Is Stutzerimonas stutzeri an AAPFCO-listed plant biostimulant, and what claim language has AAPFCO accepted?
Stutzerimonas stutzeri — widely recognized by its former name Pseudomonas stutzeri — appears in the AAPFCO plant biostimulant source data as group 187, making it one of the recognized microbial inputs under the association's biostimulant classification framework.
Under this lens, AAPFCO accepts two claims for Stutzerimonas stutzeri: nitrogen fixing, and the potential to help increase phosphate and iron availability in soil. Growers and formulators researching 'Pseudomonas stutzeri nitrogen fixation' or 'Stutzerimonas stutzeri biostimulant claim' will find that these are the specific, accepted statements — no broader efficacy claims are on record in this dataset.
For manufacturers evaluating whether Stutzerimonas stutzeri qualifies as an AAPFCO biostimulant source material, group 187 status confirms it is listed. The accepted nutrient-availability language is narrow: phosphate and iron, framed as a 'may help' claim, not a guaranteed agronomic outcome. No additional AAPFCO claims are reflected in the indexed data for this input.
