POISONOUS REMEDIES
12.--_Paris green:_--This is the standard remedy for eating-bugs
and worms. With a modern dusting machine it can be put on dry, early in
the morning when the dew is still on. Sometimes it is mixed with
plaster. For tender plants easily burned by
the pure powder, and where
dusting is not convenient, it is mixed with water at the rate of 1 lb.
to 50 to 100 gals. and used as a spray. In mixing, make a paste of
equal quantities of the powder and quicklime, and then mix thoroughly
in the water. It must be kept stirred up when using.
13.--_Arsenate of lead:_--This has two advantages over Paris
green: It will not burn the foliage and it will stay on several times
as long. Use from 4 to 10 lbs. in 100 gals. of water; mix well and
strain before putting in sprayer. See also Chapter XVII.
14.--_Hellebore:_--A dry, white powder, used in place of Nos. 12
or 13 on vegetables or fruit that is soon to be eaten. For dusting, use
1 lb. hellebore to 5 of plaster or flour. For watering or spraying, at
rate of 1 lb. to 12 gals. of water.
