Brazilian Students Develop Castor Bean-Based Natural Insecticide to Combat Crop Pests
Students in Barra da Estiva create a natural insecticide from castor bean to help family farmers combat pests sustainably.
- • Brazil suffers over R$ 60 billion in agricultural losses annually due to pests.
- • Students from Barra da Estiva developed a castor bean-based insecticide for lettuce crops.
- • Tests showed treated lettuce had better growth and less pest damage.
- • The project supports family farmers and promotes sustainable farming practices.
Key details
In Barra da Estiva, Brazil, a group of students from Colégio Estadual de Tempo Integral Professora Ana Lúcia Aguiar Viana has developed a natural insecticide derived from castor bean (Ricinus communis) aimed at controlling pests in lettuce cultivation. Agricultural losses in Brazil due to pests exceed R$ 60 billion annually, motivating students Caíque Santos, Amanda Santos, and Larissa Freitas to seek sustainable pest control solutions that could benefit family farmers.
Inspired by conversations with local farmers facing challenges with pests such as ants and caterpillars, the students, under the guidance of teacher Joseane Morais, conducted field research and formulated a castor bean-based insecticide. Controlled tests revealed that lettuce treated with this insecticide showed improved quality, better growth, and significantly less pest damage compared to untreated plants.
The project has gained recognition at the Student Meeting organized by the state Secretary of Education and aims to expand its applications in sustainable agriculture. Farmers from the Fazenda Capão do Cipó community have already expressed interest in utilizing the natural insecticide to protect their crops. This initiative exemplifies innovative, student-led efforts to address agricultural pest challenges while promoting eco-friendly alternatives in Brazilian family farming.
