Abstract(s)
Agricultura Biológica é um modelo capaz de dar resposta a um
desenvolvimento sustentável e a economia circular uma oportunidade para uma maior
eficiência e gestão de recursos naturais. Dois problemas agronómicos de relevo são
os nemátodes das galhas radiculares e as plantas espontâneas. A casca de fava é um
subproduto da indústria agroalimentar que poderá ser tido em consideração para o
combate destes. Neste estudo foram realizados ensaios, in vitro, para testar os efeitos
de extratos de vagem de fava, sem sementes, oxidada na mortalidade de jovens do
segundo estádio de Meloidogyne incognita bem como de extratos de vagem de fava,
sem sementes, oxidada e de hidrolatos na germinação e desenvolvimento de plantas
de Solanum lycopersicum, Rumex crispus e Cyperus rotundus.
Os resultados obtidos indicam que o extrato de fava a 10% é o melhor
potencial nematicida. No ensaio com hidrolatos, para testar a inibição de sementes
de Rumex crispus, os de Rosmarinus officinalis e Salvia canariensis apresentaram
melhor efeito inibidor da germinação e no ensaio em Cyperus rotundus verifica-se o
potencial promotor de Melaleuca alternifolia, Saponaria officinalis e
Solanum mauritianum.
Os efeitos obtidos devem ser tidos em conta numa visão mais sustentável no
controlo de inimigos das culturas agrícolas.

Organic Farming is a model capable of responding to a sustainable development and circular economy an opportunity for greater efficiency and management of natural resources. Two major agronomic problems are root twig nematodes and spontaneous plants. Bean peel is a by-product of the agri-food industry that can be taken into consideration to combat them. In this study, in vitro tests were carried out to test the effects of bean pod extracts, seedless, oxidised on the mortality of young people in the second stage of Meloidogyne incognita as well as of bean pod extracts, seedless, oxidised and hydrolats on the germination and development of plants of Solanum lycopersicum, Rumex crispus and Cyperus rotundus. The results obtained indicate that bean extract at 10% is the best nematicide potential. In the hydrolats assay, to test the inhibition of Rumex crispus seeds, those of Rosmarinus officinalis and Salvia canariensis showed better germination inhibitory effect and in the Cyperus rotundus assay the promoter potential of Melaleuca alternifolia, Saponaria officinalis and Solanum mauritianum is found. The effects obtained should be taken into account in a more sustainable view in the control of enemies of agricultural crops.
