' con POST — a f'ARTA aoiL amo I paut manurc. 



Chart With Which Dr. Galloway Illustrated the Carnation Experiments of the Department of Agriculture. 



decomposed organic manure — something 

 which could be secured anywhere in the 

 country. He said, however, that experi- 

 ments of this kind, to be conclusive, must 

 be carried on for a number of years in 

 various places. He cautioned the grow- 

 ers to go slowly on commercial fertilizers 

 and to put their faith and work into 

 good composts. 



He explained the work the Department 

 had been doing in its study of hereditary 

 tendencies in plants in so far as these 

 tendencies may affect continuous vigor, 

 kealthfulness and yield. He said the 

 question of whether there is true bud 

 variation was still an open one, but that 

 at the same time he did not think the 

 importance and value of careful and 

 rigid selection of stock could be ques- 

 tioned. This the Department has been 

 doing, and he stated it was its intention 

 to continue this selective work for several 

 years, until the effects could be fully 

 demonstrated. 



The speaker mentioned the work the 

 Department had been doing in the pro- 

 duction of new types by crossing, and 

 referred to some of the crosses that 

 niight be seen in the greenhouses. 



He said that Prof. Norton, whose talk 

 was to follow his, would explain in de- 

 tail the fifth line of work, namely, a 

 study of fundamental questions of 

 breeding, which work, he stated, had 

 been carried on by Prof. Norton before 

 leaving the Department. 



Diseases of Carnations. 



Dr. Galloway now took up the sixth 

 lin^ of work which the Department had 

 been conducting, namely, an investiga- 

 Hon of the diseases of carnations. 

 Among the diseases studied was the wet 

 stem-rot, due to rhizoctonia, which he 

 stated continues to be one of the most 

 ''furious diseases with which the growers 



have to contend, but that it could be 

 controlled by growing the plants in well 

 drained and well aerated soil containing 

 plenty of lime, and by avoiding mechan- 

 ical injury to the plants. He also men- 

 tioned the dry stem-rot, a disease caused 

 by fusarium, one of the wilt fungi, and 

 stated that the only remedy for this dis- 

 ease was the use of sterilized soil and 

 the liberal use of acid phosphate. 



Two other diseases to which attention 

 was called were the macrosporium spot, 

 which he said could be prevented by 

 spraying with Bordeaux mixture, and the 

 bacterial spot, a disease occurring only 

 in wet seasons on the softer-leaved varie- 

 ties. This disease, he stated, might be 

 controlled by light syringing with a mix- 

 ture of two parts commercial formalde- 

 hyde to 1,000 parts water. 



Dr. Galloway closed his remarks by 

 assuring the society that the Department 

 was always at its service, and with an in- 

 vitation to its members to visit the De- 

 partment greenhouses. 



BUD ROT OF CARNATIONS. 



Bulletin No. 103 of the Agricultural 

 Experiment Station of Nebraska contains 

 "The Bud Rot of Carnations," by F, 

 D. Heald, and "A Mite Accompanying 

 the Bud Rot of Carnations," by R. H, 

 Wolcott. 



"During the last few years a trouble- 

 some and destructive disease of carna- 

 tions has been prevalent in a number 

 of the greenhouses of the state. The 

 disease affects the buds in various stages 

 of maturity and produces a rotting of 

 the petals and other flower parts, at 

 least the parts enclosed by the calyx, 

 thus interfering with the normal open- 

 ing of the flower. The disease has there- 

 fore been termed the bud rot of the 

 carnation," says Dr. Heald. 



' ' The bud rot of carnations was first 



reported in 1905 by Dr. Wolcott from 

 specimens received from a greenhouse 

 at Beatrice, Neb. He attributed the 

 trouble entirely to a mite which was 

 constantly present in the affected buds. 

 The mite was briefly described as be- 

 longing to a new and hitherto unde- 

 scribed species and possibly a new 

 genus. At this time the fungus origin 

 of the trouble was not suspected.. Later 

 in the same year the same trouble was 

 reported to the writer and an investiga- 

 tion was begun. The first examination 

 showed the mites, and in addition the 

 rotting petals were found to be per- 

 vaded by the mycelium of a fungus. 

 An examination of the rotting buds led 

 to the belief that the mites were only 

 secondary, and that the fungus was the 

 primary factor in causing the disease. 

 "The bud rot does not seriously af- 

 fect the plant, as the fungus is confined 

 entirely to the buds. It has never been 

 found growing on other parts. The in- 

 jury is due, then, solely to the fact that 

 affected buds produce deformed flow- 

 ers or entirely fail to develop. Flowers 

 which upon superficial examination ap- 

 pear only slightly malformed are badly 

 rotted within the calyx and soon wither 

 and die. This fact has been especially 

 noted in the discussion of the symptoms. 

 If the buds have remained without in- 

 fection until the calyx has opened suf- 

 ficiently to expose the tips of the petals, 

 subsequent infection will cause but slight 

 injury, as the fungus does not have time 

 to develop before the flower has ex- 

 panded. In houses where the trouble is 

 severe the buds become infected when 

 quite small, probably when not more 

 than one-half inch long. When infec- 

 tion took place at this early stage many 

 of the buds rotted before they had time 

 to open, or if they did open at all pro- 

 duced very imperfect and worthless
