54 The Spraying of Plants. 



the proper remedies for its control were soon found, and as the 

 disease became more widely distributed, the best remedies dis- 

 covered in the region first attacked were adopted by the newly 

 infected districts, with practically no modification. It has thus 

 been brought about that the Bordeaux mixture, the ammoniacal 

 solution of copper carbonate, the eau celeste, and solutions of 

 copper sulphate, have become standard remedies in those coun- 

 tries which have been last to suffer from the imported American 

 diseases. These fungicides are generally applied as in France. 

 In Germany, however, care is taken that no applications are made 

 during the blossoming period, and there seem to be good reasons 

 for the practice. Later applications are made often enough to 

 prevent injury from fungi, the numbers varying from two to 

 five, three being more commonly made. Anthracnose of the 

 vine is treated as in France, and appears to be held under con- 

 trol without much difficulty. 



Confidence has thus again been restored where not more than 

 ten years ago there prevailed the greatest anxiety regarding 

 the future of the grape industry. 



IV. IN ENGLAND. 



The English have been slow to adopt new remedies for plant 

 diseases. While French growers were struggling to overcome the 

 downy mildew of the grape and the rot of potatoes, British gar- 

 deners were practically helpless in dealing with them. Even after 

 success had rewarded their southern neighbors, the new methods 

 were but slowly adopted in England. The horticultural jour- 

 nals of that country, on the contrary, were quick to see the value 

 of the work that was being done, and the French recommenda- 

 tions were repeatedly published. The first account appears to 

 have been given in The Gardeners' Chronicled This was a trans- 

 lation of a report made by Prillieux, inspector-general of agricul- 

 tural education, to the minister of agriculture of France, regarding 

 the value of a mixture of copper sulphate and lime against the 

 mildew of the vine. The account contains a brief history of the 

 work done in the Medoc, and also mentions the names of the 

 men who were most prominently connected with it.
