Nicosulfuron 40g/L SC – Post-Emergence Corn Herbicide for Selective Grass & Broadleaf Control

Nicosulfuron 40g/L SC is a selective post-emergence sulfonylurea herbicide specifically engineered for controlling a wide spectrum of annual grass weeds and certain broadleaf weeds in corn fields.
The active ingredient, Nicosulfuron, is formulated as a suspension concentrate (SC), which ensures consistent performance under varying soil and weather conditions.

Physical & Chemical Characteristics

• Active Ingredient: Nicosulfuron at a precise concentration of 40g/L.

• Formulation Type: Suspension Concentrate (SC) for easy dilution and stable spraying.

• Mode of Uptake: Rapid foliar and root absorption with systemic translocation to growing points.

• Residual Activity: Provides residual control in the soil for up to several weeks, helping suppress new flushes of sensitive weeds.

Unlike some older herbicide forms, the SC formulation disperses quickly in the spray tank and stays uniformly suspended, minimizing the risk of nozzle blockage and uneven field coverage.

Performance & Versatility in the Field

Nicosulfuron 40g/L SC is absorbed mainly through leaves and stems, moving to the meristematic tissues where it disrupts essential enzyme activity, halting weed growth, and eventually causing plant death.
Typical symptoms include growth arrest, yellowing, and necrosis within days of application, with full weed control achieved in two to three weeks, depending on temperature and weed species.

This post-emergence herbicide performs best when weeds are young and actively growing, ideally before they exceed the 4-leaf stage.
It is particularly effective against problem grass species like barnyardgrass, foxtail, and wild millet, while also suppressing certain annual broadleaf weeds that may emerge alongside.

Key Advantages of the 40g/L SC Formulation

• Uniform Spray Quality: Stable emulsion reduces settling and ensures precise coverage.

• Consistent Weed Control: Reliable absorption and translocation under warm and cooler conditions.

• Safe Selectivity: When applied as directed, corn crops are well-protected while sensitive weeds are controlled.

• Convenient Handling: Liquid formulation simplifies measuring, mixing, and field application compared to powders or granules.

Whether you are working with precision ground sprayers or larger boom rigs for commercial-scale fields, Nicosulfuron 40g/L SC supports cost-effective, selective weed management that helps farmers secure clean rows and stronger yields.

Mode of Action

Nicosulfuron 40g/L SC works as a selective systemic sulfonylurea herbicide, primarily absorbed by the foliage and, to a lesser extent, by the roots of target weeds.
Once inside the plant, the active ingredient moves rapidly through the xylem and phloem, concentrating in the growing points (meristems) where cell division and growth are most active.

How It Works in the Weed

The core mechanism of Nicosulfuron involves inhibiting the enzyme acetolactate synthase (ALS), which is essential for the biosynthesis of the branched-chain amino acids valine, leucine, and isoleucine.
When this enzyme is blocked:

• The weed loses its ability to produce these vital amino acids.

• Cell division and new tissue formation stop.

• Affected weeds show gradual yellowing (chlorosis) and stunted growth.

• Complete weed death typically occurs within 20–25 days, depending on weed species and weather.

Why It’s Effective

Because Nicosulfuron is systemic, it not only kills the visible parts of the weed but also affects underground growing points.
This is critical for perennial grasses and deep-rooted weeds that might otherwise regrow after shallow contact treatments.

The 40g/L SC formulation ensures that the active ingredient spreads uniformly across the leaf surface and is quickly absorbed, even under cooler or fluctuating conditions.
This provides more consistent weed suppression compared to non-systemic contact herbicides.

Best Timing for Maximum Efficacy

Field trials and long-term use show that Nicosulfuron 40g/L SC works best when:

• Applied post-emergence, while weeds are young and actively growing (ideally before the 4-leaf stage).

• Soil moisture is adequate, supporting faster translocation within the weed.

• It is not used too late when weeds are mature and harder to suppress.

By targeting ALS enzyme pathways unique to plants, Nicosulfuron achieves highly selective weed control, protecting the corn crop while eliminating competitive weeds.
This mode of action makes it an integral part of modern corn weed management programs worldwide.

Target Weeds & Suitable Crops

Nicosulfuron 40g/L SC is specifically designed to deliver post-emergence selective control of problem weeds that reduce yield and compete aggressively with corn crops.
Thanks to its systemic ALS-inhibiting mode of action, it controls a broad range of both annual grass weeds and certain broadleaf weeds.

Common Grass Weeds Controlled

This product is widely recognized for its high efficacy against:

• Barnyardgrass (Echinochloa crus-galli)

• Foxtail species (Setaria spp.)

• Johnsongrass (seedling stage) (Sorghum halepense)

• Green foxtail and Yellow foxtail

• Wild millet and Crabgrass

Broadleaf Weeds Suppressed

When used at the recommended stage and dose, Nicosulfuron 40g/L SC also suppresses:

• Pigweed (Amaranthus spp.)

• Lambsquarters (Chenopodium album)

• Velvetleaf (Abutilon theophrasti)

• Cocklebur, Morning glory, and other small-seeded broadleaf weeds emerging alongside grasses.

Suitable Crops

• Primary Crop: Corn (Maize)

• Application Timing: Designed for post-emergence use in corn fields when the crop is well-established and weeds are in the 2–4 leaf stage.

• Selectivity: Excellent crop safety when applied as labeled; its systemic activity targets weeds while leaving the corn unharmed.

Regional Application

• Nicosulfuron is often tank-mixed with broadleaf herbicides such as 2,4-D, Dicamba, or Atrazine to broaden control to problem broadleaf weeds that might survive on Nicosulfuron alone.

Residual Partners:

• Some growers combine it with residual soil herbicides to extend the control window for later-emerging grasses and broadleaves.

Adjuvants:

• Always follow the nicosulfuron 40g/l sc label instructions when adding adjuvants or surfactants; non-ionic surfactants may be used if recommended to improve leaf coverage and uptake.

---

Important Mixing & Safety Precautions

Jar Test:
Always conduct a small jar test when combining Nicosulfuron 40g/L SC with other herbicides or fertilizers to confirm physical compatibility and avoid precipitation or layering in the tank.

Correct Mixing Order:

• Fill the tank at least halfway with clean water.

• Add Nicosulfuron SC slowly with agitation.

• Add compatible partners next, then any adjuvants.

• Continue to top up with water under constant agitation.

Weather & Drift:

• Apply under calm conditions to minimize spray drift to adjacent sensitive crops.

• Avoid spraying under extreme temperatures that could stress the crop and increase risk of phytotoxicity.

---

Resistance Management

Nicosulfuron is an ALS inhibitor (HRAC Group B), so it’s important to rotate with or tank-mix herbicides from different mode-of-action groups when possible.
This helps prevent or slow down the development of ALS-resistant weed populations, especially in corn fields with repeated use of sulfonylurea herbicides.

Use full labeled rates and proper timing—underdosing or late spraying increases the chance of resistance selection.

Integrate mechanical control, crop rotation, and other cultural practices alongside chemical treatments for best long-term results.

---

Equipment Cleaning

Always thoroughly rinse sprayers after using Nicosulfuron 40g/L SC, especially before switching to sensitive crops.
Use multiple clean water rinses and a recommended tank-cleaner if needed, to prevent herbicide residues from carrying over and harming subsequent fields.
