Mixed Infection in Tomato Plants by Dominant Bacterial Spot Pathogen and the Co-occurring Bacterial Species
(2022-03-08)
Pathogen dynamics can be altered by co-occurring pathogenic or opportunistic entities inhabiting the same host species. Mixed infection or co-infection caused by multiple pathogenic strains are common in nature. However, ...
Toxicity and Physiological Effects of Essential Oil Components against the German Cockroach, Blattella germanica (L.) (Ectobiidae)
(2022-03-24)
The overarching goal of this research is to extend the scholarship on and provide new evidence that rationalizes the inclusion of low toxicity, plant-based essential oils (EOs), and their components (EOCs) into integrated ...
Community Dynamics of the Phyllosphere Microbiome
(2022-04-29)
The phyllosphere of a plant creates a complex niche for inhabiting microorganisms in which interactions will occur. The dynamics of the interactions between a foliar plant pathogen, Xanthomonas perforans, and the resident ...
Tools and Insights for Sustainable Management of Plant Pests and Pathogens
(2022-04-25)
Minimizing crop yield losses caused by plant pathogens is one way of increasing agricultural productivity. To that end, I developed an automated classifier of digital images of soybean diseases to assist with early and ...
Evaluation of Meloidogyne incognita and Rotylenchulus reniformis nematode resistant cotton cultivars with supplemental Corteva Agriscience nematicides
(2022-05-02)
Meloidogyne incognita (root-knot nematode) and Rotylenchulus reniformis (reniform nematode) accounted for an estimated 7% of the cotton yield lost in Alabama in 2020 and 7.5% lost in 2021. New nematode resistant cotton ...
Assessment of accessory genome and host-specific virulence in Fusarium
(2022-07-28)
Members of the Fusarium solani and Fusarium oxysporum species complexes (FSSC and FOSC, respectively) comprise soil borne filamentous fungi of clinical and agricultural importance. The main focus of this study is to study ...
Characterization of the mode of plant interactions with different environmental stress cues: drought and plant parasitic nematodes
(2022-07-28)
Plants are vulnerable to a variety of biotic and abiotic environmental stressors, which
suppresses and limits the growth and yield potential of agricultural crops. Recently, drought
has become one of most expensive abiotic ...
Antennal Responses, Repellency, and Toxicity of Essential Oil Formulations on the German Cockroach (Blattodea: Ectobiidae)
(2022-08-05)
The toxicity, repellency, and the electroantennogram responses induced by six essential oil formulations and their components against the pyrethroid-susceptible (S) and resistant (D and E) strains of the German cockroach, ...
The diversity of oomycetes associated with cotton seedlings in Alabama and the assembly of the spermosphere microbiome of cotton and soybean
(2022-11-21)
Cotton and soybean are major crops in the US grown for fiber and protein. Fungal and oomycete pathogens can affect cotton and soybean seedlings resulting in seed and seedling damping-off. Many different oomycete species ...
Sclerotinia sclerotiorum: Yield Loss of Brassica carinata in the Southeastern United States and Effect of Fungicides and Light Wavelength.
(2022-11-28)
Sclerotinia sclerotiorum is a major pathogen of over 400 plant species around the world and is considered to be the biggest threat to the production of Brassica carinata in the southeastern United States. Brassica carinata ...
