Summary: | The aim of the research was to analyze the degree of infection of winter wheat by fungal
diseases and to evaluate the morphological and physiological parameters of plants
depending on varied foliar fertilization (with and without the ionic form of silver) and
applied plant protection agents (active ingredients: propiconazole, fenpropidin, azoxystrobin)
in the 2016/2017, 2017/2018 and 2018/2019 growing seasons. The results showed
that micronutrient fertilizers with silver and pesticides reduced the severity of fungal
diseases better than the control. In most cases, foliar fertilizers enriched with the ionic form
of silver at a dose of 1 and 2 l · ha−1 were the most effective. Moreover, foliar fertilization and
pesticides had a positive effect on the morphology of wheat. Combined treatment (micronutrient
fertilizer with silver and pesticide at a dose of 1 l · ha−1) increased stalk length and
weight, ear weight and thousand grain weight to the greatest extent in comparison to the
other treatments, while the pesticides stimulated ear length the most. In turn, microelement
fertilizers with silver at a dose of 1 and 2 l · ha−1 were better in terms of flag leaf length.
Wheat treated with foliar fertilizer and pesticide significantly improved the chlorophyll
content based on the leaf greenness index (SPAD). It was found that the foliar application
of microelements with silver is promising for use in agriculture because they controlled
fungal diseases and ensured the good condition of plants more effectively than pesticides
harmful to the environment. |
