Integration of cultural and biological methods for control of postharvest decay in `Bosc' pears.

ABSTRACT

Five cultural or biological methods for control of postharvest decay of pear fruit were evaluated in 1991 and 1992. `Bosc' pear trees were treated with nitrogen fertilizer either in spring (high fruit N) or one month pre-harvest (low fruit N); either sprayed three times with CaCl2 solutions during the growing season, or not sprayed; fruit were harvested either at the beginning or end of the maturity period; fruit were wounded and inoculated postharvest with either water or with a cell suspension of the yeast Cryptococcus laurentii; and fruit were stored 2-3 months either in air or in 2% oxygen. The least decay was in fruit from trees treated with nitrogen fertilizer one month pre-harvest, with calcium chloride during the growing season, harvested early in the maturity range, inoculated postharvest with Cryptococcus laurentii, and stored in either air or 2% oxygen.
