I really like it with Fusion, Storm, Pounce and Sevin. Research by Don Penner shows that corn syrup can boost activity on grasses for Roundup, generic glyphosate, Liberty and Touchdown. There are no federal standards for adjuvants, and so far no regulations covering their sale. Virtually anyone can put a product in a jug and sell it as an adjuvant. Adjuvant manufacturers and the Chemical Producers and Distributors Association have been pushing for a self-policed regulatory system for adjuvants.
Suppliers generally acknowledge that there are ways for competitors to cut corners.
A manufacturer might also try to get by with using a cheaper emulsifier. That may result in a less stable tank mix and more risk of crop injury. With the seal of approval system, a manufacturer would have to demonstrate that its products meet certain quality standards. It would not certify how effective the product is, but would at least verify that it is manufactured properly. A new edition should be available in January, 2000.
