The Farm Safety Association also encourages farmers to mark their equipment with reflective tape to increase visibility when traveling after dark. The new recommended colours for agricultural machinery in Canada are red and amber. Together with the new Slow Moving Vehicle sign and use of appropriate lighting, travel on Ontario's roadways will become much safer for farm operators and the public. The amount of fruit showing bitter pit symptoms coming out of storage over the winter was discouraging for many growers. Bitter Pit is a physiological disorder as opposed to a disease.
Some cultivars are more prone to the problem than others.
Northern Spy and Cortland are prone to this problem but Red Delicious, Idared, Crispin, Jonagold, Gala and Empire, among others, can also be effected. Growers will often apply 4 or 5 calcium foliar sprays, spaced 10 to 14 days apart beginning in early July, in hopes of defeating this problem. In spite of best intentions, some years, this is not enough to reduce fruit losses to an acceptable level. Boron is involved in the movement of Ca to the fruit. If B is low, Ca disorders are more prone to develop.
