Amendment of soil with gypsum or lime and its effect on the incidence of cavity spot disease of carrots caused by Pythium coloratum

Abstract
Cavity spot is a major soil-borne disease of carrots worldwide. It reduces the quality or carrots so that they become unmarketable resulting in substantial economic losses to the grower. Cavity spot disease of carrots is caused by different species of the genus Pythium. In WesternAustralia, P. coloratum and P. sulcatum are the causal agents of cavity spot disease with P. coloratum causing more severe cavity spot than P. sulcatum. The application of lime has been reported to reduce the incidence and severity of cavity spot disease in Western Australia. The objectives of this investigation were to study the effect of lime or gypsum on the development of cavity spot disease of carrots in soil artificially infested with P. coloratum and attempt to discriminate between the effects of pH and calcium on disease development.
