Ampersand Adjuvant Can Reduce Organic Herbicide Use Rates by Half Without Sacrificing Performance

Attune Agriculture, a leader in combining agriculture and food science to create products using hydrocolloid technology, has announced that its OMRI listed adjuvant, Ampersand, can reduce the use rate of organic herbicides by 50%, while maintaining the same level of performance as high use rates.


Ampersand is a unique adjuvant formulated with hydrocolloids that provides superior deposition, adhesion, evaporation control and wash off resistance. The result is less drift, more spray to the plant, more product on the plant, and more active ingredient in the plant.

Trials with three leading organic herbicides demonstrated that the addition of Ampersand is able to significantly boost the performance of costly active ingredients.  Comparison plots were sprayed with tank mixes containing Suppress at 6% alone and again with a significantly reduced rate of Suppress at 3% plus Ampersand.  Both plots showed comparable results in weed control.  Trials performed with Homeplate had remarkable results as well.  Homeplate at a high use rate (@ 6%) compared to a low use rate (@ 3%) with the addition of Ampersand had the same level of control.  In both trials, Ampersand was able to increase the level of performance of the 3% use rate to match the level of control at the 6% use rate.
