in Michigan, and what \vc have been able to do iu connection with the 

 regular work of this depaitment, 



INSPECTION OF IMPORTED NURSERY STOCK. 



Owing to the Federal quarantine against nursery stock from foreign 

 countries very little stock lias come in, except bulbs from Holland and 

 Belgium. During the fall inontlis many hundred cases were insijected 

 and were found in good condition excei)t a few cases of narcissus bulbs 

 whicli we were obliged to destroy. They were infected by various mites, 

 and with tbe narcissus fly, which is especially to be feared, since it also 

 attacks the onion. 



The other imports consisted of nearly one million apple, pear, plum, 

 cherry, and rose stocks from France and England. These slocks were 

 poorly packed and arrived in such a condition that many thousand could 

 not be used. They were free from dangerous insects and diseases, but 

 the importance of continuing this inspection service was shown by the 

 finding of clusters of gipsy moth eggs upon similar shipments in one 

 or two other states. 



STATE QUARANTINES. 



Quarantine No. 1 against shipment into Michigan of five leafed pines, 

 currants and gooseberries from New England, New York, Wisconsin and 

 Minnesota; and Quarantine No. 2, against shipment of the common 

 barberry and mahonia are still in force. The latter will remain as a 

 permanent quarantine, but Ave hope to be able to modify tlie blister 

 rust quarantine so far as it relates to shipments of gooseberries and 

 red and white currants from the nursery section qf Central New York, 

 provided the inspections made during the present season indicate that 

 it can be done with safety. 



Owing to the spread of the European Corn Borer in New England 

 and its appearance in New York and Pennsylvania, it was deemed best 

 in March, 1920, to quarantine shipments from those sections which were 

 likely to harbor this insect. In addition to the stalks and ears of corn 

 of all kinds and broom corn, such vegetables as have edible leaves or 

 stems, were included in the quarantine, as well as herbaceous perennials 

 which are shipped with their old stems attached, and hardy shrubs which 

 have a large pith. Straw, whether to be used as such, or as packing 

 material, is also covered by the quarantine. 



To this report is appended a list of the Michigan nurseries licensed 

 and inspected during 1919-20, and also the dealers and nurseries in other 

 states which have a license to sell nursery stock in Michigan:
