    Effects of time and rate of systemic suckercide application on growth, quality, and chemistry of upper-stalk flue-cured tobacco

    PEEDIN G.F.; HARRELL N.E.; FISHER L.R.; PRIEST J.A.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, USA
    The systemic suckercide, maleic hydrazide (MH), is the most widely used pesticide on flue-cured and burley tobacco produced in the USA. The dinitroanilines (DNAs), flumetralin and butralin, are also systemic suckercides that have become more widely used ...

    Time of maleic hydrazide application affects growth and agronomic properties of upper stalk flue-cured tobacco

    PEEDIN G.F.; HARRELL N.E.; PRIEST J.A.; FISHER L.R.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, USA
    Maleic hydrazide (MH) is the most widely used pesticide on flue-cured and Burley tobacco grown in the United States. The dinitroanilines, flumetralin and butralin, are also systemic suckercides and have become popular in recent years, particularly in ...

    Effects of sulfentrazone placement in the soil on phytotoxicity to flue-cured tobacco (Nicotiana tabacum)

    FISHER L.R.; SMITH W.D.; PEEDIN G.F.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, USA
    Sulfentrazone (Spartan 75 DF) is a relatively new herbicide in flue-cured tobacco production in the US. It provides excellent control of several of the most troublesome weeds in the US and worldwide including Ipomoea sp., and Cyperus sp. Crop injury has ...

    Fertilization of flue-cured tobacco with liquid nitrogen sources containing relatively high concentrations of ammonium N

    PEEDIN G.F.; PRIEST J.A.; SORENSON C.E.
    North Carolina State University, Dept. of Soil Science, Raleigh, NC, USA
    Flue-cured tobacco growers in the USA are constantly seeking more efficient production practices which reduce production costs without adversely affecting leaf quality. Less expensive but commonly available liquid N sources derived from urea and ammonium ...

    Response of four flue-cured tobacco cultivars to seed priming under differing environmental conditions

    HARTLEY M.D.; SMITH W.D.; FISHER L.R.; PEEDIN G.F.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, USA
    Three experiments were conducted in 1999 to determine the response of four flue-cured cultivars to seed priming. Experiments were conducted in tobacco transplant greenhouse (float systems) at two locations (Raleigh, NC and Waynesville, NC) to determine ...

    Effects of nozzle sizes and application speeds on sucker control with suckercides requiring stalk rundown

    PEEDIN G.F.; PRIEST J.A.; SMITH F.A.; RIDDICK M.G.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, USA
    Suckercide applications to flue-cured tobacco in the USA are made primarily with power sprayers. Except for maleic hydrazide (MH) applied alone, all other suckercides used alone or in combination require stalk rundown and subsequent contact with axillary ...

    Response of several flue-cured tobacco cultivars to seed priming

    SMITH W.D.; FISHER L.R.; SPIVEY B.M.; PEEDIN G.F.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, USA
    Three experiments were conducted in 1998 to deternine the response of four flue-cured tobacco cultivars to seed priming. Experiments were conducted in tobacco transplant greenhouses (float systems) at two locations (Raleigh, NC and Duplin County, NC) to ...

    Effects of nitrogen rate and ripeness at harvest on some agronomic and chemical characteristics of flue-cured tobacco

    PEEDIN G.F.; TUCKER M.A.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, USA
    Field experiments were conducted at two locations for two years and tobacco plots were supplied with three N rates (suggested N, suggested N-22 kg/ha, suggested + 22 kg/ha). Subjective degrees of ripeness at harvest were 7-10 days underripe, ripe, and 7 ...

    Effect of physical properties of soilless media on seedling production in the float system

    SMITH W.D.; HARRELL H.E.; PEEDIN G.F.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, USA
    Four greenhouse experiments were conducted in 1994 and 1995 to evaluate the effects of physical properties of soilless media on seedling production in the float system. Ten media were prepared in 1994 and five in 1995, from various combinations of peat, ...
