[Feb., 



series of chemicals did not give satisfaction in every respect. 

 Dormant spores were found (1920) to retain their vitality in the 

 soil for at least 10 years. 



Norway. — In 1914, Wart Disease appeared in the Kristiansand 

 District in two localities near Grimsmoe, and by order of the 

 Department of Agriculture the infected plants were immediately 

 uprooted and the soil disinfected with a 1 per cent, formalin 

 solution, while it was strictly forbidden to plant potatoes or 

 tomatoes in the infected zone for at least 6 years. In spite of 

 these precautions, the disease spread in 1915 and was reported 

 from 27 other localities. The Government spared no effort to 

 suppress the pest. It gave special facilities for the purchase of 

 disinfectants, it held lectures and distributed pamphlets, and, 

 finally, it issued the Decree of 8th September, 1916, which, 

 besides regulating the control of the disease, imposed penalties 

 on those farmers who. instead of co-operating with the State, 

 attempted to evade the law. 



Sweden. — The disease has been reported by Eriksson as 

 occurring near Stockholm. 



Austria and Russian-Poland. — It was stated in 1920 that Wart 

 Disease had not appeared in Austria, but was established in 

 Russian-Poland. 



France. — In " Annales du Service Epiphytics," Vol. IV, 

 1915, it is stated that Wart Disease does not occur in France. 

 By a Decree of 19th December, 1910, the import of potatoes 

 affected with " Black Scab " is prohibited. 



Belgium. — Apparently the disease has not yet been recorded 

 officially in Belgium, but there is every possibility of its existence 

 in small gardens, as an officer of the Ministry whilst serving in 

 Belgium during the War noted its presence near Ypres. There 

 are no regulations dealing with it. but the nearness of centres of 

 infection induced the Authorities to warn farmers of the serious 

 nature of the disease. 



Luxembourg. — Mr. Bintner, of the Agricultural Department 

 of Luxembourg, told an official of the Ministry of the widespread 

 nature of Wart Disease there. 



There appear to be no definite records of its appearance in other 

 European countries, nor indeed in other parts of the world save 

 in the U.S.A. where it was introduced from Europe in 1912, 

 but remained unrecorded until 1918.
