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.
