NURSERY INSPECTION. 

 Report of Nursery Inspection in Pennsylvania. 



During the past year tiie inspection of nurseries has been pushed with more 

 than usual vigor, during both the summer season and the winter. This is the 

 second year that we have inspected nurseries during the wintertime, and the 

 results are found to be so beneficial that it is determined to continue this fea- 

 ture of the inspection. The summer inspection commences the first of August 

 and is continued until all the nurseries of the State are thoroughly inspected, 

 which is generally until about the middle of September. However careful and 

 conscientious the Inspector may be at the time of inspection, it is impossible 

 to find all the scale insects that may be concealed beneath green leaves and 

 buds during the summer inspection, and also there is great danger that the 

 scale may spread after this inspection is finished and infest nursery stock 

 which was clean at the time it was inspected. 



In order to be certain to find the San Jose Scale and other tree pests, the 

 February inspection is made when the trees are not in leaf, and there is a 

 better opportunity to inspect them thoroughly and see that they are in proper 

 condition for spring sales. The inspections have been made with greater 

 care than ever before, and the nurserymen themselves have commended it and 

 commented upon the thoroughness with which the present force of inspectors 

 are doing their work. The results are gratifying to all parties concerned. 



When the nursery inspection was first undertaken, some of the nurserymen 

 were opposed to it for the reason that they thought it was interfering with 

 their rights and property, and that they should be permitted to sell the nur- 

 sery stock grown on their own land if the infestation came by means for 

 which they were not responsible. They now fully understand that to stay in 

 the business permanently and continued to make sales, they must of necessity 

 sell good stock in good condition and satisfy customers. Thus they have 

 become enthusiastic supporters of a very rigid system of nursery inspection. 



The greatest evil threatening nursery stock in this State has been infested 

 trees or shrubbery in the vicinity of nurseries, and the great danger of the 

 San Jos6 Scale spreading readily from such trees to the nursery stock. Sev- 

 eral cases of nursery infestation by such means were found by our inspectors 

 a few years ago, and this justified the movement on our part to force the 

 owners to rid their trees of such dangerous pests. As a consequence, last 

 summer we gave considerable attention to inspecting trees and shrubs on 

 premises in the vicinity of nurseries, and notified the owmers that their prop- 

 erty must be treated by certain means or it would be our duty to treat it or 

 destroy it in order to get rid of the scale threatening the nurseries, nursery 

 stock and neighbors. We are much gratified to report that in every case prompt 

 remedial action was taken by the owners, and the results are very gratifying 

 to all parties concerned. Nurserymen report that they have had during the 

 past season far less infestation from scale from surrounding premises than ever 

 before, which we believe is attributable to this method. 



Where trees are found infected in a nursery this State requires the destruc- 

 tion of all those that are found infested by San Jose Scale, and the fumi- 

 gation of all others from that nursery before they can be sold or shipped. 

 There has been considerable complaint made against fumigation, some persons 

 claiming that it injured their trees, but we know of a series of fumigation 

 experiments which proved that three times the required dosage of one ounce 

 of the Cyanide of Potassium to one hundred cubic feet of space resulted in no 

 injury whatever to the trees or cuttings. It is by all means best to have 

 nursery stock fumigated at the nursery before shipping, whether it be found 

 infested or not. The reports adverse to fumigation have mostly come from 

 persons who wished to be excused from the trouble of insuring, by this method, 

 the freedom of their trees from pests. 



It is against the law to ship any nursery stock, of varieties subject to attack 

 by San Jose Scale, into this State from any other state or country without 

 certificates both of inspection and fumigation being attached to each package, 

 bale or bundle in the shipment. Persons who have an opportunity are invited
