The study aimed to validate the efficiency and effectiveness of baculovirus BT viral powder in the prevention of damage caused by moths in seed potato tubers, effectiveness for the development of healthy sprouts of stored potato with rational loss of weight after storage in the province of Acobamba. The work developed was scientific, referred to the storage of seed potato, evaluation of the threshold of damage caused by the presence of moths, had a population of 450 seed potato tubers Yungay variety. The level of investigation was experimental. As a result, the highest percentage of damage to seed tubers, deterioration of sprout size, lower average weight of tubers after storage and higher population of moth larvae in sprouts and tubers were unfavorably manifested when the seed tubers were stored traditionally, being less the effects in those stored with "hydrated magnesium silicate": Mg3 SiO10 (OH)2 and Talc BT, standing out those that were impregnated with Talc "hydrated magnesium silicate" the greatest protection against moths was the intense white color of the product lodged in the eyes and skin of the seed tubers unlike Talc BT. Finally, post storage (120 days), seed potato tuber weight loss of 73.33% for T3 (control), 47.78% for Talc BT and 47.21% for Talc "magnesium silicate hydrate" which economically causes a loss/ha. of seed for T3 (control) of S/. 1199.93 soles (density: 22727 tillers / ha., 1363.62 kg. of seed tuber / ha.).
