danger of staining the fruit with spray applications made much later 
than the middle of July is an additional reason for making the second 
application not later than that date. 
Nearly every season since spraying grapevines with a poison lias 
become a practice there has been more or less rumor concerning ill- 
ness of persons by poisoning resulting from the eating of sprayed 
grapes. We have given considerable attention to looking up reports 
of this nature but have never been aide to secure direct evidence of 
poisoning of persons in this manner. From our observations and

experiments with poison sprays against the grape root-worm beetle 
and all other insect pests known to us at present in vineyards in the 
Lake Erie Valley, all applications should be made 4 in normal seasons 
not later than the middle of July, and in exceptionally late seasons 
like that of 1907 not later than July 25. If vineyardists will en- 
deavor to make their last poison application before that date they 
need have no fear of either staining their fruit or creating cause 
for rumor of poisoning by persons consuming the same and also 
may feel assured that they have made the applications at a period 
when they will prove most efYective in the control of this pest.
