Mode of action and chemical profile
- Active ingredient: Fluopyram belongs to the pyridinyl-ethyl-benzamide chemical class (FRAC 7).
- Biochemical action: Selectively inhibits mitochondrial respiration in the Complex II (succinate dehydrogenase) pathway of target nematodes and fungi.
- Rapid nematicidal effect: Causes rapid paralysis of juvenile nematodes in the root zone within hours of exposure, preventing root penetration and gall formation.
Target nematodes and registered crop uses
- Root-knot nematodes (Meloidogyne incognita and Meloidogyne javanica) causing root galls, stunting, and vascular wilting.
- Registered for major horticultural crops including tomato, capsicum, cucumber, banana, and pomegranate.
- Also provides systemic protection against powdery mildew infections during early vegetative growth.
Chemigation application and stewardship
Velum Prime is designed for application via drip irrigation (chemigation) or root drenching during nursery planting or shortly after transplanting. Ensuring the root zone is moist prior to application ensures uniform distribution in the active rhizosphere. Adhere strictly to the CIB&RC label recommendations and protective equipment guidelines.

Common questions
What is the active ingredient in Velum Prime?
Velum Prime contains Fluopyram at 34.48% w/w formulated as a suspension concentrate (SC).
How is Velum Prime applied to crops?
It is primarily applied through drip irrigation (chemigation) or as a targeted root drench around the base of plants during early crop establishment.
Why are root-knot nematodes dangerous to vegetable crops?
Root-knot nematodes burrow into roots and cause swelling (galls), severely restricting water and nutrient uptake, leading to stunting, wilting, and secondary fungal infections.
