Herbicide Screening in Red Clover and Perennial Ryegrass
Objective: To determine the tolerance of established red clover to a number of post-emergence herbicides. Three studies were conducted in the Arborfield – Carrot River; however, seed yields were obtained only at the two Arborfield sites.
Conclusion: At the first rating date, Pardner caused just acceptable injury at the 2X rate. Unaccpetable injury was recorded at the 2X rate of the Pardner / Imazamox (Solo) tank-mix for the first three ratings. At the 2nd and 3rd rating date, the 2X rate of Odyssey also caused unacceptable injury.
