Abstract:Seventy-two stratified random 929-cm2 soil samples were sufficient to estimate density of Euxoa ochrogaster (Guenée) in commercial-sized peppermint fields of 3 different age classes. Larvae were contagiously dispersed in most fields sampled, but when the density was <0.50/929 cm2, dispersion appeared random. Sequential sampling plans were developed for newly planted fields <1 yr old (class I) and declining fields ≥ 6 yr old (class III). A plan could not be developed for class II fields (2–5 yr old) because cutworm densities were too low to determine the ElL in this study. These plans will provide growers with procedures to determine whether or not control is justified for redbacked cutworm in 2 different-aged peppermint fields.
