How to Manage Pests

Pests in Gardens and Landscapes

Virus diseases

Several virus diseases may affect caneberries such as tomato ringspot, raspberry mosaic, tobacco streak, calico, and bushy dwarf virus. Virus diseases cause caneberries to develop weak, spindly canes. Leaves may cup downward and redden or yellow prematurely in the fall. Plants become unproductive in 2 to 3 years.

Solutions

Virus diseases may be transmitted by pollen, insects and nematodes when they feed on an infected plant and then a healthy one, or even virus-infected plant material. There is no cure. Remove infected plants immediately. Obtain virus-free plants from a nursery. Insecticides applied to control insects are not effective.
