the pump is worked w.ith one hand and the other 

 hand guides the hose, through which the sulphur is 

 ejected. All the foliage and fruit should receive a 

 dusting with the sulphur, and where the foliage is 

 densest the heaviest dressing should be given. 



From 20 Ibs. to 25 Ibs. of sulphur per acre is 

 usually considered an effective dressing, although 

 on badly affected vines twice this quantity is often 

 used. In treating vines that have been badly 

 attacked, portion of the densest foliage should first 

 of all be cut away, to allow the sun's rays to enter 

 and destroy as much of the fungus as possible, 

 and a dressing with sulphur should then take place. 



A first dressing of sulphur, especially in places 

 much given to oidium, is often applied just as the 

 buds are bursting; a second dressing when the 

 foliage is about six inches long or when the vines 

 are in flower; and a third dressing later on, if neces- 

 sary. Each of these applications will, of course, 

 take more sulphur than the preceding one, as there 

 is more foliage to treat as the season advances. The 

 number of applications depends upon the nature of 

 the season, a wet and muggy spring being favour- 

 able to the spread of oidium, while in a spring that 

 is both hot and dry little, if any, oidium will 

 develop. 



ANTHRACNOSE, OR BLACK SPOT, IN VINES. 



This is another fungoid pest that attacks the vine 

 and which has done great damage at various times. 

 As water, either in the form of rain or dew, is abso- 

 lutely essential to the germination of the spores, 

 anthracnose is only prevalent in seasons having 

 frequent rains during spring and early summer. 

 The disease usually first makes it appearance in the 

 spring on the leaves and young wood of the vine, 

 where it is seen in the form of small dark or black 

 spots. As the disease developes, the spots eat holes
