Insects & Diseases of Raspberries

Avoid insects and disease problems by good pruning, weed control and water management or consult the university Extension office in your area for a list of pesticides recommended for insect pests and disease control in raspberries. 

Watch for the following: 

Weak plants, chlorotic leaves indicates viral, fungal, bacterial, nutrient deficiency or herbicide injury.

Wilting indicates verticillium wilt, phytophthora rot, cane girdling by borers, spur blight, anthracnose, or winter injury.

Discolored leaves indicate orange rust, herbicide injury, or leaf yellow rust.

Bronzing indicates mite feeding.

Swollen crown indicates crown galls. There is no chemical control, and sanitation is recommended.
