The objective was to establish a weed-free</p><p>zone on the ridge area to allow the placement of fertilizer</p><p>close to the root systems, thus avoiding competition between</p><p>the roots of the papaya and those of the groundcover. Four</p><p>herbicides were used (acetachlor, pendimethaline, oxyfluorfen</p><p>and glyphosate) to asses their control of cyperous, broadleaf</p><p>and grass weeds. Possible damage to papaya plants due to the</p><p>effect of the herbicides was also monitored as well and their</p><p>response in terms of growth and yield. Glyphosate was</p><p>efficient for gramineous weed control but not against</p><p>broadleaves. Very good control for all weed types was</p><p>obtained during the 90 day post-transplant period with the</p><p>oxyfluorfen + pendimethaline and acetachlor treatments. The</p><p>first two herbicides affected papaya plants slightly when they</p><p>were applied 10 days after transplant. Acetachlor didn’t cause</p><p>any damage to the papaya. There were no differences among</p><p>the treatments in regard to growth and yield.</p>}, number={2}, journal={Agronomía Mesoamericana}, author={Bogantes-Arias, Antonio and Mora, Eric}, year={2004}, month={Aug.}, pages={193–199} }
