- Observation The distribution of the cotton pest Meloidogyne acronea in southern Malawi was restricted by soil-type.
- Observation In vitro, M. acronea survived dry conditions as dormant eggs within egg masses at a relative humidity of 97.77 but not at 96 or 100% in the absence of a host.
- Observation The two soils at permanent wilting point differed significantly in relative humidity and rate of water infiltration.
- Observation Shrinkage on drying occurred in the vertisol but not in the alluvium.
- Observation The vertisol had a relative humidity of less than 96% at permanent wilting point.
- Mechanism Moisture loss, shrinkage and cracking of the vertisol in the dry season were asserted to kill all M. acronea eggs and so limit its distribution to alluvial soils.
