SPRAYING

sprayed with a fine nozzle, a gallon will go much farther than the 

 same quantity of lime-sulphur. 



3. To use the soluble oil, stir thoroughly, and to 1 part oil add 

 15 parts water. When about to mix large quantities, it is well to 

 test the miscibility of the oil by pouring a few drops in a glass of 

 water and stirring it. If 

 a good milky emulsion 

 without free oil on the 

 surface is formed, the 

 solution is all right to 

 use. The spraying uten- 

 sils should be absolutely 

 clean. 



It should also be noted 

 that Bordeaux mixture, 

 Paris green, or lime- 

 sulphur are liable to spoil 

 the emulsion. 



Other materials. Pyrox, 

 Bordo Lead, Kil-o-scale, 

 Target Brand, Antiscale, 

 Scalecide, and a number 

 of other commercial brands 

 can be obtained from local 

 dealers, and in general do 

 very good work. They are 

 usually more expensive 

 than the regular materials, 

 and are not superior. 

 However, for those who 

 cannot prepare their own 



solutions or who have only a small amount of spraying to do, 

 stock-prepared solutions will answer the purpose. 



When to apply the spray. The first spraying is done when the 

 leaves have dropped in the fall, and before foliage appears in the 

 spring. The material used may be homemade lime-sulphur wash, 

 commercial lime-sulphur solution, miscible oils, whale-oil soap, or 

 nicotine solution, properly diluted to winter strength. This dormant

When the buds are developed like these it is time 



for the first spraying, to prevent scab. (Cornell
