Identifying apples diseases and disorders
Identification of apples diseases and disorders usually takes place by looking to the symptoms. Some symptoms are visible from the outside, while others can only be found internally after cutting the apple. Photos are available to help with identification. For apple growers and storage locations it is important to detect quality problems as early as possible. In this way they can adapt orchard or storage conditions to reduce the incidence. Also retailers can benefit from knowledge about disorders which they may encounter. For them it is important to know whether the cause lies in a previous stage in the supply chain or is due to their own operations.
BruisingBruising is often visible as pressure points that appear as circular depressions in the skin. Initially no discoloration occurs, but the tissue of the pressure point turns brownish after a few hours in warm temperature. This may or may not be visible from the outside. Careless handling can easily lead to this damage, in all parts of the supply chain.
PuncturesPunctures in the skin are often caused by rough handling. Examples of causes are puncture with the stem of a neighbouring apple, by fingernails or by sharp edges of crates. This can happen anywhere in the supply chain and can be prevented. Open wounds are most sensitive for fungal infections.
