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%.
