Abstract
Sugarcane yield decline is a replant type disease limiting the yield of almost all sugarcane crops in Queensland.
In glasshouse experiments, root symptoms of yield declined (YD) were compared with those of apple replant disease (ARD) in apples.
Responses to soil pasteurisation and the application of the general fungicide mancozeb were compared.
Sugarcane yield decline symptoms included reduced secondary and tertiary root growth, reduction in root hairs, and surface browning of roots.
Similar symptoms were seen with ARD. Soil pasteurisation and mancozeb resulted in growth responses in plants growing in the YD soil only.
