thcj apple powdery mildew may safely be 

 counted upon to be present on the trees 

 in injurious amounts every year when 

 once well established. In other words, 

 weather conditions are seldom suffici- 

 ently unfavorable to the growth of the 

 fungus to amount to satisfactory control. 



So far as local experience goes, no 

 variety nf apple is immune to the mil- 

 dew, but some are more injured by its ■* 

 attacks than others. Those varieties of 

 delicate growth under the environment 

 in question are more susceptible than 

 the hardj" ones. It may very frequently 

 develop that a variety suffering little iii 

 one locality may be badly attacked in 

 another. In the Pajaro Valley, a list of 

 ^-arieties. including the Newtown Pippin, 

 Smiths Cider, Missouri Pippin, Spitzen- 

 berg, Gravenstein and Yellow Bellflower, 

 have in general been found to be espe- 

 cally susceptible. Under similar condi- 

 tions the Red Pearmain, White Winter 

 Pearmain. Red Astracan, Rhode Island 

 Greening and Langford are less badly 

 attacked. However, these varieties can- 

 not be rigidly placed in the above classi- 

 fication, for even in the limited area of 

 the valley notable exceptions occur. Fur- 

 ther back from the coast, and in the 

 Santa Cruz Mountains, Newtown and 

 Bellflowers are quite free from the dis- 

 ease, but Spitzenbergs and Jonathans are 

 badly attacked. 



Mildew infection and total absence 

 from it makes a marked difiference in the 

 general appearance of the tree, and it 

 often happens that an apple growing 

 under mildew conditions will hardly be 

 recognized as the same variety when 

 found in a section free from the disease. 



Little or no effort had been made to
