Napa Green is the first sustainable winegrowing certification globally to require the phaseout of Roundup, and ultimately synthetic herbicides. When we looked for a roadmap and resources for going herbicide-free we didn’t find it all in one place, so we created this Weed Management Toolkit to support our Napa Green community and other perennial growers looking to cultivate healthier soils and regenerative farm systems.
Since Napa Green became an independent nonprofit in 2019, our goal has been to set the highest bar for sustainability and climate action in the wine industry. Our next-level Napa Green Vineyard program, launched in 2021, is unique in its whole-systems focus on: Social Justice, Regenerative Ag & Soil Health, Irrigation Efficiency, Forest Health, Climate-smart burning/alternatives, and Pesticides.
While pesticide and herbicide use is just one element of a holistic approach to sustainable winegrowing and climate action leadership, this leadership matters to our families, our communities, and our customers. As a world-renowned winegrowing region, producing the premier agricultural product, we must leverage our powerful leadership platform to galvanize change locally and globally.
Clemens Weed Knife
Pros: Lower soil disturbance, no soil inversion. High ground speed. The frame can also support a ‘twister’ type mower for a pre-knife pass, or a french plow for deeper disturbance. Single- or double-sided.
Cons: Low level of disturbance means weeds can re-sprout depending on timing and soil moisture. Not great with heavy weed cover. Can either be one sided (lower efficency) or, on flat ground, can have a second side, but might require multiple passes.
Sheep
Pros: Ability to manage the entire vineyard floor, even steep, terraced, and tight rows, without fossil fuels. Increased nutrient cycling, as well as soil and vine health.
Cons: Require knowledgeable shepherds to be managed/rotated effectively. Small parcels are inefficient. Damage to vines and infrastructure is possible.
Organic (OMRI) Herbicides
Pros: Helpful as a foliar spray when the soil is too wet to cultivate. Reduces weed competition in unfavorable conditions
Cons: Organic herbicides do not match the effectiveness of synthetic herbicides, but are another tool in the weed management kit. They are ineffective once weeds have fully established root systems and can be expensive.
Note that feedback is assembled from members who have used these tools.
The Napa Green Vineyard certification provides growers a beneficial roadmap for continual improvement. The process lead Dominus Estate to measure our environmental impact and, since we can only change what we measure, has strengthened our methods for interacting with our site's vital resources: soils, water, flora, fauna and people. Ultimately, this certification improves the grower's relationship to the land and deeply informs farming decisions.
Eliminating Roundup and other synthetic herbicides is a significant step towards more just, resilient agricultural communities and local ecosystems. A non-exhaustive list of the benefits: Farmworker health, Soil health, Ecosystem health, Community health, Consumer health, Consumer perception/Market demand, Visibility of Napa Valley and the wine industry.
