Managing Nematodes In Citrus Orchards

Abstract

Citrus trees are damaged by several nematode parasites, all but one of which are of limited distribution worldwide. The most economically important species is Tylenchulus semipenetrans by virtue of its presence in all citrus producing regions. The nematode is noteworthy for its intimate association with citrus and the ability of trees to support very large populations before damage becomes evident. Several of the remaining species are among the most damaging parasites in the citrus rhizosphere. This chapter reviews the biology, ecology and economic importance of these nematodes from the standpoint of pest management.
