Responses ofHeterodera glycinesandMeloidogyne incognitaInfective Juveniles to Root Tissues, Root Exudates, and Root Extracts from Three Plant Species
Plant Disease - Tập 102 Số 9 - Trang 1733-1740 - 2018
Congli Wang, Edward P. Masler, Stephen T. Rogers
The infective juvenile (J2) stage of endoparasitic plant nematodes uses plant chemical signals, released from roots, to localize and infect hosts. We examined the behaviors of soybean cyst nematode (Heterodera glycines) and root-knot nematode (Meloidogyne incognita) J2 in the presence of root signals from marigold (Tagetes patula), soybean (Glycine max), and pepper (Capsicum annuum).

First Report of Beet mosaic virus Infecting Chickpea (Cicer arietinum) in Tunisia
Plant Disease - Tập 94 Số 8 - Trang 1068-1068 - 2010
Safaa G. Kumari, Asma Najar, N. Attar, Mai Hlaing Loh, Heinrich-Josef Vetten
Chickpea plants with severe yellowing and tip wilting were observed in the Cap-Bon Region of Tunisia in 2006. The viral-like symptoms resulted in yield loss of approximately 25% in some fields. A total of 110 symptomatic chickpea plants was collected from nine chickpea fields and tested at the Virology Laboratory of ICARDA, Syria for eight legume viruses using tissue-blot immunoassay (TBI...... hiện toàn bộ
Fumigation of Fruit with Short-Chain Organic Acids to Reduce the Potential of Postharvest Decay
Plant Disease - Tập 82 Số 6 - Trang 689-693 - 1998
P. L. Sholberg
Vapors of acetic (1.9 or 2.5 μl/liter), formic (1.2 μl/liter), and propionic (2.5 μl/liter) acids were tested for postharvest decay control on 8 cherry, 14 pome, and 3 citrus fruit cultivars. Surfacesterilized fruit were inoculated with known fungal pathogens by drying 20-μl drops of spore suspension on marked locations on each fruit, placing at 10°C to equilibrate for approximately 24 h,...... hiện toàn bộ

Phylogenetic and Pathogenic Analyses Show That the Causal Agent of Apple Ring Rot in China Is Botryosphaeria dothidea
Plant Disease - Tập 96 Số 4 - Trang 486-496 - 2012
Wei Tang, Zaisong Ding, Zhigang Zhou, Y. Z. Wang, Liyun Guo
Apple ring rot and Botryosphaeria canker are severe diseases affecting apple production in China, but there is confusion regarding which pathogens cause these diseases and their similarity to other diseases, such as white rot of apple, and ring rot and Botryosphaeria canker of pear. In this study, the pathogen of apple ring rot in China was compared with the pathogen of apple ring rot in ...... hiện toàn bộ

Triticum mosaic virus: A New Virus Isolated from Wheat in Kansas
Plant Disease - Tập 92 Số 5 - Trang 808-817 - 2008
Dallas L. Seifers, T. J. Martin, T. L. Harvey, John P. Fellers, James P. Stack, Marietta Ryba-White, Stephen Haber, Oleg V. Krokhin, Victor Spicer, Nicole E.J. Lovat, Andrej Yamchuk, Kenneth G. Standing
In 2006, a mechanically-transmissible and previously uncharacterized virus was isolated in Kansas from wheat plants with mosaic symptoms. The physiochemical properties of the virus were examined by purification on cesium chloride density gradients, electron microscopy, sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), sequencing of the nucleotides and amino acids of th...... hiện toàn bộ
Quantification of Yield Loss Caused by Triticum mosaic virus and Wheat streak mosaic virus in Winter Wheat Under Field Conditions
Plant Disease - Tập 98 Số 1 - Trang 127-133 - 2014
Emmanuel Byamukama, Stephen N. Wegulo, T. Satyanarayana, Gary L. Hein, Shawn M. Kaeppler, P. Stephen Baenziger, Ron French
Triticum mosaic virus (TriMV) and Wheat streak mosaic virus (WSMV) infect winter wheat (Triticum aestivum) in the Great Plains region of the United States. The two viruses are transmitted by wheat curl mites (Aceria tosichella), which also transmit High Plains virus. In a field study conducted in 2011 and 2012, winter wheat cultivars Millennium (WSMV-susceptible) and Mace (WSMV-resistant)...... hiện toàn bộ
