Master Seeds RESERVED seed is held back from the previous harvest for growers who require early seed supply for the following year.
It is cleaned, then germination tested and treated in June/July and delivered immediately. It has all of the usual Master Seeds benefits, but with the peace of mind of being able to reserve your priority seed, ready and tailored as you need it, to meet your early drilling requirements.
Securing your seed supply with RESERVED seed means that it will arrive on farm, in advance, at a convenient time for you -avoiding logistical problems at the time of drilling.

Please get in touch with your usual Agrii Agronomist or Seed Specialist for more information, or contact the Agrii Seed Desk on 01277 898202 or

Seed Treatment

Cereal Seed Treatments

Seed treatments are an affordable and effective way to optimise seed germination, plant establishment, early growth and yield potential. Our range of available seed treatments include:

  • Beret Gold
    Controls the seed and soil borne diseases of winter and spring wheat. It is based on a fludioxonil and has low dust and excellent flowability through the drill.
  • Redigo Pro
    Controls the seed and soil borne diseases of wheat and spring barley, oats, rye and triticale – it’s the latest formulation from Bayer CropScience to improve, handling, reduce dust and further improve loose smut and Fusarium control. It is based on a combination of prothioconazole and tebuconazole.
  • Rancona iMix The preferred base treatment for spring barley based on a combination of ipconazole and imazalil. It control loose smut, leaf stripe and seedling blight dieases. Agrii trials also show that it control seed-borne net blotch. It is also used with Vibrance Duo on barley to boost activity against loose smut and leaf stripe.
  • Raxil Star (Winter Barley Only)
    Raxil Star is a specialist winter barley fungicide which improves crop performance and quality with activity against difficult to control diseases.
  • Vibrance Duo
    Contains fludioxonil and sedaxane for control of a range of seed borne diseases in winter wheat, winter triticale, winter rye, spring oats and winter and spring barley. It also increases root and shoot biomass in both winter and spring crops
  • Signal
    Provides a zone of protection around the seed which kills or repels wheat bulb fly or wireworm in autumn/winter sown wheat and barley. It cannot be used in cereals drilled later than the end of January,
  • Latitude
    Currently the only specialist take-all seed treatment and is effective in all take all situations.
  • Take Off ST
    Two complimentary bio-stimulants to increase root growth and photosynthetic efficiency. Contains stabilised phosphite and pyro-glutamic acid. Increases winter hardiness and drought tolerance also improving root mass and emergence.
  • i-Man
    Highest load Manganese (450g/t) available and contains a collating agent that prevents lock-up by the soil. Applies 20% more Mn than New Manganese Solution and uptake is via the seed coat and roots to get more Mn into the plant.
  • Zax
    High load Zinc (450g/t) formulation. Responses even in non-deficient soils and consistent yield responses across a range of crops including wheat, barley and oats.
  • AgNition
    High load Copper (250g/t) formualtion that is perfect for copper deficient soils, high organic matter soils and phosphate-rich soils.

OSR Seed Treatments

Seed treatments are also applied to oilseed rape to control diseases and stimulate early vigorous growth. They include:

  • Integral Pro
    It is a biological control agent that colonizes the roots and releases exudates that control seed-borne Phoma, Alternaria and Rhizoctonia. It also stimulates root and shoot growth and controls low to moderate levels of Cabbage Stem Flea Beetle.
  • Take Off OSR
    A phosphite-based bio-stimulant that promotes early root development and boosts crop establishment and early crop vigour.

Grass and Roots Eng, Wales & NI 2023    Grass and Roots Scotland 2023    


The Master Leys range of grass mixtures offers full and comprehensive options for all types of farming systems and regions of the UK.
Working in close coordination with leading grass seed breeders throughout the UK and Europe, Agrii are able to access the best varieties to formulate the Master Leys portfolio. In addition to this, Agrii grows and produces over 80% of the grass seed used to produce Master Leys . This enables us to have a greater control over the quality of the seed we use and ensures that what goes into a Master Leys bag is of the highest possible standard.


To help reduce reliance on bought-in winter feed, we also offer a wide range of root seeds, which will help provide additional home grown winter forage.
By visiting trial sites and working closely with breeders, it means we are able to choose and offer the best varieties across all species of roots. Not only can we offer the best varieties, we can also offer advice on establishment techniques, nutrition for the crop and agrochemical inputs, to help you achieve maximum forage output.
Along with this, we can also offer advice on feeding the crop to help reduce wastage and to make sure the crop that you have grown is utilised to its full potential.

Cover Crops

Cover crops used correctly as part of your soil management strategy can deliver a range of benefits. The key element in improving soil health and productivity in the long term, is to increase your soil organic matter content. This is best done by selecting the correct cover crops for your farming operation. Please get in touch for details of the varieties that we have available, or for a copy of our
cover crops guide.
