This project would not have been initiated without the involvement of NSW DPI District Agronomists and management staff. The technical expertise in establishing collection and testing protocols, and resistance testing was performed by John Broster, Graham Centre. The involvement of Tegan Muirhead (NSW DPI) in help collecting and collating samples was greatly appreciated. Ag Grow Agronomy and Research would like to formally acknowledge all farmers involved in the project, and agronomists John Ronan and Heath McWhirter (Elders), Peter Hill and Thane Pringle (Yenda Producers Coop), Chris Lvitzke (Landmark), Allan Jones (Agronomic Business Solutions) and Pat Connell (PC Agronomy) for submitting samples and being involved in the extension of the project. |

Seed treatment |
For the 102 ryegrass samples, 0.2 g of seed was planted in plastic punnet trays (330 x 280 x 60 m). Each tray contained 14 different samples sown in rows 25 mm apart and 5 mm deep then covered. Trays were filled with either 50:50 peat:sand mix or soil mix (50:50 loam:river wash sand) depending on the herbicide to be applied. Two weeks after sowing all samples screened to post-emergent herbicides were counted and thinned to a maximum of 20 plants per sample. Sow thistle samples were sown in February 2013. Approximatley 50 seeds from each of the samples were planted in plastic trays (150 x 100 x 60 mm). Trays were filled as previously. |
Other trial notes |
This project was originally established between NSW DPI and GRDC; however, as a result of structural changes in NSW DPI, Ag Grow Agronomy and Research was contracted to complete the project. |
