How do you get rid of fungus on pine trees?

Do not plant young, healthy two- and three-needled pines near older, infected pines. Remove infected twigs to reduce the amount of fungus in the tree. Apply a fungicide beginning as the buds swell in the spring and repeat application until the needles reach full size. Spraying at other times is not effective.

Brown spot can be controlled by fungicidal sprays. The first application should be applied when the new needles are about half-grown (May-June), and a second spray three to four weeks later.

What kind of fungus is on white pine trees?

White pines develop swollen cankers on the trunk or branches. Resin flows from the cankers. Powdery, yellow to cream-colored spores erupt from the cankers in May through July, two to three seasons after infection. Branches and entire trees are girdled and die. Spores formed on the pine infect the leaves of currants and gooseberries (Ribes).
