CERTAIN is an exceptional type of alcoxylated alcohol which lowers dynamic surface tension of the sprayliquid. The extremely fast way in which CERTAIN lowers surface tension makes sure that bouncing of droplets, even on the most hydrophopic of leafsurfaces and regardless of dropletsize, is completely suppressed.

Most surfactants reduce the surface tension of water slowly, so when spraying larger droplets, when a droplet reaches the leaf surface, the surface tension is still not as low as it could be and the droplet can still not adhere to the leaf properly. CERTAIN lowers the surface tension of water almost as soon as it comes out of the spray nozzle.

This makes sure that your spray actually stays on the leaf. These super-wetting characteristics of CERTAIN result in maximum amount of pesticide on the crop.
