Wild and neglected brambles should be destroyed within 600 to 1,000 feet of the planting. A good weed-control program should be used to eliminate host plants for the viruses. Soil should be tested for dagger nematodes, which vector viruses. Plants should be examined throughout the season for virus infection symptoms. If symptoms are detected, the plant must be removed. Strict aphid control should be maintained to prevent infection. These measures all are very important to the lifetime of a planting since the plant will remain infected for life once it is infected with a virus.
