FRESNO, Calif. — Regulators in California took a pivotal step on Monday toward becoming the first state to require the popular weed killer Roundup to come with a label warning that it’s known to cause cancer.

Officials announced that starting July 7 the weed killer’s main ingredient, glyphosate, will appear on a list California keeps of potentially cancerous chemicals. A year later, the listing could come with warning labels on the product, officials said.

However, it’s not certain whether Roundup will ultimately get a warning label.

Monsanto, the chemical’s maker, has filed an appeal after losing in court to block the labeling, arguing that Roundup doesn’t cause cancer and that the labels will harm the company’s business.

State health regulators must also decide if there’s a high enough amount of the chemical in Roundup to pose a risk to human health. State officials received more than 1,300 public comments.
