EXPERIMENTS WITH INSECTICIDES UPON POTATOES. 183 



much as was desirable. The spraying with disparene was effec- 

 tive and cleared the field from bugs. 



Disparene was used by several farmers in the vicinity of Houl- 

 ton and, in some instances, the results were not satisfactory. 

 From our experience with arsenate of lead the trouble would 

 seem to be in the application rather than in the poison itself. 



SUMMARY. 



Arsenate of lead was used at the rate of one pound to the acre 

 and in the case of boxal much less than that. It is very readily 

 mixed with water and stays in suspension so that it is possible to 

 apply it much more evenly than Paris green. It adheres well to 

 the foliage and is the most effective of any of the insecticides 

 tried. 



BUG DEATH. 



The Danforth Chemical Company of Leominster, Mass., have • 

 put upon the market a preparation for which they make great 

 claims and for whose merits some users fail to find language too 

 strong in which to extol the goods. The advertising circular of 

 1900 says : 



"The farmers who used Bug Death freely the past season on 

 potatoes had a large crop of good smooth potatoes that actually 

 brought a higher price in the market than those of their brother 

 farmers who did not use Bug Death, but who did use some of 

 the many insecticides that contain arsenic. 



"Why should you feed your crops on a deadly poison? Is it 

 not better to feed them with something that is a plant food, as 

 well as an insecticide, thus freeing the plant of the insects and 

 promoting growth, which increases yield and improves quality, 

 especially when blight is prevalent? If used according to direc- 

 tions the extra yield will more than pay the entire expense. 



"If you have made a test of it we rest assured that you will 

 be a permanent customer. If to you it is new or unheard of we 

 ask that you read these testimonials which, coming as they do 

 from prominent dealers (all of whom are well and favorably 

 known to the people of their respective states), will, we are sure, 

 induce you to at least give Bug Death a trial, and then we are 

 confident that the practical results derived from its use will con- 

 vince vou of its merits."
