Princep (simazine) is labeled for use on which grasses?

• A. Zoysia and bermuda only.
• B. Bentgrass greens.
• C. Tall fescue.
• D. All grasses.

Answer: (A)

Understanding how herbicide labels guide where you can use a product is essential. Labels specify which grasses are listed as safe or appropriate for a given chemical. Princep (simazine) is approved for use on warm-season turfgrasses, specifically bermudagrass and zoysiagrass. It is not listed for cool-season grasses like bentgrass greens or tall fescue, so applying it to those grasses could injure the turf and would not be allowed by the label. That makes the option mentioning zoysia and bermuda only the correct choice, as it reflects the grasses the product is labeled for. Choices that include bentgrass greens, tall fescue, or all grasses don’t fit because the label doesn’t authorize those uses.
