Bacterial blight is an infectious plant disease that attacks many varieties of plants. The symptoms of blight may include browning and spotting of leaves, leaves becoming yellow and withered, and possibly total death of the plant's leaves, fruit, flowers, and stems. In severe cases, an entire plant may die if it has blight. Whole orchards of American chestnut trees died in the early 1900's, virtually making the species extinct by the late 1940's. Bacterial blight was the cause of the Irish Potato Famine in the early 1700's.
Caused by bacteria, blight festers in moist, cool environments. Some measures taken to control blight proliferation are using disease-free seeds and stock, blight-resistant plant species, crop rotation, spacing for better air circulation, and application of fungicides. Making sure that you grow your plants in sanitary conditions can also help correct bacterial blight.
If you suspect that your plants or lawn have bacterial blight, it is important that you deal with it quickly in order to prevent the spread of the disease. Here are some tips to help you correct bacterial blight in your landscape:
