What is Brown Rot Blossom Blight?
Brown rot blossom and twig blight is a fruit tree disease that is caused by the fungus Monilinia fructicola. This blight, if left unchecked, can destroy stone fruit trees in your garden or orchard. Another type of brown rot blossom and twig blight, called European brown rot, is caused by the Monilinia laxa fungus. This type seems only to attack sour cherry trees. If a tree in your yard is infected by the brown rot fungus, you will notice. You will see cankers and rotten fruit appear on the trees. The first damage appears in spring as the flowers get infected. They brown and wilt without falling and can be covered in masses of spores. These spores can spread the infection to new foliage and twigs. The foliage and twigs are much more likely to develop the disease if they remain wet for more than five hours.
Controlling Brown Rot Blossom Blight
If your trees show signs of brown rot blossom and twig blight, you have a reason for alarm. You may be wondering about ways of controlling brown rot blossom blight. If you want to know how to treat brown rot blossom blight, a key to the management of this disease is practicing good sanitation. Brown rot blossom blight treatment begins with a clean garden. Since the disease is spread by spores, it is essential to limit the number of fungal spores in your yard. Controlling brown rot blossom and twig blight requires that you cut out or remove all rotted fruit from the area as soon as you see it. You’ll also want to remove all fallen fruit, as well as mummy fruit still hanging on the tree. Use sterilized pruners to clip out cankers in winter, while the trees are dormant. Burn all clippings and removed fruit or dispose of them in a way that prevents the spores from attacking other trees. Fungicides are an essential part of brown rot blossom blight treatment. In order to control this disease, you need to begin a fungicide spray program as soon as the trees begin to flower. Continue to use the fungicide throughout the growing season.
