Alternative symphyla control measures and their effect on plant cane establishment

Abstract

In some areas of the Herbert Valley, the 'root-pitting' damage caused by symphyla to young cane roots is severe enough to produce noticeable reductions in growth and emergence of young plant cane. Chlorpyrifos at 2 1/ha of 50% product sprayed in the drill at planting is the currently recommended control. These trials confirmed that the recommended control was still effective. A difference in susceptibility to damage was also observed. Mocap (100 g/kg ethoprophos) at 20 kg/ha applied in the drill at planting gave a similar level of control to that of the present recommendation.In some areas of the Herbert Valley, the 'root-pitting' damage caused by symphyla to young cane roots is severe enough to produce noticeable reductions in growth and emergence of young plant cane.
