Application Methods and Dosages
1. Seed Treatment

Dosage: 3-5 ml per kg of seeds

Method: Dissolve in required water quantity to form thin film

Timing: 20-30 minutes before sowing

Process: Apply solution, shade dry, then sow

2. Root/Tuber/Sett Treatment

Dosage: 3-5 ml per liter of water

Method: Dip roots/tubers in solution for 20-30 minutes

Application: Shade dry before transplanting

Benefits: Enhanced root establishment and early vigor

3. Foliar Spray

Dosage: 2-4 ml per liter of water

1st spray: Tillering/branching stage

2nd spray: Pre-flowering/late tillering stage

Rate: 250-500 ml per acre per spray
