Svetlana, 37 years old:
“When I examined the potatoes, I found rot. I studied the characteristics of diseases, I realized that tubers are affected by Fusarium. As a result, part of the crop had to be thrown away. I think the losses are due to the fact that I didn’t process the potatoes before putting them into storage. ”
