2009 Herbicide Trials in Alfalfa Seed Crops

Options for Chemical Weed Control in Alfalfa seed crops

Control of Canada thistle in Alfalfa is still a large concern for seed producers. MFSA is investigating control measures in the form of herbicides.
 
Spraying will be completed by using the MFSA bike sprayer in 3m by 6m plots, following a random complete block design with 4 replicates.  Two alfalfa sites were chosen around Arborg and Fisher Branch. The products and rates used can be found in the table below.








































Trials will be monitored after spraying and rated for crop tolerance and weed control efficacy at 7, 14 and 21 days after spraying. The samples will be harvested when mature, threshed and cleaned, then analyzed for yield comparisons.

Results will be published in the Winter issue of  “Forage Seed News” and presented at the Manitoba Forage Seed Association Conference being held at the Victoria in on
January 10& 11, 2010.

Acknowledgments: We would like to thank all of the producers who have agreed to let us conduct these trials on their land. The MFSA could not carry out our research without the generous donations of our producers.  Further, the MFSA would like to thank the chemical companies that have generously donated sample product for our 2009 trials: thank you to Bayer CropScience.
