Control of black shank disease on tobacco, caused by the pathogenic fungus Phytophthora parasitica var. nicotianae, needs an integral approach which includes: crop rotation, use of fungicides, nemathodes control, suitable agrotechnical measures and application of resistant varieties.
The metalaxyl based chemicals have the best effect in the root zone and near the stalk. Therefore, they should be applied in the control of tobacco from this disease by incorporation in soil prior to or immediately after transplanting. Fungicide Ridomil G5, which is in granulated form, should be applied on tobacco prior to transplanting, by scattering the granules in rows and their incorporation. Other fungicides (Metasan, Ridomil plus 48WP and Ridomil gold MZ68 WP), which are in a form of powder for suspension (WP), are dissolved in water first and then added by watering of the plants.
In our investigations, fungicides Ridomil G5 and Metasan applied in a rate of 2-3 kg/ha a.i. and Ridomil plus 48 WP in a rate of 4.0 kg/ha a.i. metalaxyl reached an effectiveness of over 90%.
