Our experienced and qualified agronomists specialise in on-farm crop protection advice, on all arable and forage crops, to ensure efficient and targeted inputs produce optimal returns.

A full crop-walking service is provided by BASIS and FACTS qualified agronomists, which compliments the resources provided by our network of country stores. Our specialists are listed on the BASIS Professional Register and advice and recommendations are fully compliant with crop assurance schemes.

Our team of agronomists use their knowledge and experience to target inputs (be they agrochemical, fertiliser or seed) to specific situations to achieve full crop potential. Whether it is the latest SDHI cereal fungicide or brand new chemistry for use on newly sown leys, Wynnstay supply plant protection products from all the major manufacturers.

All our country stores have BASIS approved chemical storage facilities from where sprays can be collected. If a product is required that is not in stock, we can supply from our central chemical store.

Grassland Crop Protection

Grassland management is often overlooked for new leys, but by prioritising weed control early during establishment, you will achieve cost-effective, long-lasting control, resulting in a better quality crop in the long term.

The key is to get weeds under control while they’re just seedlings, to give the new ley a clean start and remove weed competition which can result in gappy swards. Generally, the most effective time to apply herbicide treatments is when the weeds are at the 2-4 leaf stage and once the grass (and clover if present) is large enough to be sprayed. By striking with an early herbicide application, an extremely high level of dock control can be achieved, better than at any other later timing during the life of the ley.

For established swards, the focus is on perennial weeds such as docks or thistles, and on invasive annual weeds such as chickweed. When targeting perennial weeds, it’s important to remember the fundamental principles of weed control:

  1. To kill the weed, we must get a lethal dose down to the root
  2. The weed must have sufficient green leaf area to take up the chemical applied
  3. The plant must be in active growth to move the chemical from the leaf down into the root

Correct product choice, an appropriate rate and timely application are crucial. ‘Clover-safe’ herbicides can be usefully employed. However, when there is a particularly challenging weed problem, it may be advisable to forget about saving the clover and use more effective ‘non clover-safe’ products. It is a straightforward process to re-establish clover at a later date. Early treatment not only allows you to get on top of weeds, but also allows the new sward to get a good, clean start without weed competition, so sown species persist for longer. The approach needs to be field specific in terms of the product recommendations, so talk to one of the Wynnstay agronomists, who can advise on the best approach for you.

Crop Nutrition Services

Wynnstay are able to offer a complete crop nutrition package from product supply through to fertiliser strategy and planning advice. The supply of product is fully supported by an expert advisory service — based on the bespoke needs of each customer. The Fertiliser Department, Agronomy Team and Arable Specialists can use their extensive technical knowledge to develop a fertiliser programme specific to each customers’ requirements. Wynnstay recognises the importance of analysing individual conditions to increase the efficiency of fertiliser – with the aim of maximising productivity and minimising expenditure.

A strategic approach requires in-depth examination and planning. Wynnstay’s team of specialists will use a number of methods to gather crucial insight to help make the best decisions on crop nutrition. This bespoke analysis will include an understanding of:

  • Soil analysis results
  • End use of the crop
  • Previous cropping and management
  • Environmental factors
  • Legislative requirements

Comprehensive Crop Nutrition Planning and Recording Service

EnCompass® is a comprehensive software program that generates accurate crop nutrition plans and field records. As well as producing field-specific Nitrogen recommendations, the software can also take account of Sulphur requirements and balances P and K off-takes or builds reserves. The fertiliser value of manures, slurries and other organic inputs can also be included in the calculations.

Nitrogen recommendations are based on RB209/SAC Technical Notes and refined using the CF N Calculator and N-Min® service. 

EnCompass®:

  • Maximises crop yield and quality by targeting inputs to plant requirements and crop potential
  • Generates accurate field and farm records for Management Plans, Cross Compliance, Nitrate Vulnerable Zones (NVZs), Traceability, Crop Assurance and Environmental Stewardship schemes
  • Provides detailed field operator sheets so that the spreader operator knows exactly what needs to be applied, where and when
  • Is recognised and reviewed annually by the Environment Agency

Modules are also available to create NVZ Compliance Reports, Manure Management Plans.
