Solutions to support potato growers

Option^®

Option is a fungicide for potato Late Blight disease control containing cymoxanil which has been the backbone of the UK blight programme for many years and continues to provide invaluable curative activity that can be combined with other AI's at any stage of the blight programme. Cymoxanil (Group 27) offers an additional MoA in addition to curative activity as part of an anti-resistance strategy in mixture with a fungicide partner. This is of particular value for single AI products

Formulation: Water dispersible granule containing 600g/kg cymoxanil.
Key benefits:

• Option contains cymoxanil, which is locally systemic and offers both preventative and curative control.
• It must only be applied in tank-mixture with specified formulations of partner blight materials.
• The combination of two active ingredients will also help to reduce the selection and build-up of resistant strains of fungi.

Titus^®

Titus is the mainstay of early season post emergence weed control in potatoes. Typically applied when weeds break through residual programmes or germinate late. Best control is achieved when weeds are small and actively growing (between 2-4 true leaves). Titus has activity on a wide range of difficult broad-leaved weeds, such as cleavers, chickweed, redshank, mayweed, brassica weeds and volunteer oilseed rape. It also has some excellent activity on some grasses, notably couch.

Formulation: 250 g/kg rimsulfuron
Application timing: in the spring pre-emergence of the crop up until the crop is 25 cm high. Best control is achieved when weeds are small and actively growing (cotyledon to 2 true leaves).
Application method: Sprayer
Key benefits:

• Suitable for use on all potato varieties excluding seed crops.
• Broad spectrum of activity including difficult broad-leaved weeds and grasses.
• It can be tank-mixed with metribuzin (on metribuzin tolerant varieties only), for improved control of knotgrass, fat hen and speedwells. However, mixtures with metribuzin will be antagonistic in terms of cleaver control.
• Use Vivolt at 0.1% v/v when applied alone or in a tank-mix.

BlueN^™

BlueN provides a crop with a unique way to capture nitrogen throughout the season, helping plants reach their marketable yield potential. The BlueN potato trials programme in 2024 showed an average marketable yield increase of 4t/ha and an average return on investment of £970/ha (potatoes £250/t and BlueN £30/ha).

Contains: Methylobacterium symbioticum.
Pack size: 3kg
Recommended rate: 333g/ha
Maximum no. of applications: 1 application per crop.
Application timing: when the crops are meeting in the row.
Application method: Foliar with sprayer.
Rainfast: 1 hour
Key benefits:
Enhanced plant growth and resilience.

• BlueN enhances plant growth and resilience by fixing atmospheric nitrogen directly in the plant. This process occurs throughout the growing season, resulting in marketable yield increases.

Provides a sustainable source of nitrogen.

• BlueN meets changing market expectations by providing a supplementary and sustainable source of nitrogen, without the risk of leaching or releasing additional greenhouse gases. BlueN reduces the dependency of nitrogen fertiliser uptake from the soil and ensures the plant has access to nitrogen all season long.
