| ABSTRACT: In literature, there are few studies evaluating the response of different bean cultivars to herbicides, particularly the ALS enzyme inhibitors. The objective of this study was to evaluate the selectivity of common bean cultivars to the herbicide ethoxysulfuron and to select cultivars that are more tolerant to it. An experiment was conducted in a greenhouse, in a completely randomized experimental design with four replications. Factors consisted in 20 bean cultivars (IPR Eldorado, IPR Siriri, IPR Gralha, IPR 81, IPR Uirapuru, IPR Colibri, IPR Tuiuiú, BRS Esplendor, IPR Tangará, IPR Juriti, IPR Corujinha, IPR Andorinha, IPR Curió, BRS Campeiro, BRS Pérola, BRS Notável, BRS Estilo, UTF 3, UTF 5 e UTF 6), and four doses of ethoxysulfuron (0, 50, 100... |

| ABSTRACT Weed resistance to herbicides is a major global problem for agriculture. In recent years, the increased use of herbicides, without proper planning, has led to a large increase in the number of cases of weed biotypes that are resistant to one or more herbicide mechanism of action. Wild poinsettia biotypes (Euphorbia heterophylla), discovered in the State of Paraná, with resistance to herbicides that inhibit protoporphyrinogen oxidase (PROTOX) and acetolactate synthase (ALS), are the first case to exhibit multiple resistance in Brazil. This study analyzed the genetic inheritance of PROTOX inhibiting herbicide resistance in E. heterophylla. Crosses were conducted between biotypes that were susceptible (female parent) and those carrying multiple... |

| ABSTRACT: The characteristics of multiple resistance in Euphorbia heterophylla biotypes to herbicides that are inhibitors of ALS (Acetolactate synthase) and PPO (Protoporphyrinogen oxidase) and their responsible mechanisms are still not completely elucidated. The objectives of this study were to identify cross-resistance to herbicides from different chemical groups of ALS inhibitors (imidazolinones, sulfonylureas, pyrimidyl benzoates and sulfonanilides) and also PPO inhibitors (diphenylethers, phthalamides, oxadiazoles, triazolinones and pyrimidinediones) in E. heterophylla biotypes with multiple resistance to these herbicides; to analyze whether the antioxidant enzymes superoxide dismutase (SOD) and peroxidase (POD) constitute mechanisms that are... |
