Argentine stem weevil numbers increasing

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.
