This poster summarises the results of field trials (conducted under project VG01096) aimed at evaluating DADS (90% diallyl disulphie, Alli-Up’) as part of an integrated strategy for the sustainable control of onion white rot. DADS is a germination stimulant of sclerotia (the “resting spores” of Sclerotinia) and it is applied as a soil treatment before planting. The aim is to reduce the population of sclerotia in the soil. It was found that when use of DADS was combined with correctly applied and timed fungicide treatments or early season applications of a biocontrol agent, effective and sustainable control of white rot was achieved. It was intended that efficacy and application data collected by this research would be used to support registration of DADS in Australia.
