Abstract
In experiments conducted in Darwin, Australia, temperatures generated during November at 25 cm depth in nursery potting mix by solarisation reached maximum values of 51°C and 44.6°C under a double and single layer of clear plastic mulch, respectively. The lowest temperatures were 41.3° and 38.1°C in July under the double and single layer of clear plastic mulch, respectively. Acyclic pattern of temperatures occurs over a 12 month period, following closely the global radiation figures. Three soilborne plant pathogens, Pythium myriotylum, Phytophthora nicotianae var. nicotianae and Sclerotium rolfsii were eliminated under a double layer of plastic within 2–8 days during the spring, summer and autumn experiments while it took 4–20 days at the same time of the year to eliminate the same pathogens using a single layer of plastic.
