Overwintering phytopathogens on potato tubers are the primary cause of late blight and scab. Agronomist and consultant Olga Semyonova recommends soaking tubers in biofungicides before planting to create an active protective barrier that suppresses fungal activity even before contact with the soil. While traditional options like Bordeaux mixture remain a budget standard, modern biological methods help reduce excessive chemical use. Preparations such as “Tetris,” “Trichoderma Veride,” and “Bakterra” colonize the tuber surface with beneficial microflora that displaces pathogens, thereby improving soil structure and ensuring stable results through smart farming practices.
In addition to fungal diseases, wireworms and Colorado potato beetles pose major threats to the harvest. Agrochemist Roman Edigaryev advises targeted application of systemic insecticides like “Tabu” or “Prestige,” ensuring even distribution over the tuber surface for protection during critical growth stages. For those preferring organic farming, planting legumes or mustard alongside potatoes is a proven method to disorient pests. Specialist Alexey Danilov warns that proper dosage is essential—skimping on products leads to pest resistance. A concentrated solution like “Drakor” can be applied to material laid out in the shade, and after the film dries, the tubers are ready for planting.
