    Commercial prototype topping system reduces mechanical transmission of Ralstonia solanacearum

    FORTNUM B.A.; PETERSON P.; GOODEN D.
    Clemson University, Dept. of Entomology Soils and Plant Sciences, Pee Dee REC, Florence, SC, USA
    Mechanical flower removal (topping) has played a major role in the spread of bacterial wilt in the southeastern USA. Once a topping blade removes a Ralstonia olanacearum infected flower the blade is contaminated with the bacterium and the pathogen can ...

    Genetic diversity in Ralstonia solanacearum and implications for mechanical transmission in tobacco

    PETERSON P.D.; FORTNUM B.A.; MILA A.
    Clemson University, Dept. of Entomology Soils and Plant Sciences, Pee Dee REC, Florence, SC, USA
    Mechanical flower and leaf removal (topping/harvesting) have a major role in the spread of bacterial wilt in the southeastern USA. Mechanical topping and harvesting can spread the pathogen rapidly from localized centers of infection throughout entire ...

    Potential applications of 'GM' technology in the production of tobacco for its traditional uses

    FORTNUM B.A.; PETERSON P.D.; DAVIES M.; CHAMBERS O.; THOMAS P.
    Clemson University, Dept. of Entomology Soils and Plant Sciences, Pee Dee REC, Florence, SC, USA
    The flue-cured and Burley tobacco industries have thus far relied solely on the intrinsic gene-pool of the tobacco plant itself for traits that enhance yield, disease resistance, leaf quality etc. Meanwhile, over the last 25 years the tobacco plant has ...

    Functional avrA gene in Ralstonia solanacearum can elicit a defense reaction in tobacco stem tissue to pathogenic strains

    FORTNUM B.A.; PETERSON P.D.; GOODEN D.
    Clemson University, Dept. of Entomology Soils and Plant Sciences, Pee Dee REC, Florence, SC, USA
    Bacterial wilt caused by Ralstonia solanacearum is an extremely damaging disease of flue-cured tobacco in the southeastern USA and can be spread mechanically on farm machinery. Tobacco roots contain naturally occurring resistance genes to the tomato ...

    Maleic hydrazide application can alter bacterial wilt severity based on application timing

    PETERSON P.D.; FORTNUM B.A.; GOODEN D.
    Clemson University, Dept. of Entomology Soils and Plant Sciences, Pee Dee REC, Florence, SC, USA
    Bacterial wilt caused by Ralstonia solanacearum is an extremely damaging disease of flue-cured tobacco in the southeastern USA. Mechanical transmission of R. solanacearum during flower (topping) and leaf (multipass harvester) removal has contributed ...

    Effects of film mulching on heavy metal contents in flue-cured tobacco

    CHEN QING-YUAN; SHANG SHENG-HUA; LU NING
    Tobacco Science Research Institute of Guizhou Province, Guiyang 550023, P.R. China
    To explore the measures for heavy metal control, the effects of film mulching on the contents of heavy metals in soil and flue-cured tobacco leaf were experimented in the field, where the soil was polluted by heavy metals, Cd, Pb, Hg and Cr. The results ...
