Currently there are NO insecticide tank mixes registered on the Roundup brand agricultural herbicide labels. However, Monsanto Canada will support a tank mix with Decis®, Matador® and Sevin® insecticides for post-emergent application in Roundup Ready® Canola. Mix and spray the Roundup brand agricultural herbicide and insecticide combination immediately! Do not let the tank mix sit in the tank as the products may form a precipitate or settle out in the tank.
*As with all tank mixes, ensure you start with a generous amount of water before adding products.
