MR. 8T0CKWELL: And could you use the commercial? 



PROF FARLEY: Some growers have used the dilute 

 strength of the commercial lime-sulfur mixtures, but would 

 never recommend it on peach trees, because of the liability 

 of serious burning of the foliage. We have had that experi- 

 ence so many times that we have given up the use of the 

 commercial concentrated or home-made concentrated lime- 

 sulfur on peach trees after the leaves have appeared. We 

 make a second application of self-boiled lime-sulfur and ar- 

 senate of lead .just as the little husks on the small fruit are 

 splitting and falling oft'. You will find self-l)oiled lime-sul- 

 fur a very simple mixture to prepare after you have tried 

 (>nce or twice. There is nothing difficult about it at all. 



THE PRESIDENT: It might be interesting to have you 

 tell us just how that is done, the process of making your 

 self-boiled lime-sulfur. 



PROF. FARLEY : We use as a formula, 8 pounds of 

 stone lime and 8 pounds of sulfur with water to 

 make 50 gallons. If we have any amount of spraying to do, 

 and wish to use more than 50 gallons of spray mixture we 

 increase proportionately the amounts of lime and sulfur. If 

 we have a 100-gallon or a 150-gallon tank, we make up 

 tnough mixture at one time to fill the tank. For instance, if 

 we Avant 100 gallons of the self-boiled lime-sulfur, we use 16 

 pounds of lime and 16 ])ounds of sulfur, together with suf^- 

 cient water to make 100 gallons of mixture. We get better 

 results when the larger quantities of lime and sulfur are 

 used, l)(>cause the mixture is nuide, not ])y boiling with heat 

 or l)y steam, but simi)ly from the heat of the slaking lime 

 You nuist have good lime that will slake vigorously and 

 quickly with intense heat. The quality of the lime is very es- 

 sential in making the self-boiled lime-sulfur. We first mix the 

 sulfur in a tub with water to form a thick paste. The lime 

 is then j^laced in the bottom of a barrel and .iust enough 

 water poured over the lime to start it slaking. When the 

 slaking becomes vigorous we add our sulfur paste and 

 thoroughly mix the sulfur paste with the slaking lime, ^fore
