| Abstract Lime sulphur is used worldwide in agriculture to control pests and diseases. Our objective was to determine the effect of lime sulphur applications in an orange orchard on soil chemical properties and foliar nutrients after seven years of use to control B. yothersi. Soil and leaf samples were collected in two consecutive years for determination of soil chemical properties and nutritional analysis, respectively. We also assessed severity of citrus leprosis and productivity of plants. The applications of lime sulphur reduced pH values in CaCl2 and increased levels of S-SO42- in subsurface soil layer. Plants treated with lime sulphur had thehighestleaf concentrations of Ca and S and of the micronutrients B, Cu, Mn e Zn. On the other hand, lime... |
