Which product should be avoided on bentgrass?

• A. Pendimethalin.
• B. Barricade.
• C. Betasan.
• D. Princep.

Answer: (A)

Bentgrass greens require herbicides with proven safety for that specific turf. Creeping bentgrass is very sensitive to many chemicals, so choosing products that are labeled as safe for use on bentgrass greens is crucial. Pendimethalin, a preemergent used to curb annual grasses, can cause phytotoxic injury to bentgrass when applied at typical greens rates or under common growing conditions. This injury can show up as thinning, yellowing, or uneven patchiness, which compromises the smooth, uniform surface that greens demand. Because of this higher risk of damage, pendimethalin should be avoided on bentgrass. The other products listed have established label guidelines for use on bentgrass greens, making them safer options when applied according to the label.
