Product Overview

Adama Galigan Herbicide (Oxyfluorfen 23.5% EC) is a broad-spectrum, selective herbicide that provides excellent control of annual broadleaf and grassy weeds in various crops. It works both as a pre-emergence and early post-emergence herbicide, forming a protective barrier on the soil surface that prevents weed seed germination and growth.

Mode of Action

Oxyfluorfen belongs to the diphenyl ether group of herbicides. It works by inhibiting the protoporphyrinogen oxidase (PPO) enzyme in plants, which disrupts chlorophyll formation and causes cell membrane destruction.

When weeds emerge through the treated soil or are directly contacted by the spray, they turn brown and dry out within a few days.

Key Benefits

✅ Dual action – Effective as both pre- and early post-emergence herbicide
✅ Broad-spectrum control – Works on both broadleaf and grassy weeds
✅ Long-lasting residual effect – Keeps fields weed-free for weeks
✅ Crop selectivity – Safe on recommended crops when applied at the right stage
✅ Reduces manual weeding costs
✅ Does not affect soil fertility or next crop

Target Weeds Controlled

• Broadleaf Weeds: Amaranthus spp., Chenopodium album, Digera arvensis, Trianthema portulacastrum, Parthenium hysterophorus

• Grassy Weeds: Echinochloa spp., Dactyloctenium aegyptium, Eleusine indica

• Sedges: Cyperus spp.

Recommended Crops and Uses

Use 200–300 liters of water per acre for uniform coverage.

Application Guidelines

• Apply immediately after sowing or transplanting but before weed emergence.

• Ensure soil is moist for best results.

• Avoid disturbing the soil surface after application to maintain the protective barrier.

• Use flat fan nozzles for even spray distribution.

• In case of early post-emergence, ensure weeds are at the 2–3 leaf stage.

Safety Precautions
