Trees are living things, which means that they are susceptible to disease. Plant diseases are often caused by fungi and can develop over time. The tree could even die as a result. Diseased trees on your property could have you thinking, “Could an arborist near me Weston CT diagnose and take care of this tree?”
Most likely, the answer is yes. To know when to make the call, it is helpful to know what symptoms could mean. Here are examples of common tree diseases in the United States.
There are a number of fungal pathogens that could cause a tree to develop powdery mildew. The spores and fungal threads grow on the leaves and other surfaces of the plant, forming a powdery-looking white residue. Young trees are particularly susceptible to powdery mildew, which can cause defoliation and stunted growth. You can avoid it by not overcrowding your trees or planting them in shady areas.
Crabapple trees are susceptible to apple scab. It gets its name from the lesions that form on the leaves, resembling scabs. Infected trees could lose their leaves prematurely. You can treat apple scab by applying fungicide, but you must act quickly as this condition occurs early in the season.
Dogwood and sycamore trees are particularly vulnerable to anthracnose, but it can affect a variety of North American tree species. Flowers, fruits, leaves, twigs, and essentially all above-ground parts of the tree may bear the scars of battle from the fungal pathogens that cause anthracnose. Eventually, anthracnose infection can kill a tree. Prior to that, it can cause dieback of the branches or premature loss of the leaves. Treatment of anthracnose may involve applying fungicides to the leaves or injecting them directly into the trunk. Antifungal trunk injections should only be handled by a professional.
