    Istituto Sperimentale per il Tabacco, Scafati, Italy
    A greenhouse trial was carried out, during year 2000 and replicated in 2001, to evaluate lead distribution and accumulation in tobacco plants experimentally exposed to the heavy metal and to reveal possible differences depending on variety and or type, ...

    Selection of fungal isolates with antagonistic effect against Rhizoctonia solani (AG 4 and AG 2-1 Nt) and growth promotion on tobacco

    LAHOZ L.; NICOLETTI R.; PORRONE F.; RAIMO F.; COVARELLI L.; CONTILLO R.
    Istituto Sperimentale per il Tabacco, Scafati, Italy
    Plant disease control is dominated by an over-reliance on chemical pesticides, in order to increase yield and quality. Since at least the 1930s, fungi of several genus have been known to be able to control soil-borne pathogens. A number of isolates of ...

    Phosphate uptake of flue-cured tobacco on red soils with high phosphate sorption

    JANSEN A.
    ARC, Agricultural Research Council - Institute for Industrial Crops, Rustenburg, South Africa
    Red soils are known for their high phosphate sorption. Although the red soils of the Institute for Industrial Crops have a history of heavy fertilization, the phosphate content of tobacco grown on them remains relatively low. The reason is that the ...

    Host response of root-knot nematode resistant rotational crops to Paratrichodorus meyeri

    VAN BILJON E.R.; BOTHA M.S.
    ARC, Agricultural Research Council - Institute for Industrial Crops, Rustenburg, South Africa
    The reproductive potential of the stubby-root nematode, Paratrichodorus meyeri, was evaluated on cultivars of crops with resistance to Meloidogyne javanica and M. incognita races 2 & 4 in various experiments over a period of three years. P. meyeri is ...

    The efficacy of various chemicals and biological agents in the control of false broomrape (Agrobacterium tumefaciens) in flue-cured tobacco

    SWANEPOEL A.
    ARC, Agricultural Research Council - Institute for Industrial Crops, Rustenburg, South Africa
    False broomrape, caused by Agrobacterium tumefaciens, causes yield losses in flue-cured tobacco in South Africa. False broomrape causes typical grown gall symptoms in tobacco- tumours, variable in size, develop on the roots of infected plants. Several ...
