To provide for the eradication of the citrus white fly, the director may by proclamation declare any portion of the state where the citrus white fly is known to exist to be a citrus white fly district.

The proclamation shall state both of the following:

The director shall print a copy of the proclamation in one or more papers of general circulation in the infested district.

Every plant within a citrus white fly district which is infested with citrus white fly or with the eggs, larvae, or pupae of the citrus white fly, or which there is reasonable cause to believe may be infested with citrus white fly, is a public nuisance.

The existence of any known host plant of citrus white fly within the boundaries of the district is reasonable cause to believe the host plant is infested with the citrus white fly.

The department and the commissioners may cause the destruction of any host plant of the citrus white fly in a summary manner.

If, in the opinion of the enforcing officer, the host plant may be treated in a manner to destroy all citrus white flies or the eggs, larvae, or pupae of the citrus white fly which are or may be on the plant, the officer may in a summary manner cause such treatment to be given.
