The inadequate use of herbicides may cause serious and sometimes chronic poisoning due to long exposure to low levels of toxic ihtoxicacion.

Herbicides may also be teratogenic, mutagenic, cancerigenous agents and endocrine disruptors, with the occurrence of neurodegenerative diseases and reproduction disorders. Several studies have shown that melatonin has antioxidant, anti-inflammatory and immune-modulating qualities, besides affecting the reproduction system. Solutions that prevent or minimize cell lesions caused by several biological systems have been focused upon in the treatment for poisoning with herbicides.

Thus, melatonin, a known antioxidant, may be an alternative against the poisoning by single or associated herbicides. Neste contexto, Dallegrave et al. Desta forma, inicia-se o glifoato redox Bus et al. Assim, Rouimi et al.
