Chemical safeners may be used to increase the tolerance of crops to herbicides, when applied as seed treatment, as well as in mixed or formulated joint to the herbicide. The mechanisms of action of these safeners are related to the reduction in the absorption and/or translocation, metabolization and to the competition with the site of herbicides action. This review aims to describe the ways of use, action mode, limitations and future perspectives for using safeners as an additional tool to […]

The present review aimed to collect information from main studies about carryover effect of some herbicides in different crops. Therefore, some relevant subjects were discussed to better understand herbicide dynamics in soil such as the ionization equilibrium constant (pKa/pKb), octanol/water partition coefficient (Kow), solubility, vapor pressure, Henry’s constant (H), half-life and the interaction among these properties. From these points, it was developed the review about the residual effects of several herbicides such as imazaquin, imazethapyr, sulfentrazone, nicosulfuron, fomesafen and other, […]
