Description

• Moist weather with humidity above 80% and moderate temperatures are favourable conditions for the occurrence of this disease.

Damage Symptoms

• Water-soaked lesions with faded green patches appear on the leaves.
• Infections spread rapidly to the entire leaf and petiole. Later, the leaves become blighted and dry.
• Dark brown to black lesions occur on the stem, resulting in wilting and weakening of the plant structure.
• The disease manifests on tomato fruits as dark, sunken spots with a firm, leathery texture, making the fruits unmarketable.
• In severe infections, the whole plant dies.

Preventive Measures

• Maintain proper spacing between plants.

Control Measures

• Spray mancozeb, zineb, or metalaxyl + mancozeb.
