killed the main part of the tops of the trees, the trunks and larger 

 limbs only showing signs of life. Many of the trees died outright 

 from this attack. It has been doing considerable damage since that 

 date, mainly to trees planted in the parks and streets of the larger 

 cities, such as Richmond, Norfolk, Roanoke, Lynchburg, Staunton, etc. 



This winter a fungus growth resembling Sphaerostilhe coccophila 

 has been observed quite abundant, attacking this scale insect on some 

 of the trees in Lynchburg. The Park Commission of Lynchburg has 

 been spraying this winter with soluble oil to control this pest. It is 

 his opinion, however, that the infested trees should be gradually re- 

 moved and replaced by some hardier and more desirable sorts, — some 

 that are not so subject to insect attack. 



Mr. J. B. Smith mentioned having found the same fungus in a sec- 

 tion of New Jersey, where it had never been introduced artificially, 

 and expressed the opinion that it is of little value in that State. 



]\Ir. R. I. Smith described the manner in which he had introduced 

 this disease into several peach orchards in Georgia. He stated that 

 he first visited a large orchard in Komoko, Florida, in which the San 

 Jose scale had been largely destroyed, presumably by this disease, 

 which had been introduced the year previous. He found quantities 

 of the fungus on oak trees in and near Atlanta, Georgia, and intro- 

 duced it into several orchards in the middle and southern parts of the 

 State. This was accomplished by taking pieces of oak bark, which 

 were infested with Aspidiotus ohscurus, the latter being infected by 

 Sphaerostilhe coccophila, and attaching this bark to peach trees in- 

 fested with the San Jose scale. From three to six pieces were tied in 

 each tree. This work was done during June and July, 1907, and an 

 examination of one of the orchards in September showed that the 

 fungus had established itself to a slight extent on the San Jose scale. 

 In some cases fungus was found two or three feet from the specimen 

 which had been tied to the limb, and in one instance it was found on 

 an adjoining tree, upon which no fungus had been artificially intro- 

 duced. Mr. Smith also mentioned finding Sphaerostilhe in the middle 

 of the Hale orchard at Fort Valley, Georgia, while the nearest source 

 of fungus on oak trees was nearly a half mile distant. He recalled 

 finding this fungus very abundant on oak trees infested with the 

 ohscurus scale in the city of Atlanta, and had found maple trees in 

 the same locality badly infested and dying from the attack of this 

 scale, but none of the fungus was present on these trees. He be- 

 lieved that the work of introducing Sphaerostilhe into San Jose scale 

 infested orchards should be given further attention and careful in- 

 vestigation.
