PLASMA OUTFLOW AND SUPERROTATION IN THE JOVIAN MAGNETOSPHERE DEDUCED FROM VOYAGER OBSERVATIONS (JUPITER, T. W. HILL, PEDERSEN CONDUCTIVITY, V. M. VASYLIUNAS, IONOSPHERE)

Autor: HAIRSTON, MARC ROTAN

Magnetometer and plasma science data from the Voyager 1 and Voyager 2 encounters of Jupiter are combined with earlier theoretical analysis by T. W. Hill and V. M. Vasyliunas to determine the total mass outflow rate and radial bulk velocity of the mag

Meta-Analysis of Soybean Yield Response to Foliar Fungicides Evaluated from 2005 to 2018 in the United States and Canada

Publikováno v: Plant disease. 105(5)

Random-effect meta-analyses were performed on data from 240 field trials conducted between 2005 and 2018 across nine U.S. states and Ontario, Canada, to quantify the yield response of soybean after application of foliar fungicides at beginning pod (R

Evaluation of an Aeroponics System to Screen Maize Genotypes for Resistance to Fusarium graminearum Seedling Blight

Autor: H. Walker Kirby, Lindsey J. du Toit, W. L. Pedersen

Publikováno v: Plant disease. 81(2)

A noncirculating aeroponics system was evaluated as a method for rapid screening of maize genotypes for resistance to Fusarium graminearum seedling blight/root rot. The system allows for nondestructive, repetitive sampling of seedlings for assessing

Autor: R. A. Leitz, D. D. Hoffman, Daren S. Mueller, W. L. Pedersen, C. D. Nickell, Glen L. Hartman

Publikováno v: Plant disease. 82(7)

Sclerotinia stem rot (SSR) is one of the most important diseases of soybean in the United States. Five maturity group III cultivars, Asgrow A3304 STS (A3304), Pioneer Brand 9342 (P9342), Pioneer Brand 9381 (P9381), Probst, and Yale, grown in fields i

Response of Soybean Accessions from Provinces in Southern China to Phytophthora sojae

Autor: C. D. Nickell, D. E. Kyle, Randall L. Nelson, W. L. Pedersen

Publikováno v: Plant disease. 82(5)

Phytophthora rot, caused by Phytophthora sojae, is a damaging disease of soybean (Glycine max (L.) Merr.) throughout the soybean-producing regions of the world. The discovery of new sources of resistance in soybean is vital in maintaining control of

Races of Phytophthora sojae on Soybean in Illinois

Autor: C. D. Nickell, Glen L. Hartman, W. L. Pedersen, R. A. Leitz

Publikováno v: Plant disease. 84(4)

Phytophthora root rot of soybean (Glycine max (L.) Merr.), caused by Phytophthora sojae M. J. Kauffmann & J. W. Gerdemann, has been isolated throughout the soybean-producing regions of the United States. There are more than 39 identified races of P.

First Report of Phomopsis longicolla from Velvetleaf Causing Stem Lesions on Inoculated Soybean and Velvetleaf Plants

Autor: Glen L. Hartman, Carl A. Bradley, Shuxian Li, W. L. Pedersen

Publikováno v: Plant disease. 85(9)

Reddish brown lesions were observed on the lower stem and upper root area of velvetleaf (Abutilon theophrasti Medik.) plants growing in an Illinois soybean field in June 2000. The lesions were similar in appearance to those caused by Rhizoctonia root

Use of Aeroponic Chambers and Grafting to Study Partial Resistance to Fusarium solani f. sp. glycines in Soybean

Autor: Shuxian Li, Glen L. Hartman, Daren S. Mueller, W. L. Pedersen

Publikováno v: Plant disease. 86(11)

Several plant introductions (PIs) and cultivars have been classified as partially resistant (PR) to sudden death syndrome. However, little is known about the nature of resistance to this disease. Seedlings of two PR PIs and two susceptible cultivars
