    Improved tobacco cultivars possessing alleles of the “va” recessive resistance gene have been deployed worldwide to mitigate consequences of potato virus Y (PVY) infections. Unfortunately, necrotic PVY symptoms were reported, suggesting that PVY is...

    The results of 1997 and 1998 field trial with air cured tobacco, comparing non-inoculated controls with mechanically inoculated plots, under conditions of low natural incidence of non persistent aphid-transmitted viruses, lead to the following...

    Assessment of the efficacy of CGA 245704 associated or not with CGA 329351 (metalaxyl-M) for the control of blue mold (P. tabacina): results of four years of experimentation

    SEITA, Institut du Tabac, Bergerac, France
    Since 1993, a stimulator of the plant's natural resistance (CGA 245704) or acibenzolar-S-methyl, belonging to the benzothiadiazole group, has been tested for blue mold ( P. tabacina ) control both on seedbeds and on the field. An application of CGA...

    Study of the virulence of PVY isolates on tobacco: proposal for a classification integrating the resistance to necrosis

    BLANCARD D.; ANO G.; CAILLETEAU B.
    INRA - Institut du Tabac, Bergerac, France
    Having collected 40 or so isolates of PVY found in tobacco in France their virulence has been evaluated in 6 genotypes of tobacco. In function of their comportment and especially their capacity to induce necrotic symptoms we have been able to...
