Anthurium (Anthurium andraeanum and related hybrids) is one of the most valuable tropical ornamental flower crops, cultivated for its attractive coloured spathes, glossy foliage and long-lasting cut flowers. It is widely grown under shade houses, polyhouses and greenhouse conditions for domestic and export markets. In India, commercial anthurium cultivation is concentrated in Kerala, Karnataka, Tamil Nadu, Maharashtra, Sikkim, West Bengal, Meghalaya and Arunachal Pradesh. Successful anthurium production depends on healthy roots, vigorous vegetative growth, continuous flower production, vibrant spathe colour and effective disease and pest management. Integrating biofertilizers, biofungicides and biopesticides into anthurium cultivation enhances nutrient availability, improves root health and naturally suppresses diseases and insect pests while promoting sustainable floriculture.

Beneficial microorganisms colonize the rhizosphere surrounding anthurium roots, improving biological activity in the growing media, accelerating organic matter decomposition and enhancing nutrient cycling. Healthy microbial populations promote vigorous root establishment, stronger plant growth and continuous flowering throughout the year.

Azotobacter fixes atmospheric nitrogen and supplies biologically available nitrogen for lush green foliage and vigorous vegetative growth. Phosphate Solubilizing Bacteria (PSB) convert insoluble phosphorus into plant-available forms, promoting strong root systems, healthy crown development and early flower initiation. Potassium Mobilizing Bacteria (KMB) improve potassium availability, enhancing spathe size, flower colour, stem strength and vase life. NPK Microbial Consortia provide balanced nutrient mobilization throughout the crop cycle, resulting in continuous flowering and premium flower quality.

Micronutrient-solubilizing microorganisms further improve crop performance. Zinc Solubilizing Bacteria improve chlorophyll synthesis, enzyme activation and photosynthetic efficiency. Sulphur Oxidizing Bacteria enhance sulphur availability for healthy plant metabolism and flower development. Mycorrhiza (AMF) improve phosphorus uptake, water-use efficiency and tolerance to environmental stress. Silicon Solubilizing Bacteria strengthen plant tissues, improve leaf quality and enhance resistance to heat and moisture stress.

Anthurium is susceptible to several economically important diseases including Bacterial Blight, Root Rot, Stem Rot, Anthracnose, Leaf Spot, Fusarium Wilt, Phytophthora Rot and Damping-off. These diseases reduce flower production, damage foliage and significantly lower commercial quality.

Beneficial microorganisms provide effective biological disease management. Trichoderma harzianum, Trichoderma viride and Trichoderma asperellum suppress soil- and media-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 effective against fungal and bacterial pathogens. Pseudomonas putida and Streptomyces lydicus improve microbial diversity in the root zone and provide long-term biological disease suppression.

Major insect pests include Thrips, Aphids, Mealybugs, Scale Insects, Whiteflies, Spider Mites, Fungus Gnats and Root-knot Nematodes. These pests damage leaves, flower stalks and spathes, reducing marketable flower quality.

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

Microbial products applied through potting media treatment, root dipping, drip irrigation, compost enrichment and periodic root-zone drenching establish beneficial microbial populations throughout the growing media. Combined with proper humidity management, irrigation and balanced nutrition, biological crop management significantly improves flower quality, foliage appearance and plant longevity.
