Pine beetle infestation

Can you recognize this?
This is a textbook case of Blue Fungus caused by a pine beetle infestation. It is also called blue strain and is very common in some conifers...and it is very harmful.

Here are some things you can do to help your infestation.
Plant more resistant species such as longleaf pine and slash pine in place of loblolly pine and planting loblolly pine only on appropriate sites (i.e., right tree for the right place);

Thin overstocked, dense or stagnant stands to a basal area of 80 sq. ft. per ac. (18 sq. m per ha) or less;

Maintain at least 25 ft. (8 m) distance between mature pines in urban settings;

Promote tree diversity in the landscape;

Remove damaged pines;

Maintain tree health and vigor by supplemental watering during extended dry periods;

Minimize construction and logging damage to pines and avoid soil compaction during operations;

Minimize changes in soil and water levels around pines;

Conduct logging or land clearing operations during coolest winter months;
Shorten rotation ages to less than 30 years; and

Apply an approved insecticide to high-value trees when the threat of SPB attack is imminent and the potential benefits outweigh the costs and risks of chemical use.
