Add additional mulch only to maintain a 3 to 4 inch depth. Inspect the depth of the mulch layer each year.
Remove the bottom most branches from the trunk to help increase air circulation around the tree. Use the mature size of the tree as a spacing guide when planting. This disease thrives under warm, wet conditions.ĭon’t overcrowd plants. Spots and bands caused by brown spot needle blight Maintain good air circulation around trees The following pines may develop low levels of brown needle spot, but are rarely significantly damaged by the disease. In the great lakes region, this disease causes significant damage to:Īll pine species in Minnesota can be infected with brown spot needle blight to some extent. Trees affected by brown spot needle blight in Minnesota Submit a sample to the Plant Disease Clinic for testing. Lab analysis is often necessary to distinguish brown spot from Dothistroma needle blight. Infections are most common on lower branches and young trees.ĭisease is most severe during long, warm, wet summer weather. In autumn, diseased needles turn reddish-brown and fall off leaving bare areas on the limb. These small, pimple-like structures produce fungal spores. Within the spots, you may see tiny black bumps pushing through the surface of the needle. The base of needle remains green with random yellow-to-brown spots in the center of the needle. Small, yellow-to-brown, resin-soaked spots form on needles throughout the summer. Recently, the species has been afflicted by the fungal disease known as red band needle blight, causing a major decline in the species in the United Kingdom.Young pine infected with brown spot needle blight
