For a decade, agtech got very good at measuring everything except the crop.   That's why growers and agronomists are stuck acting on ambiguity — over-treat and eat the cost, or under-treat and eat the loss. Heat, drought, nutrient stress, and early disease all look identical in a reflectance signal.   The fix isn't a smarter algorithm on the same data. It's a different signal: measure how the crop itself is responding — its physiology — and the picture stops being a guess and becomes a diagnosis.   So we mapped 161 crop-health companies across North America to see who actually does this. Only 4 measure the crop directly. And of the 54 platforms that stack the most sensors, not one includes a physiology signal.   That gap is the whole reason CredoSense exists. #agtech #crophealth #precisionag #agronomy #CEA

Powdery mildew attacks when leaves are dry. Pythium damages roots before the canopy shows clear symptoms. The harder problem is that the first visible signal is often ambiguous: midday wilt could indicate root disease, EC drift, or excessive VPD. The symptom may look similar, but the required response is completely different. That diagnostic gap—identifying the cause before visible damage and yield loss—is what CredoSense Inc. is built to address. #AgTech #PrecisionAgriculture #CropDiagnostics #GreenhouseTechnology #CredoSense

In a controlled-environment lettuce crop, the brown leaf margin is the last thing to go wrong, not the first. Tipburn remains one of the most stubborn limits on CEA lettuce in 2026, and it's still misread as a feed problem: the solution can carry plenty of calcium and the disorder appears anyway. It's a localized calcium shortfall in the youngest, fastest-expanding inner leaves — the tissue growing quickest yet transpiring least. Calcium moves on the transpiration stream, so where local transpiration stalls, delivery to that tissue falls behind demand and the young margins turn necrotic. Growers have engineered around this for years, and the tools earn their place: airflow fans to restart transpiration, a trimmed light integral, shorter cycles, foliar calcium. Each helps, each trades away yield, energy or labour, and none removes the underlying risk. The harder problem is timing. In Ohio State trials, low-transpiration conditions produced tipburn in every cultivar tested — up to 41% of leaves — even ones marketed as resistant (Ertle & Kubota, 2023). By the time that necrotic edge is visible, the shortfall it records is days old, and a single browned margin can make an otherwise perfect head unmarketable. Climate systems hold the room steady, but a dense inner canopy can sit in a low-transpiration pocket the room average never sees. That pocket is readable on the plant: how a canopy is transpiring and using water shifts before any margin browns. Reading that response bench by bench, before the necrosis, is where CredoSense works — surfacing the risk days ahead of the symptom, not after it. A question for growers: when tipburn shows up in your house, are you catching it on the plant, or on the packing line?

Great to see CredoSense technology supporting rigorous field research at the University of Toronto. Our smart soil chamber is now being used to measure soil respiration, methane, and other soil–atmosphere gas exchange processes by integrating with high-precision external greenhouse gas analyzers. For us, this is exactly where CredoSense Inc. is headed: from crop health diagnostics, to soil health monitoring, to climate and carbon research. Better field measurements are the foundation for better agronomic decisions, better soil management, and stronger evidence around nature-based climate solutions such as enhanced rock weathering. #CredoSense #SoilRespiration #SoilHealth #CropHealth #GreenhouseGases #Methane #CarbonRemoval #EnhancedRockWeathering #ClimateResearch #SoilScience #EnvironmentalScience #AgTech #ClimateTech #NatureBasedSolutions #UniversityOfToronto #UofT

Let's talk!

Every greenhouse grower has fought blossom-end rot (BER) the same way. And most have watched it come back anyway. The reason is a quiet misdiagnosis. BER looks like a calcium shortage — but it almost never is one. The substrate usually has plenty of calcium. The problem is that it isn't reaching the fruit. Calcium travels in one direction only: up the xylem, carried by the transpiration stream. Once it settles into a leaf, it stays there — it's never redistributed to the fruit. Inside the fruit, it's dropped off bit by bit as it travels, and the blossom end is the last stop in line. So when anything tips the plant's water balance — VPD swinging too high or too low, irregular irrigation, a salty root zone, root-zone temperature swings — the blossom end is the first tissue to run short. In susceptible varieties that can mean up to 50% of marketable yield, while the leaves stay a healthy green the whole time. And here's what makes it so frustrating: by the time the sunken lesion shows up, the failure that caused it happened days earlier. The climate screen looked normal. The substrate tested fine. The fruit looked fine. The plant wasn't. That gap — between when the plant starts to struggle and when the fruit finally shows it — is the whole game. Caught early, BER is a setpoint you adjust. Caught late, it's a cull pile. The lesion isn't a warning. It's a receipt — proof of a decision the plant made days earlier.

