LI 700 is a non-ionic, soy-oil based, penetrating surfactant that reduces off-target spray drift and reduces spray water pH, while enhancing performance and reliability of foliar products.

Not only is LI 700 a penetrating surfactant, it also acts as a pH adjuster / acidifer, drift reducing agent, and deposition and harvest aid. It can be used effectively with many crop protection products to provide the highest level of performance. While most surfactants are able to perform one or two functions to enhance pesticides, LI 700 is a complete surfactant solution designed for a wide range of target chemistries, including weak acid herbicides (eg. all glyphosate formulations, 2,4-D, dicamba, etc.), insecticides, fungicides, and defoliants.

Surfactant: Spray droplet deposition, adhesion, and coverage of spray material on leaf surfaces are improved via surfactant properties. The effectiveness of systemic herbicides, insecticides, fungicides, miticides, PGR's, and foliar-applied nutrients are maximized via penetrating properties. LI 700 with Leci-Tech technology provides quicker uptake with no impact on crop safety in order to maximize pesticide and nutritional product performance. The unique Leci-Tech technology reduces product breakdown in the spray tank and improves rainfastness, resulting in superior product performance. If you want optimal economic response from herbicides, fungicides, insecticides, and foliar plant nutrients, use LI 700 as a penetrating surfactant.

pH Adjuster / Acidifier: LI 700 has a unique formulation that acidifies the spray solution, effectively lowering the pH level. With its acidification properties, the spray solution pH is reduced, preventing pesticide degradation and maximizing performance. This allows you to adjust the pH of your water to ensure your pesticide investment is not wasted. Many pesticides undergo a chemical reaction in the presence of alkaline water that reduces their effectiveness. This pH Adjuster is a buffering-acidifying agent that changes the pH of a spray solution and keeps it there for good.

Drift: LI 700 improves deposition and spray coverage, while reducing drift potential by producing a more uniform spray pattern and reducing the incidence of small droplets that tend to drift more readily. With advances in herbicide tolerant crops and pre-seed burn down, spray drift from glyphosate products has become an issue. LI 700 helps growers overcome this issue by reducing the number of fine droplets in the spray pattern and producing more "performance-sized" droplets that don’t drift. It is the only penetrating surfactant labelled for lowering potential for off-target spray. When added to spray solution, the average droplet size is increased, resulting in more uniform droplet size, increasing on-target application. Also, the velocity of spray droplets is increased by 40% compared to using water as the sole herbicide carrier. Increased velocity means water droplets have more momentum and are less likely to drift.

Mixing Order: LI 700 should be added to the tank last unless you are utilizing as a pH adjuster.

Do not reuse containers. Container is recyclable and is to be disposed of at a container collection site. Before taking container to the collection site, triple or pressure-rinse the empty container, adding the rinsate to the spray tank. Make the empty container unsuitable for further use. If there is no container collection site in your area, dispose of in accordance with provincial requirements. For information on disposal of unused, unwanted product, contact the manufacturer or the provincial regulatory agency. Do not contaminate water, food, or feed by storage or disposal.
