The responses of 20 species of ornamental palms and one cycad (Cycas revoluta) to two populations of the reniform nematode, Rotylenchulus reniformis, from southern Florida were studied in two greenhouse experiments conducted in 1989-1991 and 1991-92. Ornamental palms in pots were exposed to initial population densities of 400 and 1,500 R. reniformis/l00 cm(3) soil for 16 and 15 months, respecti...

Based on findings from studies conducted in the Philippines over a span of almost a decade, primarily by scientists at the Philippine National Crop Protection Center, crown-baiting (wherein bait containing anticoagulant is placed monthly in the crowns of some palms in a coconut plantation), holds the potential of providing highly economical protection from rat damage. The success of the method ...
