Nicosulfuron 80% WDG is a highly selective post-emergence herbicide specifically designed to protect maize crops from unwanted competition. As a systemic herbicide, it is absorbed rapidly through the leaves, stems, and roots of target weeds, moving within the plant to disrupt vital growth processes. This action results in growth stagnation, chlorosis of stems and leaves, and the eventual death of sensitive weeds.
Your customers benefit from a water-dispersible granule (WDG) formulation, which ensures excellent solubility, easy handling, and even field coverage. This not only improves application efficiency but also reduces risks of clogs and sedimentation during spraying. With a shelf life of up to 2 years, Nicosulfuron 80% WDG stays stable in different storage and climate conditions, making it a dependable option for both temperate and tropical regions.
Because it’s a selective corn herbicide, Nicosulfuron provides reliable control of annual grasses like barnyardgrass and Setaria, as well as some broadleaf weeds such as pigweed, lambsquarters, and foxtail. When applied at the recommended growth stage — ideally before the fourth leaf stage — it delivers the best weed suppression while remaining gentle on the crop.
Manufactured to meet ISO and multiple country-specific quality standards, Nicosulfuron 80% WDG fits seamlessly into integrated weed management (IWM) strategies and gives you the flexibility to meet market demands with confidence.

Mode of Action
Nicosulfuron 80% WDG works as a systemic sulfonylurea herbicide, targeting the acetolactate synthase (ALS) enzyme in susceptible weeds. By inhibiting this key enzyme, the product effectively disrupts the synthesis of essential amino acids like valine, leucine, and isoleucine — all vital for cell division and plant growth.
When your customers apply Nicosulfuron, the active ingredient is absorbed rapidly through the leaves, stems, and roots, then translocated throughout the plant’s vascular system. This systemic action means that even underground parts of perennial weeds are affected, helping to stop regrowth at the source.
Visible symptoms start with the stagnation of new growth, followed by chlorosis and necrosis of leaves and stems. Most annual weeds will die within 20–25 days after application under normal temperature and moisture conditions. However, your customers should know that some perennial weeds might take longer to die, especially under low temperatures or stress conditions.
To achieve the best results, remind your growers to spray Nicosulfuron 80% WDG before the weed’s fourth leaf stage. This timing ensures maximum uptake and activity, helping maize crops stay ahead of weed competition during their critical growth phases.

By helping your buyers match Nicosulfuron 80% WDG to the right weed spectrum and growth stage, you give them a proven tool to protect maize yields and reduce costly weed competition throughout the season.
Recommended Dosage & Application
To help your customers get the best results with Nicosulfuron 80% WDG, it’s essential they follow the right dosage and timing. Clear instructions ensure effective weed control and minimize any risk of crop injury.
Your growers should always apply this herbicide post-emergence when target weeds are at their most vulnerable stage and the corn is within the safe leaf stage window.
Recommended Application Rates
| Crop | Target Weeds | Recommended Dosage (g/ha) | Application Method |
|---|---|---|---|
| Spring corn field | Annual grasses and broadleaf weeds | 49.5 – 75 | Post-emergence foliar spray |
| Summer corn field | Annual grasses and broadleaf weeds | 49.5 – 63 | Post-emergence foliar spray |
Application Tips
-
For best results, apply before the fourth leaf stage of the weeds. Weed control will be significantly reduced if applied after weeds grow too large.
-
Ensure good soil moisture and apply on warm days with temperatures around 20°C and air humidity above 60 percent.
-
Avoid application on corn under two leaves or beyond five leaves to reduce the risk of temporary chlorosis.
-
If rain occurs after six hours of spraying, there is generally no need for reapplication as absorption will be sufficient.
-
Nicosulfuron 80% WDG can be mixed with pyrethroid insecticides but should not be combined with organophosphate insecticides on the same crop.
By following these recommendations, you help your customers protect their maize crops more effectively while using this selective herbicide safely and responsibly.

Field Use Scenarios
When you show your customers real-world examples of Nicosulfuron 80% WDG in action, you help them understand exactly how to integrate this herbicide into their maize weed control programs with confidence.
Scenario 1: Spring Corn – Controlling Early Grasses
In spring maize fields, annual grasses like barnyardgrass and green foxtail can quickly compete with young corn for sunlight and nutrients. A grower applies Nicosulfuron 80% WDG at 49.5 to 75 grams per hectare right after the 2-leaf stage of the corn and before the weeds reach the fourth leaf stage.
Result: Early weed competition is eliminated, plants establish a strong stand, and the grower reduces the need for costly re-sprays later in the season.
Scenario 2: Summer Corn – Broadleaf Weed Pressure
In regions with summer maize planting, broadleaf weeds like redroot pigweed and lambsquarters often emerge alongside young corn. By applying Nicosulfuron 80% WDG at 49.5 to 63 grams per hectare during warm, humid conditions, the grower achieves effective systemic uptake and uniform control.
Result: Maize grows uniformly with minimal weed stress, helping farmers reach higher marketable yields at harvest.
Scenario 3: Tank Mixing with Pyrethroids for Integrated Control
A distributor provides guidance on tank mixing Nicosulfuron 80% WDG with a compatible pyrethroid insecticide in maize fields where both weed and insect pests are present. By combining products in a single pass, growers reduce fuel costs and field labor.
Result: Growers gain comprehensive protection against weeds and insect pests without compromising corn safety.
Scenario 4: Climate and Rain Considerations
A farmer in a temperate region applies Nicosulfuron 80% WDG on a warm day with air humidity above 60 percent and no forecast of heavy rain for 12 hours. Even if light rain occurs six hours after application, the systemic action ensures the herbicide has already been absorbed.
Result: Weed control remains consistent and the grower avoids wasting product or scheduling unnecessary repeat sprays.
These field scenarios demonstrate how you help your buyers get the best results from Nicosulfuron 80% WDG by providing practical, clear advice tailored to real growing conditions.
