Low doses of glyphosate and its effects on Commelina benghalensis growth
DOI: 10.7824/rbh.v7i2.61
With the objective of verifying the effect of low doses, simulating glyphosate herbicide drift in growth and initial development of Commmelina benghalensis, a study was conducted in greenhouse conditions. C. benghalensis was superficially sowed (approximately 2 cm) in small tubes filled out with substratum. After the germination, just one plant by tube was kept and treatments were applied. Treatments were constituted by different glyphosate doses, 2, 4, 8, 16, 20 and 24 g a.e. ha-1 and a check without application. By obtained results, it was possible to verify that, doses starting from 2 g a.e. ha-1 may cause effects in growth and development of dossel and roots of C. benghalensis plants.
