Management of Bacterial Blight Disease in Ginger Crop

In ginger, this disease is often seen during the rainy season, in which water soaked spots appear in the collar region of the pseudostem, which expands upwards and downwards.
The first characteristic symptom of this disease is a slight curling of the leaf margins of the lower leaves, which spreads upwards.
Yellowing first starts from the lowest leaves and gradually progresses to the upper leaves. At a later stage, the plant shows signs of severe yellowing and wilting.
The vascular tissues of the affected pseudostems show dark streaks. The affected pseudostem and rhizome when pressed gently extrudes milky ooze from the vascular strands.
For its management use Kasugamycin 5% + Copper Oxychloride 46% WP @ 300 gm/acre or Streptomycin Sulphate IP 90% W/W + Tetracycline Hydrochloride IP 10% W/W @ 24 gm /acre.
For biological control use Pseudomonas fluorescens 1 kg/acre.
