Application and dosing
The dose depends on the purpose: in-season treatments, seed treatment or tuber treatment. Each of the six crops on the registered label has a full season program: timing, dose per treatment, season total and the number of hectares per 20 l canister.
Season program — foliar spray

Applications requiring a specific concentration
| Application | Concentration / dose | Notes |
|---|---|---|
| Seed treatment | 0.3 l / 1000 kg of seeds | Soak for 6–12 hours or mechanical treatment |
| Tuber treatment (potato) | 300–400 ml / 1000 kg of tubers | Before planting |
| Microgreens | 1–2 l / 1000 l of water (0.1–0.2%) | Spray seeds and sprouts, repeat every 48 hours |
Dose calculated per mass of seed and seed tubers or per volume of water: the water volume follows from the technology (seed treatment equipment, tank), not from the field area.
The product can be mixed with many plant protection products — the user is responsible for testing the mixture before use. Add ProtoHumiX® to the tank last.
