PRODUCT : Containing strain of Thiobacillus thioxidans.


ACTIVE INGREDIENT : Cell mass of Thiobacillus thioxidans. Cell Count: 1X109 /ml. min. or 1X109 /gm. min.

FORMULATION : AS (Aqueous Suspension) and GR (Granules)

SPECTRUM : Sulphur is a macronutrient required by plants for synthesis of enzymes, oils, chlorophyll and vitamins. In legumes, sulphur is necessary for the efficient nitrogen fixation. Sulphur is not mobile in the plant, continuous supply of sulphur is needed from emergence of plant to crop maturity. A deficiency of sulphur at any stage of growth can result in reduced yields. Crops which require sulphur are Spring Wheat, Barley, Oat, Rye, Canola, Flax, Pea, Lentil, Potato, Mustard, Alfalfa etc.

MODE OF ACTION : The dormant form of Thiobacillus thioxidans cells on reaching the soil gets activated and produces fresh batch of active cells which secretes enzymes like thioredoxins and number of organic acids - Sulphuric acid, Carbonic acid. These organic acids solubilise large amount of Sulphur, Zinc and other essentials elements which are present in the soil in elementary or complex form.

SEED TREATMENT : Mix 5-10 ml. of Biosulf/Sulf-cure with sufficient quantity of water and treat 1 kg of seeds. Shade dry them for half an hour before sowing.

SEEDLING DIPPING : Mix 50-100 ml. of Biosulf/Sulf-Cure in 10-20 ltrs. of water and dip the seedling roots for 30 minutes before transplanting.

SETT TREATMENT : Mix 250-500 ml. of Biosulf/Sulf-Cure in 100 ltrs. of water and dip the setts required for 1 acre for 30 minutes before planting in the field.

SOIL APPLICATION : Mix 750-1000 ml. or 2-4 kg. of Biosulf/Sulf-Cure with 30-40 kg’s of Farm Yard Manure (FYM). In absence of FYM, soil of the field can be used. After thoroughly blending broadcast in 1 acre of land before last ploughing or after first irrigation or irrigate the field after its application. In standing crop, give light irrigation after its application.

TREE TREATMENT : Apply 0.75-1.0 ltrs. Biosulf/Sulf-Cure at active root zone directly early in the season for most of the field trees, fruit trees and ornamental trees through drip irrigation. For Vines apply 0.75-1.5 ltrs. of Biosulf/Self-Cure mixed in 100-150 ltrs. of water per acre or 100 gm of Biosulf/Sulfcure per tree at active root zone or 25-50 ml Bio-Sulf per tree at active root zone.
