The slow growth of the pineapple (Ananas comosus (L.) Merr.) during the vegetative phase prolongs the crop cycle, resulting in higher production costs. When used in low doses, some herbicides can stimulate plant growth, a phenomenon known as hormesis. The aim of this study was to determine the effects of sub-doses of glyphosate and 2,4-dichlorophenoxyacetic acid (2,4-D) on growth in the Pérola cultivar of the pineapple. The treatments under study consisted of glyphosate applications of 0, 1.8, 3.6, 7.2, 18, 36, 72, 180, 360 and 720 g a.e. ha-1, and 2,4-D applications of 0, 1.68, 3.35, 6.70, 16.75, 33.5, 67, 167.5, 335 and 670 g a.e. ha-1. The experiments were completely randomised with four replications. The plants were grown in the greenhouse in pots with a capacity of 8 dm3 substrate. Growth variables were evaluated in the plants, together with the total and partitioned accumulated biomass (leaf, stem and root). The data were submitted to analysis of variance and regression. The pineapple showed greater phytotoxicity from the glyphosate herbicide at applications ranging from 18 to 720 g a.e. ha-1 and from 2,4-D in the range of 167.5 to 670 g a.e. ha-1. The hormesis effect was evidenced by the 32.25% increase in root fresh weight at the dose of 1.8 g a.e. ha-1 glyphosate. However, the slow growth of the pineapple was not overcome by the hormesis effect of the herbicides.

It is evident the increase in the occurrence of different stresses that impact agriculture and so there has been an increase in research to study stress mitigators including silicon (Si) and selenium (Se). However, the great challenge to be answered would be to assess whether it is possible to maximize these benefits by combining these two elements. Therefore, this review focused on discussing the feasibility of combining Se and Si in mitigating abiotic stresses and also measuring gains in yield and quality of agricultural products. These are the main challenges of plant mineral nutrition with these two elements for sustainable cultivation, ensuring food security with the possibility of improving human health. As the mode of application of an element can change absorption and assimilation processes and consequently the plant’s response, it is important to consider research with supply of these elements via the foliar and root route. Thus, we highlighted the potential of the combined application of Se and Si and whether or not they are relevant to overcome the individual application in stress mitigation or even in plants without stress. In addition, we pointed out new directions for research on this topic in order to reinforce the combined use of stress relievers and their potential benefit to crop plants.
