Herbicide investigations in coniferous tree nurseries in Saskatchewan and Alberta

In this paper I will provide a brief overview of the current research in weed control for the production of conifer seedlings and transplants in Alberta and Saskatchewan. Replicated weed control trials are being conducted at the PFRA. Tree Nursery, Indian Head, Saskatchewan; Alberta Tree Nursery (ATN) and Horticultural Centre (HC), Edmonton; and Pine Ridge Forest Nursery (PRFN), Smoky Lake, Alberta, although informal experimentation is occurring at other nurseries too. The overall objectives of the Indian Head and Edmonton trials are to reduce hand weeding to a minimum without jeopardizing crop safety or incurring phytotoxic soil residuals in subsequent crops. At Pine Ridge the major objective is similar, but more emphasis is being placed on herbicides as a standby procedure in the event of emergencies or if nonchemical methods would be too costly. Before I review the investigations now under way, I will briefly outline what weed control practices are being used in the production of bare-root conifer seedlings.
