Bayer Velum Prime is a systemic nematicide used for protecting tomato crops from root-knot nematode damage. It works by selectively inhibiting Complex II of the mitochondrial respiratory chain. Bayer Velum Prime helps reduce root-knot formation, weak root growth, poor nutrient uptake, and plant stress caused by nematode attack. It is applied through soil drenching or root-zone application, so the product reaches the area where nematodes actively feed. This nematicide supports healthier root development, better plant establishment, and stronger crop growth when used at the correct stage.
Key Features and Benefits of Velum Prime Nematicide:
Targeted Control: Bayer Velum Prime helps control root-knot nematodes that cause swelling, knots, and poor root development in tomato crops.
Systemic Action: It moves into the plant through the roots and helps protect the crop from nematode activity near the root area.
Rapid Pest Relief: Bayer Velum Prime affects nematode energy production, which makes nematodes weak, inactive, and less able to damage roots.
Low-Dose Application: Velum Prime gives strong nematode control with a small dose, making it convenient for root-zone treatment.
Velum Prime Uses:
Root-Knot Nematodes: Meloidogyne spp., root galling, root knots, weak root growth, poor nutrient uptake.
Tomato Root-Zone Protection: Early nematode attack after transplanting, poor crop establishment, yellowing due to damaged roots.
Nematode-Affected Soil: Fields with repeated tomato cultivation, light soil, warm conditions, and known nematode history.
Plant Growth Support: Better root activity, healthier seedlings, improved crop stand, and reduced nematode stress.
Bayer Velum Prime Dose:
Use Bayer Velum Prime as a soil drench or root-zone application. Velum Prime Dose Per Litre is around 0.6 ml per litre when using 250 ml in about 405 litres of water per acre, or around 1.25 ml per litre when using 500 ml in about 400 litres of water per acre. Velum Prime nematicide should be applied near the root zone so the solution reaches the active nematode area.
Crop | Target Pest | Dose per acre | Application Method | PHI |
Tomato | Root-knot nematode | 250 to 300 ml/acre | Soil drenching near root zone | Follow label |
Tomato | Meloidogyne spp. | 250 to 500 ml/acre, depending on application schedule | Drip irrigation or root-zone drench | Follow label |
Tomato | Root galling and nematode stress | 250 to 300 ml/acre | Apply around the plant base with enough water | Follow label |
How to Use Bayer Velum Prime:
Measure the required quantity of Bayer Velum Prime as per the acreage and nematode pressure.
Use this nematicide on healthy tomato seedlings after transplanting or as advised for the crop stage.
Fill the mixing tank or drip tank with clean water.
Add the measured amount to the water and mix properly.
Apply Bayer Velum Prime near the plant root zone, not on the upper leaves.
For soil drenching, apply the prepared solution around the base of each tomato plant.
For drip use, make sure the system is clean and the product reaches the active root zone.
Maintain enough soil moisture before and after Velum Prime nematicide application.
Avoid runoff because Bayer Velum Prime should stay near the roots for better action.
Do not apply Velum Prime on dry, cracked, or highly waterlogged soil.
Use the prepared Bayer Velum Prime solution on the same day.
Best Time to Apply:
Apply Bayer Velum Prime early after transplanting, before nematode damage becomes severe. Velum Prime nematicide works best when the tomato crop is actively growing, and the soil has proper moisture. Morning or evening application is better because field stress is lower. For fields with a known root-knot nematode history, early root-zone treatment gives better protection than waiting for heavy symptoms.
Frequency of Application and Re-entry Period:
Frequency of Application: One timely Bayer Velum Prime application can help manage early nematode pressure. In high-pressure fields, follow label-based repeat application guidance instead of applying without need.
Re-Entry Period: Avoid entering or working in the treated area for at least 24 hours after Velum Prime nematicide application without proper protective gear.
Compatibility: Do not mix Bayer Velum Prime blindly with fertilizers, insecticides, fungicides, biologicals, or plant growth products. Always do a jar test first.
Application Care: It works best when it reaches the root zone evenly, so proper water volume and soil moisture are important.
Resistance Care: Use Bayer Velum Prime as part of an integrated nematode management plan with crop rotation, healthy seedlings, soil care, and proper sanitation.
Safety Precautions and Handling:
Read the Bayer Velum Prime label carefully before mixing and application.
Wear gloves, mask, goggles, long sleeves, and protective footwear while handling Velum Prime nematicide.
Do not eat, drink, smoke, or chew anything during Bayer Velum Prime application.
Avoid direct contact with skin, eyes, and mouth.
Do not inhale mist, vapour, or spray droplets while preparing the solution.
Keep Bayer Velum Prime away from ponds, canals, wells, drinking water, and fish farms.
Wash hands, face, and exposed skin properly after using Velum Prime nematicide.
Keep children, animals, and unprotected workers away from the treated area.
