_Bordeaux mixture_ is the standard fungicide. The formula which calls for four ounces lump lime, four ounces copper sulphate (bluestone) and three gallons of water is the one most commonly used. It is made by dissolving four ounces of bluestone in an earthenware or wooden vessel in one and one-half gallons of water. The lime is slaked in another vessel by adding water gradually until it forms a mixture of a milky consistency. Add more water to make one and one-half gallons and strain through cheese-cloth. After it has been strained it should be thoroughly mixed with the copper-sulphate solution and used immediately. Bordeaux mixture made in this way will not keep, but should be applied the same day. Stock solutions of copper sulphate and lime will keep indefinitely if they are not mixed together. _Liver of sulphur (potassium sulphide)_ is valuable for spraying plants affected with mildew. Use one ounce dissolved in three gallons of water. This solution discolors paint. The following are some of the common diseases affecting vegetable crops: Beans are attacked by _anthracnose_. It causes dark-colored, sunken spots to appear on the leaves, stems, and pods. It frequently penetrates to the seeds. Infected seeds should never be planted. It pays to look over all beans that are to be used for seed and destroy all that are discolored. Never work among the bean-plants when they are wet, as the disease, if it is present, is easily spread by this means. _Beets_ are subject to a _leaf-spot_. This causes small, round, dead spots to appear on the leaves. Bordeaux mixture applied as soon as the spots appear and at intervals of one or two weeks will check this disease. Cabbage.—_Clubroot_ is a disease which causes the roots of cabbage, cauliflower, kohlrabi, and allied plants to become swollen and deformed, and prevents them from functioning properly. If it is not noticed at transplanting-time the first indication of its presence is the sudden wilting of the plants. All affected plants should be destroyed. The seedbed and that part of the garden where the cabbages are to be planted should be limed two or three months before planting. Use between fifty and sixty pounds of air-slaked lime on a plot twenty by twenty feet, and thoroughly mix it with the soil. Corn.—_Corn smut_ usually appears as swellings, covered with a silvery membrane, on the tassels or ears. These break open later and disclose the masses of dark-colored spores. The swellings should be cut off and destroyed before they burst. Cucumber.—_Anthracnose, angular leafspot_, and _downy mildew_ are diseases attacking the leaves of cucumbers which can be controlled to some extent by frequent spraying with Bordeaux mixture. This should be applied as soon as the diseases are noticed and repeated at intervals of one or two weeks.
