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.
