 Report of Committee on Treatment of Scale-ixfested Nurseries 



The committee appointed, at the Boston meeting of the Association to inquire 

 into methods of dealing with nurseries infested with San Jose scale and to make 

 specific suggestions pertaining thereto begs to report as follows: 



As soon as the bulk of inspection work for 1910 was disposed of in our own states, 

 the committee began an inquiry, sending letters to the proper authorities in each 

 state as shown by the lists of the secretary of this Association. 



In several instances no replies were received, — in one or two cases it was declined 

 to discuss the matter, — in several cases merely the legal requirements of the state 

 were mentioned without any description of the real methods of exact work done. 



Your committee is glad to report, however, that a goodly number of satisfactory 

 replies were received, for the most part from states where this work is of prime im- 

 portance, — and in several instances hints or suggestions were given which we hope 

 will be of interest. 



The overwhelming testimony of the inspectors is in favor of the following genera 

 scheme of treatment for nurseries infested with San Jose scale. 



Treatment of Scale-infested Nurseries 



1. A close general inspection to determine exact extent of infestation. 



2. Every tree or plant actually seen to be infested destroyed. 



3. Second inspection, if possible (tree by tree, if practicable) late in season or at 

 digging time. 



4. Fumigation of all stock remaining, after destroying all visibly infested trees. 



In some states the fumigating is done by the inspectors, — in others the nurseryman 

 signs an agreement or affidavit to do it and it is left to him, — in others it is required 

 by law of all nurseries and left to them (with complete instructions) except in the 

 worst cases, which are fumigated by the inspector. 



Modifications practiced by different inspectors which are believed to make for 

 better results are as follows: 



1. In one state all cyanide is furnished through the inspector's office, thus insuring 

 good, uniform grade and proper doses. 



2. In one state it is required to spray all growing stock in nurseries where scale 

 has been found with result that infestation is rendered less from year to year. 



3. In one state a special form of certificate (stating that part of the stock was 

 found infested), is issued to infested nurseries. No nurseryman would want such 

 a certificate if he could possibly get a clean certificate. 



4. One inspector destroys every plant found infested and all around it for a dis- 

 tance of twenty to thirty feet. 



5. In one state all inspections after the first are charged for, the fee based on 

 infested acreage involved, — so a nurseryman seeks to avoid more than the one 

 regular inspection, which is free. In another state where second vnsit is needed or 

 fumigation done by inspector, the whole expen.se is charged to the nurseryman. 



6. Some states withhold the certificate until all the work of the inspectors has 

 been completed.
