Description:

• Leaf spot mainly occurs in moist weather with intermittent showers, particularly when the relative humidity is high.

Damage Symptoms:

•  Small, round to irregular spots with a grey centre and dark margin on leaves.
•  Spots usually start on lower leaves and gradually advance upwards.
•  In the later stages of infection, spots coalesce, leading to large necrotic areas.
•  In severe infection, complete defoliation of affected leaves occurs, leading to reduced photosynthesis and affecting the size and quality of fruits.

Preventive Measures:

•  Practice crop rotation.
•  Remove and destroy infected plant debris.

Control Measures:

•  Spray Zineb @ 0.2% or Mancozeb @ 0.2%.
