Combatting Common Tree Diseases in Salt Lake County

Coryneum Blight

Coryneum blight creates small circular leaf spots that drop out and form holes. This fungal infection attacks fruit and ornamental trees. It loves cool, wet springs. Utah’s weather creates perfect conditions for this disease.

Symptoms

Look for tiny brown spots on leaves. The spots have dark rings. Centers drop out. Leaves look like someone shot holes through them. Blossoms and fruit get spots too. Infected branches may die back.

How to Combat

Remove infected leaves and branches immediately. Don’t leave them on the ground. Rake up fallen leaves in fall. Apply fungicide in late fall. Reduce leaf wetting by watering at soil level. Plant resistant varieties when possible.

Anthracnose

Anthracnose causes dying terminal foliage, bud damage, and premature leaf drop. This fungal disease spreads fast during wet springs. Maples, sycamores, and oaks suffer most. Leaf browning and twig dieback signal infection.

Symptoms

New shoots look blackened. Buds fail to open. Leaves develop brown patches. Witches’ broom growth appears (twisted, dense branch clusters). Leaves drop early. Trees look thin and weak.

How to Combat

Clean fallen leaves every fall. Prune infected limbs below the damage. Apply fungicide in early spring. Use systemic treatments on valuable trees. Water deeply during dry periods. Improve air circulation through proper pruning.

Powdery Mildew

Powdery mildew appears as white or gray powdery patches on leaves and shoots. This fungal infection weakens trees. Apple trees suffer most in Utah. Warm days and cool nights create ideal conditions.

Symptoms

White powder covers leaves. Shoots look dusty. Leaves curl and distort. Growth slows down. Buds lose viability. Trees look unhealthy overall.

How to Combat

Prune branches to improve sunlight. Increase air circulation around the canopy. Remove crowded growth. Water at the soil level. Avoid overhead watering. Apply sulfur or neem oil if needed.

Fire Blight

Fire blight blackens blossoms, shoots, and branches and spreads rapidly. This bacterial disease kills apples and pears. It moves fast in spring. One infected branch can spread to the whole tree.

Symptoms

Blossoms turn black. Shoots wilt suddenly. Branches look burned. Cankers form on limbs. Oozing appears on bark. Trees decline quickly.

How to Combat

Prune well below infected tissue. Disinfect tools between every cut. Remove infected branches in dormant season. Apply copper treatments in winter. Consider tree injections for severe cases. Sterilize pruning equipment with bleach.

General Disease Prevention and Management

Proper Watering

Proper watering prevents stress-related disease vulnerability during dry periods. Water deeply at the soil level. Water early morning. Avoid evening watering. Stressed trees catch diseases easier.

Mulching

Organic mulch helps retain moisture and protect roots. Use 2-4 inches of mulch. Keep mulch away from the trunk. Never let mulch touch bark. Good mulch prevents root problems.

Pruning

Routine pruning removes dead, diseased, or crossing branches. Pruning boosts airflow. It increases sunlight penetration. Remove dead wood first. Cut crossing branches. Thin dense areas.

Sanitation

Sanitation removes fallen leaves and fruit that carry disease. Rake leaves in fall. Remove dead branches. Clean up fruit. Dispose of diseased material properly. Don’t compost diseased leaves.

Soil Health

Balanced soil fertility supports strong tree immunity. Test your soil. Add nutrients if needed. Avoid over-fertilizing. Healthy soil means healthy trees.

Professional Help
