Question:
I have several Afghan pine trees in a windbreak around my property.The needles will start to turn yellow and die in turn the complete branch will eventually die. The needles develop yellow ends with a black spot about 1/2 in from tip eventually causing the entire branch to die. We live in zone 7 in Texas We have treated with fungicide Dacinol this spring, repeatedly with no results. What is the possible cause and remedy?

Replies:
There are several diseases, insects, and nematodes that affect pine trees. The following might help. Also check with your local agricultural extension office.
