Premier Dhanuka Herbicides and Chemical Actives

Dhanuka Agritech partners with leading global chemical innovators to bring advanced selective weed control solutions to Indian agriculture.

Understanding active ingredients and application timing ensures maximum weed control without risking crop phytotoxicity.

  • Sempra (Halosulfuron Methyl 75% WG): World-renowned selective specialist for purple nutsedge (Cyperus rotundus / Motha) in sugarcane and maize
  • Targa Super (Quizalofop Ethyl 5% EC): Selective post-emergence graminicide eliminating grassy weeds in soybean, cotton, and groundnut
  • Craze (Pretilachlor 50% EC): Selective pre-emergence herbicide controlling grasses, sedges, and broadleaf weeds in transplanted rice
  • Barrier (Oxyfluorfen 23.5% EC): Pre-emergence and early post-emergence contact herbicide for onion, tea, and potato crops
  • Chempa (Pyrazosulfuron Ethyl 10% WP): Broad-spectrum early post-emergence herbicide for direct-seeded and nursery rice

Target Weeds and Approved Cropping Systems

Dhanuka herbicides are registered across rice, wheat, soybean, cotton, sugarcane, and horticultural crops.

Applying at recommended crop vegetative stages ensures thorough weed eradication while conserving soil moisture and nutrients.

  • Nutsedge management: Sempra translocates systemically into underground tubers, killing the reproductive source of Cyperus rotundus
  • Soybean & pulses: Targa Super selectively kills Echinochloa, Digitaria, and wild grasses without harming broadleaf crops
  • Paddy weed control: Craze and Chempa provide clean, weed-free baselines for healthy tiller establishment

Spraying Instructions, Moisture, and Operator Safety

Apply using a well-calibrated knapsack sprayer equipped with flat fan or floodjet nozzles for uniform chemical deposition.

Optimal herbicidal uptake requires adequate soil moisture at the time of application, as moisture-stressed weeds develop thick cuticular waxes.

Wear standard personal protective equipment during chemical handling and spraying.

  • Nozzle type: Flat fan nozzles deliver uniform coarse droplets that minimize drift onto neighboring crops
  • Soil moisture: Apply when fields have good moisture to maintain active weed metabolism and uptake
  • Personal protection: Wear chemical-resistant gloves, protective clothing, and eye goggles during preparation

Common questions

What weed does Dhanuka Sempra specifically control?

Dhanuka Sempra is specifically formulated to control purple nutsedge (Cyperus rotundus), commonly known as Motha or Lavala.

Can Dhanuka Targa Super be sprayed over soybean crops?

Yes, Targa Super is highly selective to broadleaf crops; it kills grassy weeds without causing any injury to soybean or cotton.

Why is soil moisture essential when spraying post-emergence weedkillers?

Adequate soil moisture ensures weeds are actively transpiring and metabolizing, facilitating rapid systemic chemical absorption and downward translocation.
