Resistant vines better than the best insecticides as a means against Phylloxera 
vastatrix ; principal insecticides in use, especially arsenical substances, pe¬ 
troleum and pyrethrum; method of action and mode of application of 
these insecticides, especially application by the cyclone nozzle, and the 
subterranean application of kerosene emulsion as a means against Phyl¬ 
loxera vastatrix ; tobacco vapor, under favorable conditions, would probably 
kill this insect.
