Rapid Crop Health Insights
Right Where You Farm

Look Inside the Leaf.™
Croptix delivers fast, easy, and accurate crop data, providing essential nutrition and disease insights to help improve yields.

Croptix is a precision agriculture platform for in-field early detection of crop nutrition and disease. We help farmers spot problems and detect nutritional deficiencies before they are visible. With our technology – faster and less expensive than legacy testing – farmers can make informed decisions that improve yield and optimize resources.

Problem: Laboratory crop health tests
are slow, expensive, and inconsistent

Farmers lab testing leaves in a bag for crop testing
Farmers have better things to do than pluck leaves from their crops, stick them in a bag, mail them to a faraway lab -- and then wait weeks for the results.

Discover the root cause using real-time data. Croptix is a precision agriculture platform that gives farmers accurate nutrient information and early disease detection. Traditional lab methods are slow and costly, often leading to missed opportunities for optimal crop management. Croptix provides farmers with real-time granular plant nutrition information and early disease detection, enabling growers to make informed decisions when they count.

Disease Spotlight: Citrus HLB

Citrus growers know all too well the effects of the deadly citrus greening or Huanglongbing (HLB) disease. Caused by a bacterial pathogen (Candidatus Liberibacter asiaticus), it is carried tree to tree by the Asian Citrus Psyllid (ACP). The bacteria can reside in a tree for many months prior to causing visible symptoms, slowly killing the tree while it serves as a host for HLB to be spread to other trees. The only way to prevent the rapid spread of HLB is to detect it early, eradicate infected trees, and improve management techniques to contain ACP. 


Originally found in Asia, HLB is spreading devastation around the globe. In the United States, HLB was first detected in Florida in the late 90’s, decimating production by over 60% in a decade. HLB is now hitting Texas and Southern California. Croptix has been partnering with forward-looking growers to mitigate the spread before it’s too late.

Technology Spotlight
"Molecular Ultrasound" for Plant Health

Look Inside the Leaf™
We Don’t Look At It…We Look In It.

Similar to how an ultrasound uses sound waves to image biological structures, our patented Croptix technology uses light waves to characterize the molecular and cellular structures inside plant leaves [read more...]. 

Croptix’s handheld, field-use miniature spectrophotometer captures light that has diffused in and re-emerged from the leaf. This “optical fingerprint” is analyzed in real-time by machine learning algorithms to accurately detect disease,  nutrient deficiency, and water stress. Croptix assesses crop health long before you can see issues, giving you a head start to take preventative actions.

Croptix Solutions

Manage and Mitigate HLB.
The only way to prevent its spread is through proactive management. Croptix has the most practical solution that is both affordable at scale and sensitive enough to screen individual trees early, before the disease spreads throughout a grove. The Croptix solution provides a monitoring and remediation program that works together with the industry's plan to fight HLB.

Croptix Nutrition Assessment

We are conducting in-field laboratory trials on groundbreaking nutrition analysis from in-situ crop leaves. Please Contact Us to learn more or participate in future trials.

Get Started with Croptix

Schedule a call and we will begin reviewing your operation for high-risk areas and vulnerabilities.


After identifying the vulnerable locations, we determine the number of tree tests required to protect each area.


We provide you with a quote that maps the planned route for screening on each block. A certified Croptix service provider will contact you within 1-2 weeks before the estimated service date.


Once the screening is completed by the service provider, you receive a detailed results report delivered to your email inbox within 1-2 days.

About Croptix

From Lab to Field

Dr. Perry Edwards and Dr. Zhiwen Liu founded Croptix (originally Atoptix) to translate innovative sensor technology developed by researchers at Penn State into solutions that can have a meaningful and marketable impact outside of the laboratory. Their insight was taking spectrophotometer miniaturization from the benchtop to handheld devices uniquely suited for non-invasive tissue sampling. They successfully applied their combined expertise in optical engineering with their team of engineers and other scientists to develop the Croptix platform, a convenient, field-deployable solution for farmers to effectively measure nutrition in situ and screen for crop diseases. By combining miniature spectrophotometers with big data and AI, their invention is a new tool in the field to improve global food security. Croptix was awarded highly competitive NSF SBIR Phase I and Phase II grants to develop and commercialize the technology.

We are a passionate and devoted group of individuals determined to completely transform the way growers and farmers manage their crops. Learn more about us below:
