In connection with an emergency in which a plant pest or noxious weed threatens any segment of the agricultural production of the United States, the Secretary may transfer from other appropriations or funds available to the agencies or corporations of the Department of Agriculture such amounts as the Secretary considers necessary to be available in the emergency for the arrest, control, eradication, and prevention of the spread of the plant pest or noxious weed and for related expenses.

Any funds transferred under this section shall remain available for such purposes without fiscal year limitation.

The action of any officer, employee, or agent of the Secretary in carrying out this Act, including determining the amount of and making any payment authorized to be made under this chapter, shall not be subject to a review by any officer or employee of the Federal Government other than the Secretary or the designee of the Secretary.
