The effectiveness of using biological preparations in the production technology for seed material of potatoes

Abstract

An integrated plant protection system must focus on the biologization of this process. Used phytohormones and phytofungicides have a biostimulating and fungicidal effect on potato plants. The biological products used to one degree or another increase the adaptogenic capabilities of plants. Biological preparations have provided a high level of immunity of potato plants to major diseases. The fungicidal properties of the preparations were well appeared. No increase in infection or spread was observed in experiments using biofungicides. To a greater extent, the preparations acted as prophylactic ones, preventing the penetration of the phytopathogen into plants. At the same time, there is a long period of suppression of its development, the formation of resistance to late blight. The immunostimulating effect of Zircon and Epin extra in relation to late blight is found to a lesser extent in comparison with the Trichodermin, Rizoplan and Baktofit biofungicides. The fungicidal action of these preparations proved to be highly effective.

Optimizing Potato Yield through the Application of the Supporter Biostimulant

“…Increased potato yields after the application of pre-sowing seed treatments have been observed in both domestic and foreign studies. Treating potato seed tubers with biological preparations, as reported by Orzaliyeva et al [47], enhances yield by accelerating the pace of plant growth and development, increasing the assimilation surface area, and boosting resistance to potato diseases. Research by Pytlarz-Kozicka and Zagórski [48] showed that the use of Trianum + Proradix WG and Proradix WG seed treatments increased both total and commercial potato yields compared to the control.…”
