Grower Resources

Your Home for all LODI RULES Resources

This page is designed for new and continuing LODI RULES growers. It is a collection of resources needed to certify your vineyards under the LODI RULES Sustainable Winegrowing program, including all documents, instructions, and contact information.

LODI RULES for Sustainable Winegrowing is California’s original sustainable viticulture certification program. Our certification process is rigorous, based in science, voluntary, and third-party accredited and audited. Click HERE or on the binder cover photo to the right to access a PDF with the current LODI RULES standards.

The information included in this page is intended to help make the road to certification a smooth one.

LODI RULES for Sustainable Winegrowing Certification Standards, Fourth Edition

The LODI RULES for Sustainable Winegrowing Certification Standards, Fourth Edition binder is your primary tool for navigating the certification process. Getting your hands on this binder is the first step to becoming LODI RULES certified. The binder is comprehensive and contains background on the program, instructions, and resources, and most importantly it outlines the 100+ standards. The binder is to be used in tandem with the online self-assessment website (see below). New Fourth Edition binders are available to pick up at the Lodi Winegrape Commission office. Contact to get your new binder mailed if you are unable to pick one up in Lodi.

The Fourth Edition of LODI RULES is currently being translated into Spanish. For the Spanish version of the Third Edition, click HERE.

The goal of the Fourth Edition is to improve the LODI RULES sustainability certification program based upon new knowledge that’s been gained over the last decade. By improving the program over time, the certification continues to be relevant and progressive, and stays at the forefront of sustainability innovation. Too many changes too often can be confusing to growers and the community. Since we are transitioning to a new pesticide risk model, this was the prime time to add in a small number of new standards and revise existing standards. For a PDF of the Fourth Edition with changes noted, click HERE. New standards address topics such as sustainability communication, beneficials, invasive species, erosion, mealybugs, and viruses.

As a reminder, each LODI RULES standard must:

1. Address at least one of the three aspects of sustainability (environment, people, business).
2. Be measurable/auditable.
3. Be economically feasible to implement.
4. Be based in science (not a trend).

Implement all mandatory “Fail Chapter” Standards. For a list of “Fail Chapter” Standards, click HERE.


LODI RULES Management Plans & Audit Prep Checklist

The LODI RULES Program involves creating and updating management plans such as a human resources management plan, an ecosystem management plan, and a nutrient management plan. For a list of management plans (including examples of several plans and tips on how to write them) along with an Audit Prep Checklist, please check out Tab 10 in your LODI RULES binder or click HERE. You can also view webinars on how to write many of the plans HERE.


Pesticide Risk Model: PEAS 2.0

LODI RULES uses a unique science-backed risk tool called PEAS 2.0, based upon the original PEAS (Pesticide Environmental Assessment System) and the IPM Institute’s Pesticide Risk Tool to quantify the environmental and human impact of the active ingredients of pesticides available for use on winegrapes. PEAS 2.0 was developed specifically for LODI RULES with the expert help of world-renowned pesticide risk scientists, integrative biologists, plant pathologists, viticulturists, growers, environmentalists, and pest control specialists.

PEAS 2.0 generates numeric scores for a total of 15 risk indices across the following categories:

▪ Risks to workers and consumers
▪ Acute risks to aquatic invertebrates, algae and fish
▪ Risks to earthworms
▪ Small mammal risk
▪ Acute and reproductive risks to birds
▪ Risks to bees and beneficial insects (pest natural enemies)

A grower’s LODI RULES PEAS 2.0 Risk Score is calculated for the certification year, which runs from post-harvest of the previous year through harvest of the current year. It is calculated for each material applied to a vineyard block on a per-acre basis, and the summed score for all applied materials cannot exceed the threshold of 225 points as required to pass certification in LODI RULES Standard 6.33. PEAS Reports must be submitted to the auditor every year by October 31.

To calculate your PEAS 2.0 Risk Score, you will need to use:

1. LODI RULES PEAS 2.0 Calculation Instructions and Risk Table (use Control + F to search this document)
2. LODI RULES PEAS 2.0 Auto-Calculating Report Template, available by logging in to your Online Self-Assessment
3. LODI RULES PEAS 2.0 Field Guide showing breakdown of risk

LODI RULES Online Self-Assessment Website

In addition to the LODI RULES for Sustainable Winegrowing Certification Standards binder, Protected Harvest’s online self-assessment website is an essential tool for LODI RULES growers. The assessment site allows growers to submit their farming practices, which are reviewed by the auditor. All assessments must be completed using this online system – no paper assessments are accepted. Log-in information is available from Protected Harvest after certification applications are submitted.

The Online Self-Assessment User Guide provides detailed step-by-step instructions for navigating the online self-assessment website. The user guide is included in the LODI RULES for Sustainable Winegrowing Certification Standards binder in Tab 9.


LODI RULES Grower Marketing Tools

In 2019, we responded to requests from growers by introducing a Marketing Tab to the LODI RULES binders. Since then, we’ve continued to add tools to help our LODI RULES certified growers market their sustainable grapes. Here are some materials to help you share your sustainability message with the world:


Vineyard and Winery Signs

Permanent signs are a wonderful way to communicate your commitment to sustainable agriculture. Signs are available for purchase to all growers participating in the LODI RULES program (certificate required) and all wineries using the LODI RULES seal on wine labels. The signs can be installed in any high-visibility locations. Two sign options are available: a horizontal orientation and a vertical orientation. The horizontal option (24″ x 32″) is designed to be read from a passing car, so it is well-suited for road-side vineyards. The vertical option (32″ x 24″) is designed for easy installation and its geometry is appropriate for tight spaces such as winery parking lots or seating areas. However, feel free to choose either sign for any application. Signs will be customizable with your vineyard or winery name. Place your orders with Robyn at Gary’s Signs. Robyn is happy to communicate via email ( or by telephone at 209.369.8592 (7:30am – 5pm). Signs may bear the LODI RULES, CALIFORNIA RULES, or CERTIFIED GREEN seal.
