Scarring of the rind of citrus fruit can prompt packinghouse operators to downgrade the fruit from fancy to choice or even juice.  If you as the grower can recognize the different types of scars you can differentiate between symptoms that indicate biological (e.g., insect, mite, disease, or snail), mechanical (e.g., equipment, hail, or wind rubbing), or chemical e.g., phytotoxic burn) damage. Once you know the causal agent you can take steps to reduce injury to future crops.
