Report of A. H. Carson. 37 



We made an examination of these trees and found them dis- 

 eased with the blight. I instructed Mr. Lyons how to treat 

 the trees and cut out the diseased germs, which he Dromised 

 to do the next morning. Mr. Lyons cut out the diseased twigs 

 on three of his trees, and left two trees that showed but a 

 slight mdication of the disease. In July, 1909, I was in both 

 the Hays and Lyons orchards. The two trees Mr. Hays and 

 I treated were healthy and free of the disease, nor was there 

 a tree to be found in the Hays orchard but was free of the 

 blight. At the same date the Lyons orchard was examined, 

 the^ three trees he had treated were healthy, and free of the 

 disease. The two trees in this orchard which in 1908 showed 

 but slight infection and were not treated, were nearly dead 

 in July, 1909, with the blight. His (Lyons') neglect to cut 

 out the few diseased tv/igs had evidently permitted the devel- 

 opment of hold-over blight, with the result that more than 

 fifty apple and pear trees in the vicinity of these trees had 

 become diseased with the blight. The Lyons orchard is east 

 of the Hays orchard, and the trees that were infected from 

 the hold-over in the trees neglected were around these neg- 

 lected trees. In that locality the prevailing wind in spring 

 is from the west. The bee, the germ carrier, fed upon the dis- 

 eased sap that flowed from the hold-over, and was the cause 

 of so many trees being diseased with the blight in the Lyons 

 orchard. The disease is now in Douglas County, but I have 

 every confidence of Controlling it through the activity of 

 Inspector McCall, of that county. We know the results of the 

 blight in California, the loss the orchard men of that state 

 had a few years ago. Also, we know what the blight has 

 done for eastern pear growers. To save the pear orchards 

 from this disease, when now we know it can be done. (thank- 

 ing Professor O'Gara for teaching us how), should we not 

 alarm the apple and Dear growers of this State to a realiza- 

 tion of the danger of the disease, as the people of Jackson 

 County are now alarmed, and exterminate it as they are doing? 

 Jackson County, with her large acreage, is making a success- 

 ful and determined fight, with O'Gara at the head of four 

 inspectors who work every day. A large acreage in orchard 

 takes much help, and Jackson's county court, alive to the 

 necessity of the Situation has given me four inspectors who 

 are succeeding. We should at all times antagonize the adver- 

 tised rem.edies. There is no spray that can reach the blight. 

 The only remedy is to cut it out. 



Many growers mistake the pear-blight for apple anthracnose. 

 Apple anthracnose is a fungus disease, and the remedy for the 

 disease is spraying with bordeaux early in the fall. The bor-
