 Disease Order of 1919 may be useful. 



The Policy relating to the Planting of First Early Varieties 

 in Wart Disease Infected Areas. — Owing to present lack of 

 suitable first early varieties immune from wart disease, the 

 Ministry does not, for the time being, propose to restrict the 

 planting of first early varieties in Infected Areas to those which 

 are immune, and has made the following concession: — 



On land situated within an Infected Area, but on which 



disease has not actually occurred, occupiers may plant the 



following first early varieties : — 



Duke of York (or Midlothian Early or Victory).; May Queen ; Ninety- 

 fold ; Epicure ; Sharpe's Express; Ringleader; Eclipse; Sir John 

 Llewellyn ; and Puritan ; and any others that may be hereafter 

 approved by the Ministry for the purpose. 

 If " seed " for this purpose is required to be mtroduced into 

 an Infected Area, a licence from the ]Ministry will be necessary. 



This policy will remain firm until jNIay, 1924. All potatoes 

 grown under this concession must be used or consumed withia 

 Infected Areas. 



The Wart Disease Order. — The main requirements of this 

 Order are as follows: — 



(1) If disease appears, or re-appears, on any land, or 

 is found in potatoes in any kind of store, the occupier of 

 the land or the owner of potatoes must at once notify the 

 Ministry. 



(2) Only seed of immune varieties, certified as such by the 

 Ministry, or otherwise specially licensed by the Ministry, must 

 be planted in an Infected Area, or brought into an Infected 

 Area for planting (except the variation referred to above as 

 to First Early varieties). 



(3) Seed raised in an Infected Area must not be sold 

 for planting in land w^hich is not within an Infected Area. 



(4) Tubers visibly affected w^ith wart disease must not be 

 sold or offered for sale for any purpose.
