Dormant Oil Sprays for Fruit Trees


There are a number of dormant sprays used on fruit to control various diseases and insects, but a dormant oil spray is designed to control scale insects. If you have a problem with scale, now is the time to start looking for an opportunity to spray. Normally spray should be applied by March 1, especially with peaches and nectarines. Apples are tougher, and application may be delayed up to the green tip stage. Temperatures need to be at least 40 degrees so spray has a chance to dry before freezing. If the spray does freeze before it dries, plant injury can occur. Applying the spray during the morning will help insure that it dries properly. Thorough coverage of limbs, branches and twigs is vital for good control.
