Abstract	Leiva L., J. N. 2008. Evaluation of Glyphosate, Paraquat and Glufosinate in weed management in Jatropha curcas crop, Choluteca, Honduras. Graduation project of the engineer program in Agricultural Sciences and Production, Escuela Agricola Panamericana, Zamorano, Honduras. 14 p. Densities in Jatropha curcas crop are low 1736 plant per hectare (3.6 m × 1.6 m), allowing in the first three to four years between plants enough space for weed growth. Glyphosate, Paraquat and Glufosinate were evaluated after 28 days of herbicides application. The objective was to determinate efficiency in weed control, crop damage and economic aspects related to the applications. The three herbicides and a control without herbicide application were the treatments with four repetitions each plot of 41.6 m (5 m × 8.2 m). Rates used were 3 L/ha of Paraquat and Glufosinate and 4 L/ha of Glyphosate, according to product indications. After 14 days post applications Glyphosate and Paraquat did not have significant difference (P=<0.05) with 78 and 84% of weed control, respectively. After 28 days, Paraquat and Glufosinate did not differ, and Glyphosate had 97% weed control. Glufosinate had its best performance 7 days after application with 60% weed control, decreasing these after and not recommended its application in this system. Paraquat controlled 89 and 84% weeds 7 and 14 days after application, post evaluations showed a decreasing control. Glyphosate did not damage the crop, otherwise Paraquat caused an average necrosis of 5% in approximately four leafs per plant. Cost applications were US $ 169, 200 y 354 for Paraquat, Glyphosate and Glufosinate, respectively.
