FOR fumigsting, the specialists rec
ommend hydrocyanic-acid gas carbon
disulphlde, or sulphur dioxide, These
are effective against all classes Of In
sects when Il is desirable to use them.
Arpsnats OF lead Most Widely Used.
Arsenate OF lead is the best known
and most extensively used stomach
poison for insects II has n wider
range Of usefulness than any other
internal poison now available. II Is
safe for use on the foliage OF most
plants, has good adhesive qualities,
and owtag TO its fineness, remains In
suspension well In water. Moreover,
Il can be safely combined with GER
tain contact sprays, as nicotine, ker-
osene emulsion. soaps, etc. and with
q number Of fungicides such as lime
sulphur mixture. and bordeaux mix
ture. II should not be combined with
sodium or potassium sulphides,
