Bayer Fenos QUICK Insecticide — Fast knockdown + lasting control (800-word guide)
Introduction of Bayer Fenos QUICK Insecticide
Bayer Fenos QUICK is a modern, broad-spectrum insecticide designed to deliver both quick knockdown and longer residual control against chewing and sucking pests. It’s a premix combining two complementary active ingredients that give growers fast action on field pests while helping manage resistance when used as part of a sound IPM plan.

Technical name (active ingredients)
Fenos QUICK is a suspension concentrate (SC) premix of Flubendiamide 8.33% w/w + Deltamethrin 5.56% w/w (SC). In short: a ryanoid-receptor modulator (flubendiamide) paired with a synthetic pyrethroid (deltamethrin). The two molecules act on different insect nerve targets — flubendiamide primarily affects ryanodine receptors (muscle/nerve regulation) while deltamethrin affects sodium channels — which gives both stomach and contact activity and helps slow resistance build-up.
Recommended dose (practical application)
- Dose per acre: 100–125 ml per acre is the commonly recommended field rate for many target crops such as cucumber (beetles, fruit fly) and chickpea (pod borer). Follow crop-specific label recommendations for exact timing and number of sprays.
- Dose per pump / per spray tank: Many labels and distributor instructions list 10 ml per 15-litre hand-pump as a practical small-scale measure — convenient for vegetable growers. That equates to ≈0.67 ml per litre when mixed into a 15 L tank.
Note on spray volumes: per-acre dose (100–125 ml/acre) is the amount of product applied to the whole acre regardless of total spray volume; if your spray volume per acre differs (for example 200–800 L/ha), calculate the concentration accordingly and ensure even coverage. Always follow the official product label for your region.

How it works (modes of action)
The combination provides:
Rapid knockdown from deltamethrin (contact activity), reducing active pest pressure quickly.
Effective stomach action and longer residual control from flubendiamide, which is especially useful against lepidopteran pests (borers and caterpillars).
Together these modes of action make Fenos QUICK effective for both immediate control and longer protection, while using two different biochemical targets helps with resistance management when rotated appropriately.

Key benefits
- Fast and visible knockdown: Growers report quick reduction in active pests after spray, improving immediate crop protection.
- Longer persistence: Flubendiamide’s stomach poison effect gives residual control, reducing the need for very frequent re-sprays in many crops.
- Broad-spectrum utility: Effective on common chewing pests (caterpillars, pod borers, beetles) and certain homopteran pests; useful in vegetables and pulses where those pests are problematic.
- Resistance management advantage: Two different modes of action in one formulation makes it easier to manage resistance compared with single-mode chemistries.
- Convenient dosing for smallholders: Pack sizes and a 10 ml per 15 L pump guideline make it easy for small-scale applications.
Practical tips for best results
- Apply at the right time — target larvae or early infestation stages for maximum efficacy. For pests like pod borer and fruit fly, timing relative to crop phenology matters.
- Ensure thorough coverage of foliage and fruiting parts; flubendiamide acts via ingestion and needs larvae to feed on treated tissue.
- Rotate modes of action — don’t rely solely on Fenos QUICK throughout the season. Rotate with other chemistries and integrate biological controls to reduce resistance risk.
- Observe re-entry and pre-harvest intervals stated on the local product label; these vary by crop and jurisdiction. Always follow label-legal restrictions.
Safety & environmental notes
Fenos QUICK contains synthetic insecticides—use appropriate PPE (gloves, mask, protective clothing) when mixing and spraying. Avoid spraying during active pollinator foraging times and follow buffer zone and water-body precautions on the label. Dispose of empty containers as per local regulations.

Final opinion
Bayer Fenos QUICK is a practical premix for growers needing quick knockdown plus residual control against chewing pests in vegetables and pulses. Its 100–125 ml/acre label rate and convenient small-tank guideline (10 ml/15 L pump ≈ 0.67 ml/L) make it easy to use, while the dual-mode formulation supports resistance management when used sensibly within an IPM program. Always consult and follow the official product label for crop-specific doses, pre-harvest intervals, and safety instructions.
