Recovery capacity of African star grass after application of glyphosate in pre-sowing of corn

The objective of this work was to evaluate the recovery capacity of African star grass (Cynodon nlemfuensis) after glyphosate application in pre-sowing of corn. A randomized block design was used, with four replicates. The treatments were doses of acid equivalent (a.e.) of the herbicide glyphosate (0, 720, 1,440, 2,160, 2,880, and 3,600 g ha-1) and a hoed control. African star grass is tolerant to the usually recommended doses of the herbicide (720 to 1,080 g ha-1 a.e.). Doses of glyphosate, ranging from 1,232 to 1,439 g ha-1 a.e. suppress the grass, avoid its competition with corn, and allow the recovery of the pasture after the corn harvest.
