Updated: February 10, 2023

Goji plants, also known as wolfberries, are a popular choice for gardeners who want to grow their own superfood. However, like any other plant, goji plants are susceptible to pests that can damage or even kill the plant. In this article, we’ll identify the most common goji plant pests and provide a treatment guide to help you keep your plants healthy.

Identifying Goji Plant Pests

Spider Mites

Spider mites are tiny insects that suck the sap from the leaves of goji plants. They are usually red or brown in color and can be difficult to spot with the naked eye. Look out for webbing on the leaves as this is a tell-tale sign of spider mites.

Aphids

Aphids are small, soft-bodied insects that feed on the sap of goji plants. They can be green, black, or brown in color and are often found on the undersides of leaves. If you notice distorted or yellowing leaves on your goji plant, it may be a sign of an aphid infestation.

Whiteflies

Whiteflies are small, white insects that feed on the sap of goji plants. They can be found on the undersides of leaves and can cause significant damage to the plant if left untreated. Look out for sticky honeydew on the leaves as this is a sign of whiteflies.

Fruit Flies

Fruit flies are a common pest that can infest ripe goji berries. They lay their eggs inside the berries, which can lead to spoilage and insect damage. If you notice small holes or larvae inside your goji berries, it may be a sign of fruit fly infestation.

Treating Goji Plant Pests

Natural Remedies

There are several natural remedies that you can use to treat goji plant pests. These include:

  • Neem oil: Neem oil is a natural insecticide that can be used to treat spider mites, aphids, and whiteflies. Mix 2 tablespoons of neem oil with 1 gallon of water and spray it on the affected plants.

Chemical Remedies

If natural remedies are not effective, you may need to use chemical pesticides to treat goji plant pests. However, it’s important to use these products carefully and according to the manufacturer’s instructions. Some common chemical pesticides that can be used to treat goji plant pests include:

  • Malathion: Malathion is a broad-spectrum insecticide that can be used to treat a wide range of pests, including spider mites, aphids, and whiteflies.
