Velum Prime
Velum Prime is a liquid formulation with a new mode of action that can be applied in-furrow to offer improved ease of use and significantly lower dose rates than traditional granules.

Controlling PCN populations is your first key step to ensure high-quality potato yields. When populations can remain in the soil for decades, it’s important to treat PCN at the start of each growing season as PCN can cause yield losses of up to 35% - costing UK potato farmers an average of £26M each year (AHDB).

Velum Prime is the first new nematicide to control potato cyst nematodes in 20 years. Across 26 UK trials targeting PCN it delivered an average yield increase of 3.3 t/ha, and with no harvest interval it can even be used on salad and early potato crops.
Velum Prime can be used in-furrow spray from the planter. It has a new mode of action that inhibits ATP production in mitochondria.
Offering a lower does rate over traditional granules, Velum Prime can be applied at 0.625 L/ha vs the suggested 30-55 Kg/ha application rate for granules.

Pests controlled
Velum Prime is effective against both species of potato cyst nematode (PCN): Yellow potato cyst nematode (Globodera rostochiensis) andwhite potato cyst nematode (Globodera pallida). However, in some soils with high organic matter, control of Globodera pallida may be less effective.
Application
Apply Velum Prime as in-furrow spray, 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.
Succeeding crops
Cardoons, celeries, Florence fennels and crops belonging to the category ‘other stem vegetables’ cannot be allowed as succeeding crops.
Varieties
Velum Prime may be used on all commercial varieties of potatoes. Whilst no additional data (crop safety and efficacy) has been provided, crops grown under plastic can be treated at the grower’s risk.
Velum Prime contains fluopyram (pyridinyl-ethyl-benzamide). As nematicides are not included in the mode of action classification scheme of IRAC, fluopyram is not assigned to any mode of action class by IRAC. However, fluopyram also controls certain plant pathogens and is classified by FRAC as a member of the Succinate-Dehydrogenase Inhibitor (SDHI) group of fungicides. A resistance management strategy in the crops where Velum Prime is applied also requires consideration of uses of other SDHIs for disease control.
Nematode Resistance
Velum Prime contains an active ingredient with a new mode of action for use as a nematicide. The resistance risk in nematodes is considered to be low based on experience of the use of organophosphates.
Potatoes
Where Velum Prime has been applied the first foliar fungicide application made to the crop must not be a member of the SDHI group.
