Resumo: An increase in crop productivity should be linked to the effective control of production costs. Thus, the chemical and selective control of weeds is an appropriate method because it saves labor and energy, requires little manpower, and allows control throughout the crop cycle. The present study aimed to evaluate the sensitivity of avocado seedlings to the phytotoxic effects of postemergence herbicide application. The experiment was carried out on avocado seeds of the cultivar Margarida in a greenhouse in the fruit sector of the Department of Agriculture, Federal University of Lavras. The experimental design was randomized block design, with four replicates and eight treatments, and each experimental plot consisted of three seedlings. The herbicides paraquat, oxyfluorfen, fomesafem, carfentrazone-ethyl, and glyphosate caused damage to avocado seedlings and should not be recommended based on the commercial dosage used. Paraquat caused the plants to die within 30 days after application. Fluazifop-p-butyl and imazethapyr proved to be the most promising for use in avocado orchards because they caused less damage to the crop.

Assim, o controle químico e seletivo das plantas daninhas é um método adequado, pois proporciona economia de trabalho e energia, demanda pouca mão de obra e permite o controle durante todo o ciclo de cultivo. O presente trabalho teve como objetivo avaliar a sensibilidade da cultura do abacateiro aos efeitos fitotóxicos da aplicação de herbicidas em pós-emergência. O experimento foi instalado utilizando-se de sementes de abacate da cultivar Margarida e conduzido em casa de vegetação no Setor de Fruticultura do Departamento de Agricultura, da Universidade Federal de Lavras. O delineamento experimental utilizado foi de blocos ao acaso, com 4 repetições e 8 tratamentos e cada parcela experimental foi composta por três mudas. Os herbicidas paraquat, oxyfluorfen, fomesafem, carfentrazone-ethyl e glyphosate causaram danos às mudas de abacateiro e não devem ser recomendados com base na dosagem comercial utilizada. O paraquat causou a morte das plantas em 30 dias após a aplicação. Os tratamentos com Fluasifope-p- butílico e Imazetapir demonstraram ser os mais promissores para uso em área de implantação de pomares de abacateiros pois causaram menores danos à cultura.Universidade Estadual Paulista "Júlio de Mesquita Filho"2022-06-27T22:32:10Z2022-06-27T22:32:10Z2022-03info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfSILVA, D.