If you’re seeing symptoms, it’s already late. CredoSense Inc. detects stress before visible symptoms appear. Great insights- Azmain Al Faik

Pleased to share that our leaf chamber system was used in a newly published study in GCB Bioenergy examining greenhouse gas exchange from green roof foliage. The article, “Foliar Contributions to Methane and Nitrous Oxide Exchange in Urban Green Roof Systems,” uses our leaf chamber system to measure methane and nitrous oxide fluxes from green roof vegetation. This is not the full CredoSense Ag diagnostic platform, but it is an important example of how our core chamber technology can support rigorous plant–atmosphere gas-exchange research beyond conventional crop diagnostics. Green roofs are increasingly being evaluated not only for stormwater retention, cooling, and biodiversity, but also for their role in urban greenhouse gas dynamics. Measuring foliar-level gas exchange helps resolve a difficult question: how much do plants themselves contribute to methane and nitrous oxide exchange in these engineered urban ecosystems? For CredoSense, this is meaningful because it shows the broader scientific utility of our chamber architecture: portable, plant-level measurement in real-world systems where conventional instrumentation is often difficult to deploy.

Two years after Fusarium pepper wilt took an estimated 400 acres of Ontario greenhouse pepper out of production, the conventional toolkit hasn't closed the gap — and the reason is more revealing than the headline. A lot has been tried. Ontario Greenhouse Vegetable Growers, OMAFA, Agriculture and Agri-Food Canada/ Agriculture et Agroalimentaire Canada, and industry partners have been working this together since the outbreak emerged. Dr. Geneviève Marchand and Cara McCreary sampled commercial Ontario greenhouses for three years. Five fungicides — Thiram, Posterity, Medallion, RootShield Plus, Asperello — were tested. Sanitation protocols and steam sterilization between crops are standard practice. Research on partial cultivar resistance has been underway since at least 2017 (Cerkauskas, Canadian Journal of Plant Pathology). Healthy Hydroponics is developing strain identification services in collaboration with OMAFA and AAFC. So why isn't this solved? Marchand's three-year sampling returned an uncomfortable result. The Fusarium oxysporum species complex (FOSC) was present in most samples — but not universally, and rarely the same strain twice. The fungicide trials came back mixed, and the reason traced to a second pathogen entirely: Pythium was co-infecting plants alongside Fusarium, complicating every treatment outcome (Inside Grower, April 2025). The identified FOSC variant count climbed from 36 to 48 in a single year. Fusarium chlamydospores resist conventional sanitation. Resistant cultivars suitable for the novel outbreak are still in research, not commercial deployment. Cara McCreary's own public characterization: finding the cause is "like finding a needle in a haystack." Here's the part most agronomists in Ontario already sense but rarely say out loud. The conventional toolkit — chemistry, breeding, sanitation — assumes you can first identify what you're fighting. With this outbreak, you can't, reliably, before the 5–6 week window when symptoms finally appear on the plant. By then, the decision window has closed. The trade press itself is now calling for the missing piece. Inside Grower (April 2025): "a data-driven approach taking into account greenhouse environmental data coupled with high throughput biological and chemical data sources" is what would let applied research move forward. That's the gap CredoSense Inc. closes. Leaf-level physiology, genus-level spore counting for both Fusarium and Pythium, and continuous root-zone data — fused into one Ontario-specific diagnostic. We don't replace the fungicide, the breeder, or the sanitation crew. We give them something none of them have today: a real-time read on what's actually driving stress on a specific bench, this week. #ControlledEnvironmentAg #GreenhouseGrowing #PlantPathology #Fusarium #CropProtection #AgTech #OntarioAgriculture #PrecisionAgriculture

Most plant health monitoring are built around what we can see. That's the problem. Physiology changes first. Chlorophyll breaks down. Photosynthesis drops. Water transport fails. The color change — the yellow leaf, the wilting tip — comes days or weeks later. By then, the intervention window has already narrowed. FAO puts global crop losses from this delay in detection at 20–40% annually. Growers aren't blind — they're working with the wrong signal. That's the problem CredoSense is built to fix.
