Active Ingredients and Antibiotic Mode of Action
Plantomycin pairs streptomycin sulphate (9% w/w) with tetracycline hydrochloride (1% w/w) in a soluble powder (SP) formulation.
Both active substances are antibiotics that interfere with bacterial protein synthesis by binding to 30S ribosomal subunits, halting bacterial cellular multiplication and arresting vascular spread.
- Streptomycin Sulphate: Broad-spectrum aminoglycoside bactericide targeting bacterial cell walls and protein synthesis
- Tetracycline Hydrochloride: Suppresses bacterial elongation and provides synergistic suppression against resistant strains
- Systemic Penetration: Absorbed through foliage and roots, translocating through plant xylem to reach vascular infections
Target Bacterial Diseases across Indian Crops
Bacterial infections cause severe vascular wilts, water-soaked leaf spots, and bacterial oozing that fungicides cannot resolve.
Plantomycin is widely used in high-value horticulture and staples where bacterial outbreaks destroy harvest quality.
- Paddy (Rice): Bacterial leaf blight (BLB caused by Xanthomonas oryzae) and bacterial leaf streak
- Pomegranate: Bacterial blight or 'Telya' disease (Xanthomonas axonopodis pv. punicae) causing oily spots on fruit
- Citrus Orchards: Citrus canker (Xanthomonas citri) attacking leaves, twigs, and fruit rinds
- Tomato and Potato: Bacterial wilt (Ralstonia solanacearum) and black leg or soft rot (Erwinia carotovora)
Application Guidelines and Copper Synergy
Plantomycin is frequently tank-mixed with copper oxychloride (COC) to establish a dual bactericidal and fungicidal barrier.
Dissolve Plantomycin completely in clean water, ensuring protective spraying occurs before systemic bacterial collapse destroys plant vascular vessels.
- Foliar Dilution: Standard recommendation is 0.5 to 1 gram per liter of water (approx. 50 to 100 grams per acre in 100 to 200 liters)
- Copper Combination: Mixing with copper oxychloride (at 2 to 2.5 g per liter) provides synergistic broad-spectrum control
- Preventive Action: Spray immediately after hail damage, pruning, or monsoon storms that create mechanical entry wounds

Common questions
What is the technical composition of Plantomycin?
Plantomycin contains streptomycin sulphate 9% plus tetracycline hydrochloride 1% SP, manufactured by Aries Agro.
Can Plantomycin be mixed with Copper Oxychloride (COC)?
Yes, combining Plantomycin with copper oxychloride is a widely recommended field practice that enhances bactericidal performance.
Does Plantomycin control fungal diseases like powdery mildew?
No, Plantomycin is an antibacterial formulation specific to plant pathogenic bacteria; it does not control true fungal diseases.
