Improved Growth & Development

Witzenberg, Ceres - 2011

Randomised block trial

The C4L-treated area exhibited a visibly improved stand and greater vigour, with increased plant growth.

Enhanced Root Growth & Development

Witzenberg, Ceres - 2011

Randomised block trial

C4L treatment resulted in improved soil aggregation around the roots, indicating enhanced root-soil interaction and microbial activity, while the untreated roots showed weaker aggregation and less soil adherence.

Additionally, C4L-treated plants exhibited a denser, more vigorous root system with increased fine root development, compared to the less developed root network of the untreated plants.

Yield & Fusarium Incidence

Rhinestone

Op die Berg - 2017

4 Replicates

Randomised block design

The C4L programme delivered a 10% yield increase while reducing Fusarium incidence from 11.5% to 4.1%.

Onions were harvested in late December 2017, left to dry for three weeks, and had their leaves removed before being transferred to a storage facility. 

After eight weeks of storage, approximately 500 onions per treatment were evaluated for signs of Fusarium infection. 

C4L application dosage & timing:

  • 250 mL/ha

  • 2 Weeks post-transplant

  • + 28 days later

The C4L treatment significantly reduced Fusarium incidence from 13.4% to 7.1%.

Onions were harvested early January 2018, left to dry for three weeks, and had their leaves removed before being transferred to a storage facility.

After seven weeks of storage, approximately 500 onions per treatment were evaluated for signs of Fusarium infection.
