Velum PrimePlant Protection Product ComparisonPlant Protection Product ComparisonReport inaccuraciesReport inaccuracies

A liquid nematicide for potatoes and carrots. In potatoes it can be applied in-furrow at planting or as a broadcast spray to the soil surface and then incorporated to a minimum depth of 10 to 20 centimetres up to 72 hours before planting.

In carrots, Velum Prime can only be applied as a broadcast spray up to 72 hours before being incorporated to a minimum depth of 10 to 20 centimetres.

The flexible way to manage nematodes

The central appeal of Velum Prime is the flexibility it brings to yield protection and population management. The absence of a restrictive maximum residue limit or harvest interval means Velum Prime can be used with all crop types, from long-season potatoes to short-season salads. Similarly, it can be used on all commercial varieties of carrot.

For potatoes under high pressure situations, the greatest level of yield protection has been seen when Velum Prime is applied in sequence with a granular nematicide at either half or full rate. In less-than-high-pressure situations, Velum Prime applied alone may be sufficient to provide sufficient yield protection.

For carrots, the best protection has been achieved from a standalone application of Velum Prime.

Velum Prime also offers many practical advantages. It comes in easy-to-handle packaging and has a low application rate meaning there are fewer containers to handle and less waste to manage.

• Easy handling – dramatic reduction in nematicide bulk

• Easy application – just 0.625 L/ha applied in-furrow (potatoes) or as a broadcast spray (potatoes and carrots)

• Easy management – no restrictive harvest interval, so easy to use on any crop type

• Easy decision – make Velum Prime the core of your nematicide strategy

On every soil type, crop type and level of infestation across Great Britain, Velum Prime has been shown to be a valuable component of an integrated pest management strategy that will help protect land for the viable production of carrots and potatoes for the long-term.

In potatoes (ware, seed and salad crops),Velum Prime is effective against both species of potato cyst nematode (PCN), Globodera pallida and Globodera rostochiensis. In some soils with high organic matter, activity against G. pallida may be reduced.

Velum Prime can also be used for the reduction in spraing symptoms caused by Tobacco rattle virus transmitted by species of free-living nematodes. There is a risk that treated crops may still show symptoms of spraing and could be rejected by the processor. The extent to which spraing symptoms are expressed varies between varieties and this should be considered when selecting land for potato production.  

In carrots, Velum Prime can be used for a reduction in fanging caused by free-living nematodes.  

Pests Controlled

Potatoes

Velum Prime is effective against both species of potato cyst nematode (PCN): Yellow potato cyst nematode (Globodera rostochiensis) and white potato cyst nematode (Globodera pallida). However, in soils with high organic matter, control of Globodera pallida may be less than that achieved in other soil types.

Velum Prime can be applied for the suppression of free-living nematodes associated with the transmission of tobacco rattle virus, one of the two causes of spraing. There is a chance that crops treated with Velum Prime may still show symptoms of spraing.

Carrots

Velum Prime can be used for the suppression of plant parasitic nematodes and for the reduction of fanging caused by nematodes.

Parsnips

Under an extension of authorisation for minor use (EAMU) number 0288 of 2021, Velum Prime can be applied to parsnip crops for the control of free-living nematodes (Pratylenchus spp., Trichodorus spp., Paratrichodorus spp.).  The grower must be in possession of the EAMU before application to parsnip crops can be performed.

APPLICATION METHOD AND TIMING

Do not apply more than 250 g/ha fluopyram via soil treatment per calendar year.

Broadcast spray applications are restricted to potatoes once every three years and to carrots and parsnips once every two years.

Potatoes

Velum Prime can be applied by two methods.

Broadcast: Between February and June, Velum Prime can be applied as a broadcast spray up to a maximum of 72 hours before planting in 200-500 litres of water per hectare. It must then be incorporated to a depth of 10-20 centimetres. The broadcast spray can be applied either via a conventional boom sprayer or from an application system mounted to the same tractor as the tilling machine. It must be applied to the whole field ahead of cultivations or bed tilling.

In-Furrow: Velum Prime can also be applied as an in-furrow spray in 200-500 litres of water per hectare using on-planter application technology.  It is important to direct spray into the planting furrow and not onto the seed tuber. Application should be made using two nozzles per row; one at the front of the planting share and directed down into the furrow and the second at the rear of the share and directed so to spray the soil as it closes around the planted furrow.

If the crop is intended for processing consult the processor before use.

Carrots and Parsnips Apply Velum Prime as a broadcast spray between February and June up to a maximum of 72 hours prior to drilling in 250–500 litres of water per hectare.

It is essential that Velum Prime is thoroughly and evenly incorporated into the soil to a minimum depth of 10-20 centimetres, prior to drilling. Thorough incorporation of Velum Prime should be made by a rotavator or bed forming cultivation.

In situations where a de-stoned /de-clodded tilth is required, Velum Prime should always be applied to the de-stoned beds prior to bed-forming. Where front mounted sprayer systems are used, soil incorporation by the bed-former occurs immediately after application.

Where these systems are not available, Velum Prime will be applied to the de-stoned beds using a conventional boom sprayer, again in advance of the bed forming operation.

For crops drilled ‘on the flat’ (not de-stoned and not into beds) product application should be made by a conventional boom sprayer prior to power harrowing to a depth of 10–20 cm. Where a conventional boom sprayer has been used to apply the product to either the de-stoned beds or the flat soil surface, the soil incorporation must be made up to a maximum of 72-hours prior to drilling.

If the crop is intended for processing consult the processor before the use of Velum Prime.

Following crops

Cardoons, celeries, Florence fennels and crops belonging to the category ‘other stem vegetables’ cannot be grown as succeeding crops.

Varieties

Velum Prime may be used on all commercial varieties of potato, carrot and parsnip. While no additional data (crop safety and efficacy) has been provided, crops grown under plastic can be treated at the grower’s risk.
