It was perhaps those varieties worst attacked by the mildew that 

 dropped their leaves worst as a rule, but there were exceptions, as 

 Table III. shows. 



The progress of the disease was not very marked for a little time 

 after the spraying, partly because there was nothing to attack in 

 some cases, but as soon as growth commenced again on the defoliated 

 shoots, the mildew again spread rapidly. A third spraying was carried 

 out with lime-sulphur wash, having a specific gravity of 1*005, 

 and again the effect upon the foliage was most marked. Table II. 

 shows the varieties which lost their leaves under this spraying.

Note. — Some of the varieties not named were still defoliated from 

 the liver of sulphur spraying (compare Tables I. and III.) 



The spraying appeared to check the mildew for a short time, but 

 not to kill the fungus completely, so that it subsequently recovered 

 and spread still further. 



Table III. shows a list of varieties which were not affected by 

 the spraying either with the liver of sulphur or lime-sulphur sprays. 

 It also shows the varieties in the collection which were least badly 

 attacked by the mildew. No variety seems to have escaped attack 

 completely.
