A common question is whether a detergent soap will suffice as a <br /> surfactant or not. The best answer is to use the recommended <br /> surfactant designed to enhance the activity of a specific herbicide. <br /> When a user is investing time and money into a weed management <br /> project, why jeopardize success over such a minor cost. <br /> Surfactants recommended for the herbicides listed in this guide: <br /> • COC - Crop oil concentrate is a petroleum oil based product, <br /> typically applied at a rate of 1 quart/acre, recommended for <br /> use with imazapyr and triclopyr on cut-stump treatments. <br /> • MSO -Methylated seed oil is a plant oil derivative, typically <br /> applied at a rate of 1 quart/acre, for use with imazapic and <br /> quinclorac. Often used with other herbicides when applied <br /> over weed species with very waxy or hairy leaves such as <br /> common mullein or Dalmatian toadflax. <br /> • NIS -Nonionic surfactant is an organic compound usually <br /> mixed in at 0.25 —0.50 % volume per volume ratio for <br /> example .25% v/v= 1 oz per 3 gal, for use with all other <br /> herbicides listed in this guide. This surfactant is absolutely <br /> essential for chlorsulfuron, metsulfuron methyl, and <br /> rimsulfuron to be effective. <br /> GUP—General Use Pesticide. Are products which are available to <br /> the general public. All herbicides listed in this guide are general <br /> use unless otherwise specified. <br /> MSDS —Material Safety Data Sheet. A technical bulletin that <br /> supplements information found on the product label. This bulletin <br /> provides detailed descriptions of a product's physical properties <br /> and toxicity, and provides users and emergency personnel with the <br /> proper procedures for handling and working with that substance. <br /> Pesticide Label—A legal document located on the pesticide <br /> container that provides information concerning the safe and <br /> effective use of the pesticide. It is a violation of federal pesticide <br /> laws to use any pesticide in a manner inconsistent with its labeling. <br />
