Dr. Tarah Sullivan is Assistant Professor of Soil Microbiology at Washington State University. In this interview, Tarah discusses how the plant microbiome mirrors the human gut, the ways in which soil microorganisms can alter the bioavailability of micronutrients and metals for plants, why plants in alkaline soils can be deficient in iron when the soil is not, if cover crops can improve soil microbial communities, and what is next for her research. Tarah’s research emphasis is on linking the...


126: Developing New Irrigation Technology for a Fraction of the Cost

Greg Pennyroyal of Wilson Creek Winery and Vineyards was looking for soil moisture systems and found that the products available in the market were all expensive, proprietary systems that did not meet the needs of small block Temecula vineyards. He partnered with Reinier van der Lee, CEO of Vinduino, to reverse engineer the technology to develop a product that would give the same results for a fraction of the cost. They have expanded this project over the last five years to collect more and...


125: Using Grape Grower Demographics to Influence Climate Change Adaptation

There are numerous tools and technologies to improve irrigation efficiency but by looking at grower demographics, we can better predict which growers will implement best management practices. Plus, we can learn how to educate all growers to improve adoption. Nicholas Babin, Assistant Professor of Natural Resources Management and Environmental Sciences at California Polytechnic State University, conducted a two-year study to assess Paso Robles California AVA grape growers’ thoughts around...


124: Virginia Creeper Leaf Hopper in Vineyards

While many growers are familiar with the Western Leafhopper, they may not know as much about the Virginia Creeper Leafhopper. Houston Wilson, Assistant Cooperative Extension Specialist in the Department of Entomology at UC Riverside and Director of UC Organic Agriculture Institute has been studying the Virginia Creeper Leafhopper and potential biological controls. Leafhoppers are pierce and suck feeders. The insect removes small amounts of plant material causing a stippling effect on the...


123: What is Happening in Biologicals for Pest Management and Plant Health

Consumer demand for transparency and sustainability of their food system is leading to more and more agrochemical restrictions to address concerns for pollinators, noenicitinoids, and drift. Additionally, ESG (Environmental, Social, and Governance) investors are putting pressure on the chemical industry to improve their metrics. Pam Marrone, Founder and CEO of Marrone Bio Innovations outlines the market, status, and potential for biologicals in this excerpt from our 2020 Sustainable Ag...


122: Preserving Agriculture Land to Combat Climate Change

Maintaining agricultural land can be a solution to climate change. Renata Brillinger, Executive Director at California Climate & Agriculture Network (CalCAN), and her team are working to incentivize sustainable practices like composting, cover crops, and solar pumps at farms. They promote four grant programs that help farmers and ranchers have a positive impact on the planet and their bottom line. The first is to prevent urban sprawl by funding easements to maintain working farmland. The...


121: Regenerative Agriculture (Rebroadcast)

David R. Montgomery defines regenerative agriculture as leaving the land better off and more fertile as a consequence of cultivation. David studied geology at Stanford University before earning his Ph.D. in geomorphology at UC Berkeley. Today he teaches at the University of Washington where he studies the evolution of topography and how geological processes shape landscapes and influence ecological systems. In this research, he has defined three principles to build soil fertility; minimal...


120: Autonomous Drone Vineyard Spraying

Imagine improving both the efficiency and safety of your team with autonomous drone vineyard spraying. That is exactly what David Goldfarb and the team at Clos de la Tech are trialing in their vine rows. Although this technology has been used in Japan for a number of years, it is new to the United States. Initially, they looked to drones as a way to scout for pests. Spraying was limited due to the small capacity of the machines. Then an advancement inspired by COVID stadium sanitation...


119: Vine Mealybug 101: Species Identification, Lifecycle, and Scouting to Create an IPM Program

The first pillar of any successful IPM (Integrated Pest Management Program) is to know the pest you want to manage. Emily Symmes, Entomologist and Technical Field Manager at Suterra, addresses the basics of vine mealybug (VMB) in grapes in this expert from the 2020 Sustainable Ag Expo. VMB are phloem eaters, piercing the trunk, canes, and berry clusters and vectoring leafroll-associated viruses. In high populations, they will weaken the vines and can cause vine decline and death. Their...


117: Grapevine Mildew Control with UV Light

UV lamps have been used in the medical field, food processing, and sterilization for 75 years but application on plant disease management only began in the 1990s. UV light is a natural component of sunlight. The most harmful wavelengths like UVC are screened out by our ozone layer. DNA damaging UVB does reach the surface, however, most organisms can utilize blue light to repair the damage. David Gadoury, Plant Pathologist at Cornell University, is part of a large team of international...


118: Managing Rodent Pests in Vineyards with Integrated Pest Management

When it comes to vertebrate pests, an integrated pest management plan is important for any crop, including vineyards. The best tactic to manage human-wildlife conflict is specific to each situation. The grower needs to consider the impact on non-target species, mode of action, and legality. Traps are not always species-specific, one or multiple pests may need to be controlled, and regulations are constantly changing. Roger Baldwin, Cooperative Extension Specialist within the Department of...


116: Using Nudge Theory to Improve Irrigation Practices

How can values, beliefs, and attitudes around irrigation improve water efficiency? That is exactly what a recent California Department of Water Resources (DWR) grant project aimed to discover. Grant recipient, Vineyard Team, worked with 59 growers over three years to conduct irrigation-related behavior interviews, Distribution Uniformity evaluations, and determine if continued interaction (nudges) with the grower would increase the adoption of irrigation best management practices in...


115: Examining Plant Nutrient Mobility with SAP Analysis

Plant SAP analysis gives farmers insight into how the plant can take up and mobilize nutrients. Traditional tissue testing is usually done at the top of the plant, sampling only the youngest leaves. SAP Analysis is actually a pair of tests, comparing nutrients in young and old leaves to see what is being taken up today and how the nutrients are moved around. Test results compare levels in young and old leaves across 24 different nutrients. One important comparison is Nitrogen efficiency, so...


114: Designing a Vineyard for Year-Round Sheep Grazing

Numerous vineyards have utilized sheep and goats for grazing but most only during the winter. Kelly Mulville was on a mission to design a vineyard for year-round grazing to restore the ecosystem with livestock.
