e. That the applicant or permit holder has failed to demonstrate that he has sufficient knowledge and experience concerning the proper use, application and disposal of pesticides.

5. A formal hearing shall not be required and the commissioner's decision in denying or revoking a permit shall be final unless the applicant or permit holder institutes a review within the time and in the manner prescribed by article 78 of the Civil Practice Law and Rules.
