846 EXPERIMENT STATION RECORD. [Vol. 37 



Evidence of the overwintering of Cronartium ribicola, P. Spaulding (Aba. 

 in Phytopathology, 7 (1911), No. 1, p. 58). — The author reports that currants are 

 fi'equently infected with C. ribicola one summer but not the next and, further, 

 that cooperative experiments in which 500 heavily infected black currants were 

 used resulted in no disease. The author states that he has had under observa- 

 tion for seven years in greenhouses in Washington, D. C, hundreds of Ribes 

 plants used in inoculation experiments, and in no case has the disease ever ap- 

 peared the next season until artificial inoculations have been made. It is 

 claimed that infection of petioles is not so rare as has been supposed, that no 

 evidence of bud infection by way of the petiole has been obtained, and that 

 direct examination of buds of infected plants has failed to show the presence 

 of the fungus. 



The pine blister, B. H. Paut, (N. Y. State Comerv. Com. Bid. 15 (1916), pp. 

 18, pi. 1, figs. S).— This is a r§sum6 of the proceedings of a conference held by 

 the committee for the suppression of pine blister in North America at Albany, 

 N. Y., November 20 and 21, 1916. A general account is given of the character- 

 istics and importance of the disease in the United States and Canada, also the 

 result of preliminary work showing the distribution of the disease as known to 

 date, with recommendations and other information looking toward its control. 



The control of white pine blister rust in small areas, W. H. Rankin (.46s. 

 in Phytopathology, 7 (1917), No. 1, p. 58). — A brief account is given of experi- 

 ments in control of white pine blister rust on 85 forest plantings in New York 

 State. Diseased or suspicious trees and all species of Ribes were removed 

 within 500 ft. of the plantings, and the results obtained seem to indicate that 

 this treatment prevented the appearance of Cronartium ribicola in these areas. 



Some new or little known hosts for wood-destroying' fungi, A. S. Rhoads 

 (Phytopathology, 7 (1917), No. 1, pp. J,6-lt8).—\ list is given of host species of 

 16 wood-destroying fungi, the species being believed to be new or at least little 

 known hosts for these fungi, which have not iK^en previously reportetl upon 

 them.

Report of the entomologist of the Arizona Commission of Agriculture and 

 Horticulture for the year ended June 30. 1916, A. W. Morkiix (Ariz. Com. 

 Agr. and Hort. Ann. Rpt., 8 (1916), pp. 11-57, pis. S, figs. /7).— The first part 

 of this report (pp. 11-30) deals with in.s'pection work, the alfalfa weevil pro- 

 tective service, insect control and eradication, etc. Part 2 (pp. 31—49) con- 

 sists of notes on the more important insects of the year, and part 3 (pp. 51-57) 

 takes up three plant diseases In 191G, namely, citrus gummosis, citrus scaly 

 bark, and pear blight. 



The more important insects of the year are considered under the headings 

 of pests t>f deciduous fruits, small fruits, and vines ; citrus and olive pests ; 

 pe.sts of field and forage crops; vegetable crop pests; and cotton i)ests. During 

 the year four species of insects and one species of red spider, not previously
