Final answer:
It violates the Ohio pesticide law and/or FIFRA to use a pesticide on a crop not listed on the label, operate faulty or unsafe spraying equipment, and use a pesticide at a higher concentration than is stated on the label.
Step-by-step explanation:
Regarding violations of the Ohio pesticide law and/or the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), it would indeed be a violation to engage in certain activities. Specifically:
- Using a pesticide on a crop not listed on the label
- Operating faulty or unsafe spraying equipment
- Using a pesticide at a higher concentration than is stated on the label
Each of these actions can have serious negative effects on human health, the environment, and non-target species. Doing any of these can lead to significant penalties, as they undermine the regulations set forth to minimize the risks associated with pesticide use. Therefore, the answer to the student's question is d. All of the above are correct.
