Abstract
In Kerala, Radopholus similis is considered as on important limiting factor in the establishment of coconut seedlings. For its control, it is important to know about its ability to survive in soil in the absence of host. It survived in air dried soil, with a moisture range of 0.1 to 1.0 per cent, for a period of three months. Under moist conditions (irrigated regularly) active population could be recovered up to 15 months. The infested coconut roots did not harbour active population after a period of one month in dry soil and two months in moist soil; but the population that had come out from the severed roots survived under field conditions in moist soil for six months, whereas it survived for only one month in dry soil.
