Anthracnose : It is a serious disease on leaves and young shoots in rainy season and on fruits after harvest

The disease results in leaf spot, blossom blight, wither tip, twig blight and fruit rot symptoms. Young leaves when infected wither and dry up.  At times when only the edges of the leaves are affected, their margins darken, dry up and may fall out, giving the leaf a ragged appearance. . .

Powdery mildew : It is a serious disease, which attacks the young leaves as well as the panicles.

Wefts of white mycelium on leaves, inflorescences and fruit lets develop. Later on the whole surface of the infected parts are covered with a powdery coating. The affected fruit let’s do not grow in size and may drop before attaining pea size. . . .

Stem end rot : It attacks the fruits. Epicarp turns dark around the base of the pedicel in the initial stage

Subsequently the affected area enlarges to form a circular black patch which extends rapidly under humid atmosphere and turns the whole fruit completely black within two or three days. The pulp of the diseased fruits becomes brown and somewhat soft. . .

Blossom blight : This disease causes heavy damage to the panicles

The blossom appear blighted from the bud swelling stage and whole blossom turn into the black thick mass of the tissue. Panicles do not develop fully and result in heavy crop loss.. . .

Die Back : It attacks the plant; as a result the twigs dry off. Drying of twigs and branches followed by complete defoliation gives the tree an appearance of scorching by fire

Discoloration and darkening of the bark occurs some distance from the tip of the twigs. The dark area advances and young green leaves start withering first at the base and then extending outwards along the vein. The affected leaves turn brown and its margins roll upward. . . .
