LG Redwald – Taming the Beast!

Limagrain’s newest wheat addition to the 2023-24 AHDB Recommended List, LG Redwald, follows in the footsteps of LG Skyscraper as the highest yielding feed wheat with a UK treated yield of 107% – sitting at 107% in the east and an impressive 109% in the west.

LG Redwald has shown this high yield consistency across regions and very testing seasons of weather. Its high untreated yield of 92% reflects its very good disease resistance, especially for Septoria tritici.

How to get the best out of LG Redwald

1. Adjust Seed RatesLG Redwald is a high tillering, big biomass plant type, so consider a lower seed rate. Limagrain trials over several seasons show that reducing the seed rate by 20% had no effect on overall yield performance, with better lodging resistance.

2. Straw StrengthLG Redwald is a taller variety (94cm) with a big biomass, so a well targeted, robust, split PGR programme is recommended. If the desired early split timings are not achieved, then the inclusion of a late PGR (Cerone or Terpal) is advised.

3. Drilling Date – Do not drill LG Redwald too early, as it does not have the characteristics associated for the early drilling situation. It suits the standard drilling window of mid-October onwards and can be drilled to the end of January. For growers in the north, the drilling date can be pulled back to the beginning of October.

4. Soil Type LG Redwald benefits from being grown on water retentive soil types; not lighter soil types associated with drought situations. Reduce seed rates and implement a good PGR programme for heavier/ fertile soils.

5. Rotational PositionLG Redwald performs well as a 1st or 2nd wheat. Sitting as the highest yielding wheat (109%) in a 2nd wheat situation, it is a valuable variety to improve gross margins in this challenging situation. It has good tolerance to take-all, but a low rating for eyespot and should be treated accordingly.

6. Fungicide ProgrammeLG Redwald has good disease resistance for Septoria tritici, and both Rusts – we advise that all crops should be monitored and treated accordingly.

Whilst trials show that a robust on-farm fungicide strategy should be implemented, a T0 spray may not be required, depending on disease pressure. However, a robust T3 fungicide is important for protection against Fusarium, and as it is a later maturing variety, there are benefits from maintaining green leaf canopy to maximise grain fill.

7. InsecticideLG Redwald has OWBM resistance.
