Experiment Station.
In the third annual report of the
New York Agricultural Experiment
Station is to be found statement OF
results gained o. the station grounds
with various insecticides. The expert.
ence there led TO the opinion that d
special mode of treatment must be
adopted for almost every destructi,,
insect.
The turnip flea-bcctle was expert
mented upon with several insect
cides A strong decoction of Tobacco,
co proved very efficient when frequent
~ applied, but its efficacy appeared
be lost after about ten days KcrOscn
emulsion, diluted with eight parts q,
soft water, was also efficient, but TN
effects were little if any more lastin
than those of the tobacco water an
when frequently applied retarded th
growth of the plants. Tobacco leave
cut fine, when placed about the plan
of the radiSh had marked effect j
Keeping of the beetle. This appl
cation as well as that of d,
cOctiOn of tobacco seemed {

Air-slacked lime, busted over the plant
when wet, proved unqucstionably beneG
cial and in dry weather its effects wer,
quite lasting.
1t was noted that the plants of cab
bagc, radishes, etc. grown i'm the col,
frame are scarcely injured by the fea
beetle. None of the applications use,
for the ilca-beetle had any pcrceptibl
effect in preventing injuries from tn
radish-Hy, but satisfactory results wer,
gained by the use of coal ashes.
The only application that appeared
TO prevent the injuries of the stripe,
cucumber beetle was Paris green nike,
