Screening of castor cultivars against capsule borer, Dichocrocis puntiferalis guin

An experiment to screen 10 different castor cultivars against Dichocrocis punctiferalis was conducted during kharif season of 2011–12. Studies on screening revealed that the genotypes GC-2 was found less susceptible to castor capsule borer with less no. of larvae per plant (1.63), shoot incidence (2.02 per cent) and per cent capsule damage (3.93 per cent). The genotype GAUC-1, GCH-4, GC-3, GCH-5, GCH-2 and GAUCH-1 were recorded less per cent shoot incidence, capsule damage by castor capsule borer. While, the genotype GAUC-1, GCH-4, GC-3 and GCH- 5 recorded the minimum per cent capsule damage.
