    North Carolina State University, Dept. of Plant Pathology, Raleigh, NC, USA
    In 1979 there was a major field epidemic of blue mold disease on tobacco in North America. Since 1979, smaller epidemics of blue mold have occurred every year in the field in the United States. Although there is no evidence that blue mold disease can be ...

    Sensitivity of Peronospora tabacina isolates to metalaxyl and dimethomorph in North Carolina, 1991-1999

    SHOEMAKER P.B.; MILKS D.C; MAIN C.E.
    Mountain Horticultural Crops Research and Extension Center, Fletcher, NC, USA
    Blue mold has occurred each year on North Carolina's Burley tobacco crop since the major epidemic of 1979. We began collecting and monitoring Peronospora tabacina isolates from North Carolina in the mid- 1980's, and have tested their sensitivity ...

    Modeling the long-range transport of the sporangiospores of Peronospora tabacina using the Mesoscale Atmospheric Simulation System (MASS model)

    MAIN C.E.; THURMAN J.A.; DAVIS J.M.; WAIGHT K.T.
    North Carolina State University, Dept. of Plant Pathology, Raleigh, NC, USA
    The Mesoscale Atmospheric Simulation System (MASS model) was used to simulate the transport of Peronospora tabacina spores. The model-forecast position of the dispersing spore cloud was compared with ground truth disease reports and meteorological data ...

    Experimental results with Actigard (CGA-245704) for blue mold in North Carolina, U.S.A

    SHOEMAKER P.B.; MAIN C.E.
    North Carolina State University, Dept. of Plant Pathology, Raleigh, NC, USA
    Actigard (CGA-245704) was evaluated for blue mold (Peronospora tabacina) control on Burley tobacco in replicated field experiments at research stations located at Waynesville, NC, in 1995 and 1996 and at Laurel Springs in 1996. Blue mold disease levels ...

    Nicotiana Spp. in Western U.S.A., a source of airborne inoculum for blue mold epidemics

    MAIN C.E.; SPURR H.W.
    North Carolina State University, Dept. of Plant Pathology, Raleigh, NC, USA
    Blue mold epidemics in the U.S. usually are initiated by showers of airborne spores from infected fields and wild populations in the Caribbean and Mexico. Wild Nicotiana spp. growing in the southwestern and western U.S. also represent important source ...

    Evaluation of susceptibility to blue mold in different Burley tobacco varieties and control with Acrobat MZ

    SHOEMAKER P.B.; MAIN C.E.
    North Carolina State University, Dept. of Plant Pathology, Raleigh, NC, USA
    Fourteen Burley tobacco varieties were evaluated for blue mold susceptibility in a replicated field experiment at the Upper Mountain Research Station, Laurel Springs, NC, in 1996. The experiment was duplicated in two separate sections. One section was ...
