An old product has a new registration in the weed control industry. LI700 was first introduced to the Canadian market as a penetrating surfactant and a pH reducer.
Recently, the Pest Management Regulatory Agency has approved LI700 as a deposition aid and drift reduction agent for use with glyphosate in Canada.
With advances in herbicide tolerant crops and pre-seed burn down, spray drift of glyphosate has become an issue. According to Garth Render, marketing manager with United Agri Products in Winnipeg, this new registration will allow growers to use LI700 to lessen the risk of spray drift by modifying the spray droplet size and reducing the number of small droplets that are prone to miss the target.

LI700’s formulation reduces the number of fine droplets without increasing the number of large droplets in the spray pattern. These large droplets tend to bounce or slide off the target plant and onto the soil surface. By increasing the number of droplets in the medium size range, the risk of spray drift is reduced and more herbicide is deposited on the leaf surface to control the targeted weeds.
“LI700 is a unique product that improves the performance of many crop protection products. By acidifying the spray solution, helping to deliver the spray to the target, spreading the spray on the leaf and assisting certain pesticides to penetrate the plant’s leaf surface, LI700 improves the performance of the product and reduces the risk of off target drift,” Render said. “Now growers can choose any glyphosate brand they wish, add the LI700 and be confident their product will perform in a variety of conditions that adversely affect product performance.”
