Question

the toxicity of a pesticide is determined by ______.
a. smelling the product
b. calling the manufacturer
c. reading the label
d. testing in a small area

Explanation:

To determine the toxicity of a pesticide, the label provides official, regulated information about its toxicity (like LD50 values, hazard statements). Smelling (a) is unsafe and not a valid method. Calling the manufacturer (b) is not the primary or standard way. Testing in a small area (d) is for efficacy or sensitivity, not toxicity determination. Reading the label (c) is the correct approach as labels have required toxicity - related info.

Answer:

c. reading the label
