COMPARATIVE INCIDENCE OF PLUSIA ORICHALACEA FAB (PEA SEMILOOPER) ON SUNFLOWER CULTIVARS

Abstract

Cultivar GK 2002 registered minimum population (4.91) larvae/ 50 plant but it was not significantly different from that of PG 1080 Morden, SSH 6163, sunshine 399, SH 9986, CSF 292 and SH 3322 with larval population varing from 5.56 to 7.39. The maximum larva population was supported by each of PHS 4, MSFH 17, MSFH 8 and PAC 8699 (11.20 larval/ 50 plants) and the remaining cultivars were intermediate.
