Colorants for Weed Spraying From: Cindy & Lou Lunte (cllunte(at)cyberhighway.net) We have had great success using Hi-light by Becker-Underwood as a dye when spraying. It is bright blue at first but gradually fades away after about 2 days. It makes it much easier to make sure you are hitting exactly what you want - I wouldn't even think of spraying without it now. As a extra benefit it also lets you know if you have any drips or get any of the chemical on yourself or your clothes - a big plus in my view. Cindy Lunte Conservation Projects Specialist The Nature Conservancy of Idaho --------------------------------------- 2. Colorants in Garlon 4 From: Bill Kleiman (nachusa(at)essex1.com) For coloring Garlon 4 you want petroleum based herbicide colorants. Blazon, I believe, is for water based herbicide. "Bas-Oil" Red Dye is available at Forestry Suppliers and likely Ben Meadows. Very red and lasts for weeks. Works great. Very concentrated. One pint is $22 and would likely color 20 to 30 gallons of oil based herbicide. Nachusa Grasslands, The Nature Conservancy 2055 Lowden Rd., Franklin Grove, IL 61031 815-456-2340.
