Chemical profile and cellular mode of action
- Pyridinyl-ethyl-benzamide class: Active ingredient Fluopyram belongs to the Succinate Dehydrogenase Inhibitor (SDHI) group (FRAC Group 7).
- Cellular respiratory inhibition: Selectively blocks Complex II in the mitochondrial respiratory chain of nematodes, paralyzing their movement and halting root penetration within hours.
- Nematicidal and fungicidal dual protection: Simultaneously suppresses soil-borne fungal pathogens while maintaining root health.
- Selective environmental profile: Highly lethal to plant-parasitic nematodes while exhibiting high safety toward non-target earthworms and beneficial soil bacteria.
CIBRC approved target crops and nematode species
Approved in Indian agriculture for controlling Root-knot nematodes (Meloidogyne incognita) in tomato, capsicum, cucumber, banana, and pomegranate. In commercial vegetable polyhouses and drip-irrigated orchards, applying Velum at transplanting prevents root galling, nutrient chlorosis, and secondary fungal wilt infections.
Drip irrigation application and safety precautions
- Apply exclusively through drip irrigation systems or directed soil root drenching; not recommended for foliar spraying.
- Pre-wet the soil root zone with plain water, inject the measured chemical dose through the venturi or fertigation tank, and flush lines thoroughly.
- Apply during early crop establishment to protect vulnerable young root tips from early nematode invasion.
- Observe the mandatory Pre-Harvest Interval (PHI) specified on the CIBRC approved label.

Common questions
What is the active chemical ingredient in Bayer Velum?
Velum contains Fluopyram at 34.48% concentration formulated as a Suspension Concentrate (34.48% SC).
How is Velum applied in vegetable farming?
It is applied directly to the root zone via drip irrigation systems or as a targeted basal soil drench around the plant base.
What are the telltale symptoms of root-knot nematode damage?
Stunted crop growth, yellowing foliage, mid-day wilting despite adequate moisture, and swollen galls or knots visible on roots upon uprooting.
