There is nothing quite as disappointing as adding a new plant to the garden only to have it fail due to pests or disease. Common diseases such as tomato blight or sweet corn stalk rot may often discourage gardeners from trying to grow these plants again. We take these diseases as personal failures but, in truth, even experienced commercial farmers experience these problems. Stalk rot in sweet corn is so common that it causes about a 5-20% commercial yield loss every year
