ORTHO ARSENATE OF LEAD
During the spring of 1903 the University of California commenced an investigation of the Codling Moth problem in the great apple growing districts known
as the Pajaro Valley. Here the damage to the apple crop due to worms was yearly becoming greater and the common method of control (spraying with Paris Green)
Ccl USC Of WaS' aS n oter sectons' verv unsatisfactory. This spraying with Paris Green, while it reduced the number of worms, caused far greater damage
D . than any generally experienced because of the very foggy summer climate of the Valley. These wet fogs caused the arsenic in the poison to

dissolve and so penetrate and burn the leaves. Such injury was often many times greater than that caused by the Codling Moth.
At this time Arsenate of Lead was just being introduced and several brands were experimented with. The results were much better than those ob
tained with Paris Green, but injury still followed the application in some cases. Further investigation developed the fact that Arsenate of Lead, as
rHff iflllf V generally prepared and sold, was really a mixture of two chemical compounds, one of which (ORTHO-Arsenate) was safe under all climatic
A " conditions, but the other (Pyro-Arsenate) would injure foliage when enough moisture was present.
I" Oil nil The discovery of the compound of Arsenic and Lead which could be depended upon to kill the worms and yet positively would not injure
the foliage was only half the battle. This Ortho-Arsenate of Lead was not manufactured in the pure state by any existing companies so could not be obtained.
It was therefore necessary to establish a factory for the manufacture of Artho-Arsenate of Lead that would come up to these requirements.
TrOllble US was e California-Spray-Chemical Co. was organized in 1907. This company makes a specialty of Ortho-Arsenate of Lead
. and so successful has it been in meeting the requirements that no other brand is used in the Pajaro Valley which produces 4000 cars of apples
vVrneUieCl annually. During the past two years it has proved itself to be the safest and most satisfactory poison in all the great spraying
districts of the West.
Here's Why You Should Use Ortho-Arsenate
1. It is sure to Kill if you have it in the right place at the right time because it is strength and purity.
2. It will not produce poisoning of the soil.
3. It cannot barn. Arsenate itself will burn, but when properly combined with lead it cannot.
4. A United States Patent protects the manufacturers in their process of perfectly combining these substances.
5. It is put up in a steel container; hence full net weight always no leakage.
6. If you carry over part of a package the cover fits so snugly as to make the can water and air tight. Wood packages leak, and tin pack
ages rust; we avoid both.
7. It is put up in convenient sizes for handling 5, 10, 20 and 50 pound cans.
8. Haterial has been analized and passed upon by the experiment stations of California, Oregon, Washington and Utah.
9. It costs no more than other kinds.
10. Last, but not least
It is a netural arsenate and will not precipitate the sulphur in your first
spraying with lime and sulphur
