Kovar Flair NS® 

Use of a nonionic surfactant (NIS) like Kovar Flair NS is the most common way performance of most pesticides can be improved. By lowering the surface tension of the water droplet nonionic surfactants increase the amount of leave surface that comes into contact with the active of the pesticide thereby increasing penetration into the leaf especially with water soluble and systemic herbicides. Kovair Flair NS is a premium NIS that contains 90% active ingredient and has defoaming properties. Combined with its ability to works well in cold water situations and tank-mixability with a multitude of products makes Kovar Flair NS a preferred NIS choice.
