 the County Entomologist to promulgate rules which are consistent 

 with the state law concerning the details of its execution as far as it 

 relates to county work. He should be authorized to quarantine 

 against the importation of nursery stock or plants of any kind from 

 other counties, and to make such inspections as they may deem advis- 

 able of nursery stock or plants imported from other counties in the 

 state or from other states or territories and from foreign countries. 

 He should be authorized to require defoliation, treatment with 

 insecticides or the fumigation of plants imported into the county from 

 other counties, or of plants offered for sale within the county when 

 necessary to prevent the spread of insect pests. He should be 

 authorized to inspect nurseries, orchards, groves, vineyards, trees, 

 vines, plants and fruits as far as practicable to protect the horti- 

 cultural interests within his jurisdiction and to serve legal notices 

 requiring specified measures for the control or eradication of insect 

 pests when necessary. He should be authorized to enter upon any 

 premises at any time for the purpose of performing any of the 

 duties required of him by the law. Authority should be given to 

 the county entomologists to regulate, with the approval of the 

 county commissioners of the respective counties, the planting of new 

 citrus groves so as to prevent in the future losses to owners of isolated 

 groves or groves in isolated groups through the interference with the 

 advantages of such isolation, also, so as to prevent new plantings 

 interfering in any way with the control of the whitefly or other pests 

 in groves already estabhshed.

 infested trees, plants or premises pubhc nuisances and to serve a legal 

 notice as heretofore stated requiring specified remedial measures or 

 methods of eradication within a specified time. When any person or 

 persons upon whom such notice has been served refuses or neglects 

 to abate the nuisance as directed, or when, owing to the absence from 

 the county of the owner or owners, it is impossible to serve the notice, 

 it should be the duty of the County Entomologist to cause the nuisance 

 to be abated by means of the most economical control measures avail- 

 able, including when necessary, the complete or partial destruction 

 of the infested plants, fruits or articles. When performed by the ento- 

 mologist or his authorized assistant, the expense should be borne by 

 the county and become a lien on the property subject to legal action
