This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1913 Excerpt: ... Spraying with Bordeaux mixture (XVIII), as for downy mildew, will hold it in check for a time at least. Repeat every seven to nine days, and be thorough. Lettuce Lettuce-rot.--Caused by a rot fungus, and is more frequent indoors than out. The plants rot off at the surface, and the central portion of heading varieties becomes attacked. Sterilize the soil with steam. Maintain a temperature of less than 500 Fahr. at night; too high a temperature helps to induce rot. Ventilate the house thoroughly at all times. Burn all infested portions of the plants. Onions Black Onion-fly.--A white maggot, a little larger than the onion maggot, that feeds on stored as well as growing onions. Fumigate stored onions with bisulphide of carbon for forty-eight hours, using one pound of liquid to one hundred cubic feet of space to be treated. Onion-maggot.--The maggot (grub) of a small fly, resembling the house-fly. The egg is laid on the young plants early in the season, and the grub eats into the bulb. The treatment for cabbage maggots helps. Kerosene-soaked sand placed about the plant also helps. Fertilize freely, to stimulate a strong growth. Thrips.--Small (one-twentieth of an inch long), active, yellowish-winged insects, that jump like fleas, and feed on the skin of the leaves. Clean away all weeds from about the garden, before planting. Spray frequently, when insects are found to be present, with kerosene emulsion (V) or tobacco water (IXb). Smut.--A very bad fungus that attacks the plants when they are very young. It appears in the form of a black, dusty powder on various parts of the plant. Onions started in sterile soil, and transplanted outdoors later, will not be attacked. Where seeds must be planted outdoors in infected soil, sow flowers of sulphur in the rows, or pu...
