    Effects of planting dates, metalaxyl, and fenamiphos on the tobacco black shank-root knot complex, tobacco quality and yield

    CSINOS A.S.; MINTON N.A.; STEPHENSON M.G.
    University of Georgia, Dept. of Plant Pathology, Tifton, GA, USA.
    Tobacco transplanted 5 April tended to have a higher incidence of black shank disease than tobacco transplanted 5 May in 1983. The combination of metalaxyl and fenamiphos reduced black shank disease in both plantings over the untreated control....

    Effect of seedling source on incidence of tomato spotted wilt in flue-cured tobacco

    CULBREATH A.K.; BERTRAND P.F.; CSINOS A.S.
    University of Georgia, Dept. of Plant Pathology, Tifton, GA, USA.
    Tobacco seedlings from 16 different outdoor seedbeds in 11 counties in Georgia were assayed by ELISA for tomato spotted wilt virus (TSWV). Only one asymptomatic seedling out of more than 1,200 was positive for TSWV. Additional seedlings from the 16...

    Evaluation of an enzyme-linked immunosorbent assay for Phytophthora parasitica var. nicotianae in tobacco

    CSINOS A.S.; MILLER S.
    University of Georgia, Dept. of Plant Pathology, Coastal Plain Experimental Station, Tifton, GA, USA
    Diseased tobacco (Nicotiana tabacum L.) samples collected from a black shank nursery or commercial fields in 1988 and 1989 were used to compare enzyme-linked immunosorbent assay (ELISA) Phytophthora kits to standard culture plating identification...

    Mechanical properties of flue-cured tobacco lamina as related to maturity and stalk position descriptors of market grade

    FOUTZ T.L.; ABRAMS C.F.; SUGGS C.W.
    University of Georgia, Dept. of Biology and Agricultural Engineering, Athens, GA, USA.
    Market grades were determined on a leaf-by-leaf basis for flue-cured tobacco harvested in 1986 and 1987. The leaves were placed into categories that described stalk position and maturity as defined by the USDA's elements of quality. Uniaxial...

    Some effects of two methods of sucker control on flue-cured tobacco produced at three fertilizer levels

    STEFFENS G.L.; MILLER J.D.
    United States Department of Agriculture, and University of Georgia Agricultural Experiment Stations, Georgia Coastal Plain Experiment Station, Tifton, Georgia USA
    A field study was undertaken to determine the effects of maleic hydrazide (MH) on some of the chemical and physical properties of flue-cured tobacco produced at three fertilizer levels-4-8-12 at 1200, 1600, and 2000 lb/A. Data on sucker growth, leaf...

    Some effects of urea and maleic hydrazide on flue-cured tobacco

    HARRIS J.B.; MILES J.D.
    United States Department of Agriculture and University of Georgia Agricultural Experiment Stations, Georgia Coastal Plain Experiment Station, Tifton, Georgia USA
    A field experiment is described which showed the effects of urea and maleic hydrazide (MH-30) applied separately and in combination to flue-cured tobacco. Urea was applied as a foliar spray at the rate of a pound of nitrogen per 1000 plants and MH-30...
