Active Antibiotic Ingredients and Mode of Action
Plantomycin combines two complementary aminoglycoside and tetracycline antibiotics formulated specifically for agricultural crop protection. Streptomycin Sulphate (9%) binds irreversibly to the 30S ribosomal subunit in bacterial cells, causing misreading of genetic codes and inhibiting protein synthesis.
Tetracycline Hydrochloride (1%) prevents the attachment of aminoacyl-tRNA to the ribosomal acceptor site, effectively shutting down bacterial protein elongation. This dual-action systemic bactericide penetrates plant vascular tissues rapidly, arresting bacterial cell division and systemic colonization.
- Active Ingredients: Streptomycin Sulphate 9% + Tetracycline Hydrochloride 1% SP.
- Dual Antibiotic Synergy: Inhibits bacterial 30S ribosomal protein synthesis via two distinct biochemical pathways.
- Systemic Translocation: Absorbs through leaf stomata and moves systemically inside xylem vessels.
- Broad Antibacterial Spectrum: Controls both Gram-negative and Gram-positive phytopathogenic bacteria.
Target Crops and Bacterial Disease Spectrum
In rice cultivation, Plantomycin is widely utilized to control Bacterial Leaf Blight (BLB caused by Xanthomonas oryzae), halting water-soaked lesions that turn straw-colored and scorch productive leaf canopies.
In horticulture, it treats Citrus Canker (Xanthomonas citri), Black Rot in cabbage and cauliflower (Xanthomonas campestris), Bacterial Wilt in solanaceous vegetables (Ralstonia solanacearum), and Fire Blight in apples, preventing vascular collapse and fruit blemishes.
- Bacterial Leaf Blight (Rice): Arrests translucent water-soaked streaks and marginal leaf drying.
- Citrus Canker: Controls crater-like raised corky lesions on citrus leaves, twigs, and fruit rinds.
- Black Rot (Cole Crops): Suppresses V-shaped yellow necrotic lesions on cabbage and cauliflower leaf margins.
- Bacterial Wilt and Canker: Applied as foliar spray or root drench to halt systemic bacterial wilt progression.
Application Protocol, Tank Mixing and Safety
To optimize antibacterial efficacy, Plantomycin is frequently tank-mixed with copper-based protectants such as Copper Oxychloride 50% WP. Copper provides a broad surface barrier, while Plantomycin enters vascular systems to arrest internal bacterial multiplication.
Apply at the earliest appearance of bacterial symptoms or prophylactically after stormy weather with strong winds that cause leaf lacerations. Adhere strictly to CIBRC regulations regarding approved crops and observe label pre-harvest intervals.
- Copper Tank-Mix Synergy: Combine with Copper Oxychloride for dual-action surface and vascular protection.
- Prophylactic Timing: Apply immediately following high-wind or hail events that create microscopic leaf wounds.
- Water Solubility: Soluble powder dissolves cleanly in water for unhindered knapsack or power spraying.
- Safety Precautions: Wear personal protective equipment and avoid repeated unapproved antibiotic applications.

Common questions
What is the active chemical composition of Plantomycin?
Plantomycin contains Streptomycin Sulphate 9% and Tetracycline Hydrochloride 1% SP, a systemic agricultural antibiotic formulation.
Why is Plantomycin often mixed with Copper Oxychloride?
Mixing Plantomycin with Copper Oxychloride provides synergistic disease control: copper protects the outer plant surface while Plantomycin moves systemically inside plant vascular tissues to kill bacteria.
Which major rice disease is controlled by Plantomycin?
Plantomycin is extensively used to control Bacterial Leaf Blight (BLB) caused by Xanthomonas oryzae in rice crops.
Where can farmers verify official label guidelines for Plantomycin?
Farmers should consult the approved package leaflet or check official registrations on the Central Insecticides Board and Registration Committee (CIBRC) website.
