Blue Mould Rot:

Disease ID : ToPDB_DD043

Summary :

Introduction : Blue mold rot is a fungal plant disease and important pre and post harvest disease, often penetrates the pericarp directly if growing from a food base such as plant debris or decaying petals.

Pathogen cause : Didymella lycopersici

Host distribution : Lycopersicon esculentum, Abelmoschus esculentus, Carya illinoensis, Colocasia esculenta

Sign and Symptoms:

Lesions are blue slightly water soaked near the stem end of the tomato. A blue mold forms at breaks in the skin surface or sparsely over the fruit surface.

Etiology:

The disease grows rapidly at 18 , 24 °C and continues even at 0 °C. Tomatoes held in cold storage for a prolonged period are at risk to blue mold rot, especially damaged fruit.

Gene(s) Resposible for Disease:

Gene ID :

Control:

Biocontrol: Bacterium Pseudomonas fluorescens WCS365 on the Composition of Organic Acids and Sugars in Tomato Root Exudate

Chemical control: fungicides- Prochloraz, Bromuconazol, Benomyl, Carbendazim, Fludiozonil
