Producers can easily identify bacterial wilt, since it produces yellowish leaf tissue, and normally healthy plant leaves shrink and become cup-shaped. Plants with bacterial wilt also display a discoloration of the root system. Phytophthora root rot: Common especially in low lying fields and in . poorly drained, heavy soils. The disease gains a foothold when plants are submerged by excessive moisture for two or three days. Parker says the root system begins to discolor rapidly, turning from light brown to orange. Damage is swift, he says, since 70 to 80 percent of a crop can be killed in just two to three weeks following flooding. Anthracnose: Severe in the Mid- Atlantic region, anthracnose quickly is spreading to the Mid west. its spores are carried by winds, then deposited in the soils. During heavy rains, splashing pushes the diseases onto the stems of the alfalfa plants, forming enlongated, diamond-shaped locinnc Usually found during hot, TREAT YOUR WATER SUPPLY INCREASE YOUR PROFIT If your herd's water supply has high levels of nitrates, sulfates and/or bacteria your cows can not reach their full potential.

Verticillium wilt: Identified in the United States in 1976, Ver ticillium wilt is considered the most destructive disease in nor thern Europe. It has been iden tified in most northern alfalfa producing states, Parker says. Spores are carried by winds or farm machinery. Symptoms in clude curling leaves with yellow or pinkish discoloration that turn brown, die and drop from the plant leaving green erect stems. Crop rotation is one method of controlling certain alfalfa diseases, Parker says. Effective chemical controls are not available at this point. Parker emphasizes the only sure way to control diseases is through the selection of a disease-resistant alfalfa varieties, such as DKI2O, DKI3S or Advantage from DeKalb- Pfizer Genetics. Parker says other factors im portant to proper variety selection include winterhardiness, longevity, fast start, performance under wet and dry growing con ditions, regrowth and crude protein levels.
