Abstract
No controle de plantas daninhas em pós-emergência na cultura da soja RR®; misturas de latifolicidas com o glyphosate têm sido utilizadas principalmente para melhorar a eficácia sobre espécies de difícil controle, a fim de se obter controle residual ou prevenir o surgimento de resistência. Este trabalho teve o objetivo de avaliar a eficácia de glyphosate isolado ou em mistura com latifolicidas para o controle de Euphorbia heterophylla e Ipomoea grandifolia, em dois estádios de desenvolvimento (1 a 3 folhas e 4 a 6 folhas). Para isso, foram realizados quatro experimentos em casa de vegetação, com glyphosate nas doses de 480 e 960 g e.a. ha-1; isolado ou combinado com os latifolicidas cloransulammethyl (30,24 g ha-1 ), chlorimuronethyl (12,5 g ha-1 ), imazethapyr (80 g ha-1), fomesafen (62,5 g ha-1 ), lactofen (72,0 g ha-1), flumiclorac-pentyl (30,0 g ha-1 ) e bentazon (480 g ha-1), em delineamento inteiramente casualizado, com quatro repetições. Em ambas as espécies, a utilização da dose de 960 g e.a. ha-1 do glyphosate dispensa a necessidade de misturas com outros herbicidas quando os tratamentos são aplicados no estádio de 1-3 folhas. Para aplicações realizadas em E. heterophylla no estádio de 4-6 folhas, aumentos da eficácia de controle em relação ao glyphosate aplicado isoladamente a 480 g e.a. ha-1 foram observados com as misturas com inibidores de protox. Para I. grandifolia em estádio de 4-6 folhas, os herbicidas fomesafen e flumicloracpentyl reduziram a eficácia de controle quando adicionados ao glyphosate a 480 g e.a. ha-1. Já as misturas contendo glyphosate a 960 g e.a. ha-1 proporcionaram incrementos da eficácia de controle. De forma geral, o controle das espécies E. heterophylla e I. grandifolia foi melhor quando os tratamentos foram aplicados no estádio de 1-3 folhas tanto pelo glyphosate (480 e 960 e.a. g ha-1) isolado como em mistura com os demais herbicidas.
Mixtures of broadleaf herbicides and glyphosate have been adopted during post-emergence weed control in RR® soybeans mainly to improve the efficacy of this herbicide when applied on tolerant weeds, to provide residual weed control or to prevent the selection of resistant biotypes. This work aimed to evaluate the efficacy of glyphosate alone or in tank mixtures with other broadleaf herbicides to control Euphorbia heterophylla and Ipomoea grandifolia, at two growth stages (1-to-3 leaves and 4-to-6 leaves). Thus, four greenhouse assays were carried out: glyphosate (480 and 960 g a.e. ha-1) applied alone or combined in tank mixtures with chloransulam-methyl (30.24 g ha-1 ), chlorimuron-ethyl (12.5 g ha-1 ), imazethapyr (80 g ha-1 ), fomesafen (62.5 g ha-1 ), lactofen (72.0 g ha -1), flumiclorac-pentyl (30.0 g ha-1 ) and bentazon (480 g ha-1 ). All experiments were arranged in a randomized block design, with four replicates. For both weeds, the use of 960 g ha-1 of glyphosate alone was sufficient, when application was performed at 1-3 leaf stage. For applications performed at 4-6 leaf stage for E. heterophylla, increased weed control in relation to glyphosate applied alone can be achieved by using mixtures with protox inhibitors. In relation to I. grandifolia at the 4 6 leaf stage, fomesafen and flumiclorac-penthyl decreased weed control when added to glyphosate at 480 g a.e. h-1. On the other hand, mixtures containing glyphosate at 960 g a.e. ha-1 provided increased weed control. In general, control of E. heterophylla and I. grandifolia was improved when herbicide treatments were applied at 1-3 leaf stage, either using glyphosate alone or mixed with other broadleaf herbicides.
