Sobre IBD

Há quase cinco milénios que a soja alimenta milhões de pessoas, mas continua a ser vulnerável aos nemátodos das galhas (Meloidogyne spp.), que são pragas formidáveis. Face a este flagelo, a utilização maciça de pesticidas químicos está a prejudicar a saúde e o ambiente. Este livro explora os pesticidas orgânicos como uma alternativa sustentável e económica. O estudo, realizado em Kinshasa (comuna de Mont-Ngafula) utilizando um desenho de blocos completos aleatórios, comparou quatro tratamentos: extractos de Euphorbia tirucalli, folhas frescas de Panicum maximum enterradas no solo, o nematicida químico Nema B2 e um controlo sem proteção. Os resultados mostram que o extrato de E. tirucalli e o Nema B2 reduzem significativamente o índice de galhas (0,4 e 0,3), enquanto o P. maximum e a testemunha apresentam índices mais elevados (1,05 e 1,65). Para além de protegerem contra as pragas, estas soluções biológicas melhoram o crescimento e o rendimento, oferecendo aos agricultores um meio eficaz de produção sustentável.
