The Florists' Review 



June 29, 1916. 



centered, particularly in the states of 

 Michigan, Wisconsin, Indiana, Illinois 

 and Minnesota. In greenhouses, the dis- 

 ease was reported from Illinois as early 

 as 1908, and is known to occur to a 

 more or less limited extent in New 

 York, OLouisiana, Pennsylvania and 

 other states. In the greenhouse the 

 disease is quite similar in its principal 

 symptoms to those found in the field, 

 the principal differences being that the 

 disease appears to be more virulent, 

 many of the plants wilting and dying. 



The mosaic disease has recently been 

 studied by the Michigan Experiment 

 Station in cooperation with the Bureau 

 of Plant Industry, U. S. Department 

 of Agriculture, and by the University 

 of Bochester in cooperation with the 

 Cornell University Agricultural Experi- 

 ment Station, and its nature discovered. 

 It belongs to the same class as the 

 other mosaic diseases of tobacco, po- 

 tato, tomato, pokeweed and other 

 plants, which have been known for 

 some time. The exact cause of this 

 class of troubles has not been discov- 

 ered, but it is considered to be what is 

 known as a filterable virus, an agent of 

 infection which is so finely divided 

 that it will pass through a porcelain 

 filter and" 'still retain its ability to re- 

 produce the disease when injected into 

 healthy plants. It has been definitely 

 proven that plant lice transferred from 

 diseased to healthy plants will carry 

 the disease. It if also practically cer- 

 tain that the disease is spread by pick- 

 ers when harvesthig tifl^cucumbers. 



Judging from the nafilS of the dis- 

 ease and from the preliminary experi- 

 ments thus far carried out, the remedial 

 measures indicated by our present 

 knowledge are (1) the eradication or 

 ^^ontrol of insect pests which act as 

 carriers of the disease, and (2) the 

 application of sanitary measures to 

 eliminate the sources of infection. 



CUCUMBEBS NOT SETTING. 



I have a house planted to cucumbers, 

 which are failing to develop any fruit. 

 They bloom in great profusion, but the 

 small cucumbers turn yellow and dis- 

 appear. Do cucumbers in a house need 

 any artificial fertilizing! If so, how 

 should this be done? C. O. G. — Mo. 



Yes, cucumbers need artificial pol- 

 lination to insure a good crop. Of 

 course at this season, when insects are 

 abundant, it is not so necessary to pol- 

 linate as it is earlier. The best plan, 

 and one adopted by many of the most 

 successful cucumber specialists, is to 

 keep hives of bees in the houses. This 

 will insure a heavy set. Try to secure 

 one or two hives. Until they arrive, 

 give the plants a shake early in the 

 afternoon each day to distribute the 

 pollen. C. W.
