Joitriial (if Agriculture, Victoria. [15 Oct., 1919. 



It was viTV poor in the cast of Sultana and most table grapes, includ- 

 ing Ohanez, Kosaki (Waltham Cross), and Valensi (Belas Blanc), i&c. 

 The above refers to the secondary crop of fruit. In every case good 

 pruning wood was obtained. 



The damage wrought by hail is often (luite simirar to that caused \>y 

 frost, and identical treatment will give equally satisfactory results. 

 This is especially so in the case of a severe hailstorm early in October, 

 such as would destroy all embryo hunches. The crop has gone, but tin- 

 secondary latent bud's are still available, and can be forced into growth 

 by the radical suppression (pruning or disbudding) of the hail-damaged 

 shoots as described above for vines injured by frost. 



Hail may fall at any time during the growth of the vine; late hail 

 storms often constitute difficult problems, since radical pruning is nr»

longer suitable. Treatment may usually be limited to trimming and 

 shortening back the injured shoots. Sometimes, indeed, it is best to take 

 no action at all. 



After a hail storm it is usually well to defer action for a couple of 

 days until the full extent of the injury ean be gauged. The breakages 

 caused by hail are at once apparent, but the bruises show up more slowly; 

 these may be so severe and deep-seated as to justify the removal of shoots 

 which shortly after the storm may seem to have been only slightly 

 damaged. 



Vines damaged by flood during the growing season may also present 

 very similar cases to injury by frost and hail, and need treatment on the 

 lines described above. Whenever the fruit and upper portion of the 

 primary shoots hqs been destroyed the best i)oliey will be their complete 

 removal in order to foi'ce the development of latent secondary buds. ■
