Fruit and Nut Diseases in Arkansas
The most common tree fruits grown in Arkansas include apples, peaches,
nectarines and plums whereas grapes, blueberries, blackberries, raspberries and
strawberries constitute the majority of small fruits. Pecans are the primary nut
crop grown in the state. The majority of the infectious diseases of fruits and
nuts are caused by some type of a fungus. There are a few important diseases
caused by bacteria and viruses. Many of these infectious or biotic diseases
produce characteristic symptoms. Symptoms are the visible response to a
particular disease agent. Common symptoms on fruit and nut crops include leaf
spots, blights, cankers, and rots on various parts of the plant. In some
instances, structures of the fungus or other agent may be apparent on the host
plant. Symptoms and signs are useful in diagnosing many infectious diseases of
fruits and nuts.
