Technical feasibility of the use of groundcover in papaya (Carica papaya L.) by means of the localized application of herbicides.
An essay was conducted toevaluate the feasibility of implementing the use of naturalgroundcover in papaya (Carica papaya L.) under a ridgeplanting system. The objective was to establish a weed-freezone on the ridge area to allow the placement of fertilizerclose to the root systems, thus avoiding competition betweenthe roots of the papaya and those of the groundcover. Fourherbicides were used (acetachlor, pendimethaline, oxyfluorfenand glyphosate) to asses their control of cyperous, broadleafand grass weeds. Possible damage to papaya plants due to theeffect of the herbicides was also monitored as well and theirresponse in terms of growth and yield. Glyphosate wasefficient for gramineous weed control but not againstbroadleaves. Very good control for all weed types wasobtained during the 90 day post-transplant period with theoxyfluorfen + pendimethaline and acetachlor treatments. Thefirst two herbicides affected papaya plants slightly when theywere applied 10 days after transplant. Acetachlor didn’t causeany damage to the papaya. There were no differences amongthe treatments in regard to growth and yield.
