Consider Argentine stem weevil in pasture/crop establishment

Region: Northland, Auckland, Bay of Plenty, Waikato, Gisborne, Hawkes Bay, Taranaki, Manawatu-Whanganui, Wellington.

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.
