Blue mould (Peronospora tabacina Adam) has been a major disease of flue cured tobacco in Queensland since the crop was first grown a century ago. Two strains of the disease are of economical significance. The APT 1 strain is prevalent in north Queensland, and can be controlled by the use of resistant varieties the first of which was bred and released by CSIRO in 1969. These varieties have little tolerance to the second strain APT 2 which is prevalent in south-east Queensland. Extensive efforts by CSIRO prior to 1975 and by Queensland Dept. of Primary Industries since have achieved field resistance to this strain. Since 1975 Beerwah Tobacco Field Staton has been utilised as the venue for all screening of breeding material for resistance to APT 2 strain blue mould. The integrated use of fungicides in combination with APT 2 field resistant breeding lines has been assessed and a backcross programme to improve yield and quality of blue mould field resistant lines has been conducted. The field Station has also been used for the ongoing district testing of advanced lines involving yield and quality assessment plus cured leaf chemical analysis.
