Farming Irrigation :

• It requires life saving watering in the first year during winter and summer.
• Irrigation improves the plant growth, flowering and fruiting in citrus.
• It also reduces the fruit crops and increases the fruit size.
• Under unirrigated condition chances of damage to spring blossom is high and the next crop maturing in October-November may be heavier.

Major pests are indicated below:

• Trioza obsoleta feeds on the sap and forms rough reddish-yellow galls on the leaves.
• Among the defoliators are Euthalia laudabilis, E. nais, Lamida carbonifera and Miresa albipunctata.
• The larvae of Plocaederus ferrugineus bore between the bark and the sapwood.
• The fungus Stereum lobatum causes white spongy rot in felled timber while Cercospora kaki causes leaf spot.
