MAINE AGRICULTURAL EXPERIMENT STATION. 



a sprayed plat; at the Rhode Island Station, in 1890 the increase 

 was 48 per cent., and several other stations report very favorable 

 results. 



Quite recently there has been put upon the market a fungi- 

 cide known commercially as "fungiroid." This article is man- 

 ufactured by Leggett & Brother, New York, and is said by them 

 to be a powdered Bordeaux mixture and a substitute for that 

 fungicide as ordinarily prepared. So far as I am aware, its qual- 

 ities have not been thoroughly tested. If fungiroid should 

 prove to be equally as effective as Bordeaux mixture, its advan- 

 tage over the latter would be its ease of application. This 

 applies especially in the treatment of low-growing plants. 



During the past season the subject was given some consider- 

 ation at this station. There were eighteen rows in the plat used 

 for this work. The first row was sprayed with Bordeaux mix- 

 ture; fungiroid was applied to the second, while the third was 

 left untreated to serve as a check, — and so on throughout the 

 plat — every third row in order receiving the treatment described 

 above, making six rows sprayed with Bordeaux mixture, six 

 treated with fungiroid and an equal number which received no 

 treatment. 



The first application of fungicides was made July 13; two 

 other applications were subsequently made at intervals of about 

 two weeks. 



The following table gives a summary of each of the six rows:

Referring to the column, "ratio of yield," it will be observed 

 that the total yield of the untreated rows was only 75 per cent, 

 that of the rows sprayed with Bordeaux mixture, or an increase 

 of 25 per cent, from the use of the Bordeaux; the total yield from 

 the rows treated with fungiroid was 83 per cent, that of the rows
