Pest identification
What's eating my saskatoon berry?
Birds
Signs: Ripe fruit harvested by robins, starlings, and cedar waxwings before the grower can pick.
Control: Net plants or entire rows from early fruit colour change until harvest; bird-scaring tape has limited effect against persistent flocks.
Pear slug / cherry slug sawfly (Caliroa cerasi)
Signs: Slimy, slug-like larvae graze upper leaf surface, leaving brown skeletonized patches.
Control: Dust with kaolin clay or wood ash to desiccate larvae; hand-pick; apply neem oil or pyrethrin for heavy infestations.
Saskatoon bud moth (Epinotia giganteana)
Signs: Larvae feed inside flower and leaf buds in spring, reducing fruiting potential.
Control: Monitor in early spring; remove and destroy webbed shoot tips; apply spinosad at bud-burst if moth pressure is confirmed.
