Avaliação do extrato vegetal de moringa no controle de fungos em sementes de milho

Abstract

Zea mays is one of the main and most important crops grown in Brazil, has a great social and economic importance, due to it’ s wide range of utilities, such as human and animal consumption. For a good production it’s fundamental that the companies present a high percentage of germination and vigor; In addition, it’s common for seeds with greater storage capacity, being one of the major causes of damage, which leads to a rapid deterioration of the seed, making your aura physiological. Currently the most widespread fungi control is the application of chemicals, but with the use of a cycle of contamination, bringing risks to the environment as a human health. The present work was carried out with the objective of evaluating the activity of the moringa seed extract (Moringa oleifera Lam.), as ingested in different dosages (0, 3, 6, 9 and 12 ml) as samples. Of seeds were stored in multifolium paper packages during the period of 90 days. The objective of this study was to analyze the effect of the extract on the physiological potential of the seeds, as evaluated through the tests of moisture, germination, electrical conductivity and mycoflora. The results obtained showed that the efficiency of the vegetal extract is higher when compared to the higher doses (9 and 12 ml), observed that the samples of seeds treated with a dosage of 12 ml showed a percentage of germination lower than the others, as others did not differentiate.
