South Florida Water Management District PDS B-14 Enhanced Herbicide Reduction Test

Leap2 Solutions innovative adjuvant PDS B-14 (Polymer Delivery System) for the enhancement of herbicides (triclopyr and imazapyr) aerial applications to: Woody shrubs and mixed grasses.

Date of Applications: March 30, 2011 and March 31, 2011 Photographs taken: May 17, 2011

Seven weeks post application, the woody shrubs not sprayed with a PDS B-14 enhanced mixture have caught up to the woody shrubs sprayed with the PDS B-14 enhanced mixtures( 30% reduced herbicide volume, 15% reduced herbicide volume, full strength) in terms of the decay, loss of moisture and death exhibited by the woody shrubs.

The woody shrubs sprayed with PDS B-14 enhanced mixtures demonstrated faster reactions to the applied herbicides and at significant herbicide reductions of 30% and 15%, when compared to the plants sprayed with the customary herbicide mixture without any PDS B-14.

What this demonstrates is that by utilizing PDS B-14, an applicator is provided faster response to the applied herbicide, a quicker kill, and provides a cost-savings as well, by using 15-30% less herbicide in the application.

Imazapyr was used in the herbicide solution to kill the grassy plants, which normally takes 2-5 months to start to see its effect on the plants.

The mixed grasses are showing yellowing, and degradation due to the utilization of PDS B-14 in the various mixtures. (30% reduced herbicide volume, 15% reduced herbicide volume, full strength herbicide volume) This efficiency and speed of action that we observed in the woody shrubs and now in the mixed grasses can be attributed to the innovative crosslink polymers within PDS B-14. The yellowing and degradation of the mixed grasses is even more evident with each passing week, and they continue to degrade as evidenced by these seventh week photographs.
