Foliar calcium sprays are recommended for bitter pit suscept-

 Delicious, especially on trees with a light crop or those that have 

 produced pitted fruit in recent years. 



We recommend using calcium nitrate (fertilizer or technical 

 grade) at the rate of 5 pounds per 100 gallons of water. A spreader 

 or wetting agent such as Triton B shoul d be used at the rate of 3 

 fluid ounces per 100 gallons of water.

 case are calcium sprays a substitute for lime on acid soils .
