Oxadifen-ethyl (CAS 163520-33-0): Product Overview
Oxadifen-ethyl (CAS 163520-33-0) is a selective herbicide safener widely used in agriculture to protect crops from herbicide-induced damage. It enhances the tolerance of crops like corn, soybeans, and cereals to specific herbicides, enabling effective weed control without harming the cultivated plants.

Detailed Applications of Oxadifen-ethyl
Primary Uses
- Herbicide Protection: Applied as a seed treatment or foliar spray to mitigate damage from herbicides like fenoxaprop-P-ethyl.
- Crop Safety: Activates glutathione S-transferase (GST) in crops, accelerating herbicide detoxification.
- Synergistic Formulations: Often combined with post-emergence herbicides for integrated weed management.
Recommended Crops & Herbicides
| Crop | Compatible Herbicides | Application Rate |
|---|---|---|
| Corn | Fenoxaprop-P-ethyl, Isoxaflutole | 50–100 g/ha |
| Soybean | Quizalofop-P-ethyl | 30–60 g/ha |
| Wheat | Clodinafop-propargyl | 40–80 g/ha |
Usage Guidelines
Application Methods
- Seed Treatment: Mix 1–2 g/kg of seeds before sowing.
- Foliar Spray: Dilute 50–100 g/ha in 200–300 L water; apply during early crop growth stages.
Precautions
- Avoid application under extreme temperatures (>35°C or <10°C).
- Do not mix with alkaline substances.
Case Studies
Case 1: Corn Field Protection in Iowa, USA
Problem: Herbicide (fenoxaprop-P-ethyl) caused chlorosis in hybrid corn.
Solution: Seeds treated with Oxadifen-ethyl (1.5 g/kg).
Result: 92% reduction in crop injury; yield increased by 18%.
Case 2: Soybean Farm in Paraná, Brazil
Problem: Quizalofop-P-ethyl damaged soybean seedlings.
Solution: Foliar spray of Oxadifen-ethyl (60 g/ha) at 2-leaf stage.
Result: 100% crop survival; weed control efficiency reached 95%.
