Sulphur plays a crucial role in various aspects of plant development, such as maintaining plant structure and function, sustaining adequate levels of sulphur for overall plant health and productivity. The sulphur in Sulphur Maxx is present in the biologically available thiosulphate form and boots protein formation and nitrogen metabolism. Ammonium thiosulphate (ATS) is an excellent source of ammoniacal nitrogen that can be quickly absorbed by the plant due to its high solubility and nitrogen-sulphur content. Sulphur Maxx also contains Dimethyl Sulphone, a plant biostimulant specialising in improved nutrient uptake due to its ability to increase membrane permeability, to increase protein quantity and quality.
Sulphur Maxx can be applied to a range of crops including Cereals, OSR, Maize, Sunflower and Sugar beet. Soil sulphur is easily leached due to high spring rainfall making shallow-rooting plants particularly vulnerable to deficiency. Availability varies with soil and area and it is possible for any soil to be deficient. Soils of pH less than 5 or more than 8 have particularly limited sulphur availability.
Dimethyl Sulphone specialises in improved nutrient uptake due to its ability to increase membrane permeability, therefore adequate levels of sulphur can be maintained, improving overall plant health and productivity.
Cereals 2.5 - 5.0 l/ha: Winter wheat trials demonstrate the flexibility of Sulphur Maxx from BBCH32 to 55 in increasing yield, with later applications at BBCH55-9 being the most consistent timing for yield. Applications for protein content should be made at the late milky ripe stage (BBCH77) but avoiding flowering. OSR 5.0 - 10.0 l/ha: 1st application at stem extension. Avoid flowering. Maize 2.5 - 5.0 l/ha per application: 1st application at 4 - 6 leaf. Beet 5.0 l/ha per application: 4 - 6 leaf stage. Sunflower BBCH18 – 51.

Sulphur Maxx is a high-activity foliar sulphur formulation combining ammonium thiosulphate (ATS) with the biostimulant dimethyl sulphone. This unique co-formulation maximises sulphur availability and uptake, while also improving protein formation, nitrogen metabolism and overall plant productivity.
Sulphur is essential for protein and enzyme synthesis, chlorophyll production and the formation of essential oils and vitamins. It also improves nitrogen use efficiency and influences flavour in crops such as onions and garlic. Sulphur deficiency can lead to pale leaves which will in turn stunt growth and reduced the yield and quality of the crop.
Sulphur Maxx delivers sulphur in the biologically available thiosulphate form for rapid uptake, with dimethyl sulphone enhancing cell membrane permeability to further improve nutrient absorption. This combination ensures fast-acting results within 4 days, lasting for up to 30 days.
Sulphur Maxx can be applied to a wide range of crops, including but not limited to, cereals, oilseed rape, maize, sunflower and sugar beet. Shallow-rooting crops and those grown on light or high pH soils are particularly responsive to foliar sulphur applications.
Timing varies by crop:
Sulphur Maxx is designed to complement, not replace, basal sulphur applications. It is particularly valuable if soil-applied sulphur timings are missed or where in-season analysis shows a deficiency.
Sulphur uptake is rapid, with measurable increases in crop sulphur levels within 4 days of application. Its effects can last for around 30 days.
Dimethyl sulphone increases plant cell membrane permeability, allowing nutrients like sulphur to enter more easily. This leads to higher protein content and improved crop quality.
Sulphur Maxx is widely compatible but should not be tank-mixed with foliar phosphite products. Always check the IntraCrop compatibility list before mixing.
Typical rates are 2.5–5.0 l/ha depending on crop and growth stage, with 3.0 l/ha being standard. Apply in at least 100 l/ha water (150 l/ha preferable) for best coverage.
