Managing Pesticide-free Home Lawns
By Kathleen Dodson, MSc.
T he advent of cosmetic pesticide bans
within certain Canadian provinces has
resulted in a need for research examining
the efﬁcacy of using lawn maintenance
cultural practices without herbicides to maintain
ideal turfgrass populations.
The topic of weed control in turf was reviewed
by Dr. Phillip Busey, who found in 2002 alone,
more than 750 papers on the use of conventional
pesticides as the means of weed control were
published, but only 25 papers on the use of
cultivation methods. 1 This suggests there is a
gap in literature on the use of cultural practices
for weed management. An understanding of
weed encroachment and how to discourage
weed invasion is required.
