Abstract

Asparagus (Asparagus officinalis) crops on eight Queensland properties were surveyed for the presence of asparagus rust (caused by Puccinia asparagi) phomopsis stem blight (caused by Phomopsis asparagi) and asparagus anthracnose (caused by Colletotrichum gloeosporioides) in November 2002 All properties surveyed had a low incidence of rust disease Most rust developed on plants two weeks after spear emergence No symptoms of phomopsis stem blight or anthracnose were found in the Mundubbera and Beerburrum regions Anthracnose was found only in Mareeba (northern Queensland) The incidence of phomopsis stem blight was found to be high on one property in the Warwick region Examination of diseased plants showed that the respective pathogens were associated with the symptoms Drought was a major problem for growers and we observed that crops with an appropriate fertiliser and irrigation regime showed increased plant growth and less disease Crops with irrigation alone also showed better growth and less disease than those without irrigation Our observations suggest that an appropriate irrigation and fertiliser regime that promotes plant growth and health will lessen the likelihood of infection by these diseases However more research is required to confirm this
