from these pests. The fruits have not set like this for at least eight 

 years back. I cannot speak too highly of your recommendation."

7. " I think your winter wash of caustic soda-emulsion spray 

 is the most effective of all those I have tried, it cleared the trees of 

 the great majority of their pests." (Hereford.) 



The Evesham correspondent of the " Fruit-Grower " writes to that 

 paper (April 4th, 1907, pp. 258, 259) as follows: 



" I have been much interested in the spraying of five acres of fruit 

 trees here, the more so as strict account has been kept of cost, method 

 and time. The trees are Apples and Plums, in alternate rows, i6ft. 

 high by I2ft. through. These were sprayed for Psylla with winter 

 wash (Mr. Collinge's formula). The quantity of ingredients used and 

 cost were : 



Royal Daylight Oil, 95 gallons ... ... 280 



Caustic Soda, 98 per cent. ... ... 300 



Chiswick Imperial Soft Soap, 2 firkins ... I o o 



Labour ... ... ... ... 600 



Horse Hire and Incidentals ... ... 150

Or, say, 553. per acre. The machine employed was the Canadian spray 

 motor. Two sprays were worked at once, and the work was done very 

 thoroughly. The nozzles were the Canadian spray nozzles (medium) 

 one single and one with three nozzles. The latter was by far the most 

 satisfactory and expeditious. Although it is too early yet to judge 

 the efficacy of the work, still a great number of- Psylla eggs show 

 cracked under the microscope, and there is no doubt in the mind of 

 the proprietor that incalculable good has been accomplished. But 

 the main point of interest to growers is that this shows that spraying 

 can be done effectively and cheaply, 553. per acre being a moderate 

 cost. Of course, this spraying was well planned and managed, and 

 management in this matter is everything. 



' One grower finds that his Gooseberry-bushes, grown under trees 

 recently sprayed with the above wash, are entirely free from Red 

 Spider, which has hitherto plagued them, while other bushes which 

 have had no contact with the spray are badly infested. Perhaps this 

 experience can be duplicated. Growers, please note."
