Timely advice as another wave of frosts threatens British crops.
BIOSTIMULANTS can act as an insurance policy for growers this spring, especially as another wave of frosts threatens to knock crops back.
So far, winter has been wet and with the exception of some sharp frosts, relatively mild – resulting in many autumn sown crops being further forward than usual.
However, David Newton, Timac Agro technical manager, is warning that this will not protect them from being damaged during cold spells which are likely to hit.
He says frosts could be detrimental for crops that are further forward in the growing season. “Frost susceptibility usually increases with lush growth, especially when there have been above average autumn/winter temperatures”.
“This can cause yield and quality loss in cereals, which is why applying a foliar biostimulant, such as Fertiactyl, will help mitigate against frost damage by ensuring increased root development, tillering and recovery from stress events.”
If crops can develop a robust root system, this encourages the uptake and mobilisation of nutrients, increasing their resilience and ability to bounce back from climatic stressors.
“You want to limit the number of times your crop is knocked back in a season,” David said.
“Every challenge your crop faces, the more it chips away at the potential yield – so whether it’s a substandard seed bed resulting in poor emergence, pest or disease pressures, or weather conditions – it all starts to add up.”
The key is to grow a crop that can tolerate stressors and recovers quickly.
“When stress does occur, the glycine betaine accumulation from a biostimulant stabilises the balance of water and mineral salts in the plant leaves, enabling them to keep functioning and photosynthesising,” said David.
In addition, Fertiactyl can be applied in February until the end of March, alongside T0 or T1 applications, so there is no need for the sprayer to go out more times than necessary.
