Influence of silicon-containing rock on keeping of potatoes

In field experiments, the effect of treating potatoes with diatomite (Inzenskoye deposit of the Ulyanovsk region of the Russian Federation) at doses of 40 and 60 kg/ha and Rizoplan (1 l/t) was studied. When laying potatoes for storage, dusting with zeolite (Tatarsko-Shatrashanskoye field of the Republic of Tatarstan) was carried out at the rate of 10 kg per ton of tubers. Before and after storage, tubers were compared to infection with late blight, fusarium, soft rot and the development of gray spot. During storage, it was noted that it was the pre-treatment of plants with diatomite (60 kg/ha) that suppresses late blight, fusarium and gray spotting. The absence of wet rot was noted during the treatment of plants with Rizoplan and diatomaceous earth. It has been established that dusting tubers with zeolite is a promising technique for the preservation of potatoes.
