Lawn chemicals refer to which of the following?

• A. Lawn chemicals refer to fertilizers, pesticides, or defoliants applied or intended for application to lawns.
• B. Lawn chemicals are soil amendments used for turf health
• C. Lawn chemicals are tools used for mowing and maintenance
• D. Lawn chemicals are pesticides used only on crops

Answer: (A)

Lawn chemicals are any chemical products that are applied to or intended for application to turf to influence its growth, health, or pest control. This broad category includes fertilizers, which feed the grass; pesticides, which cover herbicides, insecticides, and fungicides used to manage pests and diseases on lawns; and defoliants, which cause leaves to fall and may be used in certain turf-management practices. Because these products are applied to lawns and fall under regulatory labeling and usage rules for turf, they fit the definition of lawn chemicals in this context. The other options don’t fit because soil amendments used solely for turf health aren’t always described as lawn chemicals in the regulatory sense, mowing tools aren’t chemicals, and pesticides used only on crops don’t cover lawn applications.
