2009 Herbicide Trials in Grass Seed Crops

Options for Chemical Weed Control in Perennial Ryegrass and,Timothy

Control of Japanese and Downy Brome in Perennial Ryegrass and control of Night Flowering Catch-Fly in Timothy are seen to be priorities in the grass seed industry.  MFSA is investigating control measures in the form of herbicides.



Trials will be carried out using the MFSA bike sprayer in 3m by 6m plots, following a random complete block design with 4 replicates. Two PRG sites have been chosen around Beausejour, two Timothy sites were chosen around Arborg and Fisher Branch. The products and rates used can be found in the tables 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.

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 Crop
