(2009-04-15)
Rice blast, caused by Magnaporthe grisea, is a devastating problem in all rice producing areas of the world and is extremely difficult to prevent and/or to control. Therefore, it is critical to develop new methods to ...
Identification of resistant or tolerant commercial cotton cultivars to the Fusarium wilt root-knot nematode disease complex and the identification of Fusarium oxysporum f. sp. vasinfectum races in Alabama
(2015-05-05)
Fusarium oxysporum Schltd.:Fr. f. sp. vasinfectum (Atk.) W.C. Snyd. and H. N. Hans (FOV) is the causal agent of Fusarium wilt in cotton. This causal agent is a soil-dwelling fungus that can remain dormant for many years ...
Identification, Distribution and Vector Biology of Brome Mosaic Virus of Wheat in Alabama
(2005-12-15)
Wheat leaves were collected from different counties in Alabama. The collected wheat leaves were tested for the presence of Brome mosaic virus (BMV) using direct double antibody sandwich ELISA. BMV was identified from ...
Identifying Integrated Pest Management Strategies for corn earworm, Helicoverpa zea, in Hemp
(2023-07-27)
Corn earworm, Helicoverpa zea (Lepidotera: Noctuidae), is a polyphagous insect species that feeds on the foliar, fruiting, and flowering structures of their host plants. In hemp (Cannabis sativa L.) corn earworm feeds on ...
Impact of cogongrass (Imperata cylindrica) presence and management strategies on arthropod natural enemy populations in longleaf pine stands
(2012-04-09)
Cogongrass (Imperata cylindrica Beav.) is an aggressive, invasive weed that is threatening the integrity of longleaf pine (Pinus palustris Mill.) ecosystems in southeast Alabama. Various management strategies are implemented ...
Impacts of Native and Non-native plants on Urban Insect Communities: Are Native Plants Better than Non-natives?
(2015-12-11)
With continued suburban expansion in the southeastern United States, it is increasingly important to understand urbanization and its impacts on sustainability and natural ecosystems. Expansion of suburbia is often coupled ...
Induction of Growth Promotion and Stress Tolerance in Arabidopsis and Tomato by Plant Growth-Promoting Rhizobacteria
(2005-08-15)
Plant growth-promoting rhizobacteria (PGPR) were evaluated for induction of growth promotion in Arabidopsis and enhancement of stress tolerance in tomato under greenhouse and field conditions. Bacillus strain GB03 not only ...
Influence of Endosymbionts in Mediating Plant Defense Responses to Herbivory by the Pea Aphid, Acyrthosiphon pisum
