1 68 FRUIT FARMING 



Sulphur, J oz. to i gallon of water. In bad attacks of 

 this disease the shoots are much dwarfed and distorted, 

 and the fruit occasionally covered with rusty patches. 

 Preventative measures are as usual the best, and by 

 keeping the trees well pruned, cutting out weak 

 shoots and growing the trees in an open and dry 

 position, the soil being well cultivated, the grower 

 should keep clear of the disease altogether. It appears 

 most generally where Gooseberries are grown under 

 tall trees which exclude the sun, and notably it appears 

 during a wet time and muggy weather in September. 

 As it appears on the points of the shoots, they can 

 be cut off and burnt; but this is now a disease which 

 has to be notified to local County Councils by law. 



NECTARINES AND PEACHES. 



APHIS. See under Apple. 



LEAF CURL OR BLISTER IN PEACHES AND NEC- 

 TARINES. This is caused by fungus, which appears 

 when the young growth is checked by cold winds ; 

 the affected leaves should be removed and burnt. 

 The twisted leaves form convenient nesting places for 

 aphides, which should be kept down by the washes 

 already named. On the return of warm weather the 

 Trees will put forth healthy shoots, and every care 

 should be taken to encourage the strong growths. 

 Foliage under glass is aflected when cold draughts 

 play on it, root pruning one side of the roots yearly 

 checks it. We offer a certain remedy, called Medela 

 (Latin "a cure"), invented by our Mr. F. Buss, which 

 should first be used in February, then again when 

 the buds swell, and again before the buds fully open 

 (No. 1 8).
