    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 time ...

    Incidence and survival of Ralstonia solanacearum on tobacco mechanical toppers and harvesting equipment

    FORTNUM B.A.; KLUEPFEL. D.
    Clemson University, Pee Dee REC, Florence SC, USA
    Bacterial wilt (Ralstonia solanacearum) is an extremely damaging disease of flue-cured tobacco in North and South Carolina. It is generally believed that infection of tobacco in the field occurs through the root system. The rapid spread of bacterial wilt ...
