"Bitter-pit is associated with boron metabolism of the plant, and it can be effectively reduced by boron sprays. Boron sprays applied during the blossoming period resulted in the following:

a. Significant reduction of the percent of fruits showing deep-pit and the number of deep-pits per fruit at harvest as well as the development of deep-pit in stored fruits.

b. Striking development of good red color and smooth finish.

c. Reduced skin cracking." 1
