Anthracnose of Lime

Symptoms

Lime anthracnose affects flowers, young leaves and fruits, and lesions range from small spots that can expand to cover large areas. Leaves and fruit often shed and twigs are killed, resulting in "withertip" symptoms. Foliar symptoms are visible as necrotic spots that may result in a shot-hole effect if the necrotic areas fall out. In severe infections the leaves and entire young shoots can become totally blighted and drop. In addition, shoot tips may die back and leaf deformation may occur. Infection of young fruit usually results in premature fruit drop. Late infections produce lesions that are often large and deep and accompanied by fruit distortion.
