Whip Super Herbicide: Active Ingredient, Target Grasses, and Use

Whip Super is a selective post-emergence herbicide manufactured by Bayer containing Fenoxaprop-p-ethyl 9.3% EC. It provides targeted control of narrowleaf annual and perennial grassy weeds across broadleaf crops like soybean, cotton, blackgram, and groundnut.

Last reviewed: 10 November 2026

Active Chemistry and Grass-Specific Selectivity

Fenoxaprop-p-ethyl belongs to the aryloxyphenoxypropionate (FOP) chemical family (HRAC Group 1). It selectively inhibits the acetyl-CoA carboxylase (ACCase) enzyme in monocotyledonous grasses, preventing fatty acid biosynthesis in growing shoots while leaving dicot crops unaffected.

This enzymatic selectivity enables safe over-the-top application in broadleaf field crops without risk of phytotoxicity.

  • Target weeds: Echinochloa colona, Echinochloa crus-galli, Digitaria sanguinalis, Dactyloctenium aegyptium, and Eleusine indica.
  • Broadleaf safety: Safe for post-emergence application in soybean, cotton, groundnut, pulses, and onion.
  • Crop safener technology: Contains mefenpyr-diethyl as a safener to enhance crop tolerance in specific registered applications.

Optimal Timing and Spray Guidelines

Herbicide performance is highest when grassy weeds are actively growing with 2 to 4 leaves. Spraying during moisture stress or when weeds are mature reduces chemical uptake and translocation.

Uniform droplet distribution across weed leaves ensures rapid systemic entry into apical meristems.

  • Apply when adequate soil moisture is present following monsoon rains or scheduled irrigation.
  • Use knapsack or tractor sprayers equipped with flat fan or floodjet nozzles for uniform droplet deposition.
  • Avoid tank-mixing with broadleaf herbicides if antagonism is reported on the official label.

Common questions

What is the active ingredient in Whip Super?

Whip Super contains Fenoxaprop-p-ethyl 9.3% EC, an ACCase-inhibiting selective graminicide.

Can Whip Super be sprayed in standing soybean crops?

Yes, it is registered for selective post-emergence application in soybean to eradicate grassy weeds without harming the crop.

Does Whip Super control broadleaf weeds like bathua or parthenium?

No, Whip Super selectively targets only grassy (narrowleaf) monocot weeds; broadleaf weeds require alternative herbicides or manual weeding.
