In 2026, biologicals have secured a more defined position in crop management programs across Latin America, particularly in seed treatment, nematode management and preventive strategies against pests and diseases. Their expansion comes as the number of available products and market competition continues to increase, along with expectations for efficacy and consistency. The key change is agronomic: biologicals are no longer viewed simply as experimental technologies, yet they have not broadly replaced conventional crop protection products. Their strongest value is increasingly emerging as part of integrated management programs.

That shift is particularly visible in Brazil and Argentina, where large-scale row-crop production provides a significant testing ground for new technologies. Technical information reviewed by AgroLatam points to seed treatment and nematode management as two areas where biologicals have moved most clearly from emerging alternatives to established tools. Applications targeting insects, soilborne and foliar diseases are also expanding. The question is therefore becoming less about whether biologicals work and more about where they work, under what conditions and how they can be combined with other technologies to improve predictability and return per acre.

Biologicals

Biologicals Gain Ground in Latin America, but Where Do They Really Fit in the Grower's Toolbox?

Seed Treatment and Nematodes: Where Biologicals Have Established a Foothold

Seed treatment has become one of the most established entry points for biological technologies because it can place beneficial microorganisms close to the developing root system from the beginning of the crop cycle. Argentina also has decades of experience with inoculants, while Brazil's growing use of bionematicides illustrates how far biological technologies can advance against specific agronomic problems. Sector data reviewed for this report indicate that biopesticides may already represent approximately 75% of the nematode-management market, suggesting that biologicals have moved well beyond a peripheral role in this segment.

Where Biologicals Are Gaining Ground

Expansion into insect management is another sign of market maturity. In soybeans, corn and cotton, microbial and viral technologies are gaining ground against specific pests, while biofungicides are finding a role against soilborne and foliar diseases. Among the technologies advancing are products based on nucleopolyhedroviruses (NPVs), which are moving beyond niche applications in certain management programs. The distinction is important: not every biological segment is developing at the same pace, and not every agronomic challenge allows the same degree of substitution for conventional crop protection tools.

That is also where one of the limitations behind the biologicals boom becomes apparent. Under severe pest or disease pressure requiring rapid control, conventional crop protection tools continue to occupy positions that can be difficult to replace. Biologicals, however, can introduce different modes of action, strengthen preventive strategies and expand options for resistance management. Technical evidence increasingly challenges the idea of a binary choice between biology and chemistry: the two can perform different functions and operate as complementary components of the same crop protection program.

The Grower's Changing Toolbox

The Next Challenge Is Not More Biologicals - It Is Proving Which Ones Work

Rapid expansion is creating a different challenge. The market analyzed includes more than 150 companies and roughly 600 products, increasing both competition and the number of choices available to growers. But a larger product portfolio does not guarantee uniform performance. Microorganisms belonging to the same species can behave differently depending on the strain, formulation, concentration, manufacturing process and quality controls. For growers and crop advisers, that distinction is critical. The next phase of biologicals will be determined less by how many products reach the market and more by how consistently they perform under commercial field conditions.

The technology behind a biological product also explains why quality will become a higher barrier to entry. Technical information reviewed by AgroLatam shows development programs that can require around five years, teams of more than 50 researchers and the evaluation of roughly 800 microorganisms to identify a candidate capable of advancing toward field use. Fermentation, formulation, stability, industrial scalability and field validation add further complexity. Competition is therefore moving beyond access to a microorganism toward the ability to transform it into a stable, reproducible and economically viable agricultural tool.

The Scale Behind Biological Innovation

Regulation adds another layer of complexity because not all biological products are alike. Microbial products based on bacteria, fungi or viruses, as well as botanical extracts, pheromones, semiochemicals and biochemical substances, can require different regulatory approaches. Information reviewed on Mexico, for example, shows that proper classification of an active ingredient can affect study requirements and the registration pathway. This highlights a broader regional issue: market growth will depend not only on innovation, but also on product quality, scientific characterization and regulatory frameworks capable of keeping pace with emerging technologies.

For growers, the economics are changing as well. The relevant question is no longer simply the price of a gallon or pound of product, but what it delivers per acre and how predictable that result is. This is particularly important across Latin America, where soybeans, corn, cotton and other crops can face intense pest and disease pressure. Additional modes of action may support resistance management while allowing genetics, conventional crop protection products, biologicals and digital agriculture to work within the same production system. Integration, rather than wholesale substitution, is increasingly becoming the defining principle.

That is why saying biologicals will simply replace conventional crop protection products is as misleading as continuing to treat them as marginal add-ons. There are already agronomic positions where biologicals are core tools and others where they can compete directly with conventional technologies, while certain situations still require fast and consistent conventional responses. That boundary will continue to move as strains, formulations, manufacturing and application systems improve. For growers, the decision will ultimately be practical: the technologies that remain in the toolbox will be those that consistently deliver efficacy, reliability and return per acre.
