Краткое описание

In April 2018, Citrus canker was detected in two retail nurseries on species of West Indian lime in Darwin, Northern Territory. Tracing activities are underway. The variety of lime is a potted patio plant that is not found in commercial production. This detection is under eradication, and movement restrictions are in place. Citrus canker is absent from other Australian states and territories.

Citrus canker has previously been detected in Australia in the Northern Territory (1912, 1991 and 1993) and Queensland (1984 (Torres Strait) and 2004) with successful eradication of each occurrence.

Опасность

Citrus canker is a contagious disease caused by the bacteria Xanthomonas citri subsp. citri which can affect all citrus species and cultivars. The disease presents as lesions or cankers at infection sites and severely impacts fruit quality and yield. Premature fruit drop can occur, along with defoliation, twig dieback and general tree decline. In severe cases, it can lead to tree death.
