INJURIOUS INSECTS OF I909Q AND IQIO. 59 
MINNESOTA NURSERY INSPECTION: 
INSPECTION OF IMPORTED EUROPEAN STOCK. 
1909 and 1910. 
Our inspection of state nurseries appears to be on a satisfactory 
basis, at least for the time being. The state law, it is true, is some- 
what lax; but, at a conference of some of our leading nurserymen 
and the entomologist, it was not thought advisable to attempt any 
change in IQII, in view of the possibility of a federal law in the 
near future. Letters from nurserymen not in attendance at this 
conference expressed practically the same views as those given at 
the meeting, namely, satisfaction with the present law and the way 
it was administered; with a feeling that no change should be made 
until something decidedly better should be offered in its place. 
In 1909 nurseries looked vigorous and thrifty. The growth of 
apples, shrubs and canes was generally very striking, the best for 
years. There was plenty of apple aphis, though damage from this 
insect was slight. The apple leaf-hopper was also abundant; but the 
trees were making such a vigorous growth, beiore the hoppers put 
in an appearance, that growth was not materially checked. Other 
insects in evidence were the Poplar and Willow Beetle, Melasoma 
scripta, doing much damage in some of the Southern nurseries to 
young poplars, but easily kept in check by proper spraying with 
arsenate of lead; the Plum Curculio and Codling Moth in orchards; 
the Eight-spotted Forester, the Leaf-roller of the Basswood, Pan- 
tographa limata, the Fall Web Worm, the Oyster-shell Scale, and 
various leaf-eating caterpillars. 
Mr. Ruggles, who did the inspection in 1909, also reported the 
following diseases in orchards and nurseries: Crown Gall on rasp- 
berries, Anthracnose on raspberries, Leaf Blight on box elder, Pear 
Blight (Fire Blight), Scab. 
The crown gall on raspberries was very abundant. He reported 
it as being more abundant where plants had been disturbed than in 
beds not so disturbed, and advances the theory (which is perfectly 
possible) that the cutting away of the young plants, leaves wounds
