Why Fenoxaprop-ethyl 98% TC Is a Go-To Herbicide for Grassy Weed Control
Introduction
Fenoxaprop-ethyl 98% TC (Technical Concentrate) is a powerful post-emergence herbicide known for its fast and selective control of grassy weeds in a wide range of broadleaf crops. With high purity and reliable performance, it is widely used in modern agriculture for efficient weed management.
Key Features
Selective control of grassy weeds
Safe for use in broadleaf crops (e.g., soybeans, cotton, vegetables)
Fast absorption and translocation within weed plants
⏱️ Quick visual effects (1–3 days after spraying)
Compatible with many herbicide tank mixes
Mode of Action
Fenoxaprop-ethyl is an ACCase (Acetyl-CoA Carboxylase) inhibitor. It blocks fatty acid synthesis in susceptible grass species, leading to growth inhibition, chlorosis, and death of the weed. The compound is rapidly absorbed by leaves and transported to growing points.
Target Weeds
| Weed Species | Type |
|---|---|
| Echinochloa crus-galli | Barnyardgrass |
| Setaria spp. | Foxtails |
| Digitaria spp. | Crabgrass |
| Lolium spp. | Ryegrass |
| Poa annua | Annual bluegrass |
Recommended Application
| Crop | Timing | Notes |
|---|---|---|
| Soybean | Post-emergence | Apply when grasses are 2–5 leaf stage |
| Cotton | Post-emergence | Avoid overlapping or overuse |
| Vegetables | Early post-emergence | Ensure target grasses are actively growing |
Advantages

FAQs
Q: Can Fenoxaprop-ethyl be used on cereals like wheat or rice?
A: No, it is phytotoxic to cereals; it is designed for broadleaf crop systems.
Q: Is a surfactant needed when applying Fenoxaprop-ethyl?
A: Yes, adding a non-ionic surfactant improves absorption and performance.
Q: How long before seeing visible weed control effects?
A: Usually within 2–3 days for chlorosis; complete control in 7–14 days.
Conclusion
Fenoxaprop-ethyl 98% TC stands out for its superior control of grassy weeds in broadleaf cropping systems. With high technical grade purity, rapid activity, and selective safety, it remains an essential herbicide in integrated weed management programs.
