Abstract
Trials were conducted on 11-year-old trees of ‘McIntosh’ apple ( Malus domestica, Borkh.) in Creston, British Columbia, to analyse the thinning effects of the blossom spray sodium 4,6-dinitro- ortho-cresylate (DNOC), and single and combination treatments of the post-bloom sprays naphthalene acetic acid (NAA), naphthaleneacetamide (NAD), and 1-naphthyl-(N-)methyl carbamate (carbaryl). DNOC was ineffective as a thinning agent when used alone. NAA did not significantly affect numbers of remaining fruit when used alone or with NAD or carbaryl. NAD showed significant thinning effects when applied alone or with carbaryl. Carbaryl was an effective thinning agent when used alone. The effects of carbaryl alone and carbaryl with NAD were found to persist after spacing the fruit on the branches by hand.
