and are preferable for platform and power pumps. " Bordeaux " 

 type nozzles, throwing a fan-shaped spray, are excellent for any 

 kind of spraying if adjusted properly. Impurities in the spray 

 water often partially decompose insecticides and cause them to 

 injure plants. 



IS CODLIN MOTH A DANGER, OR IS IT NOT ? 



\\ V remember the time, twenty years ago, this moth was 

 unknown throughout South Africa. We believe it was intro- 

 duced to Cape Town with apples from Madeira about eighteen 

 years ago, and rapidly spread throughout the Western Province 

 where its ravages in the early days were very serious. Of late 

 years, mainly through the introduction of arsenate of lead as a 

 spray, instead of the previously used Paris green, and the recog- 

 nition by all growers that to secure sound fruit spraying was 

 vital, resulting in the fact of practically every orchard of these 

 fruits being sprayed, the pest has become much less serious. We 

 can safely say fruit growers in the West fear it no longer. Most 

 of them for some time now have looked upon spraying for Codlin 

 as part of ordinary orchard practice. 



However, in other parts of the Union, where Codlin has 

 only been present for two or three years, particularly in the Free 

 State, where farmers do not know how to cope with it, this dis- 

 ease has unquestionably frightened planters who had hoped to 

 have made the growing of apples and pears a profitable venture. 

 We will say at once that all the great apple and pear growing 

 countries of the world have had this pest for years and years, 

 and in the face of it the great American. Canadian and Austra- 

 lian International Apple Trade has been built up running now 

 into a value of many millions sterling, and increasing in volume 

 and value each year. We are satisfied there is no reason why 

 we cannot on the high veldt under the conditions there found, 

 'qually successfully establish a great Apple Export Industry. 

 Readers under these conditions will say " Oh, yes, it is easy to 

 talk of success in the Western Province ; your conditions are so 

 different and it is so easy to combat the pest there by spraying, 

 but we* have to spray in the rain, and it is a failure." In support 

 of our contention we would like to draw freely on a late report 

 "f Mr. F. J. Harper. Manager of Platkop Fruit Farm, Clocolan, 

 *oo apple and pear trees under his charge. He writes 

 to the Union Horticulturist on the mth April last: 



" I have received many complaints this year that the 



spraying has been of no avail against Codlin; in fact all my 



neighbours are fed up and it looks as if some of them would 



uck up the idea of fruit growing for profit. It ap-
