Mountain Valley MD Holdings Inc. (MVMD) has released updates from its Agrarius agricultural product trials, including results from citrus field work in Brazil and potato trials from the 2025 summer season. These programs are part of the company's strategy to support grower adoption of its licensed Agrarius plant-signaling technology.
In Brazil, MVMD is working with Farmatac to evaluate the product in mature Hamlin and Valencia orange blocks. Farmatac has completed assessments on both varieties.
For Hamlin, Agrarius-treated orchards showed improved plant condition and a productivity increase of about 125 boxes per hectare, a rise of roughly 15 per cent. Juice yield measurements indicated that treated fruit required 20 fewer boxes to produce one ton of juice compared with the control, bringing the total yield increase to approximately 22 per cent. Independent agronomists also reported a visual reduction in symptoms associated with Huanglongbing (HLB).
For Valencia, the treated block averaged 835 boxes per hectare, compared with 559 boxes in the control, reflecting a 49 per cent yield increase. Treated trees showed higher vigor and denser canopies, which the company said aligns with improved nutrient uptake and photosynthetic activity.
Two additional trials in younger orchards are nearing completion. MVMD expects results in the coming weeks, with preliminary observations described as similar to or stronger than those in mature blocks.
The company noted that reduced visible HLB symptoms continue to be one of the most notable findings. Dennis Hancock, MVMD president and CEO, said, "HLB has devastated citrus production globally, and we continue to see the United States Department of Agriculture state that there is no known cure available to producers. The early results we are seeing in Brazil are consistent with prior trials we have conducted and, if sustained across broader programs, suggest that Agrarius could represent the first scalable organic tool to help mitigate the impact of citrus greening disease while simultaneously improving orchard productivity and plant health."
In potatoes, MVMD reported results from 2025 summer harvest trials, showing an 18.49 per cent gain in productivity. Treated fields yielded 51,250 kilograms per hectare compared with 43,250 kilograms per hectare in the control plots. The company stated that these results reinforce observed performance across tuber crops.
Hancock said, "Whether in commercial-scale citrus orchards or staple row crops, the efficacy of Agrarius' performance appears to be reinforcing confidence among our partners."
Additional Agrarius trials are underway in Brazil and other regions on citrus, with data expected through 2026.
