Summary: | ABSTRACT ndustrial chemicals that control pests in stored seed can cause damage to health by residual effects remaining in the grains. Studies of products with potential insecticide and repellent properties are required to decrease post-harvest losses. Thus, the aim of this study was to evaluate the quality and efficiency of seed treatment in beans stored under the following treatments: dried leaves and crushed laurel (Laurus nobilis L.), rosemary (Rosmarinus officinalis L.) and basil (Ocimum basilicum L.), cinnamon powder (Cinnamomum zeylanicum Breyn) and ground cloves (Syzygium aromaticum L.) over eight months. An untreated control and a treatment with diatomaceous earth were used to compare the results. At the beginning and at 30 days, percentages of normal and abnormal seedlings as well as seeds that did not germinate, mass of onehundred seeds, water content and infested seeds were analyzed. At 210 and 240 days, free choice arena and repellency testswere conducted. Treatments did not affect germination, mass of 100 seeds or water content; however, all plants tested showed a repellent effect on the bean weevil.
RESUMO Produtos químicos industriais que controlam pragas de sementes e grãos armazenados podem causar danos à saúde pelo efeito residual que proporcionam. Assim, são necessários estudos de produtos que apresentem repelência e potencial inseticida e reduzam perdas pós-colheita sem causar danos à saúde. Neste contexto, o objetivo deste trabalho foi avaliar a qualidade e eficiência do tratamento com plantas aromáticas: folhas desidratadas e moídas de louro (Laurus nobilis), alecrim (Rosmarinus officinalis) e manjericão (Ocimum basilicum L.), canela em pó (Cinnamomum zeylanicum Breyn) e cravo moído (Syzygium aromaticum L.), em sementes de feijão carioca armazenadas durante oito meses. Uma testemunha sem tratamento e outra com terra de diatomáceas foram utilizadas para comparação dos resultados. No início e a cada 30 dias foram realizadas as determinações de plântulas normais, anormais, sementes não germinadas, massa de cem sementes, teor de água e sementes infestadas. Os testes de arena de livre escolha e repelência foram realizados aos 210 e 240 dias. Os tratamentos não influenciaram a germinação, massa de cem sementes, teor de água. Entretanto, todas as plantas testadas apresentaram efeito repelente sobre o caruncho do feijão. |
