Young trees can show injury after glyphosate application the previous year. One symptom of glyphosate damage is small spindly leaves that look like zinc deficiency. Shoot tips die so you get clustered growth.
- Micronutrient (and often some macronutrient) deficiency
- Low vigor, slow growth, stunting
- Leaf chlorosis (yellowing), complete or between the veins
- Leaf mottling with or without necrotic spots
- Leaf distortion—small, curling, straplike, wrinkling, or “mouse ear”
- Abnormal bud break, stem proliferation, witches’ broom
- Retarded, slow regrowth after cutting or running (alfalfa, perennial plants)
- Lower yields and lower mineral value in vegetative and reproductive parts (grains, seeds)
- Early fruit, bud, or leaf drop
- Early maturity, death before physiological maturity, tip dieback
- Predisposition to infectious diseases and extended infection/susceptible period
- Predisposition to insect damage
- Induced abiotic diseases—drought, winter kill, sun scald, bark cracking (perennial plants)
- Root stunting, inefficient nitrogen fixation and uptake
- Poor root nodulation in legumes
