284 Peach-Groiving 



Raw linseed oil 5 gallons 



Gasoline 3 gallons 



Laundry soap 2 pounds 



Water 92 gallons 



According to the above authority — " The best way of 

 preparing this spray is by mixing 5 gallons of raw linseed 

 oil and 3 gallons of gasoline and then adding 2 pounds of 

 soap dissolved in 4 gallons of hot water. The whole is 

 churned for 5 minutes through a spray pump, then diluted 

 to double its volume and churned again for 1 minute, after 

 which it should be diluted to 100 gallons, when it is ready 

 to use." 



One thorough application made in the spring before the 

 buds burst has been found an effective means of controlling 

 the terrapin-scale. 



Arsenate of lead. 



This is the poison now used for biting and chewing in- 

 sects almost to the exclusion of all others. Its most im- 

 portant use in spraying peaches is for the control of the 

 curculio. For this insect it is nearly always used in com- 

 bination with a fungicide — quite habitually the self-boiled 

 lime-sulfur mixture — and at the rate of 2 pounds to 50 gal- 

 Ions of the mixture, or of water, if applied without a fun- 

 gicide. AVhen water is used as the conveyor, stone lime 

 freshly slaked should be added at the rate of 2 to 3 pounds 

 to every 2 pounds of the poison in order to prevent injury 

 to the foliage. 



The grower will not find it practicable to prepare this 

 poison himself, but he should purchase one of the well-tried 

 commercial brands, of which there are many in both powder 

 and paste form.
