No. 7. DEPARTMENT OF AGRICULTURE. 555 



MR. BROWN. — We will furnish scalecide at fifty cents a gallon 

 delivered anywhere east of the Mississippi River and north of the 

 Ohio and we will deliver it at sixty cents a gallon anywhere in the 

 United States. We guarantee that five gallons of scalecide in 

 ninety-five gallons of water will kill every scale you hit with it. 

 That will cost two and a half cents in this State and three cents 

 a gallon anywhere. 



There is one preparation on the market that is almost identical 

 with scalecide with the exception that it has sulphur in it and that 

 is called kiloscale. One gallon will cover twice the surface in 

 spraying with the same quantity of the lime-sulphur wash. The 

 one is a thin watery substance and the other is a whitewash. It 

 may be applied in one-half to one-third the time. In other words, 

 the labor of one hundred gallons of scalecide will cover twice as 

 many trees that you will with the lime-sulphur wash and you will 

 find it cheaper if you figure it out; take a cent and a quarter a gal- 

 lon for the lime-sulphur w^ash, because your labor is cheaper. I 

 have never heard of anybody who manufactured the lime-sulphur 

 wash and putting it out for less than two to three cents a gallon 

 and scalecide is worth two and a half to three cents a gallon. 



I have had some experience in spraying— having about 7,000 trees 

 — and have been spraying for 15 years. We do commercial work, 

 running a large power spraying outfit, putting out from 35,000 to 

 40,000 gallons of spray material annually. I travel a great many 

 states — selling spraying machinery and materials — which gives me 

 unusual opportunity for observation and brings me in touch with 

 many of the most extensive fruit growers of the country, by which 

 I am enabled to study their methods. I have used to a greater or 

 less extent, every leading remedy for San Jos6 scale upon the 

 American market, have been fighting this pest for twelve years — 

 and my experience leads me to believe that any one of these reme- 

 dies is effective in controlling the scale, if properly made and thor- 

 oughh" applied. Some are more dangerous than others. This ap^ 

 plies more particularly to petroleum oils, but we are now familiar 

 with their use, so that even crude petroleum can be applied without 

 any danger attending the application. I used the lime-sulphur near- 

 ly six years with good results; three years of this time I used the 

 self -boiled chiefly — and with perfect success, so when I hear ento- 

 mologists and fruit growers say that the self-boiled lime-sulphur 

 wash is not effective, I feel that they do not know what they are 

 talking about. In the use of any of these remedies, success depends 

 entirely upon the thoroughness wi\1i which the work is performed. 

 In fact it depends upon the man behind the nozzle. 



In Delaware we have practically abandoned the lime-sulphur wash, 

 the same is true of many of the larger fruit sections of the country, 

 not because the L. S. wash would not control scale, but because 

 of its many disagreeable features. Our people are now using scale 

 remedies with an oil base — and since the introduction of the "solu- 

 ble" or "miscible oils" and their value fully proven, we have aban- 

 doned the sulphur washes and have taken to the use of the miscible 

 oils. I do not say this because I am interested in the manufacture 

 and sale of these remedies, but because they promise to control 

 the scale more easily and more cheaply than any other remedy. I 

 believe I am well enough known upon this floor, not to be charged
