What conditions must be met for a pesticide to be registered by the BPA?

For a pesticide to be registered by the Board of Pesticide Control (BPA), it must meet several important criteria, which is why the correct choice is that all of the mentioned conditions must be satisfied. Specifically, long shelf life, minimal environmental impact, and cost-effectiveness for farmers are all vital aspects of the evaluation process.

A long shelf life ensures that the pesticide remains effective and safe for use over time, providing confidence for users that the product will perform as intended until it is used. Environmental impact is a critical consideration since pesticides can affect non-target organisms, ecosystems, and water sources; thus, demonstrating minimal environmental harm is essential for registration. Additionally, cost-effectiveness is important for practical use in agriculture, as it substantially affects a farmer's decision to adopt a pesticide; if a pesticide is too costly, it may not be feasible for widespread use despite its effectiveness.

In summary, for a pesticide to receive registration, it must not only perform well but also be safe for the environment and economically viable for farmers. Therefore, meeting all these factors collectively justifies the registration process by the BPA.
