Argentine stem weevil is building up in the North Island and will need to be considered in pasture and crop establishment. Insecticide coated seed may be a viable control option and insecticide application can provide temporary relief from this pest and allow seedlings to establish. Argentine stem weevil is a significant threat to seedling grasses, even those infected with endophyte, cereals and maize crops. See DairyNZ Pasture Renewal Guide for a guide to endophyte selection.
