How to Manage Pests
Pests in Gardens and Landscapes
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.
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.
