Gooseberry Growing. 



[Sept., 



Careless, and Crown Bob. Yellow Eough (Golden Drop) cannot 

 safely be sprayed with lime sulphur at all. 'See Leaflet No. 

 195.) 



Gooseberry Satvfly (Nematus ribesii, Curtis). — The larvae of 

 this sawfly are frequently very troublesome, attacking the leaves 

 and young fruit which are sometimes entirely cleared off. They 

 are, however, easily checked by thorough spraying with arsenate 

 of lead at the rate of 4 lb. to 100 gallons of water. This spray 

 must not be used within six weeks before the fruit is gathered. 

 For other washes see Leaflet No. 12. 



Aphides. — Various species may — when conditions are favour- 

 able — increase to such an extent as to damage the bushes 

 seriously and prejudice the crop. They may be controlled by 

 very early spraying before the curling of the leaves prevents 

 them being wetted. If the leaves have been allowed to become 

 badly curled, the infested tips should be picked off and burnt. 

 {See also Leaflets Nos. 68 and 104.) 



Red Spider (Bryobia ribis). — This is really a mite, scarcely 

 visible to the naked eye, and may prove very troublesome in 

 droughty summers. Its presence is usually first detected by the 

 characteristic yellow and sickly appearance of the leaves. It 

 may be eradicated early by application of oil emulsion, liver of 

 sulphur and various proprietary washes.
