Signs of damage
There are different patterns of damage according to different herbicides but also according to the affected plants:
- Leaf damage. Leaves can display various signs, from curling and cupped leaves to chlorosis that makes leaves discolored and dead spots. Leaves can also have their texture altered and develop into abnormal shapes.
- Flattened stems.
- Corkscrew and twisting stems.
- Necrosis.
- Stunted growth.
How to prevent
Reducing other stress factors will make the plant less susceptible to a higher degree of damage and increase the chances of recovery. This, paired with optimal growing conditions and care, will contribute to plant resistance and overall vigor. These practices include watering during droughts, adequate fertilization, and controlling other pathogens and diseases.
If you’re using herbicides for weed control, always follow the instructions, and leave some safety distance between the plants that shouldn’t be exposed, such as ornamental or crops. Avoid applying it on windy days, hot days, or hot hours of the day, since temperature increases chemical toxicity.
Heal
The degree of damage will determine the likelihood of recovery. It also depends on the herbicide used since soil sterilants are the hardest for plants to recover from. The good news is if the plant doesn’t lose its vigor and has new growth, it is more likely to recover.
