Plant protection
Pest
Gall caterpillar
Young caterpillars bore into the apical portion of the shoot during rainy season and make tunnel. Due to this, apical regrowth is checked, side shoots develop below the gall and subsequent growth in following season is greatly hampered. Cutting off the infected apices and prophylactic spray of systemic insecticide like Dimethoate 0.03 percent will control the pest.
Bark eating cater pillar
Damages the stem and branches of grown up trees by eating the bark. The affected portion should be cleared and few drops of kerosene should be applied in holes to keep this in control.
Disease
Rust
Rust appears as circular reddish solitary or gregarious on leaves and also on fruits. Spray 0.2 per cent Mancozeb at an interval of 7 to 28 days during July to September.
Yield
The crop yields about 100 kg/tree annually.
