Zipper is our first product and one of the first of the new generation of adjuvants in the agricultural market. back in 1997 it was such an improvement on the adjuvants that were available then that it is still in use today and is still considered one of the best adjuvants on the market. Zipper is an organic modified trisiloxane super spreader. Just a tenth of a percent of Zipper added to water increases the surface of a droplet a hundred fold as opposed to just water. This super spreading effect ensures an enormously improved coverage of the leaf whereby hard to reach places are also effortlessly reached. Zipper can spread the spraying liquid so well that water soluble pesticides can directly enter the stomata of the leaf.

The super spreading effect of Zipper makes it useful for a lot of different types of pesticides. The super spreading effect makes sure more of the spray liquid sticks to and stays on the leaf, which is positive for all pesticide products, both contact and systemic. More product on the leaf and more surface interaction also means that systemic products are taken up by the plant more easily which increases the efficacy of these products significantly. When spraying contact fungicides you just want as much of the product on the leaf as possible which Zipper can help with. Some insects can hide under leaves or in between small spaces where normally a droplet of water can’t reach. Zippers super spreading effect makes sure that even those places can be reached with the spray liquid.

Because this high spreading effect is not always most useful, Zipper can also be used at much lower dosages such as 0.005%. These low dosages do provide a better deposition and retention of the spray liquid but do not spread as much which can reduce runoff when large amounts of water are being used or when pesticides are used which are prone to cause phytotoxicity. The lower dosage rates also keep the cost of adding an adjuvant low.

Zipper has been around for more than twenty years and although there are many new products on the market today, it is still the preferred adjuvant in a wide range of crops in both horticulture and arable farming and in combination with a wide range of insecticides, herbicides and fungicides.
