Nichino Check Pretilachlor 50% EC Pre-Emergence Herbicide

• Verified formulation: Nichino confirms Pretilachlor 50% EC.
• Defined use: the registered crop system is transplanted rice, avoiding unsupported all-paddy claims.
• Pre-emergence positioning: it is intended for early use before the listed weeds become established.
• Specific weed spectrum: ten grasses, sedges and broadleaf weeds are named by Nichino and the Indian use table.
• Complete regulatory directions: hectare rate, water volume and PHI are available without inventing a per-litre or pump dose.

1. Early uptake: susceptible weeds take up Pretilachlor while germinating and during very early growth.
2. Group 15 action: the active ingredient inhibits very-long-chain fatty-acid production needed for normal growth in susceptible weeds.
3. Pre-emergence fit: it is positioned before weeds are established, so it is not a rescue treatment for uncontrolled mature weeds.

Repeated use of one herbicide group can select less-sensitive weed populations. Combine label-directed chemistry with crop rotation, clean seed, suitable land preparation and mechanical or hand weeding where practical.

DAT = days after transplanting; PHI = minimum pre-harvest interval. Do not convert these ranges into one universal ml-per-litre, pump or tank dose. Use the full label rate with the label water volume for the measured area.

• Use only in transplanted rice unless the current Check pack explicitly authorises another rice system.
• Apply as a pre-emergence treatment at the label timing; do not present Check as a treatment for established weeds.
• Measure the field area, calibrate equipment and distribute the label-directed spray-water volume uniformly.
• No sand, urea or fertiliser broadcast method is recommended here because it was not verified from a current Check label.
• Follow the physical pack for field-water depth, drainage and retention instructions; do not rely on generic figures from another Pretilachlor brand.
• Do not tank mix, layer or automatically sequence Check with a recommended product based on this page.
• If a later treatment is agronomically justified, diagnose the surviving weed species and select a separately applied, label-approved product with an appropriate different mode of action.

Read the current Check pack and leaflet before opening the container. Wear all label-required PPE, avoid skin, eye and inhalation exposure, keep the product locked away from children, food and animal feed, and prevent spray, runoff, washings and empty packaging from contaminating water. If exposure is suspected, seek medical attention promptly and show the label. The physical pack is the final authority for crop, weeds, dose, water, timing, application method, re-entry, PHI, PPE, first aid, storage and disposal.
