230 JOURNAL OF ECONOMIC ENTOMOLOGY [Vol. 9 



devoted to this work we are receiving large quantities of imported 

 shipments of nursery stock from abroad which we feel must be given 

 very prompt and careful attention. We have also had for past two 

 years a gypsy moth outbreak to contend with and this, of course, 

 has necessitated strict attention. 



San Jose scale is a well established pest in the state of Ohio. In 

 three-fourths of the state or throughout the level portions, the in- 

 festation is general and it is the exception to find an orchard free from 

 this insect. In the other portion of the state which is hilly, it is rarely 

 that an orchard is found infested with San Jos6 scale, and in this 

 section are located our largest commercial apple orchards. In the 

 infested area are many localities and many orchards where scale is 

 under perfect control and is causing no particular injury or loss. 

 This is due to the extensive campaign which is being waged for the 

 proper treatment of farm orchards for insect control. 



Over 11,000 people attended our orchard demonstrations during the 

 present year. 



So far as Ohio is concerned, we would feel that we were giving our 

 planters of Ohio grown nursery stock adequate protection by carefully 

 supervising the fumigation of nursery stock, destroying those stocks 

 which are more than slightly infested and thus possibly might be 

 weakened from scale attack. It seems rather unreasonable, in view 

 of conditions as we know them to exist in Ohio and in the eastern and 

 central states as well, to require the wholesale destruction of infested 

 stock. I do not mean to say that we should recede at all from our 

 position of having nurserymen use every precaution to protect their 

 stock from infestation. The fact that our nurserymen have not taken 

 advantage of the Ohio provision allowing them to dispose of scale 

 marked stock within the state, would indicate that they are not 

 inclined to take any backward steps in fighting San Jose scale. 



We would feel perfectly safe in accepting from other states, stocks 

 which would be given the same careful fumigation treatment that we 

 are attempting to carry out in Ohio. We would feel that purchasers 

 ■of nursery stock in this state were getting better protection than they 

 are under present methods, as indicated by our findings this year. 



At four of our nurseries receiving stock from nurseries located in 

 eeven other states within a radius of 400 miles and less of Ohio, we 

 have found over 30,000 stock infested with San Jose scale and infected 

 by crown gall in about equal numbers. In one shipment of 70,000 

 trees the infested and infected trees amounted to 15 per cent of the 

 entire shipment. Bear in mind that these findings were made at four 

 of our nurseries. If it were possible to inspect the vast quantities of 

 stock which came into the state through agents and dealers, the count 

 would be much larger. These inspections of incoming stock at the
