Twig Spot 



The well known grayish, purple bordered twig-spots seem to be due 

 to the fruit scab fungus. I found similar spores developing from them 

 last spring (See Duggar, Fungous Diseases). Stone and Monahan 

 mention a twig-spot due to a Monilia. 



Twig Blight, Staghead or Dieback 



The cause of death of branches is so varied as to be extremely con- 

 fusing. I may mention among fungi: Phoma persicce, Sclerotinia fruc- 

 tigena, Valsa lencostoma, Cortjxciini beyerinMi, Ncemospora crocea 

 also old age, poor soil conditions, yellows, spraying mixtures, oils in. 

 particular and probably some lime sulfur, cold weather, etc. 



Fungus and Insect Troubles 



Many diseases due to vegetable parasites have been pretty well 

 cleared up : such as crown gall, brown rot, leaf curl, bacterial leaf 

 spot, fruit scab, frosty mildew, California blight, powdery mildew, 

 rust, and fruit rot due to Gloeospormm Iceticolor and Aspergillus 

 glaucus. But among these and others many points in nomenclature,, 

 pathology and treatment are yet unsettled. 



It is hardly worth while to mention the large list of other fungi 

 given by Saccardo as occurring on peach but not mentioned in recent 

 pathological literature. But many of these occurring even on dead 

 tissues only may be stages of active parasites which are yet to be 

 worked out. 



The many disturbances due to insects and other animals, I shall 

 not mention, as they are out of my domain except to say that in 

 addition to the simple injuries they cause, definite diseased conditions 

 are due to nematodes, San Jose Scale, borers, curculio, root aphis, etc. 



LOCAL INSPECTION, PUBLIC SPRAYERS AND THE 

 OSAGE ORANGE HEDGE

Mr. President and fellow memhers: 



The title of these remarks would seem to indicate a rather elemen- 

 tary discussion to present to this Association, yet it seems to me that 

 we should not lose sight of these practical problems with which each-, 

 of us come in contact in the performance of our several duties. There-
