Simulated derive of glyphosate in green onion plants (Allium fistulosum L.)

Abstract

The effect of simulated glyphosate drift on common chives (Allium fistulosum L.) was evaluated. The work was developed in a private garden, in Confresa-MT, from January to February 2016. The experiment consists of 6 treatments with 4 repetitions, arranged in a completely randomized design (DIC). The treatments were formed b 6 sub doses of glyphosate: 0,54,108,162,216 and 270 g.i.a ha-1 . At 7 and 14 days after application of the sub doses of the herbicide glyphosate, the plants were subjected to visual analysis of phytointoxication, using notes, on a scale ranging from 0 to 10. At 14 days after application of herbicide, the number total leaves, number of dead leaves, number of tillers, fresh weight of commercial leaf and root length.
