Dr Alan Watson and his Weed Research Group have been developing biological weed control strategies using the weed's own natural enemies to control the weed. The goals of Dr Watson's research program are to understand the processes involved in host (weed) pathogen interactions, to investigate mechanisms involved in disease development and weed host response, and to use this knowledge to select, develop, and implement effective, safe, and sustainable means to reduce the negative impact of major noxious weeds in rural, urban, and natural environments. Velvetleaf (Abutilon theophrasti), dandelion (Taraxacum officinale) and common ragweed (Ambrosia artemisiifolia) are the major temperate species being studied in Canada. A bioherbicide product has been commercialized for control of dandelion (photo at left) and other broadleaved weeds in turfgrass. Research has gone beyond Canada into Southeast Asia and Sub-Saharan Africa to investigate biological methods for less developed nations and subsistence farmers. Significant progress towards effective biocontrol strategies for several rice weeds in Southeast Asia and a possible solution for Striga (witchweed) (photo at right), the major threat to African cereal crops, have been achieved.
