Why EW Formulation is Better Than EC

This is the most important technical point farmers need to understand before choosing a pretilachlor product.

Feature EW (Emulsion in Water) – Rimove Plus EC (Emulsifiable Concentrate) Solvent base Water-based Petroleum/organic solvent-based Settlement time needed Only 12–18 hours of standing water 26–48 hours of standing water Layer formation speed Faster – forms protective soil layer quickly Slower – needs more time to bind Skin & eye safety Safer – no petroleum solvents More irritating Crop safety Higher – gentler on seedlings Risk of phytotoxicity if overdosed Odour Low / mild Strong petroleum smell Effectiveness in field More consistent, faster activation Depends on longer water retention ✅ Bottom line: EW formulation works faster, needs less water-holding time, and is safer for your paddy crop and yourself. Rimove Plus EW only needs 12–18 hours of standing water to set its protective layer — half the time needed by EC products.

When to Apply – Timing is Everything

Rimove Plus is a pre-emergence herbicide. It must be applied within 24–48 hours of sowing (direct seeded paddy) or within 2–4 days of transplanting.

⏰ Application Window: Apply 24 to 48 hours after sowing or transplanting. Missing this window reduces effectiveness dramatically — weeds that have already germinated underground will push through before the herbicide layer can stop them.

Field Conditions Required at Application

• Field should have standing water (2–3 cm)
• After spraying, maintain standing water for at least 12–18 hours (do NOT let the field dry out)
• Do not irrigate or drain for 3–4 days after application
• Apply when no rainfall is expected within 4–6 hours

How to Apply – Step by Step

1. Prepare your field: Level the field properly. Ensure 2–3 cm of standing water is present.
2. Timing: Apply within 24–48 hours after sowing OR 2–4 days after transplanting.
3. Mix: Measure the correct dose of Rimove Plus. Mix into a small amount of water first, then dilute in 150–200 litres of water per bigha.
4. Spray evenly: Use a knapsack sprayer with a flat fan nozzle for uniform coverage. Walk backwards to avoid disturbing the water.
5. Do not disturb water: Keep standing water in the field for minimum 12–18 hours after application (EW advantage). Do not irrigate or drain for 3–4 days.
6. Observe: Visible weed control results typically appear within 7–10 days.
