Validamycin 3% L:
Validamycin 3% L is a systemic antibiotic fungicide formulated as a liquid. Produced through fermentation, it is highly specific and effective against soil-borne diseases caused by Rhizoctonia fungi. It is widely regarded as the most reliable solution for controlling Sheath Blight in Rice. Being an antibiotic fungicide, it has a low toxicity profile for mammals and is environmentally safer than many synthetic alternatives. It acts on the fungal hyphae, stopping the infection without damaging the plant.
Mode of Action:
Validamycin 3% L functions as a fungistatic agent (stops fungal growth) rather than a fungicidal agent (killing immediately).
Enzyme Inhibition: It specifically inhibits the enzyme trehalase within the fungal cells.
Energy Starvation: The fungus requires trehalase to digest trehalose (a carbohydrate) for energy. By blocking this enzyme, Validamycin effectively starves the fungus of energy.
Hyphal Disruption: It causes abnormal branching at the tips of the fungal hyphae, preventing the fungus from spreading and penetrating further into the plant tissue.
Primary Uses and Target Crops:
This fungicide is primarily used in Rice cultivation but is also effective in potatoes and vegetables.
Key target crops include:
Cereals: Rice (Paddy)
Tubers: Potato
Vegetables: Tomato, Cabbage, Cauliflower, Ginger
Others: Tea, Coffee
Application and Dosage:
Validamycin 3% L is mixed with water and applied as a foliar spray. Thorough coverage of the lower parts of the plant (sheaths) is crucial for rice.
The recommended dosage varies by crop:
Rice (Paddy): To control Sheath Blight (Rhizoctonia solani), use 400 to 500 ml per acre.
Timing: Apply at the first appearance of sheath blight symptoms or during the tillering to booting stage.
Potato: For Black Scurf, use 2.5 ml per liter of water as a spray or seed treatment.
Vegetables: For Damping Off and Root Rot, use 400 to 500 ml per acre.
General Mixing Rate: A common mixing rate is 2 ml to 2.5 ml per liter of water.
Target Diseases:
This fungicide is highly specialized for Rhizoctonia species.
Commonly controlled diseases include:
Sheath Blight (Rice - Major target)
Black Scurf (Potato)
Damping Off (Vegetable seedlings)
Root Rot
Web Blight
Safety Precautions:
Strict adherence to safety precautions is essential. As an antibiotic, it requires careful handling.
Key safety recommendations include:
Personal Protective Equipment (PPE): Wear protective clothing, rubber gloves, boots, and a face mask/goggles during mixing and spraying.
Avoid Contact: Avoid inhalation of spray mist and contact with skin and eyes. Wash splashes immediately with soap and water.
Handling Practices: Do not eat, drink, or smoke when using the product. Wash hands and exposed skin thoroughly with soap and water after use.
Environmental Safety: While it has low toxicity to fish, do not contaminate water bodies or clean equipment near streams or ponds.
Storage:
Store the product in its original container in a cool, dry, and well-ventilated place, away from direct sunlight, moisture, food, and animal feed. Keep out of reach of children and uninformed persons.
