The Effect of Cover Crops on Suppression of Nematodes on Peanuts and Cotton in Alabama
(2008-12-15)
Cover crops were evaluated in the greenhouse and in field locations to determine their host status and nematode suppressive effect on root-knot nematodes, Meloidogyne incognita and M. arenaria and the reniform nematode, ...
Effect of Microbial Inoculation on Nitrogen Plant Uptake and Nitrogen Losses from Soil and Plant-Soil Systems
(2013-12-04)
Reducing the negative impacts of agricultural fertilizers is a world-wide concern, both from an environmental and human health perspective. One way to reduce these impacts is by enhancing plant uptake, which improves ...
Effect of Rhizobacteria on Induction of Volatile Organic Compounds and Consequences for Corn Herbivores and Tritrophic Interactions
(2017-11-30)
Herbivorous insects depend on plants for survival. When herbivores feed on a plant the immobile plant responds directly by mobilizing it defenses, or indirectly by attracting natural enemies of the herbivore. Although plant ...
The effect of water stress on peanut soil microbiome and plant physiology
(2023-07-25)
Arachis hypogea is an economically important crop in the Southeastern region of the United States. The kernel has a high nutritional value containing oil, proteins, and carbohydrates. However, 90% of farmers in Alabama do ...
The Effects of Farmscaping Plants on the Abundance, Diversity, and Longevity of Arthropods in Organic Tomato Fields in Alabama
(2010-04-09)
Organic farming is the practice of cultivating crops without the use of synthetic pesticides or fertilizers. Farmscaping is habitat manipulation system of planting plants near the crop to attract beneficial insects by ...
The effects of herbivory on plant mating systems
(2005-12-15)
Inbreeding is common in many plant species. Inbreeding reduces heterozygosity and increases the expression of recessive deleterious alleles that cause inbreeding depression. The level or intensity of inbreeding depression ...
Effects of neonicotinoid exposure on the strength of honey bee (Apis mellifera) colonies
(2021-03-11)
A growing body of research continues to document and describe the unintended effects of insecticides on non-target organisms, such as insect predators, parasitoids, and pollinators. Specifically, different classes of ...
Effects of Plant Growth-Promoting Rhizobacteria (PGPR) Treatment of Cotton on the Oviposition Behavior of Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae)
(2012-03-29)
Treating crops with a group of naturally-occurring root bacteria, termed plant growth-promoting rhizobacteria (PGPR), has been shown to increase plant growth and enhance plant health in different ways. Although much is ...
Effects of Toxicants, Temperature, and Resistance on Metabolism and Gas Exchange Patterns of the Beet Armyworm, Spodoptera exigua (Hübner), and the German Cockroach, Blattella germanica (Linnaeus)
(2005-08-15)
Components of the respiratory physiology and water relations of Bacillus thuringiensis Cry1C resistant and susceptible beet armyworms, Spodoptera exigua, and pyrethroid resistant and susceptible German cockroaches, Blattella ...
Enhancing plant growth, drought stress tolerance, and biological control capacities of PGPR strains with exogenous pectin-rich amendments
(2020-06-15)
Bacillus velezensis is a plant growth-promoting rhizobacterium (PGPR) that promotes plant growth, enhances drought stress tolerance, and suppresses plant pathogens. However, little is known about the effects of exogenous ...
Entomopathogenic Nematode Management of Small Hive Beetles (Aethina tumida) in Three Native Alabama Soils Under Low Moisture Conditions
(2020-07-17)
The overall goal of this work was to determine the efficacy of entomopathogenic nematodes (EPNs) on Aethina tumida Murray (Coleoptera:Nitidulidae) small hive beetle (SHB) in different soil types under low moisture conditions ...
Epidemiology of Sclerotinia sclerotiorum, causal agent of Sclerotinia Stem Rot, on SE US Brassica carinata
(2020-04-16)
Brassica carinata is a non-food oil seed crop currently being introduced to the Southeast US as a winter crop. Sclerotinia sclerotiorum, causal agent of Sclerotinia Stem Rot (SSR) in oilseed brassicas, is the disease of ...
Epidemiology of target spot of cotton and tomato
(2017-11-28)
Target spot is a foliar disease of cotton caused by Corynespora cassiicola. This disease was first reported in Alabama in 2011. The overall goal of this study was to address the epidemiology of the target spot of cotton ...
Evaluating the effects of novel application methods of oxalic acid on Varroa destructor and Apis mellifera in the Southeastern United States
(2020-11-16)
Varroa destructor is a devastating ectoparasitic mite of Apis mellifera honey bees. To manage it, beekeepers employ Integrated Pest Management, including the strategic use of chemicals like oxalic acid. Here, I performed ...
Evaluating the effects of soil tillage on ground nesting bees in the southeastern United States
(2023-12-04)
Pollination by native bees is an economically and ecologically valuable service, necessary in both agricultural and natural landscapes. The majority of bee species nest below ground, an aspect of their biology that raises ...
