About TopFilm

Adjuvants are tank additives that a grower or applicator uses to optimise pesticide applications. The old technology usually uses synthetic or petroleum based oils, which penetrate and seal the plant surface, causing injury to crops, and are used in huge volumes.

This new Technology features TopFilm™, an adjuvant made from natural patented grain materials called Biocar®, which are microsponges that absorb pesticides and other plant treatments and offer coating properties to protect the application and optimise pesticide delivery.  Biocar® is patented under US Patent # 5,888,500 and European Patent #PCT/US97/17605.

TopFilm™ is a suspo-emulsion (SE) of Biocar®  that absorbs the active ingredient during the tank mixing and deposits a natural film of microsponges that stick the treatment to the leaf surface, flower or fruit during spraying. The natural film dries within 10 - 30 minutes and enhances rain-fastness, completely stopping wash off of the product by rain or irrigation.  The layer of sponges absorb the pesticide and release it slowly into the plant increasing the efficacy of all treatments.


Approved Adjuvant List Number:  A0670

This dramatically different adjuvant is cereal based (not oil based) and can be mixed with any pesticide to improved rain-fastness and herbicide delivery, resulting in increased efficacy and less pesticide use. Reduced frequency of application saves you money while improving weed control or crop performance.
