Herbicide Screening of five spring-applied herbicides for use in established Red Clover grown for Seed Production in northeast Saskatchewan, 2019
Objective/Rationale: To evaluate crop tolerance and weed control efficacy of potential spring applied herbicides for use in established red clover, in support of registration under the Minor Use Program.
Methodology: This small plot research trial was conducted in a randomized complete block design with 4 replicates. Each plot was 2m by 7m with borders on each end. There were 11 treatments consisting of 5 different herbicides: Authority, Embutox, MCPA Amine 600, Buctril M, and Valterra (Table 1). Each herbicide was applied at a 1X and 2X rate. An untreated control (0x herbicide applied) was also used.
