Key Takeaways
- NewLeaf Symbiotics introduced Terrasym VT, a transplant-specific biostimulant designed to support vegetable crops during early-season stress.
- The product received California approval in late 2025 and is now available in major U.S. vegetable-growing regions.
- Terrasym VT demonstrated yield increases in strawberries, tomatoes, cucurbits, and other specialty crops.
- Trials reported an average 2.3-ton/acre yield gain in processing tomatoes across 20 large-scale farm trials from 2022–2024.
- The biostimulant leverages NewLeaf Symbiotics’ proprietary PPFM strain library of 12,000 microbial candidates.
NewLeaf Symbiotics Introduces 2026 Transplant Biostimulant
NewLeaf Symbiotics Expands PPFM-Based Solutions for Specialty Crop Growers
Growers preparing vegetable seedlings for field transplanting will have a new tool for the 2026 season as NewLeaf Symbiotics launches Terrasym VT, a biostimulant designed specifically to help crops withstand early transplant stress. The product received approval for use in California in November 2025, enabling deployment across key U.S. vegetable-producing areas.
Terrasym VT is engineered to improve nutrient uptake and minimize abiotic stress during the vulnerable transition from greenhouse to open field.
“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,” said Aaron Kelley, Chief Commercial Officer of NewLeaf Symbiotics. “These plant benefits result in more fruit being harvested when compared with the grower standard practice.”
NewLeaf Symbiotics Validates Multi-Crop Yield Performance
Field Trials Highlight Consistent Wins in Tomatoes, Strawberries, and Cucurbits
Extensive testing—including greenhouse evaluations, small-plot studies, and multi-year commercial field trials—demonstrates the performance of Terrasym VT across a broad range of specialty crops. In processing tomatoes, Terrasym VT delivered an average 2.3-ton per acre yield increase across 20 large-scale trials between 2022 and 2024.
Growers have flexibility in application, with the biostimulant suitable for pre-transplant drenches or dripline application after planting.
PPFM Technology Remains Core to NewLeaf Symbiotics Innovation
Strain Selection from a 12,000-Member Library Enables Crop-Specific Synergy
Terrasym VT reflects the company’s leadership in Pink-Pigmented Facultative Methylotrophs (PPFMs). NewLeaf Symbiotics draws from a library of 12,000 strains, selecting combinations with genetic traits best suited for vegetable transplant performance.
“VT technology has been tested for more than 8 years… so we can deliver consistent performance for fruit and vegetable transplant production,” Kelley noted.
