Bacterial wilt of ginger in Queensland

Abstract

Bacterial wilt (Pseudomonas solanacearum) of ginger was recorded in Queensland for the first time, Two types of wilt caused by biotypes 3 and 4 could be distinguished. Seven weeds commonly found in ginger plantings were found infected with biotype 3.
The pathogenicity of biotype 4 to a number of hosts was determined and its reaction on ginger was compared with that of biotype 3 and also biotype 2 isolated from potato.
