Abstract : In the plant pathology section (29-30) it is noted that further attempts to eradicate black sigatoka [Mycosphaerella fijiensis var. difformis] disease of bananas in the Torres Strait region were abandoned; movement of bananas from this region to other parts of Australia is prohibited. Difficulties were encountered in controlling cucurbit powdery mildew [Sphaerotheca fuliginea] owing to the increasing incidence of fungicide-resistant strs. Solarization gave good control of Verticillium wilt of tomato but was ineffective against race 3 of Fusarium [oxysporum f.sp. lycopersici] which threatens tomato crops in the Bowen area. Phytophthora root rot of soyabean was recorded in the major growing areas of southern Qd.; anthracnose [Glomerella cingulata] was the major problem affecting Stylosanthes and zucchini yellow mosaic virus affected a range of cucurbits in SE Qd. Cotton bacterial blight [Xanthomonas campestris pv. malvacearum] was widespread in central and southern regions; citrus canker [X. campestris pv. citri] was found on West Indian limes and sweet orange on Thursday Island and infected trees destroyed; and the most serious disease of the expanding mango industry is bacterial black spot [X. campestris pv. mangiferaeindicae].
