    Harvester modification to reduce mechanical transmission of R. solanacearum

    FORTNUM B.A.; PETERSON P.D.
    Clemson University, Department of Entomology Soils and Plant Sciences, Pee Dee Research and Education Center, Florence, SC, USA
    Mechanization both in leaf (multipass harvester) and flower (topping) removal has contributed to the spread and severity of bacterial wilt in North and South Carolina. When a mechanical harvester removes an infected leaf the bacterium can contaminate...

    The use of maleic hydrazide to suppress mechanical transmission of Ralstonia solanacearum during leaf removal

    PETERSON P.D.; FORTNUM B.A.; REED T.D.
    Clemson University, Pee Dee Research & Education Center, 2200 Pocket Road, Florence, SC 29506, USA
    Bacterial wilt disease caused by Ralstonia solanacearum is a major limiting factor in the successful production of flue-cured tobacco in the southeast U.S.A. Mechanical transmission of the bacterium during flower and leaf removal plays a significant...

    Functional avrA gene in Ralstonia solanacearum can elicit a cross protection reaction in mechanically transmitted bacterial wilt

    FORTNUM B.A.; PETERSON P.D.; ROBERTSON A.; GOODEN D.T.
    Dept. of Entomology, Soils and Plant Sciences, Pee Dee Research and Education Center, Clemson University, Florence, SC 29506 USA
    Bacterial wilt caused by Ralstonia solanacearum is an extremely damaging disease of flue-cured tobacco and can be spread mechanically on farm machinery. Tobacco roots contain naturally occurring resistance genes to the tomato strain of R....

    Maleic hydrazide application alters bacterial wilt severity in mechanically topped and harvested tobacco

    PETERSON P.D.; FORTNUM B.A.; GOODEN D.T.
    Dept. of Entomology, Soils and Plant Sciences, Pee Dee Research and Education Center, Clemson University, Florence, SC 29506 USA
    Bacterial wilt caused by Ralstonia solanacearum is a highly destructive disease of flue-cured tobacco. Mechanical transmission of R. solanacearum during flower and leaf removal contributes significantly to the spread and severity of bacterial wilt...

    Mechanical transmission of Ralstonia solanacearum is limited by air temperature

    FORTNUM B.A.; PETERSON P.D.
    Clemson University, School of Agriculture, Forestry and Environmental Sciences, Pee Dee Research and Education Center, Florence, SC, USA
    Bacterial wilt, caused by Ralstonia solanacearum, is an extremely damaging disease of flue-cured tobacco in the southeastern USA that can be spread mechanically on farm machinery. R. solanacearum exhibits strong tissue-specific tropism within the...

    Bacteriophage can reduce Ralstonia solanacearum induced stem necrosis in tobacco

    FORTNUM B.A.; PETERSON P.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 south-eastern USA and can be spread mechanically on farm machinery. Rolastonia solanacearum exhibits strong tissue-specific tropism within...

    The effect of growth regulators on the mechanical transmission of bacterial wilt

    PETERSON P.D.; FORTNUM B.A.
    Clemson University, Dept of Entomology Soils and Plant Sciences, Pee Dee REC, Florence, SC, USA
    Mechanical transmission of Ralstonia solanacearum during flower and leaf removal has contributed significantly to the spread and severity of bacterial wilt of tobacco in the south-eastern USA. Mechanical topping and harvesting also coincide with the...
