“…Treating seeds with fungicides is an important measure in protecting seeds during storage, and it may ensure an adequate population of plants and their good development after sowing (Zorato and Henning, 2001). Araujo et al (2019) also observed improvements in the physiological quality of castor bean seeds chemically treated with Derosal and Vitavax-Thiram compared to those without treatment at 12 months of storage. Ribeiro et al (2018) studied alternative treatments for conserving arabica coffee seeds and found that seeds treated with the chemical product mancozeb had root length superior to that of the seedlings obtained from seeds without any treatment over a 15-month storage period.…”

Maintaining the health of coffee seeds is especially important during storage, as soil fungi and storage fungi can considerably reduce seed quality. Thus, chemical treatments for protection of seeds in storage becomes important in agricultural production. It is necessary to evaluate the effects of these treatments on seedling development and the protection they provide against storage fungi, aiming at seed longevity and preventing rapid deterioration. The aim of this study was to evaluate the effect of chemical treatment on the physiological and sanitary quality of stored coffee seeds. Seeds of five Coffea arabica cultivars were pre-dried, treated with Vitavax®-Thiram, and placed in cold storage at 10 °C for nine months. Seed physiological quality was evaluated every three months by the germination test and by determination of root emergence percentage, seedlings with expanded cotyledonary leaves, and seedling dry matter. Seed health quality was assessed by the health test. The chemical treatment with Vitavax-Thiram does not affect the physiological quality of stored Coffea arabica seeds. Seed treatment before storage is effective in reducing the inoculum potential of Fusarium spp. and Phoma spp. in coffee seeds.

RESUMO Resumo: Objetivou-se estudar o efeito de tratamentos químico e alternativos e do ambiente de armazenamento na qualidade de sementes de pinhão-manso. As sementes foram submetidas aos seguintes tratamentos: produtos fungicidas, ambiente de armazenamento e tempo de armazenamento. Foram avaliadas as qualidades fisiológica e sanitária das sementes. Sementes tratadas com Carbendazin+Thiram apresentaram menor infestação de patógenos e germinação e vigor superiores àquelas tratadas com produtos alternativos ou sem tratamento, quando armazenadas por 12 meses, em câmara fria. Em câmara fria, os tratamentos alternativos que tiveram melhor desempenho foram alecrim, canela e cravo. Armazenadas em laboratório, aos oito meses, os melhores desempenhos das sementes, quanto à germinação e ao vigor, ocorreram quando foram tratadas com Carbendazin+Thiram, alecrim, canela e cravo; nessas condições, após 12 meses, houve queda drástica na qualidade fisiológica das sementes de todos os tratamentos. Os tratamentos alternativos mais promissores foram com alecrim, canela e cravo.
