Abstract
Lepidopterous larval populations on processed cabbage, from head initiation until harvest, were compared with percent cull material (a direct function of grade) in 27 commercial fields in New York over a 2-year period. Although larval populations varied considerably between fields and between years, no significant correlation (r2 = 0.004, 25 df) between percent cull material and larval populations existed. The majority of cull material was green tissue which would have been removed regardless of lepidopterous injury. The rationale for strict control of lepidoptera on processing cabbage, from head initiation until harvest, was not found to be cost effective.This publication has 1 reference indexed in Scilit:
