Preventing and Treating Diseases in Deciduous Fruit

Deciduous fruits consist of peaches, pears, plums, nectarines and apples. Deciduous fruit farming can be ravaged by diseases that effect pear, plum, peach, nectarine and apple trees. Diseases can destroy the crop very quickly.

At certain times of the year, the farmer needs to be on the lookout for certain diseases that can affect his trees and his crop. There are two main types of diseases that affect deciduous fruit:

  • Fungal
  • Bacterial

The most common ones are Apple Scab and Powdery Mildew, which are fungal diseases. They are the most common and damaging disease for pears and apples. Another big problem is powdery Mildew which affects both Pome and Stone fruit and is especially damaging to peaches, apricots and nectarines.

The main method of keeping diseases out of the orchard is to use a preventative programme.
Insufficient photosynthesis can also diminish the flavour and size of the fruit.
There are a few bacterial diseases that affect fruit trees. Bacterial diseases can only be treated using antibiotics, which is illegal in most parts of the world. So the only way to prevent them is to build up the immune system in the tree by feeding and watering it well.
Building up the tree’s immune system will make it stronger and able to resist these bacterial diseases. This video takes an in-depth look at ways of treating diseases in an orchard on a farm.
