Abstract: O objetivo deste trabalho foi verificar a seletividade de herbicidas utilizados em áreas de eucalipto sobreo crescimento de Myracrodruon urundeuva. O experimento foi conduzido em casa de vegetação em duas épocas diferentes (2002 e 2003), em delineamento inteiramente casualizado, arranjado em esquema fatorial (5x4), sendo cinco herbicidas em quatro doses, com seis repetições. Os tratamentos, com as doses, foram: haloxyfop-methyl (0,00, 120, 240 e 480 g ha-1), sulfentrazone (0,00, 300, 600 e 1.200 g ha-1), isoxa… Show more

“…With intoxications from 21-30, 31-40 and 41-50%, TuffiSantos et al (2007) report that a reduction in the volume of timber of 18, 26 and 48%, respectively, may occur in eucalyptus. As for glyphosate, phytotoxicity levels were lower, differing from the study carried out by Duarte et al (2006), who In Handroanthus albus seedlings (Table 3), both herbicides caused significant damage, despite the tolerance of the species to the lowest glyphosate level.The Imazapyr herbicide can be considered selective to the seedlings of Handroanthus albus in its lower dosage, since, even when chlorosis occurred,, it did not inhibit the emission of new leaves or plant recovery. However, imazapyr at 4 L ha -1 caused phytotoxicity to seedlings of Handroanthus albus in all assessment periods.…”

“…Procópio et al (2003) já observaram a mesma tendência nas variedades de cana-de-açúcar e soja em relação aos herbicidas. Segundo Duarte et al (2006), isso pode estar relacionado à diferença na penetração do produto na planta. A penetração dos herbicidas nas plantas é essencial para sua eficiência e pode ocorrer através dos tecidos vegetais (estruturas aéreas e subterrâneas), pelas sementes, pela radícula e pelo caulículo (SILVA, 2000).…”

“…Segundo Alves et al (2000), os efeitos de fitotoxicidade observados para este herbicida ficam restritos aos locais de contato ent re o pro dut o e a pla nta, não hav end o evolução dos efeitos com o desenvolvimento das plantas. Avaliando a seletividade de herbicidas sobre mudas de Myracrodruon urundeuva, Duarte et al (2006) verificaram, aos 14 DAA, sintomas lev es de int oxicaç ão par a doses de 720 e 1.400 g ha -1…”
