Table 3.
Evaluation of pre-emergence and post-emergence selectivity applied to vetch (Vicia sativa) plants during the 2019–2020 (GS1) and 2020–2021 (GS2) growing seasons. Phytotoxicity (%): plant susceptibility to herbicide on a scale of 1:100, where 1 depicts no injury on the crop and 100 depicts complete plant necrosis. Plant dry biomass (t ha−1) and grain yield (t ha−1). Coding of the herbicide treatment is as elsewhere.
