PACHECO, F.P.; NOBREGA, L.H.P.N.; TONINI, M.  e  CRUZ-SILVA, C.T.A.. Common bean seeds quality during storage under treatments with potential repellent of aromatic plants. Rev. bras. plantas med. [online]. 2016, vol.18, n.2, pp.473-479. ISSN 1516-0572.  http://dx.doi.org/10.1590/1983-084X/15_161.

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.
