LIVING with cherry DISEASES

摘要

With no cure for cherry trees infected with most viruses—short of cutting them out of the orchard—Washington State University researchers are focused on developing effective management strategies for growers to use in controlling the spread of viruses. Dr. Ken Eastwell, Washington State University plant virologist and director of the Clean Plant Center of the Northwest that's based in Prosser, Washington, has worked with the Pacific Northwest cherry industry for many years to help growers deal withviruses and diseases that cause economic loss through decline in tree health, fruit quality and yield. Cherry leaf roll virus, little cherry disease, and western X are among the diseases of late that have posed problems for Northwest growers.
