Conteúdo: |
A ferrugem asiática, que tem como agente etiológico o fungo denominado Phakopsora pachyrhizi, é considerada a principal doença da cultura da soja no Brasil, sendo responsável por perdas produtivas de até 90% em condições ideais para o seu desenvolvimento. Este informativo tem como objetivo sistematizar informações referentes à ferrugem asiática da soja,bem como ao seu manejo. As principais técnicas incluem o manejo cultural, químico e genético, os quais devem ser aplicado sem conjunto no combate à doença. Práticas de caráter preventivos são extremamente importantes e não devem ser ignoradas,devendo ser aplicadas em conjunto com a utilização de fungicidas, onde a mistura de ingredientes ati vos contribui para o manejo. |

Crop systems using cover crops affect soil physical, chemical, and biological attributes,
including aggregate formation. This work aims to evaluate winter cover crop species' effect
on soil total organic carbon, glomalin, and aggregation in areas with onion crops in a
no-tillage vegetable production system (NTVS) and conventional tillage system (CTS) for
eight years. The experiment treatments were: control, with natural vegetation(NV); black oats
(Avena strigosa); rye(Secale cereale);oilseed radish(Raphanus sativus);intercropped black
oats and oilseed radish; intercropped rye and oilseed radish; and a conventional tillage
systems area. A 33-year old adjacent secondary forest was evaluated as a reference for
undisturbed conditions. We assessed soil total organic carbon, total glomalin, and easily
extractable glomalin in three soil layers (0-5, 5-10, and 10-20 cm depth). Undisturbed
samples were used to quantify soil aggregate stability, aggregation indexes (weighted mean
diameter; geometric mean diameter), aggregate mass distribution (macroaggregates,
mesoaggregates), and macroaggregate carbon contents. The conventional tillage areas had the
lowest weighted mean soil aggregate diameter, geometric mean diameter, and
macroaggregate mass. Those areas also had the lowest bulk soil and aggregate organic carbon
contents and the lowest total and easily extractable glomalin. Winter cover crops' use resulted
in a 10% higher aggregate weighted mean diameter and geometric mean diameter. Areas with
cover crops had 13% higher organic carbon contents in aggregates and 17% higher
macroaggregate mass than conventional tillage areas. The highest values of total and easily
extracted glomalin occurred in plots with black oats. Winter cover crops, single or
intercropped, improved physical attributes of soils with onion crops under not-tillage
compared to conventional tillage areas. MenosCrop systems using cover crops affect soil physical, chemical, and biological attributes,
