1910.] Injury to Foliage by Bordeaux Mixture. 109 



both "russeting" of the fruit and the yellowing and falling 

 of the leaves being noticed as the result of spraying in several 

 orchards or plantations in these districts. In other localities, 

 in plantations where an equal amount of Bordeaux mixture, 

 if not more, had been applied, no injury of any kind 

 could be observed. For instance, on a fruit farm near 

 Broadstairs all the apple trees, consisting of the following 

 varieties, were very thoroughly sprayed twice with Bordeaux 

 mixture made on the 4-4-50 formula : Golden Noblef, 

 Ecklinville, Cox's Orange Pippin, Worcester Pearmain, 

 Domino, Tom Puttf, Blenheim Orange, Benonif, Welling- 

 ton, Jacques Lebel, Cox's Pomonaf, Allington Pippinf , 

 Charles Ross, Royal Snowf , Glory of Englandf, Warner's 

 Kingf, Betty Geesonj-. No injury at all on the leaves or 

 fruit of any of these varieties could be observed, while the 

 fungicidal action of Bordeaux mixture had kept all the trees 

 practically free from "scab," the value of the mixture in this 

 respect being most marked in the case of those varieties 

 distinguished by a f, since these in the previous seasons had 

 borne very "scabby" crops. 



Again, a grower from the neighbourhood of Canter- 

 bury wrote last autumn of his experience as follows' : 

 "I have no fault to find with the result of my spraying 

 with Bordeaux mixture this season. Gladstone apples 

 shed some of their leaves about a fortnight after the 

 last spraying, but I am not at all certain if that was the 

 result of the spraying ; and Beauty of Bath and Cox's Orange 

 fruits were a trifle rough, but I think that that was more to 

 do with the weather than spraying. Bismarcks were most 

 certainly improved by the Bordeaux ; other varieties of apples 

 I sprayed were Worcester Pearmain, Lady Sudeley, Cox's 

 Pomona, Gascoigne's Scarlet, Lanes Prince Albert, Newton 

 Wonder, King Pippin, Allington Pippin, and a few other 

 varieties. All these showed no injury at all, and were all quite 

 free from ' scab,' except in one small patch where they were 

 not sprayed after the bloom had fallen, and there they showed 

 4 scab.' I have come to the conclusion that Bordeaux mix- 

 ture has done no injury to my apples this year, and that the 

 most important times to spray are just before the flower buds 

 open and about a week after the bloom has fallen."
