Jasmine (Jasminum sambac, Jasminum grandiflorum, Jasminum auriculatum and related species) is one of the most valuable fragrant flower crops, cultivated for loose flowers, garlands, perfumes, essential oil extraction, religious ceremonies and export markets. India is one of the world's largest producers of jasmine, with major cultivation in Tamil Nadu, Karnataka, Andhra Pradesh, Telangana, Maharashtra, Kerala, West Bengal and Odisha. High-quality jasmine production depends on healthy roots, vigorous branching, continuous flower bud formation, intense fragrance and effective disease and pest management. Integrating biofertilizers, biofungicides and biopesticides into jasmine cultivation improves soil fertility, enhances nutrient availability and naturally suppresses diseases and insect pests while promoting sustainable floriculture.

Beneficial microorganisms colonize the rhizosphere surrounding jasmine roots, improving soil biological activity, organic matter decomposition and nutrient cycling. Healthy root systems improve nutrient absorption, stimulate new shoot formation and support continuous flowering throughout the season.

Azotobacter fixes atmospheric nitrogen and supplies biologically available nitrogen for vigorous vegetative growth and lush green foliage. Phosphate Solubilizing Bacteria (PSB) convert insoluble phosphorus into plant-available forms, promoting stronger root systems, early flower bud initiation and increased flowering. Potassium Mobilizing Bacteria (KMB) improve potassium availability, enhancing flower size, fragrance, bud retention and shelf life. NPK Microbial Consortia provide balanced nutrient mobilization throughout the crop cycle, resulting in higher flower yield and improved bloom quality.

Micronutrient-solubilizing microorganisms further enhance crop performance. Zinc Solubilizing Bacteria improve chlorophyll synthesis, enzyme activation and photosynthesis. Sulphur Oxidizing Bacteria improve sulphur availability, which is essential for the synthesis of aromatic compounds responsible for jasmine fragrance. Mycorrhiza (AMF) improve phosphorus uptake, moisture absorption and drought tolerance. Silicon Solubilizing Bacteria strengthen stems, improve tolerance to heat stress and enhance overall plant vigour.

Jasmine is susceptible to several economically important diseases including Root Rot, Collar Rot, Wilt, Leaf Blight, Cercospora Leaf Spot, Rust, Powdery Mildew, Sooty Mold and Damping-off. These diseases reduce flowering, weaken plants and lower commercial flower production.

Beneficial microorganisms provide effective biological disease management. Trichoderma harzianum, Trichoderma viride and Trichoderma asperellum suppress soil-borne pathogens including Fusarium, Pythium, Rhizoctonia, Phytophthora and Sclerotium while stimulating vigorous root growth. Pseudomonas fluorescens functions as a plant growth-promoting rhizobacterium (PGPR), suppressing pathogens and inducing systemic resistance. Bacillus subtilis produces natural antimicrobial compounds that inhibit fungal and bacterial pathogens. Pseudomonas putida and Streptomyces lydicus improve rhizosphere biodiversity and provide long-term biological disease suppression.

Major insect pests include Bud Worm, Blossom Midge, Thrips, Aphids, Whiteflies, Mealybugs, Scale Insects, Spider Mites, White Grubs and Root-knot Nematodes. These pests damage flower buds, blooms and foliage, reducing flower yield and market quality.

Beauveria bassiana effectively controls bud worms, thrips, aphids and caterpillars. Lecanicillium lecanii provides biological control of aphids, whiteflies, mealybugs and scale insects. Bacillus thuringiensis var. kurstaki (BTK) effectively controls caterpillars and bud-feeding larvae. Metarhizium anisopliae suppresses white grubs and other soil-dwelling insect larvae. Purpureocillium lilacinum and Pochonia chlamydosporia effectively reduce root-knot nematode populations, protecting feeder roots and improving nutrient uptake.

Applying microbial products through pit application, soil drenching, drip irrigation, compost enrichment and periodic root-zone treatment establishes beneficial microbial populations throughout the plantation. Combined with pruning, irrigation and balanced nutrition, biological crop management significantly improves flower production, fragrance and plantation longevity.
