Gengwei 55% SC | Mesotrione 5% + Atrazine 50% | Weed Control for Maize & Sugarcane

Gengwei 55SC – Mesotrione 5% + Atrazine 50% Herbicide for Maize & Sugarcane

Gengwei 55SC Herbicide by Technova Agri Solutions is a selective, dual-action herbicide formulated with Mesotrione 5% + Atrazine 50% SC for broad-spectrum weed management in Maize (Corn) and Sugarcane crops.

Its advanced Suspension Concentrate (SC) formulation combines two complementary herbicidal modes of action to control susceptible broadleaf weeds and annual grasses. With foliar activity and soil residual action, Gengwei 55SC helps reduce weed competition during critical stages of crop development.

Key Features & Benefits

• Dual-Action Formula: Combines Mesotrione 5% and Atrazine 50% for complementary herbicidal activity.
• Broad-Spectrum Weed Management: Targets various susceptible broadleaf weeds and annual grasses.
• Foliar & Residual Activity: Controls emerged weeds and helps suppress subsequent weed emergence under suitable conditions.
• Selective Herbicide: Intended for use in maize and sugarcane according to approved label instructions.
• Reduced Weed Competition: Helps crops utilize available water, nutrients and sunlight more effectively.
• Convenient SC Formulation: Liquid suspension concentrate designed for dilution and spray application.
• Two Modes of Action: HRAC Group 27 (HPPD inhibitor) and Group 5 (Photosystem II inhibitor).

Technical Specifications

How Gengwei 55SC Works

Gengwei 55SC combines two herbicidal active ingredients with different mechanisms of action to deliver complementary weed control performance.

1. Mesotrione 5% – HPPD Inhibitor

Mesotrione belongs to the Triketone chemical family and inhibits the enzyme 4-Hydroxyphenylpyruvate Dioxygenase (HPPD). This disrupts carotenoid biosynthesis, leaving susceptible weeds unable to protect their chlorophyll from sunlight damage.

Visible effects on susceptible weeds:

• Whitening or bleaching of leaves.
• Gradual loss of green pigmentation.
• Leaf tissue damage and necrosis.
• Progressive decline in weed growth.

2. Atrazine 50% – Photosystem II Inhibitor

Atrazine belongs to the Triazine herbicide family. It disrupts photosynthesis by binding to the D1 protein in Photosystem II. Atrazine can be absorbed through both roots and foliage of susceptible weeds.

Visible effects on susceptible weeds:

• Reduced photosynthetic activity.
• Leaf yellowing and chlorosis.
• Drying and deterioration of affected tissues.
• Growth suppression and eventual plant death.

3. Combined Herbicidal Performance

The combination of Mesotrione and Atrazine provides complementary weed control activity. Mesotrione disrupts pigment protection, while Atrazine inhibits photosynthesis and contributes additional soil residual activity.

Together, these active ingredients may improve control of certain susceptible weeds compared with either ingredient used alone, depending on weed species, application timing and environmental conditions.

Target Weeds Controlled or Suppressed

Gengwei 55SC is intended for management of susceptible weeds commonly found in maize and sugarcane cultivation.

Broadleaf Weeds

Grasses & Sedges

Note: Weed susceptibility varies with weed species, growth stage and field conditions. Difficult perennial weeds such as field bindweed and purple nutsedge may experience partial suppression rather than complete control. Refer to the registered product label for confirmed weed-control claims.

Recommended Dosage & Application Timing

The following application information is provisional and must be checked against the locally registered product label before use.

Suggested Water Volume: 100–120 liters per acre, subject to label instructions and sprayer calibration.

Application in Maize / Corn

• Apply only during the crop growth stages permitted on the product label.
• Prefer treatment of young, actively growing weeds, generally around the 2–4 leaf stage.
• Ensure even and uniform spray coverage.
• Use properly calibrated spraying equipment.
• Avoid application when the crop is under moisture, temperature or other environmental stress.
• Observe all restrictions on late-stage crop application.

Application in Sugarcane

• Apply during the approved early-season application window.
• Use directed or semi-directed spraying where required by the product label.
• Target actively growing susceptible weeds.
• Maintain uniform application without excessive overlapping.
• Avoid unnecessary contact with sensitive crop tissues.

Best Practices for Effective Weed Control

1. Target Young Weeds

Apply according to label directions when target weeds are young and actively growing. Large, mature or stressed weeds may be more difficult to control.

2. Maintain Suitable Soil Moisture

Adequate soil moisture can support the residual soil activity of Atrazine. Extremely dry soil may reduce performance against newly emerging weeds.

3. Select the Correct Spray Nozzle

Use a properly calibrated agricultural sprayer with label-recommended flat-fan or other suitable nozzles. Maintain appropriate spray pressure and droplet size to achieve uniform coverage while minimizing drift.

4. Avoid Unfavorable Weather

Avoid spraying during strong winds, extreme temperatures or other conditions likely to increase off-target drift, reduce herbicide performance or cause crop stress.

5. Follow Crop Safety Guidelines

Do not exceed the approved dosage or apply outside the permitted crop growth stages. Follow label restrictions relating to soil type, crop variety, crop rotation and nearby sensitive vegetation.

6. Practice Responsible Weed Resistance Management

Although Gengwei 55SC combines HRAC Groups 27 and 5, repeated use can contribute to herbicide resistance. Rotate effective modes of action and combine chemical weed control with appropriate cultural and mechanical practices.

Safety & Handling Precautions

• Always read and follow the registered product label before application.
• Wear appropriate protective clothing, chemical-resistant gloves and eye protection.
• Avoid inhaling spray mist and prevent direct skin or eye contact.
• Keep the product away from children, animals, food and drinking water.
• Avoid spraying near sensitive plants or non-target vegetation.
• Prevent contamination of ponds, irrigation canals and other water sources.
• Observe all label-required re-entry and crop rotation intervals.
• Store in its original, tightly sealed container in a secure, cool and dry location.
• Dispose of empty containers according to product-label and local regulatory instructions.
