550 EXPERIMENT STATION RECORD. [Vol.37 



Work connected with insect and fungus pests and their control {Imp. 

 Dept. Agr. West Indies, Rpt. Agr. Dept. Montserrat, 1915-16, pp. 23-26).— Be- 

 sides notes on cotton stainers, an account is given of attempts to control pea- 

 nut leaf rust {TJredo sp.), which was accomplished with Bordeaux mixture; of 

 a serious and spreading wilt of pineapple, involving root decay ; and of two 

 diseases of papaya, one of which appeared on the leaves in association with 

 Asperisporium caricce in an unsuitable situation, the other and more important 

 one attacking stems and fruit and resembling considerably a disease reported 

 from Barbados as produced on stems, leaves, leaf stalks, and fruits by a 

 species of Colletotrichum. 



Reports of the botanical laboratory and laboratory for plant diseases, L 

 liiNSBAUEB, F. ZwEiGELT, and H. ZuDEKELL (Piogramm u. Jahresber, K. K. Hoh. 

 Lehranst. Wein u. Obsthau Klosterneuhurg, 191^-15, pp. 91-101; 1915-16. pp. 

 117-130).— Continuing previous work (E. S. R., 33, p. 444), the first of these 

 two reports, along with insect enemies and other matters, deals with Fusi- 

 cladium, Penicillium, Gymnosporangium sabince, Mycosphcerella scutina, Puc- 

 cinia pruni-spinosw, and leaf curl as related to orchard plants ; Sphwrutheca 

 mors-uvce on gooseberry; Plasmopara vitieola on grape; Plasmodiophora bras- 

 sicce, Sclerotinia libertiana, Colletotrichum lindemuthianum, Bremia lac- 

 tucce, and Peronospora effusa on vegetables ; Asteroma rosce and Oldium 

 cuonymi japonici on ornamental plants ; Erysiphe tortilis, Cceoma cuonymi, 

 Lophodermium macrosporum, L. pinastri, P. effusa, Ustilago tragopogonis, and 

 Ramularia violce on wild-growing plants. 



The second report also gives data regarding Septoria piricola, Cephalothe- 

 cium roseum, Phytophthora cactorum, Exoascus bullatus, and E. deformans on 

 fruit trees; Boytrytis and Oldium on grape; Pseudotnonas phaseoli, P. campes- 

 iris, Puccinia chondrillcE, and P. glumarum on field or garden plants; (lyin- 

 nosporangiiim clavariwforme, Glocosporium tilia-, G. nervisequum, and Phrag- 

 midium subcorticiutn on various ornamentals. 



Some new or rare plant diseases, L. Montemabtini {Riv. Patol. Vcg., 7 

 {1915), No. 8-9, pp. 225-2S7; 8 {1916), No. 8-9, pp. 177-185).— In the first of 

 these reports, continuing previous work (E. S. R., 30, p. 349), the author notes 

 a leaf scorch of Syringa vulgaris associated with Cladosporiuvi syringa n. sp. ; 

 one of Anthurium with Chcetodiplodia anthurii n. sp., Glomerclla avthurii n. sp., 

 and Colletotrichum anthurii; a leaf spot of Corylus avellana with Ccrcospora 

 corijli n. sp. ; of Quercus scssilifiora with Septoria sp. and Phyllosticta itnlica 

 n. sp. ; of Camellia japonica with Alternarin camellice; at Crataegus with 

 Hadrotrichum populi ; a leaf dieback of yucca with Cylindrosporium yuccce 

 n. sp. ; a leaf perforation of peony with Coniothyrium pceoniae n. sp. ; and a 

 Cicinnobolus. very similar to C. ccsatii evonymi noted in France by Vulllemin 

 (E. S. R., 24, p. 352), attacking OTdium on oaks. 



In the second report, the author notes a bacteriosis of chestnut leaves; a 

 leaf spot of Tilia ascribed to a fungus which is considered a new variety, 

 Phyllosticta bacteroides minima; a fruit disease of pomegranate due to Ceutho- 

 spora punicw; a leaf shot-hole and laceration of Acanthus connected with a 

 fungus described as a new variety, Septoria acanthi romana ; a leaf curl of 

 cherry associated with Exoascus cerasi; a leaf spot of Crataegus oxyacautha 

 associated with P. bacillaris n. sp., supposedly the pycnidial stage of Tcnturia 

 cratcegi; and a cucurbit leaf spot associated with several fungi named as prob- 

 ably saprophytic, with Ccrcospora cucurbitce, P. cucurbitacearum, Ascochyta 

 sp., and the new species S. cucurbitce and Leptosphwria cucurbitce, also sup- 

 posed to be parasitic.
