Abstract
Among the various pests that attack pomegranate, anar butterfly, Deudorix (=Virachola) isocrates Fab., has assumed a major status limiting the cultivation of this crop in and around Panchmahal district of Gujarat, India.
An attempt was therefore made to study varietal reaction, extent of damage and management of borer in commercially grown cultivars of pomegranate.
In all, there were five cultivars viz., Ganesh, Mridula, Jyoti, Ruby and Jalore seedless which were replicated four times.
There were four plants in each replication.
The crop chosen for the experiment was the late Hasta and early Ambe bahar crop.
In order to retain the crop, need based irrigation was given at regular interval.
Bagging was resorted for management of borer.
Observations on varietal reaction to borer revealed that all cultivars were found to be equally susceptible to borer attack.
The incidence ranged between 35.0% in Jalore seedless to 42.0% in Ganesh. Gradually, it increased from 50.0 to 60.0% in the second week of March.
The situation was however further deteriorated and almost 80-90% fruits were found to be damaged by borer in unprotected plot.
The experi¬ment on bagging of fruits showed significant reduction on percentage damaged fruit and the extent of damage was observed to be below 10.0% in almost all cultivars as against 90.0% in open fruits.
