Impact of Thrip Populations in Canola

Researcher:

Dr. Owen Olfert, Dr. Bob Elliott and Murray Braun, Agriculture and Agri-Food Canada, Saskatoon

Project Code:

CARP-SCDC-11/00-06

Final Report:

May 2002

Summary:

Thrips feed on flowers and buds of a range of crops. In canola, pods damaged by thrips are often curled and tend to drop prematurely. Although the research showed insecticide treatments could control thrips for a short time, there were no significant differences in yield between treated and untreated plots. Plant sampling also proved to be a better monitoring tool than sweeps.
