Sycamore trees are primarily affected by fungal infections and bacterial issues that impact their leaves, twigs, and bark. While some conditions cause premature leaf drop, proper tree care, sanitation, and watering usually allow the tree to recover on its own.1. Sycamore AnthracnoseThis is the most common and serious disease affecting sycamores. It is a fungal pathogen (Apiognomonia spp.) that thrives in the cool, wet weather of spring.Symptoms: Small, unfolding leaves turn brown and wilt, while mature leaves develop dead areas along the veins. It can also kill shoot tips (dieback), forcing the tree to grow multiple twigs from one spot (known as "witch's broom").Management: The tree will generally recover and push out a new set of leaves when the weather turns warm and dry. Rake and destroy fallen leaves and twigs to prevent the fungus from overwintering.2. Powdery MildewA fungal infection that appears later in the growing season, typically in late summer or autumn.Symptoms: A heavy, white, powdery coating develops on the upper surfaces of the leaves, often causing them to curl or distort.Management: It rarely causes serious damage to mature trees, so treatment is generally not recommended unless the tree is very young or high-value.3. Bacterial Leaf ScorchThis is a systemic bacterial infection that interrupts the tree's water-conducting tissues.Symptoms: Scorched or brown patterns appear along the margins of the leaves between the veins, typically showing up mid-to-late summer.Management: Keep the tree adequately watered and fertilized to reduce stress. In some cases, professional arborists can use antibiotic root flare injections to suppress symptoms.4. Canker StainA highly destructive and often fatal fungal disease that attacks the vascular system of the tree.Symptoms: Dark, elongated cankers form on the trunk and branches, often exuding sap. The leaves above the cankers will wilt and turn brown.Management: This disease is highly contagious and spreads primarily through pruning tools or beetles. It is crucial to disinfest all tools with rubbing alcohol or bleach immediately after use to prevent spreading.Best Prevention PracticesKeep Trees Healthy: Ensure the tree is properly watered during dry spells and mulched appropriately to reduce environmental stress.Sanitation: Clear away and dispose of infected leaves and fallen debris around the base of the tree.Consult Professionals: If your tree is suffering from severe dieback or suspect Canker Stain, consult an ISA Certified Arborist for localized diagnosis and potential trunk

Completed two jobs today. Visited Oktaha to trim an elm tree away from a house. Then, proceeded to Muskogee to remove a maple tree.

Dutch elm disease (DED) is a highly destructive, lethal fungal disease that attacks elm trees. Caused by invasive fungi (most notably Ophiostoma novo-ulmi), it triggers a defensive response in the tree that blocks its water-transporting vessels, resulting in rapid wilting, crown dieback, and eventual tree death.How the Disease SpreadsBark Beetles: The primary vectors are elm bark beetles. The beetles carry fungal spores and introduce them into the tree's vascular system while feeding on young twigs.Root Grafting: The fungus can travel underground through interconnected roots (root grafts) from an infected tree to a healthy, neighboring elm.Pruning Tools: It can also be spread by using contaminated pruning equipment on healthy trees.Common SymptomsLeaves on one or more outer branches begin to turn yellow, curl, wilt, and turn brown (often starting in late spring or summer).The wilting and dieback progress rapidly down the infected branch towards the trunk.Peeling back the bark on an infected branch often reveals dark brown streaks or rings in the sapwood.Prevention & TreatmentNo Cure: Once a mature tree is heavily infected, there is no known cure.Preventative Injections: Licensed arborists can use systemic fungicide injections to protect highly valued, uninfected elms from the disease.Pruning and Removal: If caught in the very early stages, infected branches can be heavily pruned to save the tree. Severely diseased trees must be removed and properly disposed of to prevent beetles from using the wood as a breeding ground.Resistant Varieties: Researchers have developed DED-resistant elm cultivars and hybrids that are less vulnerable to the pathogen.To learn more about identifying or protecting elm trees in your area, consult the USDA Forest Service overview or your local state extension service.

Recently, invasive emerald ash borers were found near Tulsa. Here’s what you need to know. ⤵

The emerald ash borer, an invasive beetle, has been confirmed in Broken Arrow, which means our community’s ash trees are now at risk. These insects can fly up to 15 miles a year and often spread farther by hitching a ride in firewood, shipping materials, or logging equipment.

Once they reach a tree, emerald ash borers lay eggs on the bark. When the larvae hatch, they burrow into the tree and feed on the phloem and cambium layer under the bark, which is the part that carries water and nutrients. This damage eventually kills the tree, often quickly, and dead ash trees become brittle and hazardous.

🪲 How to spot an infested ash tree:
• Tiny D shaped holes in the bark, where adult beetles exit.
• Canopy thinning or dead branches.
• Increased woodpecker activity may indicate larvae under the bark.

🌳 What you can do if you have ash trees on your property:
• Contact an ISA certified arborist or Oklahoma Forestry Services to confirm whether your tree is affected and discuss treatment options.
• Avoid moving firewood or untreated logs.

Treatment options include trunk injections, bark sprays, or soil applications. These are most effective when trees are actively growing and before temperatures get too hot. If you want to preserve your ash trees, early action is essential.

The invasive emerald ash borer (EAB) has recently been confirmed in Broken Arrow, placing ash trees in our region within its typical spread range. EAB is a non native beetle, known for causing extensive and often fatal damage to ash trees across the United States.
