ENTOMOLOGY. 889 



Carnation diseases, G. F. Atkinson {American Florist, 24 {1905), No. 869, pp. 

 16-24, figs. 33). — This is reprinted from the American Florist of February 23, L893, 

 and gives extensive descriptive notes on a number of the more common and destruc- 

 tive diseases of carnations. 



Among those described arc the carnation rust ( Uromyces caryophyUinus), blighl or 

 spot of carnations due to Seploria dimUhi, carnation anthracnose caused by Volutella 

 sp., carnation rosette, and fairy ring spol caused by Heterosporium echimdatum; and 

 brief notes are given regarding the Botrytis disease, the injury caused by Clado- 

 sporium, etc., and where known suggestions for combating the diseases are made. 



A disease of carnations, (i. Poirault {Bui. Soc. Nat. Agr. France, 64 {1904), 

 No. 9, pp. 805-808). — Attention is called to a disease of carnations due to Fusarium 

 dianthi, and the varying susceptibility of different varieties is pointed out. 



The author has begun a series of experiments by which he hopes to increase the 

 resistance to disease by modifying the conditions of plant nutrition. He notes that 

 a variety of carnation very susceptible to disease was successfully grafted upon the 

 common soap wort {Saponaria officinalis) sad the carnation grew, bloomed profusely, 

 and remained free from disease throughout the season. 



The passion flower as a parasite, E. Pee-Laby {Rev. Gin. BoL, P; {1904), No. 

 /:>.', pp. 453-457, figs. 3). — The author reports the parasitic growth of Passiflora 

 coerulea on the roots of Ewmymus japonicus. 



The use of neutral copper acetate as a fungicide, E. Chuard and II. Faes 

 I citron. Agr. Canton Vaud, i: {1904), No. 2, pp. 601-608). — A preliminary report is 

 given of experiments with neutral copper acetate for preventing downy mildew of 

 grapes. 



The experiments were carried on at the viticultural station of Vaud in 1904, and 

 success followed the thorough use of the fungicide. Brief notes are given on the 

 results obtained by a number of grape growers with this fungicide, showing its prac- 

 ticability for use under ordinary conditions of care and application, etc. 



ENTOMOLOGY. 



Injurious insects of 1904, F. L. Washburn {Ann. /.'/>'. Mnir Eni. Minnesota, 9 

 {1904), pp- 197, pis. 2, figs. 177). — In this report the author presents a special 

 account of the Hessian fly, frit fly, peach-stem maggot, chinch bug, and the Medi- 

 terranean (lour moth. The last-named pest has caused great losses to millers through- 

 out Minnesota, and particular attention is devoted to a discussion of the remedies. 

 It appears from the author's experiments that the insect may he destroyed in any 

 sta^e by spraying with liquid CS,. It is not practical to destroy the eggs by the 

 fumes of CS 2 . A suitable method of spraying is described. Numerous other meth- 

 ods have been tried and found ineffective or less desirable. These include the use of 

 sulphur, steam, kerosene, ammonia, hydrocyanic-acid jjas, lime, tobacco, high tem- 

 perature, etc. 



A list is given of insects affecting raspberries, blackberries, currants, blueberries, 

 strawberries, grapes, melons, squashes, and cucumbers. A spraying apparatus 

 was devised on the basis of an outfit recommended by Professor Stedmau for 

 spraying nursery rows in combating leaf hoppers. The apparatus sprays -1 rows at 

 once. The insect was first observed early in July. At that time kerosene emulsion 

 was used at the rate of 1 part stock emulsion to 11! parts of water. This emulsion 

 killed the young insects hut not the adults. Later, a mechanical mixture of kero- 

 sene was used with better results. The author also discusses spraying machinery, 

 injury to apples from plum curculio, mottled willow borer, feeding habits of birds, 

 gophers, field mice, moles, woodchucks, rabbits, toads, etc., remedies for garden 

 insects, cottony maple scale, and the fumigation for violet gall fly, grain-plant 

 louse, etc.
