ABSTRACT
An autumn application of dolomitic lime to infected leaves on the orchard floor resulted in a decrease in the percentage of apple and pear leaves with pseudothecia, the number of pseudothecia per leaf, and the number of asci per pseudothecium of Venturia inaequalis and V. pirina. A dolomitic lime application of 5.08 metric tons per hectare reduced the ascospore dose the following spring up to 88% for pear and 92% for apple.
