Abstract
The yield of potato, an important food security and income crop in Uganda is substantially affected by
pests. A survey was carried out in south western Uganda, a major potato growing area to assess the
distribution and severity of potato pests in June and July 2015. In addition, leaf miner management
options such as pesticide use, yellow sticky traps and mulching were evaluated for effectiveness. Trials
in leaf miner hot spots in Bukimbiri and Chahi sub-counties of Kisoro district were conducted in three
seasons during 2016 to 2017. In each sub-county, two sites were selected per season and trials were
established in a completely randomized design with each treatment being replicated three times. From
the survey, aphids and leaf miners were the major pests with high incidences in Kabale and Kisoro
districts and rarely encountered in Rukungiri and Kanungu. Use of Dudu-acelamectin reduced leaf
miner damage on leaves in season 1 (2017; P=0.001) and registered significantly higher yields
compared to other treatments. Yellow sticky traps trapped high leaf miner fly populations but leaf miner
damage on leaves and yield were not significantly different from control and mulched plots. Judicious
use of pesticides in high leaf miner populations together with yellow sticky traps can reduce leaf miner
populations and damage on potato.
