Test Results :: Rice

Since 2005, 28 seperate trials have been done in several countries around the world for the efficacy on several soil types and climate differences using different concentrations of our foliar spray (1,2 and 4 ml/L) and the frequency of sprays.

The results show healthier plants, more tillers, lower infection rate and increases in grain yield between 10% – 50%.

Within table 1 are the results for all trials with 4 sprays with a concentration of 4 ml/L. Our results have also shown that the foliar sprays induce a significant reduction of pesticides (from 35% – 100%) without losing any efficacy.


Country Year Research Type % Increase in grain yield % Reduction in pesticides
Mexico 2005 FDT aerobic + 9.5% - 35%
India 2007-2008 UARS wetland + 32% - 50%
India 2008-2009 UARS wetland + 35% - 50%
India 2009-2010 UARS aerobic + 43% - 50%
India 2011 UARS wetland + 32% - 50%
Suriname 2013 FDT wetland + 37.5% - 100%
