Resumo: Chemical control is used to restrain the attack of weeds on cultivated crops in Brazil; however, the overuse of chemical products can cause damage to the crops. This study aimed to evaluate the phytotoxicity caused by pre-emergence (PRE) and post-emergence (POST) herbicides in sugarcane cultivars and their influence in agronomic and technological traits as well as to verify the existence of correlation between the herbicides effect and the measured traits. The experiment was carried out in a randomized complete block design with three replications, considering the factorial combination of five sugarcane cultivars and five control strategies, being four herbicides and one control. The sensitivity was evaluated at 30, 60 and 90 days after application, through a scale of intoxication symptoms. The herbicides with active ingredients diuron + hexazinone and ametryn presented more phytotoxicity effect; the cultivars RB867515 and SP81-3250 showed greater toxicity symptoms when exposed to the agrochemicals. Plant height was the only trait influenced by the herbicides. It was observed a significant correlation between the trait number of stems and phytotoxicity effect.

Com isso, objetivou-se avaliar a fitotoxicidade por herbicidas de pré-emergência (PRE) e pós-emergência (POST) em cultivares de cana-de-açúcar e sua influência em caracteres agronômicos e tecnológicos, além de verificar a existência de correlação entre o efeito dos herbicidas e os caracteres mensurados. O experimento foi conduzido no delineamento de blocos casualizados, com três repetições, considerando a combinação fatorial de cinco cultivares e cinco estratégias de controle, sendo quatro herbicidas e a capina manual. A sensibilidade foi avaliada aos 30, 60 e 90 dias após a aplicação, por meio de escala de notas de sintomas de intoxicação. Os herbicidas com os princípios ativos diuron + hexazinona e ametrina apresentaram maior efeito de fitotoxicidade; as cultivares RB867515 e SP81-3250 tiveram maiores sintomas de intoxicação quando expostas aos agroquímicos. A variável altura de planta foi a única influenciada pelo efeito dos herbicidas. Foi observada correlação significativa entre a variável número de colmos e o efeito de fitotoxicidade.Instituto Federal de Educação, Ciência e Tecnologia do Sul de Minas Gerais - IFSULDEMINAS2020-05-05T17:42:20Z2020-05-05T17:42:20Z2019-03info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfCASTRO, F.
