THi; TWIN FALLS, IDAHO, ONE HUNDRED EIGHTY FEET HKUI IRRIGATION SYSTEM, TWIN FALLS, IDAHO Continued from page 45 October, using either bordeaux mixture 4-4-50, or lime-sulphur, summer strength. Treatment for bearing orchard: First, spray with lime-sulphur, diluted to sum- mer strength, just as the blossom buds begin to separate in the cluster and show color, or slightly before. This is the first spray for apple scab. In case bud moth or other leaf-eating insects are present; add arsenate of lead in the proportion of two pounds to each fifty gallons of spray. If aphids are troublesome, add black leaf or black leaf 40 as above. Second, spray with lime-sulphur, summer strength, to which two pounds of arsenate of lead has been added to each fifty gallons, just after the petals have fallen. This is the second scab and the first codling moth spray. Third, in orchards that are badly infested with apple scab, spray ten days or two weeks after the second spraying with lime-sulphur, summer strength, or with self-boiled lime-sulphur (8-8-50). This is distinctly a scab spray, and in regions where scab is not prevalent may be omitted. Where codling moth or leaf- eating insects are present, two pounds of arsenate of lead should be added to each fifty gallons of spray. In those sections of the state where scab is not present and it is necessary to spray for leaf- eating insects, arsenate of lead may be diluted with water in the proportion of two pounds to fifty gallons. Fourth, the second spray for codling moth should be applied at the time the moths are depos- iting eggs for the first generation, or just as the very earliest worms are beginning to enter the fruit. In the greater portion of the Willamette Valley this will be usually between June 25 and July 1, although the dates may vary somewhat with the season. This date is also approximately correct for most portions of the Hood River Valley, but in South- ern Oregon and the warmer parts of the Gr
