wafted about by the wind, lodge on tender

plant. By keeping a thin film of Grape

Japtox 
Kills and repels Japanese 
Beetles 
This material is a real 
protection to foliage against 
the ravenous feeding of 
these pests. It is a fine, 
white powder with a slightly 
gray cast, which, when 
sprayed on foliage, estab¬ 
lishes a very pronounced 
silvery coating. This coat¬ 
ing or film spreads evenly 
over all of the surface to which it has been 
applied and sticks longer than any other 
spraying material known to chemical science. 
Japtox has as its base an arsenical poison so 
as to insure killing the small percentage of 
beetles which may actually feed on the 
sprayed foliage. Spray early when the first 
beetles are seen. A one-pound canister will 
make 10 gallons of spray.
