Summary

The Wonderful Company is California's top user of the herbicide glyphosate, using 328,000 pounds in 2023, according to data analyzed by Mother Jones. The company's use of glyphosate raises concerns among health-conscious and environmentally minded individuals, despite its claim that it uses the herbicide only for weed control in compliance with government guidelines. Two-thirds of Americans favor banning glyphosate use, including 70% of Republicans and 69% of Democrats, according to a recent survey. The Wonderful Company's use of glyphosate may be surprising given its touting of its food brands as health products.

Story summary

The Wonderful Company, a private firm owned by Stewart and Lynda Resnick, is the largest user of the herbicide glyphosate in California, applying 328,000 pounds of it in 2023, according to records analyzed by Mother Jones. This amount accounts for about 68% more than the next highest user in the state. The widespread use of glyphosate in California is notable because the state produces a significant portion of the country's agricultural products, including nearly half of its vegetables and over three-quarters of its fruits and nuts. Glyphosate has been at the center of controversy due to concerns about its impact on human health and the environment, with many lawsuits settled for over $12 billion and opposition from labor and environmental groups.

Narrative

Other notable glyphosate users in California include Caltrans (#5), the state transportation agency, which applies it for aesthetic and safety reasons, including fire prevention and weed reduction along highways to improve drivers’ lines of sight; John Hancock (#12), the financial company that owns almond and pistachio farms; Gallo (#14), the largest family owned winery in the United States; Fondomonte (#16), a Saudi-owned company that has been criticized for sucking up scarce groundwater to grow hay (which it then exports) in the Arizona and California deserts; and California State Parks (#36), which manages 1.6 million acres of public land.

it → say → almonds
