Calibrating Your Orchard Sprayer
The costs of fungicides, miticides, insecticides, foliar nutrients, wetting agents and plant growth regulators continue to increase. For a full spray program on apples, for example, the cost of spray materials alone could cost 1700 per acre per year. A poorly calibrated sprayer applying an average of 10% more material than intended, directly increases production costs by 170 per acre. Nozzles on sprayers wear out over time, and flow rates increase as nozzles wear, with worn nozzles eventually increasing flow rates by 10% or more. Financially sound management requires carefully calibrating orchard sprayers to optimize the benefits from applying spray materials

The Consolidation of the White Southern Congressional Vote
This article explores the initial desertion and continued realignment of about one-sixth of the white voters in the South who, until 1994, stood by Democratic congressional candidates even as they voted for Republican presidential nominees. Prior to 1994, a sizable share of the white electorate distinguished between Democratic congressional and presidential candidates; since 1994 that distinction has been swept away. In 1992, a majority of white southern voters was casting their ballot for the Democratic House nominee; by 1994, the situation was reversed and 64 percent cast their ballot for the Republican. Virtually all categories of voters increased their support of Republican congressional candidates in 1994 and the following elections further cement GOP congressional support in the South. Subsequent elections are largely exercises in partisanship, as the congressional votes mirror party preferences. Republicans pull nearly all GOP identifiers, most independents, and a sizeable minority of Democratic identifiers. Democrats running for Congress no longer convince voters that they are different from their party’s presidential standard bearers—a group that has consistently been judged unacceptable to overwhelming proportions of the southern white electorate.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline
