Researchers seek insight on emerging controlled environment agriculture trends
Greenhouse operators are encouraged to participate in the 2023 State of Controlled Environment Agriculture survey. IUNU, a technology company that specializes in AI and computer vision solutions for the agriculture industry, and the University of California Agriculture and Natural Resources are conducting the survey to gain insights on emerging trends and challenges to share with the controlled environment agriculture industry.
The survey takes approximately 25 minutes to complete. All growers using CEA – greenhouse, high tunnel or indoor – are invited to participate. All data collected is confidential and shared only as anonymous trends. No identifying information is ever shared. Growers who participate will get early access to the survey results report and will get access to an exclusive webinar to discuss the results with the authors of the report.
The fourth State of CEA Survey can be completed at https://www.surveymonkey.com/r/FVXJSY9.
The report, first released in 2016, was formerly titled “State of Indoor Farming” and managed by Artemis, which was acquired by IUNU in 2021.
This year, IUNU has expanded the survey to include the different leading segments of the controlled environment agriculture industry: greenhouse fruit and vegetable, and greenhouse ornamental production.
UC ANR's VINE agrifood technology innovation program, Global Controlled Environment Agriculture Consortium (GCEAC), and UC Davis-led AI Institute for Next Generation Food Systems (AIFS) are collaborating on the report.
“An industry-led, market-driven approach to guiding innovation priorities and investments is critical as we consider the future of indoor farming,” said Gabe Youtsey, UC ANR chief innovation officer and co-founder of The VINE. “I'm thrilled to partner with IUNU on the development of this State of CEA report with our UC innovation teams from The VINE, GCEAC and AIFS to create a robust state of CEA report that will guide our CEA open innovation priorities this year.”
Since the survey launched in 2016, more than 500 growers have participated in the survey and more than 2 million people have downloaded the report. The industry reports have become one of the most widely circulated and respected sources of industry data.
"This report is a trusted resource for the industry and we're thrilled to bring it back in an expanded capacity,” Allison Kopf, IUNU chief growth officer, said. “Over the past year, we've seen a swell of news around our industry. This report will go deeper into those stories and share data on how companies are performing, big market opportunities, and the real challenges growers are facing.”

Founded in 2013 and headquartered in Seattle, IUNU aims to close the loop in greenhouse autonomy and is focused on being the world's leading controlled environment specialist. IUNU's flagship platform LUNA combines software with a variety of high-definition cameras – both fixed and mobile – and environmental sensors to keep track of the minutiae of plant growth and health in indoor ag settings. LUNA's goal is to turn commercial greenhouses into precise, predictable, demand-based manufacturers that optimize yield, labor and product quality. www.IUNU.com

Common causes of abiotic disorders include too much or not enough water, compacted soil, nutrient deficiency (often caused by imbalanced soil pH), excess soil salinity, too much heat or sunlight, herbicides, air pollution, and mechanical injuries.
Abiotic disorders can develop for several reasons:
- the site was not well prepared before landscaping,
- the plants were improperly planted,
- the plant species is not well adapted to conditions at that location,
- the plants did not receive the correct cultural care.
Avoid abiotic disorders by giving plants the right amount of water, sunlight, and nutrients. You must water plants properly, and the soil must drain well. The soil must contain the correct nutrient levels, pH, and salinity. Fix any extreme light or temperatures issues like too much sunlight. Protect plants from herbicide and fertilizer damage as well as from mechanical injuries.
When you suspect an abiotic disorder, find out both the species and variety of the plant so you know the plant's expected appearance and its specific cultural needs. Inspect the plant and surrounding plants for symptoms. Some abiotic disorders can be recognized by their characteristic damage symptoms (e.g., distorted, discolored, or dying foliage). However, diagnosing the cause of disorders can be difficult. Plants will react differently to abiotic issues depending on their age and specific variety. Different abiotic causes can produce the same symptoms, and more than one cause can affect plants at the same time.
To solve plant problems, it's important to distinguish abiotic disorders from similar-looking damage caused by pests such as insects, mites, nematodes, pathogens, and vertebrates. See Table 1 for details.
|Plants affected||Unrelated||One type or closely related|
|Plant age||Various ages||Same age more likely|
|Pattern of symptoms||Regular or uniform||Random or irregular|
|Rate of development||Sudden onset||Slow, worsens over time|
|Spread||Does not spread||Infectious, spreads on host over time|
|Signs||No evidence of pest or pathogen||Presence of pest, mycelium, mushrooms, rust, pustules, bacterial ooze, honeydew, frass|

If you have eucalyptus trees, you might have noticed white, crusty growth on the leaves. Or maybe you saw a sticky, blackened mess of fallen leaves under a eucalyptus tree. These are signs of the redgum lerp psyllid, one of the most common psyllid pests that damages eucalyptus trees in California.
The adult psyllid is very small and as nymphs, they are concealed under a waxy cap, or lerp. As they feed, they excrete honeydew which can lead to the growth of black sooty mold, the source of those sticky leaves under the tree.
Although under biological control in coastal areas, this pest is still a problem under some growing conditions and on specific Eucalyptus species. Cultural practices to manage lerp psyllids, such as avoiding fertilization of eucalyptus trees and pruning only when and where needed, can help reduce lerp psyllid problems.
The newly revised and expanded Pest Notes: Eucalyptus Redgum Lerp Psyllid, authored by entomologists Timothy D. Paine, UC Riverside; Kent M. Daane, UC Berkeley and UC ANR Kearney Agricultural Research and Education Center; Steve H. Dreistadt, UC IPM Program; and Raymond J. Gill, California Department of Food and Agriculture, contains detailed information about the identification, biology, and management of this pest.
This revision has more information about the lerp psyllid's biology and damage they cause on eucalyptus, a list of eucalyptus trees resistant to this pest, and an expanded section on biocontrol, with detailed information about the imported parasitic wasp that only attacks redgum lerp psyllid.

Pampasgrass and jubatagrass facts
Pampasgrass (Cortaderia selloana) is a common ornamental landscape plant that readily naturalizes throughout California's coastal areas and some interior regions. Historically, pampasgrass was planted for erosion control, but it has since escaped cultivation and spread along sandy, moist ditch banks throughout coastal regions of southern California. Pampagrass can also grow in the hot, dry climate of inland areas of California.
A similar-looking invasive grass, jubatagrass (Cortaderia jubata) is more widespread and aggressive and is a major pest in coastal redwood forest areas. Jubatagrass thrives in cool, foggy environments and does not tolerate temperature extremes or drought.
Both pampasgrass and jubatagrass outcompete native plants; a single floral plume can make 100,000 seeds in a year. They create fire hazards with excessive build-up of dry leaves, leaf bases, and flowering stalks. The tough leaves have serrated edges that can easily cut skin.
What can you do?
Plant other ornamental grasses in your garden or landscape. Many species including native grasses can be planted that resemble pampasgrass but aren't problematic. This includes several species of Muhlenbergia: deer grass, white awn muhly, and Lindheimer's muhly. California native Pacific reedgrass grows well on the coast and is deer resistant. For a large, tough bunchgrass, try giant sacaton, a native of the Southwest. Giant wildrye, another California native, will grow into dense stands that attract birds.
