INFORMATION FOR IMPORTERS OF ELM BURL LOGS UNDER THE DUTCH ELM 
DISEASE QUARANTINE NO. 70 
The Dutch elm disease quarantine aims to keep out of this country both 
the causal fungus (Graphium ulmi) and the insects which are reported to 
spread it in Europe (Scolytus spp.). While this object could be attained most 
surely by shutting out entirely all plants and all wood of elm and its relatives, 
it has been decided that, if certain safeguards are taken, the entry of elm 
burl logs can still be permitted with safety. The quarantine states these safe- 
guards and provides that they shall be carried out under the supervision of 
the Bureau of Plant Quarantine. The essential features of this quarantine 
are here listed, with some explanation of the bearing of each on the problem 
of the safe entry of logs. 
freedom of logs from bark 
Shipments of these elm logs from Europe have recently been found so gen- 
erally infested with elm bark beetles that it is not considered safe to allow 
logs with bark to enter the country, even if treatment could be given promptly 
at the port of first arrival. In view of the efforts now under way to eradicate 
the disease in this country it is not considered justifiable to take the risk of 
escape of these beetles during the course of unloading and transportation to 
a treating plant. Consequently, logs arriving with the bark on will be refused 
entry and must be removed from the country immediately or destroyed. 
FREEDOM OF LOGS FROM WOOD-INFESTING INSECTS 
If the bark is removed in Europe there is apparently little danger that the 
elm bark beetles will be present when the logs arrive here. However, the 
Department feels obliged to assure itself that neither these beetles nor other 
wood-boring insects are infesting these logs either at time of entry or at 
any time before the logs are treated. 
PROPER STORAGE 
From the quarantine point of view proper storage means holding the logs 
in a place where wood-infesting insects will not have ready access to them
