Dual Active Chemistry and Synergistic Mode of Action
Sprint combines two complementary modes of action: Carbendazim is a systemic benzimidazole (FRAC Group 1), which inhibits beta-tubulin polymerization during mitotic cell division. It is absorbed by germinating seeds and translocated acropetally to protect emerging sprouts.
Mancozeb is an inorganic dithiocarbamate complex (FRAC Group M03 - Multisite contact protectant), which denatures multiple sulfhydryl enzymes in fungal cells. This combination provides both therapeutic internal disinfection and a protective outer barrier.
- Systemic & Contact Synergy: Internal eradicative action paired with external broad-spectrum surface protection.
- Water Dispersible Slurry (WS): Specially engineered to adhere smoothly to seed coats and potato tuber skins without dusting off.
- Resistance Barrier: Multisite Mancozeb component prevents fungal strains from developing resistance to Carbendazim.
Target Pathogens in Potatoes and Field Crops
Sprint is officially registered under CIBRC standards as a seed dressing for potato, groundnut, and chili crops. In seed potato production, it provides control against black scurf (Rhizoctonia solani) and dry rot (Fusarium species).
In groundnut and pulses, it prevents collar rot (Aspergillus niger) and seed-borne root rot, ensuring uniform seedling emergence and dense plant populations.
- Potato Black Scurf: Eradicates seed-borne Rhizoctonia sclerotia on tuber surfaces before planting.
- Groundnut Collar Rot: Protects emerging cotyledons from destructive Aspergillus and Fusarium attacks.
- Nursery Damping-Off: Guards vegetable seeds against soil-borne Pythium and Rhizoctonia rots.
Application Guidelines and Slurry Dressing Protocol
Apply Sprint as a wet slurry treatment using specialized seed dressing drums or knapsack sprayers over moving tuber grading tables before planting or cold storage. Ensure uniform coating over tuber eyes without soaking cut surfaces excessively.
Allow treated potato seed tubers or field crop seeds to dry completely in shade before bagging or mechanical drilling. Never expose freshly treated seeds to direct hot sunlight.
- Slurry Dressing: Mix required quantity in clean water to prepare a smooth coating slurry.
- Shade Drying: Dry treated seeds under cool shade to set the protective fungicidal film.
- Personal Protection: Wear rubber gloves and dust masks during seed dressing operations.
