Clean seed and rapid germination – Zayndu launches new plasma system at CEA 4.0

Successful customer evaluations have brought forward the launch of Zayndu’s cold plasma systems, which uses activated air to disinfect seeds without water or chemicals.

Zayndu extends ‘try before you buy’ offer to on-site evaluations of new Z10 systems

The company is also extending its ‘try before you buy’ offer to enable customers to see the benefits of the complete system running in their own facilities. The new addition to the product range offers increased capacity and additional resilience and is being launched at CEA 4.0 on 6th and 20th May 2022.

Seed pathologist Dr Alberto Campanaro heads up the R&D facility at Zayndu; he says that the increased capacity machine has been requested by customers following evaluations with their own seed.

“So far, the biology team has used our Z10 to treat 60 varieties across 23 different species of plant. The seeds are disinfected and the pathogen load, germination rate and vigour are compared with the untreated seed.”

20 per cent increase in germination

“Customers have reported an increase in germination rate of up to 20 percent. However, a number of organisations have also told us that the 10-litre capacity was insufficient for many controlled environments.

“Working with these end users has been invaluable, it has enabled us to optimise the process, validate industry demand and co-design the larger machine.”

The Zayndu cold plasma system offers a chemical free, water free alternative way to disinfect seeds. The seeds are placed in its sealed drum and an electric current is introduced, splitting the air molecules into reactive oxygen and nitrogen species (RONS). This ‘activated air’ destroys bacteria and fungi, leaving just clean seed and fresh air.

Scientific studies have shown that the RONS change the surface of the seed coat, which increases water uptake during germination.

Alberto continues: “The demand for seed evaluations from potential customers has exceeded our expectations and is producing some fascinating results, particularly around optimising the exposure to activated air. We are seeing greater consistency in germination, faster germination times and improved plant development.

“We are looking forward to discussing these findings at CEA 4.0”

The company is offering the Z10 to customers for assessment to allow them to see the benefits in their own environment and to work with Zayndu scientists to optimise the protocol by species and variety.
