A research to determine the effectiveness of lamtoro leaf extract on the growth of weeds in young tea plan­tation was carried out in Pasir Sarongge Experimental Garden and Plant Pro­tec­tion Laboratory RITC Gambung from June to December 2009. Researches on the effective­ness of lamtoro leaf extracts on the germination of weed’s seed, and on the growth of weeds in the field, were conducted. Lamtoro leaf extract treat­­ment at various concentrations tried, suppressed the germination of seeds of broad­leaf weeds (hareuga and babadotan) in the laboratory. In general, the germination supp­ression were increases with increasing the concentration of the extracts tested. Spraying of lamtoro leaf extract (Leucaena sp.) starting at concentration of 7.50% resul­ted better control effect and significantly different compared to controls. In addition, spraying treatment of lamtoro leaf extract could reduce the number of weed species.
