We determined the efficacy of an nC27 petroleum spray oil (PSO) (Caltex Canopy®) against Helicoverpa spp. on commercial cotton crops. Cotton plants treated with 1 – 5% (v/v) of the nC27 PSO were better at deterring oviposition by Helicoverpa spp.

Adoption of within-field monocultures of annual crops in modern farming systems is known to discriminate against and reduce the activity of predatory insects. In Australia, cotton fields are strictly monoculture and lack ecological diversity which co
