| ABSTRACT Corn is a cereal whose productivity can be reduced by various diseases which has recommended treatments for control. The objective of this study was to analyze copper, zinc, calcium and manganese products for the management of Pantoea ananatis, Puccinia polysora and Cercospora zeae maydis in second season corn, and interference in agronomic characteristics. Commercial products made of amino acid chelated with 15% calcium, 5% copper, 15% manganese and 10% zinc, at the doses of 0.5 kg ha-1, 0.3 L ha-1, 0.4 kg ha-1 and 1 L ha-1, respectively, a treatment with fungicide (20% azoxystrobin and 8% cyproconazole at 0.3 L ha-1 + 25% propiconazole at 0.4 L ha-1), and a treatment with water were assayed. The experiments were carried out under field... |

| ABSTRACT Due to the environmental impact generated using fungicides, new alternatives for disease control have been arising, such as the use of nutrients that may act on the development of certain pathogens or decrease the host susceptibility to diseases. The objective of this work was to verify if chelates of calcium, copper, manganese and zinc inhibit the germination of Puccinia sorghi, Cercospora sp. and Exserohilum turcicum spores. Two experiments were carried out: the first with agar-water culture medium, where the treatments and spores were placed at the same moment and the second using corn leaves as substrate, where treatments were administered zero, one, two, three, four and five hours after the spores are sprayed. Calcium, copper, manganese and... |

| Abstract Platanus, an arboreal and deciduous plant, is widely adapted and can be used for several purposes. Despite producing viable seeds, production of platanus seedlings usually occurs through vegetative propagation; cuttings are the best and most efficient source for obtaining seedlings. Although cuttings offer a practical and easy method to obtain seedlings in different vegetable species, they are influenced by several factors, both external and internal. The present study aimed to analyze the behavior of plantain cuttings planted in sand subjected to damage or no damage at the cuttings base, and planted at depths of 20 and 40 cm. Experiment was carried out at the experimental station of horticulture and protected cultivation of UNIOESTE-Brazil, in a... |
