4» At the same (Arizona) Station, J« G, Brown found (p» 3) in similar tests 

 that those antibiotic materials acted only upon the diseased tissues, 

 killing the gall cells and causing the galls to disintegrate, but having 

 no effect upon the healthy host tissue (root, stem, branch) from which 

 the galls had developed. 



5, Fernate concentrate spray from airplane for apple rust control; A. B. 

 Groves, u» Va, Station (p, 11). A single application Hay 11 on York 

 and Y/inesap trees, using 7,5 oz, of Fermate per gallon of water, at 

 the rate of 8 gallons per acre, gave a reduction in cedar rust spots 

 of over 94%, 



6, Sour cherry susceptible to the peach X-Disease; D, H. Palmiter and 

 K, G. Parker, New York Station (p. 20). English Morello and Mont- 

 morency cherries growing near X-diseased chokecherries and peach trees 

 showed virus-like sjTiiptoms, Graft and bud inoculations into peach 

 trees from diseased cherry trees produced typical X-disease symptoms 

 in the peach trees. Corresponding symptoms were produced on sour 

 cherry trees by inserting buds from X-diseased chokecherries. As a 

 result of this disease, 55>o of the trees in one English IJorello 

 orchard produced no fruit in 1947* 



7* Apple bitter rot reported on fruits of sour cherry; Clyde E. Feet 

 and Carlton F. Taylor, VJ. Va, Station (p. 20)* Dry sunken rot v/as 

 produced on one side of the fruit with typical pinkish spore masses, 

 with up to 15yo of the fruits affected in some trees. Successful 

 inoculations of apple fruits proved the correct identity of the 

 fungus, 



8. Apple bitter rot on peaches; G, B. Ramsey, M, A. Smith, and B, C. 

 Heiberg, U.S,D,A, (p, 22). Certain shipments of peaches in northern 

 markets from Georgia during July 1947 showed brovvn, dryish lesions 

 from one-fourth to three-fourths inches in diameter vath typical 

 bitter rot pinkish spore pustules. Inoculations produced typical 

 bitter rot on apples and pears, also similar lesions on peach and 

 plum fruits,

50th Anniversary of the Cortland Apple The original 

 cross between Mcintosh and Ben Davis which resulted in 

 the Cortland variety is said to have been made in 1898, 

 just 50 years ago, and the first tree bore its first 

 apple around 1906, It vms introduced about 1915. The 

 intervening years have seen thousands of tests of this 

 variety, it has been tried under all sorts of condi- 

 tions as regards soil types, spray programs and storages, 

 V/e believe it has stood the test fairly well and is 

 today well established as one of our fairly important 

 varieties. Certainly its reputation has improved during 

 the past 10 years. Possibly the old saying, "It takes 

 60 years for an apple variety to prove its worthv/hile- 

 ness" is partially true.
