ROTS
Rots are diseases that decay roots, stems, wood, flowers, and fruit. Some diseases cause leaves to rot, but those symptoms tend to be described as leaf spots and blights. Rots can be soft and squishy or hard and dry. They are caused by various bacteria and fungi. Many are very active in stored fruits, roots, bulbs, or tubers.
Fruit RotsRots are diseases that decay roots, stems, wood, flowers, and fruit. Some diseases cause leaves to rot, but those symptoms tend to be described as leaf spots and blights. Rots can be soft and squishy or hard and dry. They are caused by various bacteria and fungi. Many are very active in stored fruits, roots, bulbs, or tubers.
Grapes infected with black rot turn brown, then harden into small, black, mummified berries. Brown rot of stone fruits causes whole fruit to turn brown and soft. Control fruit rots by planting resistant cultivars, removing and destroying infected fruit, and pruning to increase air movement. Applying compost tea or Bacillus subtilis may help prevent the disease from developing. Sulfur sprays throughout the season can be effective, too, as a last resort.
Root + Stem Rots
Control these troublesome rots by providing good drainage and good air circulation. Try drenching the soil with beneficial fungi or bacteria. Start cuttings in sterilized mix, and plant only healthy plants. Dispose of all infected plant material. Winter injury may invite problems on woody plants.

Mushroom + Wood Rots
These rots can damage or kill trees. Some of them form obvious mushrooms or other fungal growths. Cutting out infected areas can provide control. Keep soil well drained, and plant resistant species and cultivars where problems are severe.
