Origin2023
Horizon Ag occupies the seed marketing niche within the US Mid-South rice belt — the Arkansas, Louisiana, and Mississippi Delta region that produces approximately 40-50% of US rice. The company partners with BASF (for Clearfield herbicide-tolerant rice, which uses imidazolinone herbicide tolerance bred through conventional mutagenesis rather than genetic modification) and Bayer (for Provisia rice, which uses rice cultivars tolerant to quizalofop herbicide). Both herbicide-tolerant rice systems were developed to address the industry's most serious agronomic problem: red rice (wild-type Oryza sativa) contamination of commercial rice fields — red rice reduces yield and downgrades rice quality for export because of the hulls remaining in the grain. Conventional selective herbicides cannot kill red rice without also killing crop rice; herbicide-tolerant varieties allow effective red rice control. Horizon Ag's seed marketing role is to take varieties bred at university programs (University of Arkansas, LSU) or developed by BASF and Bayer and deliver them to Mid-South rice farmers through the Delta's independent seed dealer network. The company embodies how the US rice seed supply chain is structured: university-bred genetics, licensed to multinational agrochemical companies who pair them with proprietary herbicide systems, distributed by regional seed marketing companies to local dealers serving family farm operations.
