Disease of the Goji Berry Plant


The goji berry plant (Lycium barbarum) is an ornamental, fruit-bearing plant traditionally grown in China. The plant has become popular in recent years for its purplish-red berries touted as an ideal superfood. The plant is now grown in many countries and has even been adapted as a backyard garden plant in the United States.


The goji plant is a target for pests and diseases. Many insects and animals enjoy snacking on the tender leaves. The plants are also susceptible to potato blight and fungus disease resulting from too much moisture.


Since the early 21st century, high levels of insecticide and fungicide residues have been detected by the USDA in goji plants and products imported from China. UK officials attempted to recall some 86,000 infected plants from their garden centers and nurseries.


Goji plants belong to the solanaceous or "night shade" family. This affiliation gives them the potential to pass on any developed diseases to such crops as tomatoes, potatoes and peppers.

Time Frame

Because goji plants are winter hardy, they can be the source of infection for many years. Tomato worms, in particular, can transfer diseases from the goji to other plants in the area, which could result in a long-term disease epidemic.


Fungal disease in the goji plant can be prevented by keeping the leaves as dry as possible. Plants should be watered in the early morning and also from the bottom.
