Fusarium wilt of cotton is a serious fungal disease caused by Fusarium oxysporum f. sp. vasinfectum (FOV) and highly impacted by root-knot nematode (Meloidogyne incognita). Cotton cultivars were tested for resistance to ...

The diversity of oomycetes associated with cotton seedlings in Alabama and the assembly of the spermosphere microbiome of cotton and soybean

Olofintila, Oluwakemisola (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 ...

The effect of Sirex spp. woodwasps and their fungal associates on Alabama forest health

Wahl, Andrea (2017-04-20)

Forestry is an industry in the Southeastern United States that provides products and jobs to people throughout the region. These forests, while are mostly well managed for various outcomes, are susceptible to a variety of ...

Entomopathogenic Nematode Management of Small Hive Beetles (Aethina tumida) in Three Native Alabama Soils Under Low Moisture Conditions

Sanchez Soler, WinDi (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 ...

Evaluation of Meloidogyne incognita and Rotylenchulus reniformis nematode resistant cotton cultivars with supplemental Corteva Agriscience nematicides
