Introduction
Super Valida is a biological fungicide based on Validamycin 10% SL — a natural product derived from fermentation of Streptomyces hygroscopicus. It is the leading solution for controlling sheath blight in rice across Nepal, prized for its effectiveness, safety to humans and the environment, and compatibility with integrated pest management programmes.
How It Works
Validamycin inhibits the enzyme trehalase in the fungal pathogen, disrupting carbohydrate metabolism and causing the fungus to starve. It does not kill the pathogen directly but prevents it from spreading, growing, and causing further damage. This mode of action has a very low risk of resistance development.
Key Benefits
- Highly effective against Rhizoctonia solani — the primary cause of rice sheath blight
- Biological origin — very safe for users, consumers, and the environment
- Low mammalian toxicity — ideal for integrated and organic-friendly programmes
- No residue concerns when used as directed
- Compatible with most other agrochemicals used in rice cultivation
