Potencial de uso dos herbicidas chlorimuron-ethyl, imazethapyr e cloransulam-methyl na cultura do feijão

Abstract: ); e testemunha sem herbicida]; e o da subparcela, os cultivares (BRS Grafite, BRS Horizonte, Pérola, BRS Pitanga, BRS Pontal, BRS Requinte, BRS Supremo, BRS Timbó, BRS Valente e BRS Vereda). As parcelas foram mantidas capinadas, para que não houvesse interferência das plantas daninhas. Os tratamentos com herbicidas foram fitotóxicos; todavia, de forma geral, os sintomas mais severos foram verificados no tratamento que continha chlorimuron-ethyl. A associação de fomesafen com chlorimuron-ethyl provocou as maio… Show more

“…In fact, there is several evidences that herbicide detoxification is responsible for many cases of tolerance of crop plants to herbicides, including corn to nicosulfuron (Liu et al, 2015), cotton to pyrithiobac (Snipes and Seifert, 2003), corn to mesotrione (Ogliari et al, 2014), and soybean to sulfentrazone (Walsh et al, 2015). There is evidence of tolerance of common bean to other ALS inhibitors (Procopio et al, 2009). The grain yield losses caused by the herbicide chlorimurom-ethyl on common bean plants from several varieties ranged from 0 to 55%.…”

“…The grain yield losses caused by the herbicide chlorimurom-ethyl on common bean plants from several varieties ranged from 0 to 55%. The herbicide imazethapyr has the potential to be selective to the common bean crop, despite crop yield losses up to 18% (Procopio et al, 2009).…”

“…Porém, os resultados observados na presente pesquisa não podem ser extrapolados para todos herbicidas do mesmo mecanismo de ação, visto que Procópio et al (2009) demonstraram que o chlorimuron-ethyl, imazethapyr e cloransulam-methyl, produtos que também agem inibindo a enzima ALS, foram tóxicos para algumas cultivares de feijoeiro, apesar de registrados para uso na cultura da soja.…”

“…provocaram níveis de fitointoxicação muito elevados. Para culturas onde o efeito da fitointoxicação causada pelo clomazone é elevado, têm se utilizado protetores ("safeners") visando a reduzir a fitointoxicação causada por este herbicida (Sanchotene et al, 2010). No entanto, até o momento existem poucas informações disponíveis a respeito da validade desta técnica para a cultura do feijão.…”

“…A aplicação de herbicidas no feijoeiro, na maioria das vezes, provoca sintomas de toxicidade nas plantas (Procópio et al, 2009). Contudo, existem diferenças na sensibilidade das cultivares ao uso de herbicidas (Wilson & Miller, 1991;Procópio et al, 2003).…”
