Resumo
Glyphosate is an agrochemical from the group of phosphonates widely used as an herbicide. Although
it kills almost any plant, it can be used to eliminate weeds during the growing season of commercial
crops resistant to glyphosate. This research aimed to evaluate the toxicological effects of the herbicide
using seeds of parsley (Petrosolium sativum), lettuce (Lactuca sativa) and coriander (Coriandrum
sativum.) In the toxicological test was used twenty seeds each, dampened with glyphosate, evenly
distributed in containers with lids. The containers were left in a dry and airy place, and it was watered
once a day for 5 days. It was possible to check the toxic effect in the germination and growth of the
seeds provoked by the glyphosate, such as: for parsley (Petrosolium sativum) at concentrations
above 90 mg.L-1, for lettuce (Lactuca sativa) seeds at concentrations above 4 mg L-1 and for coriander
(Coriandrum sativum) seeds in concentrations above 12 mg L - 1. With these results it was possible to
conclude that the seeds studied were very sensitive to glyphosate. Also, these seeds can be used as
a reference for toxicity testing.
