Abstract	This study was conducted at the Experimental Nursery of the Ornamental Horticulture Department, Faculty of Agriculture, Cairo University during the two successive seasons of 2009/2010 and 2010/2011. This work aimed to investigate the response of paspalum (Paspalum vaginatum, Swartz cv. Salam) grown under different shade levels to foliar application of different concentrations of paclobutrazol and trinexapac-ethyl (TE). The turfgrass was covered with shade cloth of different light permeability levels providing shading levels of 42%, 63% and 70% of natural light. In addition, full sunlight (unshade) was used as a control. Plants grown under different shade levels treatments were sprayed monthly with either paclobutrazol (at 750 or 1500 ppm) or TE (at 200 or 400 ppm). Control plants were sprayed with tap water.It can be concluded that Paspalum vaginatum plants can be grown under shade level up to 42% with no significant reduction in growth. However, if shade level exceeds 42% (up to 70%) paclobutrazol at 1500 ppm or TE at 400 ppm can be used monthly as a foliar application to overcome the adverse effects of shade.
