Abstract
The size and yield of Bartlett pears was improved using several practices.
Chemical thinning was performed by naphthylacetamide application about 10 days after petal fall.
A split application of nitrogen fertilizer and adequate potassium fertilizer, boron and zinc micro nutrients aided in good leaf and tree growth without increasing susceptibility to fire blight.
Low rates of glyphosate herbicide were used to suppress sod ground cover in the summer.
Breaking out most of the current season’s sucker growth in the summer aided in the control of fire blight and the pear psylla insect, allowed better spray coverage, and decreased the amount of winter pruning.
A thorough removal of blighted branches after normal leaf fall, followed by detailed winter pruning and a late winter inspection for latent cankers aided in fire blight control.
