a synergistic mix of organic acids and compounds for plants and soil.
Persist™ PAF is a unique blend of organic acids (OA) and natural compounds. Academic research and trial data confirm the critical role of OA in creating more vigorous plants and more productive soils.
Explore the Science
The organic acids and phenols in PAF have been found to help regulate crucial physiological functions in plants to provide resistance against biotic and abiotic stresses, including drought, heat, pathogens, salinity, insect pressure, UV radiation, and heavy metal contamination.
Persist™ PAF contains readily degradable organic acids and compounds that microbes use for metabolism, enhancing both the diversity and population of beneficial microorganisms in the soil. A robust microbiome is crucial to rich, fertile, and productive soils.
Organic acids in PAF, such as malic and acetic acid, have been shown to solubilize and mobilize minerals such as Fe, P, K, and Mg. These organic acids form complexes with soil minerals to release previously unavailable nutrients for plant growth and development.
Karrikins — molecules derived from plant material smoke — have recently been identified as important plant growth regulators. Plants have evolved to respond quickly to these “smoke compounds,” which are found in Persist’s new PAF-based “Karrikaid” liquid nutrient.
14% Yield Improvement
Strawberry Production Trial (Fall 2022)
Compared to the grower’s standard regimen, the yield of marketable strawberries per acre improved by 14.25%* when adding Persist™ Biochar and Persist™ PAF liquid plant enhancer.
Before planting, biochar was placed in the slot at a rate of 480 lbs/acre. 1% diluted PAF was foliar applied at a total rate of 3.5 gal/acre (four applications total). The trial was conducted by Holden Research and Consulting (Camarillo, California).
* Extrapolated flats per acre compared to the grower’s standard.
PAF Provides Greater Root Growth and Total Plant Weight
Celery Nursery Trial (Winter 2023)
Two foliar applications of Persist™ PAF were applied during the outdoor nursery trial. PAF positively impacted plant development, including a 72% improvement in bottom root growth and a 31% improvement in total plant weight. The trial was conducted by Holden Research and Consulting (Camarillo, California).

* Follow the application methods, rates, and coverage areas as prescribed by your specific nutrient and fertilization regimen. Do not apply PAF more than once every two weeks. As an example, a dilution rate of 1:500 means one-part PAF diluted with at least 500 parts of water.
