The bacterial biocontrol agent Pasteuria penetrans can help control root-knot nematode on sugarcane [Full subscriber]

Abstract Root-knot nematode (Meloidogyne javanica) is one of the most damaging pests of sugarcane, often causing heavy losses in coarse-textured sandy soils. The bacterial parasite Pasteuria penetrans is a potentially useful biocontrol agent and in a 2015–16 survey it was found at relatively high levels in three of the 126 sugarcane fields surveyed. Soil was collected from one of the heavily-infested fields and a pot experiment established to compare root-knot nematode multiplication in naturally-infested soil and in soil where the endospores of P. penetrans had been killed by autoclaving. After 37 weeks, the root-knot nematode population was very high in…
