Anthracnose covers a few different specific disease pathogens and is the most common type of leaf disease in the world, affecting all turf types as well as trees, shrubs, and all other types of plants. In turf, anthracnose tends to affect older leaf tissue though it can affect immature turf as well. This particular disease can affect turf in both cool, wet weather as well as hot, dry weather though symptoms differ depending on the weather. In cool, wet weather anthracnose can cause basal stem rot where stem lesions darken and spread to the crown, leaving scattered small patches of damaged grass that turn yellow or brown before dying. In this situation, leaf tissue easily removes from the crown of the grass plant and the blackened crown is readily visible. In hot, dry weather with high humidity, anthracnose readily infects leaf tissue, turning grass blades yellow and tan as they die off. This can cause damage in irregular shaped patches that vary from small to very large, and grass blades also at times will exhibit oblonged red-brown lesions. Overall, patches affected in the summer tend to turn reddish brown, then yellow, tan, and finally brown at death. While grey-black mycelium is present with anthracnose, it usually requires a microscope to be seen, and a microscope is usually required to positively ID anthracnose in turf. Conversely, on trees and shrubs anthracnose can often be much more easily diagnosed. Many common trees including sycamores, ash, elm, oak, maple, walnut and dogwoods get anthracnose extremely regularly. Anthracnose damage in trees and shrubs start as irregularly shaped dead areas on leaves which can cause leaves to twist and deform as well as drop early. The lesions are generally black or purple and start along the veins of leaves, often at the tips of the leaves. Trees like sycamores often get anthracnose every year, and even if they defoliate they will push out a second set of leaves midseason and survive with no ill effects. Trees generally only suffer long term damage from anthracnose when they are infected so bad that new shoots of branch growth are affected, branch dieback occurs, or cankers are caused, all of which are things that can happen from anthracnose. Dogwood trees are perhaps the one tree found in landscapes that is most aggressively affected by anthracnose. In wet weather, Florida Dogwoods can be highly susceptible to anthracnose, with flowers becoming sparse and dotted with black lesions, as well as leaves turning black/purple at the tips and shriveling, almost appearing as it burnt by fire at the tips. Unfortunately, this disease is not treatable in many species, and the best course of action for anthracnose prevention in trees in particular is to plant resistant varieties. Whether discussing sycamore, London planes, or dogwoods, the variety you choose can go a long way in disease prevention. In particular, when it comes to ornamental dogwoods, always choose the most disease resistant Kousa variety over the highly susceptible Florida variety. When you are looking for how to treat anthracnose or how to prevent it, host plant matters quite a bit. Professional fungicides can be effective in all types of turfgrass and are highly recommended. When treating trees and shrubs, treatments must begin before bud break and applied regularly, and even then, success will only be achieved with certain species and useless with others.
