extent but only practicable in 

 a few cases. Sulphide of 

 Carbon injected among the 

 roots has proved successful to 

 a certain extent but it is an 

 expensive remedy. The most 

 effective way of dealing with 

 the pest appears to be the 

 destruction of affected plants 

 as soon as the insect is detected. 

 Should the pest make its 

 appearance in any locality it 

 will be advisable that the 

 ordinary varieties be grafted 

 upon what are known as 

 resistant stocks. These are 

 supplied by several American 

 species which are being used 

 very successfully in European 

 vineyards. Full information 

 respecting these kinds will be 

 found under the heading of 

 American Grapes.

INJURIOUS FUNGI. 



There are various kinds of 

 Fungi that are troublesome 

 to Grape cultivators and several 

 are unfortunately too well 

 known. As regards others, 

 however, our knowledge is less 

 perfect and there is a wide 

 field for further investigation. 

 Grape Vines are often affected 

 by obscure diseases and doubt- 

 less these in the majority of 

 cases are due to the action of 

 Fungi. In doubtful cases culti- 

 vators will do well to en- 

 deavour to ascertain, as far as 

 may be practicable, the cause 

 of the trouble and to promptly 

 apply the most effective 

 remedies. The following list 

 embraces the more prominent 

 and troublesome Fungi, so far 

 as they are known :
