Get rid of bad apples.
Fungal infections present an enormous risk to plants in your yard, and trees are no exception. No matter how strong and healthy your trees are, they’ll always be vulnerable to fungus, which can penetrate nearly every part of these organisms, spread through them, and deprive them of the nutrients they need to survive. Thus as a homeowner seeking a lush, beautiful yard, you need to be on the lookout for fungal diseases, and that starts with apple scab. The better you are at watching out for this infection, the easier it will be to keep your trees safe from it all year long.
Apple scab is a disease caused by Venturia inaequalis, a type of fungus that spreads during the spring. The disease is named after the fact that it frequently attacks apple trees, including crabapple and wild apple trees as well as orchard apple ones. It is notable for causing large lesions to form on leaves, which are dark in color and often resemble scabs. It is also highly contagious and can spread quickly among trees of a susceptible species that are planted near one another.
In order to spread, apple scab relies on large amounts of moisture in leaves. It is thus only a threat to Apple-related trees that allow humidity to penetrate the leaves without issue. As a result, it is relatively easy to modify apple trees genetically so that they are not susceptible to spores. If you plan to plant apple trees, you can eliminate the problem entirely simply by using the resistant variety. But if you already have apple trees that are not resistant to this disease, you must make a concerted effort to protect them, as apple scab can ruin their appearance and eventually kill them.
The most obvious symptoms of apple scab disease are the scabs themselves, which form on infected leaves and eventually cover them. These lesions are usually brown or black in cover, though you’ll occasionally find orange spots on the leaves as well. The spots will first appear in the spring and will grow larger and larger as the weather becomes warmer. As they grow larger, the leaves will begin to shrivel and fall off. By August, the tree may have suffered complete canopy loss, to the point that it cannot get any of the energy it needs from the sun. Let this go on long enough and the tree will die.
Safari Tree has extensive experience dealing with apple scab disease and can protect all the trees in your yard from it even if they are not resistant varieties. We combine apple scab treatments with preventative measures to stop your trees from getting infected in the first place, thereby minimizing the risk of a severe infection.
Despite these measures, the apple scab fungus may still find a way to take root in your trees. When this happens, Safari Tree offers comprehensive apple scab treatment, which involves:
Fungicide– Fungicides are chemicals that kill fungi wherever they are present. We select fungicides that are carefully tailored to apple scab disease. We then take care to identify the specific locations where apple scab has spread and treat those areas intensely. In this way, we apply apple scab control that can get rid of the fungus while causing minimal damage to the tree or to the surrounding environment.
Fertilization– In addition to treating the fungus, we work to reverse as much of the damage that it has done as possible. We thus apply copious amounts of fertilizer to your tree, along with watering it and otherwise making sure it has what it needs to grow. This way, your tree can quickly regain its full health, and the risk that another infection will develop and harm it will be minimal.
Isolation– While treating and fertilizing your tree, we remove any leaves that have fallen around it during the infection. This prevents the fungus from spreading to other trees in your yard so that a threat to one tree’s health does not endanger all of them.
