Reducing lenticel blotch in apples
Fruit sprays of calcium, along with soil supply, will help reduce lenticel blotch incidence in apples. The greater the number of sprays the better the fruit quality. It is important to continue spraying right through to harvest.
In trials, foliar manganese, applied at least twice in the spring, has proven to be most effective at minimizing leaf drop and lenticel blotchiness.
