Selectivity of pre-emergent herbicides in sweet potato genotypes

Abstract: Sweet potato is sensitive to weeds and a chemical control is needed for high yield production. This work describes the evaluation of three sweet potato genotypes grown in pre-treated soil with clomazone, linuron, metribuzin mechanical weed control (MWC) and without weed control. Visual injury and yield of genotypes were examined, as well as production of branches and roots in fresh and dry biomass. Herbicide residues at root samples were determined by the LC-MS/MS method. The genotypes exhibited a different be… Show more

“…Plants propagated by seeds are less tolerant to herbicides in their initial phase, due to Palavras-chave: auxinas sintéticas, branqueamento, 4-hidroxifenilpiruvato dioxigenase (HPPD), plantas daninhas. their smaller size and reduced amounts of nutritional reserves when compared to plants from cuttings (MacNeill et al, 2017;Santos et al, 2018a;Costa et al, 2021). So, it is necessary to evaluate herbicide tolerance in elephant grass crops propagated by seeds to manage weeds efficiently and safely.…”
