DESCRIPTION
Shriram Shaasak Sodium Acifluorfen 16.5% + Clodinafop Propargyl 8% EC Herbicide Details :
- Shriram Shaasak is a highly effective post-emergence herbicide used to control a wide range of broadleaf weeds and grassy weeds in crops. Its dual-active ingredients offer both contact and systemic action, giving farmers long-lasting weed control. It is especially effective in soybean, groundnut, and other broad-acre crops.
- Technical Content : Sodium Acifluorfen 16.5% + Clodinafop Propargyl 8% EC
- Mode Of Action : Sodium Acifluorfen acts by inhibiting the enzyme protoporphyrinogen oxidase (PPO), causing rapid membrane damage in susceptible plants, while Clodinafop Propargyl inhibits the ACCase enzyme, preventing lipid synthesis in grass weeds. This dual action ensures broad-spectrum weed control.
- Method & Time Of Application : Spraying
Features and Benefits:
- It is absorbed by the leaves and roots, translocated to the growing points of weed, it inhibits the enzyme acetyl CoA carboxylase (ACC-ase) and interferes with the production of fatty acids
- Gives early control of weeds hence no competition of weeds and Soybean crop results in better yields
- Has very good rain fastness: it is effective even if rains 2hrs after application
- Gives early control of weeds hence no competition of weeds and Soybean crop results in better yields
- Crops : Soybean, Groundnut Other broad-acre field crops
- Dosage : 1.0 - 1.2 liters per acre diluted in 300-400 liters of water as a post-emergent spray.
FAQs – Shriram Shaasak (Acifluorfen 16.5% + Clodinafop‑Propargyl 8% EC) Herbicide
1. What makes Shaasak an effective choice against both grasses and broadleaf weeds?
Ans. Shriram Shaasak combines a broadleaf herbicide (acifluorfen) with a grass-targeting systemic herbicide (clodinafop‑propargyl). Acifluorfen works as a fast-acting contact herbicide, while clodinafop moves within grasses to the growing points—together offering wide-spectrum coverage and synergistic weed control.
2. Which crops and weeds is Shaasak suitable for?
Ans. This herbicide is ideal for post-emergence use in soybean, groundnut, blackgram, and similar legumes. It effectively controls dominant weeds such as Echinochloa spp., Eleusine indica, Dactyloctenium aegyptium, Acalypha indica, and Euphorbia spp
3. When should Shaasak be applied for optimal effectiveness?
Ans. Use 400 mL per acre mixed in 150–200 L water, and apply when weeds have reached the 2–4 leaf stage, typically around 15–25 days after sowing or transplanting.
4. How effective is Shaasak in controlling weeds and improving yield?
Ans. Research trials show it significantly reduces weed density and dry weight, leading to higher yields. For instance, in groundnut, doses of 206.25 + 80 g/ha (active ingredients) delivered 1.44–1.65 t/ha pod yield—comparable or superior to hand weeding.
5. Is Shaasak safe for the target crop and subsequent crops?
Ans. Yes—when used as per label, it's generally non-phytotoxic to crops like groundnut and soybean, and safe for succeeding crops like finger millet.
6. Can Shaasak be mixed with other agrochemicals?
Ans. Yes—the product is compatible with many insecticides and fungicides. Always perform a jar compatibility test before tank mixing to avoid unexpected reactions.
7. Are there any safety or environmental precautions?
Ans. Use PPE (gloves, mask, goggles, protective clothing) during mixing and spraying. Avoid spraying near water bodies or during high wind, as it can harm aquatic organisms.
