Common Blackberry Plant Pests:
Prevention and Control Methods

Blackberries are a popular fruit among gardeners, but they are often plagued by pests that can damage the plant and reduce its yield. In this article, we will take a look at some of the most common blackberry plant pests and provide tips on how to prevent and control them.

Spider Mites

Spider mites are tiny arachnids that can cause significant damage to blackberry plants. They feed on the plant’s sap, which can lead to yellowing leaves, stunted growth, and reduced yield. Spider mites thrive in hot, dry conditions and can quickly multiply if left unchecked.

Prevention

To prevent spider mites, it’s essential to keep your blackberry plants well-watered and cool. You can also introduce predatory insects, such as ladybugs and lacewings, into your garden to help control the spider mite population.

Control

If you notice spider mites on your blackberry plants, you can try spraying them with a mixture of water and dish soap or neem oil. Alternatively, you can use an insecticidal soap or miticide designed explicitly for spider mites.

Japanese Beetles

Japanese beetles are a common pest that can cause extensive damage to blackberry plants. These shiny green beetles feed on the plant’s leaves and berries, leaving behind skeletonized foliage and damaged fruit.

Prevention

To prevent Japanese beetles, you can try using natural deterrents such as garlic or onion spray. Another effective method is to use pheromone traps to lure the beetles away from your blackberry plants.

Control

If you have a severe Japanese beetle infestation, you may need to resort to chemical insecticides. Be sure to read the product label carefully and follow all instructions for safe and effective use.

Raspberry Fruitworms

Raspberry fruitworms are small beetles that lay their eggs on blackberry plants. The larvae feed on the fruit of the plant, causing it to become misshapen and stunted.

Prevention

To prevent raspberry fruitworms, it’s essential to keep your garden clean and free of fallen fruit. You can also use row covers to prevent adult beetles from laying their eggs on your blackberry plants.

Control

If you notice raspberry fruitworms on your blackberry plants, you can try handpicking the affected fruit and disposing of it. Alternatively, you can use insecticides designed specifically for fruitworm control.
