RATIONAL NEMATODE MANAGEMENT PRACTICES FOR THE AUSTRALIAN PINEAPPLE INDUSTRY

G.R. Stirling, A. Nikulin
In the absence of nematicide treatment, there were differences between pineapple (Ananus comosus L. Merr) fields in south-east Queensland in the extent to which root-knot nematode increased on newly planted crops. In some fields, nematodes were readily detectable 9–15 months after planting whereas in others, nematodes were not observed at 15 months. Nematicide experiments in twelve fields showed that increases in ratoon crop yield following application of ethylene dibromide (EDB) or fenamiphos were related to the population density of root-knot nematodes. Significant increases in yield were never obtained at sites where the nematode was not detectable at 15 months. The results suggested that some pineapple growers were needlessly applying nematicides and that nematode diagnostic services should be established to provide growers with rational advice on their nematode management programs.
