The Minister may make Orders for preventing introduction of destructive insects or pests or agents for the biological control of plant pests. Such Order, under this section 3, may prohibit or regulate the landing in the State of any article brought from a place out of the State, the landing whereof may appear to the Minister likely to introduce any destructive in or pest or any agent for the biological control of plant pests into the State, and may direct or authorize the destruction of any such article, if landed. The Minister may also make Orders for preventing spreading of destructive insects or pests or agents for the biological control of plant pests under section 3. Section 4 provides for the compensation for destroyed crops.
