Check - Pretilachlor 50% EC - Nichino

Nichino Check Herbicide: Product Overview

Nichino Check is a selective pre-emergence herbicide containing Pretilachlor 50% EC. Its verified Indian use is early weed management in transplanted rice against specific grasses, sedges and broadleaf weeds.

Nichino recommends 400-600 ml per acre. The Government of India registered-use table expresses the rate as 1.0-1.5 litres per hectare in 500-700 litres of water per hectare and states a 75-90 day pre-harvest interval. An Odisha Government expert recommendation positions the formulation at 3-5 days after transplanting as a pre-emergence treatment.

Check is an HRAC/WSSA Group 15 herbicide. Use this mode-group information for stewardship, not as permission to use the product on an unlisted rice system, weed, timing or rate. The current physical Check pack and leaflet remain the final authority.

Why Choose Nichino Check?

• 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.

Technical Specifications

How Pretilachlor Works

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.

Verified Target Weeds in Transplanted Rice

Dose, Water, Timing and PHI

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.

Application and Stewardship Guidance

• 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.
