Abstract
Foliar fertilizers provide a supplemental nutrition of crops with macro- and microelements stimulating their growth and development. Our earlier studies showed that amino acid-based biostimulator Izabion provides a significant increase in the yield and quality of potato. In this study, several different schemes of the Izabion application separately and combined with fungicide preparations were tested under field conditions to evaluate its contribution to these two parameters, as well as to reduction of crop losses caused by foliar diseases. Based on the obtained results, the optimum scheme of the Izabion application was determined. Izabion did not significantly influence on the yield losses caused by leaf blights of potato (biological efficiency was only 10.5% that excludes any protective effect), but increased the fraction of marketable potatoes by 13–16% due to its stimulating effect on plants under biotic stress. Combining Izabion with standard variants of chemical protection provided an additional yield increase by 2.0–3.8 t/ha comparing to chemical protection only; the biological efficiency of such combined protection reached 93.5–97.7%. The most efficient protection variant (foliar application of Izabion, pre-planting fungicide treatment of tubers, and standard chemical protection scheme) showed the maximum biological efficiency (99.6%) and resulted in the maximum marketable fraction of potatoes (95%) and the maximum yield increase (15 t/ha) comparing to the untreated control. Thus, a triple spraying of plants with Izabion during a vegetation season is recommended in addition to the standard protection schemes.
