Black rot or Koleroga
Centering and handling of the bushes should be done prior to the onset of South-West monsoon. Remove affected twigs. Spray 1% of Bordeaux mixture during break in monsoon.

Collar rot
Treat seeds with Carbendazim 1 g/kg or Carboxin 0.7 g/kg.  Maintain filtered shade in nursery.  Drench nursery beds with Mancozeb or Captan 0.5 g/lit before sowing.

Brown eye spot
Brown eye spot can be controlled by spraying Captan or Mancozeb or Ferbam 2 g/lit or Carbendazim 0.5 g/lit during September.

Black root rot
Dig out and burn infected bushes. Dig a trench 30 cm deep around affected spot along with a ring of healthy bushes. Prune the healthy bushes within and outside the trench to allow sunlight.  Keep the trench free from fallen leaves. Do not replant for 18 months.

Harvest
Harvest starts during November and harvesting extends up to February.  Coffee fruits should be harvested as and when they become ripe.  Coffee is just ripe when on gently squeezing the fruits the beans inside come out easily.  Unripe fruits should be scrupulously sorted out before using the fruits for pulping.  They may be dried separately as cherry.

Fly picking: Small scale picking of ripe berries during October to February

Main picking: Well formed and ripened berries are harvested during December. Bulks of the yields are obtained from this picking.

Stripping: Picking of all the berries left irrespective of ripening.

Cleanings: This is collection of fruits that have been dropped during harvesting.
Unripe fruits should be scrupulously sorted out before using the fruits for pulping. They may be dried separately as cherry.
