Dr.
Al HamillResearch Scientist, Weed Management
Greenhouse Processing and Crops Research Centre, Harrow ON.
Research Interests:
Current research concentrates on the integration of weed management
into conventional and no-till (conservation till) production systems
for corn, soybeans, tomatoes and sugarbeets for Southwestern Ontario.
He also plays an integral role in the Minor Use registration for numerous
herbicide treatments for use in tree fruit new plantings, mature orchards,
tomatoes and seed corn.

ON.
Research Interests:
Evaluation of new herbicides for use in field and horticultural
crops. Determine the spectrum of weeds controlled and crop safety.
Evaluate weed management programs in herbicide resistant crops such
as Roundup Ready corn and Roundup Ready soybeans. Develop weed management
strategies for the control of problem weeds in corn, soybeans and
wheat. Determine the effect of crop row width and seeding density
on weed management. Determine the impact of long-term weed management
systems on weed shifts.

J. SwantonProfessor
University of Guelph, Department of Plant Agriculture
Research Interests:
My research goal is to facilitate the integration of ecological
principles into crop production systems. My major area of research
has been to design and implement integrated weed management systems
for field and horticultural crops grown in Ontario. Selected areas
of study have included weed and crop modelling, weed biology and ecology,
economics of weed management and managing weeds with herbicides.

Research Interests:
My main interest is currently in the understanding of herbicide
resistance in weeds. This includes topics such as:

Research Interests:
My research focuses on weed biology and ecology, and the development
of integrated weed management systems in field crops. We conduct field
and laboratory experiments to determine seed germination requirements,
emergence patterns and seed production of different weed species in
relation to crop management practices. Another objective is to quantify
crop yield losses and establish economic thresholds for various weed
species in soybeans and corn. This has led to the release of decision
support software for weed management in these crops

Weed Management Lead Ontario Ministry of Agriculture and Food - Guelph, ON
My goal is to identify the major weed management issues facing the Ontario Grower and then work with our awesome team of weed researchers to provide practical, economical and environmentally responsible solutions.
Researchers at the University of Guelph and Agriculture and Agrifood Canada are fortunate to have an amazing team of field technicians. Without them, the field work would simply not get done at the high level that it does.
