64S NEW JERSEY STATE AGRICULTURAL. 



by the Soiitlierii Oil and Chemical Company. INIobile, Alabama. 

 Added to water it forms milky emulsion, fragrant in odor, and 

 leaves when drying, a thin, sticky residue. 



There >vas only a small amount of material supplied, and it 

 was used at the rate of one part of Pyrol to 40 parts of water, 

 although I part to 50 was\ recommended. Application was 

 made June 30th, through a ''Mistry" nozzle, and the trees were 

 thoroughly covered. Unfortunately, within two hours there- 

 after, it began to rain and w^as showery throughout the night. 

 It is more than probable, therefore, that the material was washed 

 away in great part, and did not produce aS: good an effect as it 

 might ha\'e done otherwise. Lack of material prc'ented my 

 duplicating the experiments. 



Six trees were treated : 



1. Mariana Plum. With many recently set scales and active 

 larv?e. The application was imperfect in that the tree was 

 sprayed from one side only ; but from that one side the applica- 

 tion was thorough. Julv 8th, the foliage appeared to be some- 

 what scalded in the center; but no apparent effect upon the scale 

 could be discerned. 



2. Apple. Gravenstein. i ; Yellow Transparent, i ; Baldwin, 

 I. All t)f these were pretty well peppered by developing young 

 and recent sets — ideal conditions for a material of tliis kind — 

 and all were thoroughly treated. A week later conditions had 

 not impro\ed, but were on the contrary, much worse; the ma- 

 terial had been absolutely ineft'ective.. 



3. Pear. Vermont Beauty, 2. Were in the same condition 

 as the apples, were treated as thoroughly and the result was 

 identical : the scale was in no way reduced. No sort of injury 

 was caused to the foliage of either apple or pear. 



HORTICULTURAL COMPOUND. 



This is a soap mixture, originally manufactured at Port Mon- 

 mouth, New^ Jersey, and intended for general insecticide work; 

 more especially as against plant lice and the like. It has the 

 appearance of a resin soap, containing alsd tobacco' as an ac- 

 cessory, and in texture is like a hard butter. It dissolves quite 

 readily in warm water. All applications were made through 

 a Vermorel nozzle, at the rate of 2 ounces in i gallon O'f water, 

 or double the strength recommended on the circular received with 

 the material. 



Julv 5th, sprayed my entire row of grapes, about y^ feet in 

 length, to- test against the leaf hoppers, which were verv abundant
