514 Report of the Department of Horticulture of the 



what promised to be a full crop the writer picked one apple at harvest 

 time. The plats in the hillside orchards escaped both freezes. 



The trees in all of the plats have had their full share of the usual 

 insect and fungus troubles but so far as could be seen from careful 

 observation, though not special study, pests were as numerous and 

 troublesome in one section of the plats as another, with the single 

 exception of blight. The Alexanders, always susceptible to blight, 

 suffered more from this disease in the tilled than in the sodded 

 sections. Seven trees under tillage were killed by the blight in 

 Plat B. Red-bugs came in devastating numbers in B and C 

 in 1905 and have reappeared every year since, preventing the division 

 of the crops into market grades in accordance with size, since injured 

 fruits, no matter what their size, had to be put into seconds or culls. 

 In 1913, however, this pest was kept under control by spraying 

 with Black Leaf 40. In two seasons the apple maggot was reported 

 by Mr. Hitchings as having prevented a proper grading of all varieties 

 in accordance with size.
