Herbicide tolerance and water use efficiency in forest species used in degraded areas recovery programs

The use of tree species in recovery areas is a sustainable practice in many Brazilian regions. However, a major challenge is to manage invasive species and contain the herbicide residues applied in areas for recovery. Amid all the concerns about water crises, employing species with a better use of w...

The total dose proposed for each product was twice the average recommended dose (2.5 kg ha-1, 2.0 L ha-1 and 0.806 kg ha-1, respectively, for atrazine, clomazone and 2,4-D), divided into six ten-day intervals each.
