaf color changes from green to pale yellow and/or white from the base of the leaf to the tip. After exposure, newly formed leaves will be narrow and margins will be curled downward. Symptoms on mature leaves consist of areas of yellow or brown tissue between the veins while the remainder of the leaf looks normal. The yellow or brown interveinal area will frequently die and fall out leaving a shot- hole appearance. Higher exposure rates will cause death of the plant in seven to fourteen days after symptoms appear.
