Vegetable growers transitioning seedlings from greenhouse to field face one of the most vulnerable stages of crop production.
To help farmers better manage transplant shock and unpredictable growing conditions, NewLeaf Symbiotics has announced the launch of a new vegetable transplant (VT) biostimulant technology in California for the 2026 season.
The innovation, registered as Terrasym VT, is specifically designed to support vegetable transplants during periods of abiotic stress, such as temperature fluctuations, nutrient limitations and environmental pressure. Following regulatory approval in late November 2025, the technology is now available to growers across key agricultural regions in the United States.
Terrasym® VT has already demonstrated strong performance across a wide range of high-value specialty crops, including strawberries, tomatoes and cucurbits, delivering measurable yield improvements and stronger early plant establishment. The technology is built on NewLeaf Symbiotics’ expertise in Pink-Pigmented Facultative Methylotrophs (PPFMs), a specialised class of beneficial microbes that enhance plant performance through natural biological processes.
"NewLeaf VT technology is a combination of PPFM strains that work together to improve nutrient uptake and mitigate abiotic transplant stress to enhance seedling vigor," says Aaron Kelley, Chief Commercial Officer of NewLeaf Symbiotics. "These plant benefits result in more fruit being harvested when compared with the grower standard practice as a control in trials."
Growers can apply VT technology flexibly, either as a drench prior to transplanting or through the dripline after transplant, allowing seamless integration into existing crop management systems. This adaptability makes the solution particularly attractive for modern, efficiency-driven vegetable production.
NewLeaf Symbiotics is recognised as the global leader in PPFM research and development, with a proprietary library of more than 12,000 microbial strains. Each strain is selected based on its unique genetic characteristics and its ability to work symbiotically with specific crops. The strains used in Terrasym VT were chosen for their proven compatibility with vegetable transplants and their capacity to support consistent growth under stress.
"VT technology has been tested for more than 8 years in labs, greenhouses, small-plot field trials and on-farm large-scale field trials. NewLeaf puts that time and resource investment into our technology so we can deliver consistent performance for fruit and vegetable transplant production," says Kelley. "As we awaited critical approvals, like California, we were able to document strong results, including an average yield increase of 2.3 tons/A in processing tomatoes on 20 large scale farm trials from 2022-2024 when compared to grower standard practice."
As growers seek resilient, sustainable and yield-enhancing solutions, Terrasym VT positions itself as a powerful tool in next-generation vegetable production.
