Overview

PREET PLUS is a selective pre-emergence herbicide from Tata Rallis, formulated with Pretilachlor 37% w/w EW.

It is designed to control weeds before they become established and compete with young paddy plants for water, nutrients, sunlight and growing space. The product is particularly useful for managing mixed weed populations containing grasses, sedges and broad-leaved weeds in transplanted rice.

Rallis introduced Preet Plus as part of its rice-focused herbicide portfolio.

Product Highlights

The published product specifications identify Preet Plus as Pretilachlor 37% EW for transplanted paddy and describe it as a selective broad-spectrum pre-emergence herbicide.

About the Product

Weeds emerging during the early stages of paddy cultivation can rapidly compete with rice plants for essential resources.

PREET PLUS is applied during the pre-emergence window to prevent susceptible weeds from establishing successfully.

Pretilachlor acts primarily on germinating weed seedlings, interfering with their normal growth and development. This provides the paddy crop with a cleaner establishment period and helps reduce early weed competition.

Recommended Crop

Transplanted Paddy / Rice

PREET PLUS is primarily recommended for transplanted paddy.

It is intended for application after transplanting and before significant weed emergence.

Target Weeds

Grassy Weeds

Commonly listed susceptible weeds include:

• Echinochloa crus-galli
• Echinochloa colona
• Leptochloa chinensis
• Panicum repens

Sedges

• Cyperus iria
• Cyperus difformis
• Fimbristylis miliacea

Broad-leaved Weeds

• Ludwigia parviflora
• Monochoria vaginalis
• Ammannia baccifera
• Sphenoclea zeylanica

The exact weed spectrum can vary with field conditions, weed population and application timing, so the current product label should be followed.

Application Guidelines

Application Method

PREET PLUS should be applied as a pre-emergence treatment in transplanted paddy.

For good performance, the field should have suitable soil moisture and a relatively uniform application across the treated area.

Recommended Dosage

Published Indian product listings give the following reference range for transplanted paddy:

500–600 ml/acre

with approximately:

150–200 litres of water/acre for spray application.

A commonly listed equivalent spray concentration is approximately:

2.5–3 ml/L of water

or approximately:

37–45 ml per 15-litre spray pump.

Always follow the current registered product label for the final dose and application method.

Best Application Stage

Pre-Emergence

Apply approximately 3–5 days after transplanting, before significant weed emergence, according to current product-use references.

The early application window is important because Pretilachlor is primarily intended to prevent susceptible weeds from establishing.

Field Conditions

For effective pre-emergence activity:

• Maintain adequate soil moisture.
• Ensure reasonably level field conditions.
• Maintain a shallow standing-water layer where specified by the label.
• Avoid excessive water movement immediately after application.
• Apply uniformly across the field.
• Avoid draining treated water into non-target areas.

Some current application guides recommend maintaining approximately 2–5 cm standing water during application and for several days afterward.

Mode of Action

Pretilachlor

Pretilachlor belongs to the chloroacetanilide herbicide group.

It acts mainly on germinating weed seedlings and interferes with processes required for normal cell division, cell elongation and early shoot/root development.

Application Procedure

Spray Method

1. Ensure the field has the recommended moisture/standing-water condition.
2. Fill the spray tank partially with clean water.
3. Measure the recommended quantity of PREET PLUS.
4. Add the product to the tank while mixing.
5. Add the remaining water.
6. Mix thoroughly.
7. Apply uniformly across the paddy field.
8. Maintain the recommended water condition after application.

Alternative Sand Application

Some product-use references describe mixing the recommended quantity with approximately 20–25 kg of dry sand per acre and broadcasting uniformly over standing water. Use this method only if it is permitted by the current product label.

Important Precautions

• Use only on the registered crop.
• Do not apply after weeds have become well established.
• Do not exceed the recommended dose.
• Avoid uneven application.
• Avoid excessive water flow immediately after treatment.
• Do not allow treated water to enter sensitive crops.
• Use a properly calibrated sprayer.
• Avoid spray drift.
• Follow the current manufacturer label.

Resistance Management

Repeated use of herbicides with the same mode of action can contribute to herbicide resistance.

For sustainable weed management:

• Use the recommended dose.
• Apply at the correct growth stage.
• Rotate herbicide modes of action where appropriate.
• Integrate mechanical and cultural weed-management practices.
• Avoid unnecessary repeated applications of the same active ingredient.

Storage Instructions

Storage
