If you are in the quarantined area of Adams County, you should contact the PDA, Bureau of Plant Industry or the Penn State Cooperative Extension of Adams County. There are no simple and easy control methods at the present time. That is why you have to remove the plants and get the disease out of the area before it spreads to more plants. The disease does not kill the plants. It causes tree production to decrease considerably, causing major production losses for orchard operations.
Some varieties have symptoms on the fruit, making it undesirable or unmarketable for packers.
Having the virus present in the area will make it extremely difficult for fruit tree nurseries to sell their nursery stock. Economically speaking, all of this would make peaches harder to grow and make a profit. This is not an easy question. First, we don't even have enough information to answer a question like this. Second, more leaf samples are going to be needed next spring to see if the virus is in other areas of the county.
