Abstract
A three-year-long experiment was conducted to study the possibility of reducting stem base diseases for winter triticale growing in monoculture on light soil under conventional and reduced tillage. Two types of regenerative practices were used: ploughing down stubble crop (white mustard) and addition of Latitude 125 FS to standard seed dressing with Raxil 060 FS. The experiment was carried out in 2000–2003 on good rye complex of the soil. Varying methods of postharvest and pre-sowing soil tillage were used: 1) conventional and reduced post-harvest tillage with application of unselective herbicide Roundup 360 SL and with ploughing down stubble crop (white mustard); 2) conventional or direct sowing. A significant reduction of stem base diseases was found after addition of Latitude 125 FS to standard seed dressing with Raxil 060 FS. Ploughing down stubble crop did not reduce infestation of triticale by stem base diseases. Simplification in post-harvest tillage under conventional sowing significantly decreased infestation of triticale roots, but it did not affect infestation of stems. Direct sowing promoted more severe plant infestation with stem base diseases.
