Neutral Arsenate of Lead 



A strictly neutral Arsenate of Lead is the only kind that should 

 be used by growers on the Pacific Coast and irrigated sections. 

 Any other kind is exceedingly dangerous. 



Sherwin-lVilliams New Process Arsenate of Lead is the highest 

 possible type of this form of material. 



A Neutral Arsenate of Lead 

 is the only form that can be 

 safely combined with Lime- 

 Sulfur Solution for summer 

 spraying, and Sherwin-Will- 

 iams New Process Arsenate of 

 Lead is especially made for 

 this purpose. An acid Arsenate 

 of Lead when combined with 

 Lime-Sulfur will cause severe 

 burning. 



Because of our special method 

 of manufacture, this product 

 has greater adhesiveness than 

 any other combination of lead 

 and arsenic. By reason of its 

 complete and thorough combi- 

 nation it is affected very little 

 by alkalies and will not poison 

 the soil or trees. 



Read the following extract regarding the value of 

 a Neutral Arsenate of Lead, from a paper by Pro- 

 fessor O. S. A^'atkins of the University of Illinois, 

 read before the Fifty-fifth Annual Convention of the

 i\Iy extended absence from home has 

 prevented my answering your inquiry 

 sooner. I am pleased to inform you that 

 my last year's experience with your 

 Arsenate of Lead spray has been very 

 satisfactory. While the test made during 

 the seasons of 1909 and 1910 was all that 

 one could expect in controlling the cod- 

 ling moth, yet my last year's test was 

 still better. My total loss (by actual 

 count) of injured fruit was a little less 

 than one-fifth of one per cent. My crop 

 was about 8,000 boxes or bushels. I used 

 your Arsenate of Lead four times: 



First spray, just as the calyx was begin- 

 ning to close. 



Second spray, one month later. 

 Third spray, about three weeks later. 

 Fourth spray, three weeks later. 

 While my crop was practically free 

 from injury by the Tnoth, some of my 

 neighbors who used other sprays, early 

 applied, had a very heavy loss. 



Yours sincerely, 



A. L Mason.

"Chemically speaking, there 

 are a number of Lead Arse- 

 nates; however, the two most 

 common ones are the neutral 

 and acid. The commercial 

 brands are generally a mixture 

 of the two, sometimes the acid 

 predominating and vice versa. 

 Only one, Sherwin-Williams, 

 proved to be entirely neutral." 

 In this test Sherwin-Williams 

 Lead showed only 6.3% russet, 

 while the next lowest showed 

 22%. 



Because of its thorough com- 

 bination with lead it never 

 burns the foliage or russets the 

 fruit. 



Sherwin-Williams New Process Arsenate of Lead 

 is endorsed as a high grade Neutral Arsenate of 

 Lead by all leading disinterested authorities. Guar- 

 anteed under Insecticide Act of 1910.
