Taken up as ionic Sulphate SO4-, Sulphur links with Nitrogen to build protein and promote canopy development.
Function
Symptoms
Similar in appearance to Nitrogen stress, low Sulphur status induces a pale yellow chlorosis of the entire plant. Plants produce smaller leaves with lower chlorophyll and slower growth rates. Low Sulphur status can lead to elevated leaf concentrations of free Nitrogen, which can increase insect and disease pressure.
Significance
As mobility within the soil is very high, Sulphur demand is not often met without supplementation. Low Sulphur status will restrict plant response to Nitrogen, influencing growth rates, senescence and disease resistance. Sulphur stress is often worse in cold, wet, compacted soils.
Actions
Omex Sulphomex is a clear solution containing water soluble sulphur and nitrogen. Crops will respond immediately to applications of Omex Sulphomex and it will be rapidly absorbed by the plant.
Omex Sulphomex will supply the sulphur requirements for all crops and its use will avoid the unpleasant dust and caking characteristics of many elemental products
Omex SW8 is a silicon based wetter, designed to give enhanced uptake of foliar nutrients. In addition, when used at higher rates, it also supplies silicon to the crop. This can have a secondary effect of deterrence, which may affect a variety of pests such as aphids, red spider mite, thrips and whitefly.
