    The present study aimed to evaluate the molluscicidal effect of plant extracts from Agave americana and Furcraea andina as biological alternatives for the control of Deroceras reticulatum (slugs) in strawberry (Fragaria ananassa) cultivation. The experiment was conducted in an established Albion variety strawberry crop in the Santa Rosa parish, Ambato canton. A completely randomized block design (CRBD), considering two plant extracts at two concentrations (25% and 50%), plus two controls (absolute and chemical), with three eplications per treatment. The evaluated variables were: number of dead slugs, and damaged fruits before and after treatment. Statistical analysis was performed using ANOVA and Tukey’s test at 5%. Results showed that the Agave americana extract at 50% (D1E2) was the most effective treatment, achieving the highest slug mortality at 30 days (8.33 individuals), with results comparable to the chemical control. However, all extracts showed a decrease in effectiveness at 45 days, indicating a limited residual effect. Regarding damaged fruits, no statistically significant differences were observed between treatments or evaluation times. It is concluded that the plant extracts, especially Agave americana at 50%, possess high molluscicidal potential in strawberry crops. Its use is recommended as an agroecological alternative, although further research on its persistence is suggested, along with combining it with other strategies to maximize effectiveness in reducing visible fruit damage
