The problem of infestation of maize (Zea mays) grain with mycotoxins,
in the view of particular agroecological conditions, i.e. simplified tillage,
chemical protection against weeds, require continuous and profound research.
The aim of the research carried out in 2008–2010 was to determine the effect
of weed infestation on the increased occurrence of fungus diseases
in two maize cultivars depending on the used simplified tillage systems and determination
of the level of mycotoxins in tested grain cultivars. Poor efficiency of the rimsulfuron
herbicide, applied in combination with an adjuvant, as well as decreased tolerance
of SALGADO cultivar to that chemical compound were the cause of the following
disadvantageous phenomena: increased weed infestation with Echinochloa crus-galli (L.)
P. Beaur., Chenopodium album L. and Artemisia vulgaris L.,
more considerable grain infestation with fungi of F. culmorum and F. avenaceum
species, significant decrease in grain yield size and elevated level of deoxynivalenol
(2.648 mg·kg-1) and zearaleon (0.273 mg·kg-1)
mycotoxins in grain as compared to the not treated object and to BLASK cultivar,
especially in simplified tillage.
Key words: simplified tillage, weed infestation, Fusarium oxysporum, F. culmorum, F. avenaceum, deoxynivalenol, nivalenol, zearalenone.
