Abstract: The present invention relates to a solid bio-pesticidal composition comprising of elemental Sulphur in the range of 60% w/w to 99% w/w, Azadirachtin in the range of 0.01% w/w to 20% w/w and at least one agrochemically acceptable excipient wherein particles of the composition is in the range of 0.1 micron to 60 microns, wherein the composition is in the form of water dispersible granules, broadcast granules, extruded granules, spheronised granules and powders. The invention relates to a process of preparing and also to a method for treatment of plant, crop, locus or soil against pests or diseases or managing pesticidal resistance or reducing pesticidal residue by application of a solid bio pesticidal composition. The invention also relates to a method for controlling pests and diseases by applying a solid bio pesticidal composition by foliar means at a dosage of 0.5 kg/ha to 30 kg/ha to a plant or a crop or parts thereof.

Abstract: The invention relates to a water dispersible granular composition comprising of 0.1% to 70% by weight of manganese salts, complexes, derivatives or mixtures thereof, 1% to 90% by weight of elemental sulphur and 1% to 30% by weight of dispersing agent, with granules in a size range of 0.1-2.5 mm and comprising particles in the range of 0.1-20 microns. The invention further relates to liquid suspension composition comprising 0.1% to 55% by weight of manganese salts, complexes, derivatives or mixtures thereof, 1% to 60% by weight of elemental sulphur, at least one structuring agent and at least one surfactant, where the composition has particle size range of 0.1-20 microns. The invention further relates to a process of preparing the crop nutrition and fortification composition and to a method of treating the plants, seeds, crops, plant propagation material, locus, parts thereof or the soil with the composition.
