Abstract
An epidemic outbreak of lac insect Kerria lacca on sandal and its host trees at Gottipura and Nallal in Hoskote range (Karnataka) is reported. It is found that 24.5% of the trees were heavily affected (9.3% of which are dead), 25.5% had medium attack and 50% were completely free. To control the lac infestation, the affected branches were lopped off, burnt and an insecticide viz., Ekalux 20AF 0.5% mixed with 0.05% sticker was sprayed on the tree. The treated trees were watered. This has completely controlled the lac infestation on sandal. A second spray with any insecticides, like Rogor 30 EC, Fenvalerate, Cypermethrin or Dimethoate, may be sprayed after formation of new flush of leaves, to check further secondary infection.
