Where the peach aphis causes tlama e it may be controlled by spraying 

 with a nicotine solution. Two to three sprayings during the growing period 

 will be found necessary if the aphides are numerous. 



San Jose scale is another serious enemy of the peach-grower, and should! 

 immediately be dealt with upon detection. It may be controlled by spraying 

 (1) with resin and soda (during the summer, after the fruit has been removed),, 

 and (2) with miscible oils or lime-sulphur. Either of the latter may be used 

 in the winter. If using lime-sulphur spray, a second application before the 

 buds burst will be found most beneficial. 



Fumigation with hydrocyanic gas is another method of control. Fumi- 

 gation is found to be more successful during the winter months. If properly- 

 carried out, one application of gas will be sufficient to clean the trees for one- 

 season. In some cases it will permanently clean them unless reinfested. 



Curl blight is a fungus disease that attacks the young shoots and leaves, 

 causing the latter to swell to a large size, become contorted, and eventually 

 dry up and fall. This disease may be controlled by the use of lime-sulphur 

 spray. The spray should be applied in the winter and continued up to the 

 early spring, using a weaker solution as the buds burst. Two applications 

 are generally sufficient (the first in midwinter and the second early in the- 

 spring), but where the disease has been very prevalent in the preceding 

 summer, it is wise to increase the number of applications to, say, three or 

 even four, before the buds burst. 



Coffee in New South Wales. 



The question " can coffee be profitably grown in this State '" reaches the 

 Department in some form or other with such frequency that recent corres- 

 pondence on the subject may be quoted with advantage. The prospect of 

 the local householder gathering his coffee beans as he now does his passion- 

 fruit is a pleasant one ; it obviously inspired the newspaper paragraph that 

 prompted the present inquiry, but it is unfortunately obscured by climatie 

 facts. 



" I have 70 acres of land 4 miles north of Gulgong, on which I have 

 an orchard, and have installed an irrigation plant," -wTote the correspondent. 

 " I would like you to kindl}' send me some coffee plants and instructions how 

 to grow them. This is a very hot, dry climate, and with irrigation coffee 

 trees should grow well." 



" Successful growing of coffee in this State, with the exception of a few 

 particularly well-sheltered positions on the Tvv^eed, is impossible." ran the 

 Department's reply. ' Frosts are fatal to the plant, and a fairly evert 

 temperature throughout the year, with a rainfall of 60 to 80 inches, is 

 desirable. Coffea arahiea and C. rohvsta are the two varieties most widely 

 known in the tropics, and a few fairly healthy plants of both are bearing 

 on the Tweed. Apart from the unsuitability of the climate, the high price 

 of labour for picking and preparing the berries would make the crop 

 impossible from a commercial point of view."
