With more fungicide active ingredients coming off patent in the coming years, you’ll soon have even more crop protection products to consider. Typically, patents expire 20 years after patent filing. That opens the door for other manufacturers to produce generic formulations that may be more affordable than the name-brand equivalent.
How do those generic products stack up?
Let’s look deeper at the main differences between generic and branded fungicides. In this post, we’ll answer:
Pros | Cons |
Lower price | Limited performance data |
No rebate programs, extra paperwork to manage | May have less effective inert ingredients |
More options/market competition | Generally limited field support |
Often equivalent performance as branded fungicides |
Pros | Cons |
Proven performance with data validation | Higher price |
Backed by field support | May provide less value than generic products (performance vs. cost) |
May include more effective inert ingredients | May need to submit rebate paperwork to reduce product price |
Yes, generic fungicides are subject to the same rigorous registration process as the original branded products. This means that all the guidelines, restrictions, and reviews are comparable. From a regulatory standpoint, generic fungicides must contain the same active ingredient components as their branded counterparts to be registered by the government regulator.
One key advantage of generic fungicides is their potential to deliver similar results to their name-brand equivalents at a fraction of the cost. The generic version of a name-brand product contains the same active ingredient as the name-brand version, making the fungicidal activity very similar.
However, differences in the inert ingredients or product formulation, including the presence or absence of surfactants and adjuvants, may affect product penetration and plant uptake.
At FBN, we invest millions of dollars each year to conduct comprehensive analyses of our generic products to ensure they perform as well as or better than the branded product. Product evaluations include:
Laboratory screening (stability studies, physico-chemical testing like viscosity, pH, density, etc.)
Formulation testing (e.g., emulsion stability, persistent foaming, pourability, suspensibility, etc.)
Field trials comparing an FBN generic fungicide to its branded counterpart

There are several reasons generic fungicides may be more affordable than brand-name products, including:
Minimal investment is needed to register a generic fungicide because most of the heavy lifting has already been done by the original product manufacturer.
Many name-brand fungicides are manufactured by multinational companies that invest millions of dollars annually in the people, facilities, and research and development (R&D) required to bring new products to market. To counter those investments, they must extract the highest profit margin possible from their fungicide product.
Generic product producers can piggyback off the work that’s already been done to register these products to minimize costs.
Most generic fungicides don’t require extensive marketing because the name-brand product has been marketed and established among the agricultural community for decades. Branded products often charge a brand premium, extracting extra value for the recognition of their company and their product.
As previously mentioned, some inert ingredients in a generic product may differ from those in the brand-name product. Often, those inert raw ingredients may be less expensive, reducing the manufacturing cost of the generic product.
Generic fungicide producers, including FBN, can cut out the intermediaries in the value chain, passing those savings on to farmers. For example, in early 2024, we announced the opening of our new blending facility within an existing FBN fulfillment center in Mississippi that allows us to offer a reliable supply of fairly priced ag chem and respond to product demand surges efficiently.
Generic manufacturers typically do not have rebate programs and the associated administrative costs. Instead, they offer a lower up-front product cost, which is often more convenient for buyers.

The short answer is no. While generic fungicides typically have the same active ingredients as the brand-name equivalent, there may be slight formulation differences.
Solvents, stabilizers, emulsifiers, surfactants, and other additives are part of a fungicide formulation but don’t have fungicidal activity as an active ingredient does. Instead, inert ingredients in the formulation may help enhance the spray application by:
Reducing product tie-up
Enhancing product uptake
Increasing dilution in water
Generic fungicides may have slightly different inert ingredients compared to brand-name products; however, product performance differences should be minimal unless one of the inert ingredients is missing.
While the active ingredient of a generic product must be the same as that of a name-brand equivalent, it may not be in the same concentration or have the same chemical structure. So, even though the chemical formula of two products is the same, the atoms in their molecular makeup may be positioned differently, leading to differences in biological activity.
For example, as M. Singh, W. Mersie, and R. H. Brlansky explored in “Phytotoxicity of the Fungicide Metalaxyl and Its Optical Isomers” for Plant Disease, the active ingredient of the systemic fungicide metalaxyl contains several chemical isomers, some of which are phytotoxic to young citrus trees.

Generic fungicides can offer high-quality crop protection while reducing disease management input costs. To evaluate whether they are a good fit for your particular circumstance, compare their price, safety, and relative performance to the name-brand alternative. If performance data for the fungicide you’re interested in is unavailable, consider running a small in-field trial using name-brand and generic fungicides side-by-side to compare performance and mitigate risk.
As you evaluate generic products, compare their labels to the name-brand equivalents. Questions to ask as you compare the labels include:
Are the active ingredient concentrations the same?
Are the inert ingredients significantly different?
If so, do you anticipate performance differences?
Is the generic product labeled for the crops and application types you’re expecting to use it for?
