January 2021 – Member News Update

November 25, 2020
EPA Updates Draft Guidance for Plant Regulator Label Claims, Including Plant Biostimulants
Yesterday, the EPA released a newly updated draft guidance document clarifying which biostimulants, biological substances, and mixtures, in addition to the associated product label claims, EPA considers plant regulators. Those deemed plant regulators are subject to regulation under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) as pesticides.

Because this guidance impacts humic substances, HPTA members are encouraged to read the document and submit a public comment directly to the open docket on the website.  The proposed changes to humic and fulvic acid could significantly impact the humic and fulvic acid industry. The updated draft guidance incorporates diverse and helpful changes made in response to stakeholder feedback received during the draft guidance’s initial comment period in 2019. EPA seeks inputs on those revisions, including the wording of certain plant and non-plant regulator claim examples.

The public comment period will be open for 30 days in docket EPA-HQ-OPP-2018-0258 at After carefully considering the comments received, EPA anticipates finalizing this guidance in January 2021.

Humic Products Trade Association: Biostimulant Policy Initiative Update
As required by the 2018 Farm Bill, the United States Department of Agriculture (USDA) issued a report to Congress detailing options that could clarify the regulation of Biostimulants. Unfortunately, the USDA Biostimulant report sent out in December of 2019 indicted six options that offered very little clarity to congressional members or a preferred path going forward.  In response to this USDA report, HPTA, along with other key industry organizations, drafted a joint position letter outlining and affirming our position on policy developments for biostimulants.
Members wishing to read a copy of the joint response can find the correspondence linked here:  Industry Position Paper USDA Report 3.30.20.

CDFA Approves use of HPTA Test Method Seal  

HPTA members can now use the HPTA Test method and seal on products sold in California, provided the humic acid guarantee on the label is valid when also tested with the current CDFA method and follows the guidelines outlined in the January 16th letter from Dr. Dale Woods, CDFA Environmental Program Manager.

This decision applies only to the humic acid and does not include fulvic acid (yet).
