Bayer Curbix® Pro Insecticide — A Reliable Hopper-Control Solution for Paddy

Introduction of Bayer Curbix® Pro Insecticide

Bayer’s Curbix® Pro is a modern, dual-action insecticide developed to protect rice (paddy) crops from hopper attacks, especially the damaging Brown Plant Hopper (BPH) and White‑Backed Plant Hopper (WBPH). For paddy farmers seeking effective, safe, and economical pest-control solutions — particularly important in high-yield crops — Curbix Pro is a promising option.

Technical Name and Composition

• Active ingredients / technical name: Ethiprole 10.7% + Pymetrozine 40% w/w WG (Water-Dispersible Granules)
  
• Formulation: Water-dispersible granule (WDG) — dissolves quickly in water to form a uniform spray solution, helping in even distribution and effective absorption by the crop.
  

This dual-ingredient combination brings together two distinct modes of action, increasing overall effectiveness and reducing chances of resistance development among hopper populations. 

Recommended Dose and Application (Per Acre / Per Hectare / Per Litre)

As per the manufacturer’s (Bayer) recommendations for paddy:

• Dose per hectare: 375–425 g of Curbix Pro WDG per hectare, diluted in about 375 litres of water. 
• Translating this to per acre: 1 hectare ≈ 2.471 acres. So, roughly ≈ 150–172 g/acre (375–425 g ÷ 2.471). Many dealer sites or product-sell listings cite around 170 g / acre as the typical label dose.
  
• Water dilution: As recommended, about 375 litres of water per hectare. So for one acre, dilution roughly proportionate (≈ 150–180 litres water, depending on spray equipment and coverage requirement).
  

Note: Some non-official vendor pages mention “115 ml/acre” — but that seems inconsistent with official manufacturer recommendation; it may refer to another crop or dosage guideline from other sources — always follow label instructions provided with the product.

Uses and Target Pests

Curbix Pro is specifically recommended for rice (paddy) crops. Its primary targets are:

• Brown Plant Hopper (BPH)
  
• White-Backed Plant Hopper (WBPH)
  

These hoppers are notorious for sucking sap from rice plants, weakening them, causing “hopper burn,” reducing tillering and yield — a major threat to rice yield in many parts of India. 

Curbix Pro is therefore used at the first sign of hopper infestation. This early intervention helps prevent hopper build-up and protects crop health.

Important: As per the label and official brochures — Curbix Pro should only be used on paddy. It is not recommended (and often disallowed) for other crops. 

Mode of Action & How It Works

• Curbix Pro works via a dual mode of action: the two active ingredients — Ethiprole and Pymetrozine — affect the insect nervous system in different ways. Ethiprole disrupts GABA-gated chloride channels, while Pymetrozine affects sensory channel (chordotonal organ TRPV) functioning. This combo leads to paralysis of the insects and eventually their death.
  
• The formulation (WDG) ensures translaminar action — meaning it penetrates and moves within leaf tissues, giving more thorough coverage, better absorption and lasting effect.
  
• This results in immediate cessation of feeding, paralysis, and control of hopper populations.
  

Because of the dual-action and different modes of action, Curbix Pro is also suitable for resistance management — it helps reduce the chances of hoppers developing resistance to insecticides.

Benefits of Using Curbix® Pro

Using Curbix Pro offers several advantages for rice farmers:

Effective hopper control: Especially against BPH and WBPH, reducing infestation quickly, stopping sap-sucking damage.

Resistance management: Dual active ingredients and dual modes of action help avoid cross-resistance to other hopper control products — a big plus when pests become resistant over time.

Crop safety and better uptake: WDG formulation dissolves uniformly and is plant-safe, with better spread and absorption — leading to more thorough pest control.

Prevents hopper burn, ensures healthy crop: By controlling hoppers, it helps avoid hopper burn, ensures greener crop canopy, better grain filling and potentially higher yields.

Cost-effective for rice cultivation: Compared to repeated use of less-effective insecticides or losses due to hopper damage, a timely application of Curbix Pro can safeguard yield — making it economically beneficial for farmers.

Practical Recommendations & Precautions

• When to spray: As soon as hopper infestation is visible — ideally before hopper numbers build up. Early spraying helps prevent major damage.
  
• Spray coverage: Use recommended water volume to ensure good coverage; coverage and dilution matter for absorption and efficacy.
  
• Waiting Period: There is a pre-harvest waiting period — ensure not to apply close to harvest. As per label, for paddy the waiting period is 27 days from last application to harvest.
  
• Bee safety & aquatic caution: Avoid spraying during active bee foraging; avoid application near aquaculture or water bodies.
  
• Crop restriction: Only use on paddy — do not apply on non-recommended crops.
  

Conclusion and Final Thoughts

For paddy farmers — especially in regions where hopper infestation is a recurring problem — Curbix® Pro represents a modern, reliable and effective insecticide. Its dual-mode action (Ethiprole + Pymetrozine), WDG formulation, and targeted efficacy against Brown Plant Hopper and White-Backed Plant Hopper make it a smart choice for protecting rice crops.

Proper, timely application — following recommended doses — can help ensure healthy rice canopy, prevent hopper burn, and secure higher yields. Moreover, because of its resistance-management properties, it offers a sustainable solution over repeated cropping cycles.
