Effect of plant-parasitic nematodes on initial growth of sugarcane in Tanegashima Island was examined by means of a pot experiment. Two sugarcane cultivars, NiF8 and Ni22, were grown in pots filled with two soils from sugarcane fields in Tanegashima treated with 0 g, 0.75 g per pot (corresponding to 30 g/m2), or 3.75 g per pot (corresponding to 150 g/m2) of 1.5% fosthiazate granules. Both fosthiazate treatment and cultivar difference influenced sugarcane culm height, shoot dry weight, and root dry weight significantly by ANOVA. In one soil with a high initial density of lesion nematodes, there was a significant difference in growth of Ni22 among fosthiazate treatments, whereas the difference was small and not significant for NiF8. These results suggested that plant parasitic nematodes affect the initial growth of sugarcane in Tanegashima Island soil, and the effect was different between two cultivars.
