Abstract/Contents:"The reserach conducted was designed to minimize pesticide usage and lessen environmental impact by applying readily available ocean water to control weeds in turfgrasses. Sensitivity to ocean water of several tropical weeds including crabgrass (Digitaria spp.), mimosa (Mimosa pudica (L.) DC.), purple nutsedge (Cyperus rotundus L.), yellow nutsedge (Cyperus esculentus L.) and one-leaf clover (Alysicarpus vaginalis (L) DC) was evaluated. Concurrently, the salinity tolerance of hybrid bermudagrass (Cynodon dactylon x C. transvaalensis Burtt-Davy), seashore paspalumgrass (Paspalum vaginatum Swartz.), zoysiagrass (Zoysia japonica), and St. Augustinegrass (Stenotaphrum secundatum) to ocean water was evaluated. Three different salinity levels (19 dS m-1, 37 dS m-1, and 55 dS m-1) and 2 salt-stress durations (3 and 6 days) were tested. Preliminary results indicate that mimosa showed severe yellowing within one day and complete necrosis after 3 days of watering at 55 dS m-1 and 37 dS m-1. Crabgrass was less sensitive however signs of pronounced necrosis were noticeable after 5 days. One leaf clover and both types of nutsedge were the most robust. No treatments severely injured seashore paspalumgrass or bermudagrass; in all instances, they recovered from the injuries. The preliminary results indicate that ocean water can be used as an alternative to herbicides in turfgrass management."
