POPULATION DYNAMICS AND CONTROL OF PLANT PARASITIC NEMATODES ON BANANA IN THE SULTANATE OF OMAN

A. Mani, M. S. Al Hinai

Abstract


The population dynamics of Helicotylenchus multicinctus, Meloidogyne incognita and Tylenchorhynchus coffeae on banana was studied at Barka in the Batinah region of Oman from October, 1992 to September, 1995. Populations of each nematode species reached their highest densities during February-April, declined sharply during the summer months of May, June and July and then builtup again form August onwards. The efficacy of three granular nematicides was evaluated at the rate of 40 g/clump under field conditions against the three species infecting banana. It was observed that ethoprophos was the most effective nematicide in reducing nematode populations followed by fenamiphos and oxamyl.
