Developing Alternatives to Methyl Bromide: A Focus on Acrolein (2-Propenal)
(2008-05-15)
Methyl bromide, a soil fumigant with biocidal action, is used in agriculture to control weeds, fungi, bacteria, nematodes, and arthropods. Due to methyl bromide’s active role in atmospheric ozone depletion, its usage will ...
Development of a CRISPR/Cas9 gene editing system for Fusarium oxysporum and characterization of an extracellular superoxide dismutase and its contribution to pathogenicity on cotton
(2019-04-17)
The Fusarium oxysporum species complex (FOSC) is an important group of filamentous fungi that are able to infect both animals and plants. Based on its economic importance, an effort has been made to better understand the ...
Development of Behavior-semiochemical-based IPM Approach for Invasive Kudzu Bug, Megacopta cribraria (F.) (Hemiptera: Plataspidae)
(2019-07-11)
The kudzu bug, Megacopta cribraria (F.), is newly detected invasive pest insect native to Asia. Since the first detection in 2009, it has spread rapidly throughout the southeastern U.S. It has become a key pest of legume ...
Development of Root Hairs is aligned with the Tolerance Trait of Cotton against the Infections of Rotylenchulus Reniformis, Plant Parasitic Nematode
(2018-11-15)
Plant parasitic nematodes (PPN) are major cotton pathogens, causing the annual yield of up to 10 % annually. Lately, reniform nematode (RN, Rotylenchulus reniformis) has become a major threat to the cotton farming industry ...
