An evaluation of CGA-43089 to protect grain sorghum from alachlor and metolachlor injury

Field studies were conducted to determine: (1) if seed protectant CGA-43089 [α-(cyanomethoximino)-benzacetonitrile] will protect grain sorghum (Sorghum bicolor L. Moench.) from the phytotoxicity caused by alachlor [2-chloro-2\u27,6\u27-diethyl-N-(methoxymethyl)acetanilide] and metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-l-methylethyl)acetamide] applied at different rates, and (2) the susceptibility of two grain sorghum cultivars to alachlor and metolachlor applied with and without the protectant. The effects of CGA-43089 at two rates (0, and 1.25 g/kg of seed) and alachlor or metolachlor at four rates (0, 2.2, 3.4, and 4.5 kg/ha) on two grain sorghum cultivars (Funk G-251 and Funk G-623GBR) were studied in experiments conducted at the Main Experiment Station, Knoxville, the Ames Plantation Experiment Station, Grand Junction, and the Martin Experiment Station, Martin, during 1978. Parameters measured at each location were percent vigor reduction, plant population, panicle production, mature plant height, average grain sorghum panicle weight, and grain yield. Early herbicide injury, as noted by vigor and stand reduction, was later expressed as reduced yields where nontreated seed were used. In general, the vigor reduction was less at 60 days after planting than at 30 days after planting. With CGA-43089 seed treatment, plant population, panicle production, and grain yield tended to be greater. The effect of seed treatment or herbicide application on plant height and average grain sorghum panicle weight was somewhat inconsistent. Plants of cultivar Funk G-251 tended to be shorter than those of cultivar Funk G-623GBR across practically all treatments. In general, cultivar Funk G-251, although nonbird resistant, appears to be better suited for production in Tennessee than cultivar Funk G-623GBR due to earlier maturity

Sound effects : The oral/aural dimensions of literature in English : Introduction

This collection derives from a conference held at the University of St. Andrews in 2006, one of an occasional series on the media in history as a context for literary interpretation.1 The aim of the conference was to extend our discussion of the literary media from printed text and script back to the most basic medium of all: speech. But we also wanted to explore points of contact between the established field of oral tradition and the emerging field of sound studies.Issue title: Sound Effects

The WFIRST Galaxy Survey Exposure Time Calculator

This document describes the exposure time calculator for the Wide-Field Infrared Survey Telescope (WFIRST) high-latitude survey. The calculator works in both imaging and spectroscopic modes. In addition to the standard ETC functions (e.g. background and S/N determination), the calculator integrates over the galaxy population and forecasts the density and redshift distribution of galaxy shapes usable for weak lensing (in imaging mode) and the detected emission lines (in spectroscopic mode). The source code is made available for public use.Comment: 44 pages. The current C source code and version history can be found at http://www.tapir.caltech.edu/~chirata/web/software/space-etc/ ; IPAC maintains a web interface at http://wfirst-web.ipac.caltech.edu/wfDepc/wfDepc.js
