546 American Gooseberry Mildew. [dec, 



(2) To plant such gooseberry bushes or stocks as they may 

 buy or acquire from other premises than their own in a special 

 part of their nursery or garden at some distance from other 

 gooseberry bushes. 



(3) To keep a careful watch on all gooseberry plants for 

 any signs of mildew, and to report any appearance suggestive 

 of the disease to the Secretary of the Board of Agriculture 

 and Fisheries, 4, Whitehall Place, London, S.W., immediately 

 it is detected. In the case of any county or district to which 

 a Gooseberry Mildew Order of the Board applies,* notice of 

 the disease, or of its suspected appearance, must at once be 

 given to the local authority instead of the Board. 



(4) To assist the Board in discovering any unreported 

 cases of the disease. 



Prevention. — With the object of preventing the disease from 

 gaining a hold in their plantations, all gooseberry growers who 

 live in districts in which the disease has been discovered should 

 frequently make a careful inspection of their bushes, and treat 

 any suspected bushes as described below ; but whether 

 suspected bashes are met with or not growers should spray at 

 regular intervals throughout the summer and autumn. 



Unfortunately the winter stage of the fungus is so well 

 protected that none of the sprays in ordinary use affect it, and 

 there is very little chance that any kind of spray would prove 

 effective ; but throughout the whole summer stage, which lasts 

 about as long as the bushes are in leaf, sprays may be used. 

 They are then most valuable both in destroying the fungus and 

 in rendering bushes less liable to infection by the spores ; and 

 although spraying by itself cannot be relied upon to cure an 

 outbreak, it is a measure which should never be neglected. 



In spring, from a fortnight to three weeks before the young- 

 leaves appear, the bushes should be thoroughly sprayed with 

 Bordeaux mixture. f For use as soon as the buds open, and while 



* Up to the time of going to press, the Board have made American Gooseberry 

 Mildew Orders which apply to the Counties of Gloucester, Worcester, Isle of Ely, 

 Lincoln (parts of Holland), Norfolk, Warwick, Derby, Cambridge, Leicester, Notting- 

 ham, Huntingdon and Hereford. 



f To prepare Bordeaux mixture, 20 lb. of sulphate of copper (98 per cent, 

 purity) should be dissolved in cold water in a wooden vessel, and 10 lb of pure, fresh 

 quicklime should be slaked in a separate vessel. Gritty " thin " lime, or lime with a 

 slaggy surface, should be avoided. Enough water should be poured on it to cause it 

 to crumble, and the operator should not hurry the process, but wait for it to occur.
