Tomato leaf roll is one of the two most serious diseases of tomatoes in the Top End. The other is bacterial wilt. Tomato leaf roll is particularly serious along coastal areas. Losses of up to 100% have been recorded and losses of 60% are quite common. In contrast to the 1970s and 1980s, the last several years up to and including 2001 were relatively free of tomato leaf roll. However, in 2002 there was a sharp increase in the reported cases of the disease attacking tomato plants, reaching the severe levels of the 1970s and 1980s. [more] |

Grapevine Leaf Rust is caused by the wind borne fungus, Phakopsora euvitis. The disease occurs in several countries in South East Asia and in other parts of the world. Australia was free of the disease until 2001 when it was detected in the Darwin area. The rust is a potential threat to the Australian grapevine industries and is currently the target of an eradication campaign [more]. |
