Q.insect pest
I have a large prostrate pine that has died. The bark flaked off and there are ‘bug trails’ in the surface of the wood. Will this spread to other pines? What is the time frame for killing these bugs and what will work?
Correctly identifying the disease or insects is key to any possible treatments.
Here are some links that may help pinpoint the cause.
Consulting a certified Arborist to help make the correct diagnosis may be the best solution, especially if more trees may be involved.
Contact your local County Extension Office, they are a valuable source of information on the local management of diseases.
