Yield, volume, quality, and reduction of biotic stress influenced by titanium application in oilseed rape, winter wheat, and maize cultivations

The study presents the results of research on the influence of a mineral growth stimulant containing titanium (Ti) in the form available to plants, applied to reduce the effects of biotic stresses caused by agrophages, namely fungal pathogens and selected insect pests. The study was conducted in 2014 and 2015 on winter oilseed rape, winter wheat, and maize. The purpose of the study was to determine the influence of the Ti containing stimulant on the degree of damage caused by major pests occurring in the crops (cabbage seed weevil, cereal leaf beetle, and European corn borer), the degree of infestation with fungal diseases (gray mold, Alternaria disease, eyespot, foot rot, sooty mold, glume blotch, Fusarium head blight, Fusarium stalk rot, maize smut, and brown spot), and yield parameters. The study showed that the stimulant containing Ti successfully reduced the occurrence of pest damage to winter rapeseed and winter wheat plants and the occurrence of diseases in winter rapeseed, winter wheat, and maize crops. Thus, the application of the Ti stimulant resulted in an increased yield of the crops being tested. The main factor explaining this phenomenon is unknown, and it is probably the result of several factors. The study contains the discussion on this phenomenon.
