True or False: The words "Keep out of reach of children" must appear on all pesticide labels.

The statement is true because federal regulations require that all pesticide labels bear the precautionary statement "Keep out of reach of children." This requirement is in place to ensure safety and to minimize the risk of accidental exposure by children, who may not understand the dangers associated with these substances. Including this warning on pesticide labels is part of broader efforts to protect public health and safety, making it essential for all manufacturers to comply regardless of the specific type or category of pesticide.

In the context of the other options, while synthetic pesticides and agricultural pesticides have specific guidelines regarding their use, the general requirement to keep all pesticides out of reach of children applies universally across all types of pesticide products.
