. Better fruit. Fruit-culture. STEAM PLANT FOR COOKING Photograph by James H. Bcattic LIME-SULPHUR-SALT WASH FRUIT TREE BARK BEETLE (SCOLYTUS RUGULOSUS) a. Adult beetle; b, Same in profile; c, Pupa: d. Larva. (From Chittenden.) Attacks plum in preference, and the apple, peach and cherry are about equally attractive. Pear, quince, apricot, nectarine, mountain ash and Juneberry are also infested. mula, 5 per cent commercial sulphuric acid and 10 per cent ferrous sulphate, with water, applied thoroughly. In this experiment twigs and buds were killed, but not to the extent as with 10 per cent sulphuric acid. A few of the mildewed twigs remained alive, and two of these put out mildew infested buds. The tree did not make a specially healthy growth and was badly mildewed by midsummer. There has been a large quantity of spraying with lime-sulphur solution dur- ing the last two years. The strength used has been that recommended for the San Jose scale, that is the 1-1-3 and 1-1-4 formulas or their equivalent in the commercial solution. The applications have been made during the entire dor- mant period and under all weather con- ditions. It would seem, then, that this large amount of commercial spraying should afford the best possible data upon the efficiency of the lime-sulphur solu- tion against the winter form of the mil- dew. Our observations have shown that the mildew develops from the infected shoots, apparently unchecked even by the most thorough lime-sulphur applications. Lime-sulphur three times the usual strength (commercial solution 1 to 2): applied to three-year-old Bellflower; date, February 21, 1908; day cloudy, tempera- ture moderate. The application was very thorough in the endeavor to cover all mildewed twigs. The deposit made by.
