Mesotrione 5% + Atrazine 50% SC Herbicide

Selective Post-Emergence Weed Control Solution for Corn & Maize Fields

What Is Mesotrione 5% + Atrazine 50% SC?

Mesotrione 5% + Atrazine 50% SC is a modern selective suspension concentrate (SC) herbicide formulation specially designed for weed management in corn (maize) fields.

This combination herbicide contains two active ingredients:

• Mesotrione 5%
• Atrazine 50%

It combines two different herbicide modes of action to provide broader weed spectrum control, improved efficacy and longer-lasting protection compared with single active ingredient products.

Mesotrione belongs to the triketone herbicide group (HPPD inhibitor, HRAC Group 27). It blocks the production of carotenoid pigments in susceptible weeds, causing bleaching symptoms, disruption of photosynthesis and gradual plant death.

Atrazine belongs to the triazine herbicide group (Photosystem II inhibitor, HRAC Group 5). It interferes with photosynthesis by blocking electron transport in weed chloroplasts, resulting in growth inhibition and weed elimination.

The combination provides both contact activity and residual soil activity, helping control emerged weeds and suppress new weed flushes after application.

Target Weed Spectrum

Mesotrione 5% + Atrazine 50% SC provides effective control of many economically important weeds in corn production.

Annual Grass Weeds

Controls or suppresses:

• Barnyardgrass (Echinochloa crus-galli)
• Foxtail species (Setaria spp.)
• Crabgrass (Digitaria spp.)
• Goosegrass (Eleusine indica)

Broadleaf Weeds

Effective against:

• Pigweed (Amaranthus spp.)
• Lambsquarters (Chenopodium album)
• Morning glory (Ipomoea spp.)
• Velvetleaf (Abutilon theophrasti)
• Cocklebur (Xanthium spp.)
• Ragweed species

Other Difficult Weeds

• Smartweed
• Purslane
• Annual broadleaf weed complexes

Weed control performance depends on weed species, growth stage, soil conditions, weather and local application recommendations.

Application Scenarios & Crop Use

Corn / Maize Fields

Mesotrione 5% + Atrazine 50% SC is specially developed for selective weed control in corn production.

It is commonly used during:

✅ Early post-emergence weed control

• Corn seedling stage
• Early weed growth period
• Active weed development stage

✅ Field weed management

• Commercial corn farms
• Grain maize production areas
• Feed corn cultivation
• Large-scale agricultural fields

The formulation helps farmers maintain a clean field environment during the critical growth period when weeds compete strongly with corn for:

• Water
• Nutrients
• Sunlight
• Growing space

How Does Mesotrione + Atrazine Work?

Dual Mode of Action Advantage

The combination of Mesotrione and Atrazine provides complementary weed control:

1. Mesotrione Activity

• Rapidly absorbed through weed leaves and roots
• Causes white bleaching symptoms
• Stops chlorophyll development
• Reduces weed photosynthesis

2. Atrazine Activity

• Provides strong photosynthesis inhibition
• Controls many broadleaf weeds
• Provides residual soil activity

Together, they deliver:

✔ Faster weed suppression
✔ Wider weed spectrum
✔ Longer field protection
✔ Reduced weed competition with corn

Professional Application Guidance

1. Best Spraying Timing

For maximum effectiveness:

Apply when weeds are actively growing:

• Annual weeds: 2–6 leaf stage
• Broadleaf weeds: Early growth stage
• Corn: According to local registered label recommendations

Young weeds are generally easier to control and require lower application rates.

2. Weather Requirements

Recommended spraying conditions:

✔ Clear and calm weather
✔ Active weed growth
✔ Suitable soil moisture

Avoid application:

• Before heavy rainfall
• During drought stress
• During extreme heat
• Under cold stress conditions

3. Operation Tips

For better herbicide performance:

• Use clean water for spray preparation
• Maintain uniform spray coverage
• Avoid spray drift to sensitive crops
• Clean spraying equipment after use

Do not exceed recommended dosage rates.

All applications must follow local pesticide registration requirements.
