The method for disinfecting fruit trees required to be disinfected under the provisions of this chapter shall be as prescribed in the official published recommendations of the Washington State University for the proper prevention, control and eradication of pests and diseases of fruit trees.
Whenever specific recommendations for disinfecting fruit trees are not set forth in the official published recommendations of the Washington State University, the generally accepted horticultural practices for the prevention, control and eradication of any pests and diseases in the producing area shall be used.
The burden of proving that the proper procedures as set forth in this section have been followed shall be upon the person ordered to disinfect fruit trees.
The disinfection of fruit trees as in this section set forth shall in no way limit the authority of the inspection board to determine that such fruit trees constitute a nuisance and thus shall be subject to removal as provided for in this chapter.
