South America Agricultural Adjuvants Evolve with Precision Spraying and Crop Protection Needs

South America’s agricultural sector is increasingly using adjuvants to improve the performance and efficiency of crop protection applications. Surfactants, crop oils, wetting agents, drift-control products, and compatibility enhancers can help improve spray coverage, droplet retention, penetration, and rain-fastness. Their importance is growing as farmers manage large cultivated areas, complex crop-protection programs, changing weather conditions, and increasingly precise application technologies.

According to a South America agricultural adjuvants industry report, the sector was valued at USD 0.62 billion in 2025 and is projected to reach USD 0.65 billion in 2026 and USD 0.86 billion by 2032, registering a CAGR of 4.84% during 2026–2032. Activator adjuvants account for approximately 76% of revenue in 2026, while liquid formulations represent around 88%. Brazil leads the regional sector with approximately 49% of revenue.

Large-Scale Farming Supports Adjuvant Demand

South America’s extensive agricultural production provides a strong foundation for adjuvant adoption. Soybean, corn, sugarcane, cotton, and other commercial crops frequently require repeated herbicide, fungicide, and insecticide applications. In these programs, adjuvants can help optimize how crop protection products behave during spraying and improve consistency across large fields.

Brazil cultivated approximately 81.8 million hectares of grains during the 2024/25 season, according to the National Supply Company. Such extensive cultivated acreage creates recurring requirements for efficient crop-protection applications, particularly where growers operate within narrow spraying windows.

The Food and Agriculture Organization emphasizes integrated and sustainable crop protection, including improved input-use efficiency and practices that reduce environmental impacts. Adjuvants can support this broader objective when they are selected and applied appropriately within integrated crop-management programs.

Activator Adjuvants Hold the Leading Position

Activator adjuvants account for approximately 76% of the South America sector in 2026. These products are designed to directly improve the performance of crop protection formulations by influencing characteristics such as spreading, wetting, retention, and penetration.

Surfactants and oil-based adjuvants are particularly relevant to herbicide applications across soybean, corn, sugarcane, and other major crops. Their widespread use is connected with the scale of crop protection programs in Brazil and Argentina, where multiple applications can be required throughout the growing season.

The growing complexity of tank mixes is also creating demand for compatibility-enhancing products. As farmers combine multiple active ingredients, formulation compatibility and spray quality become increasingly important considerations.

Liquid Formulations Dominate Application Practices

Liquid formulations represent approximately 88% of the regional sector in 2026. Their leading position reflects their ease of handling, rapid tank mixing, and compatibility with conventional spraying equipment and newer precision-application systems.

Liquid adjuvants can be incorporated into spray solutions with relatively straightforward dosing, which is important for commercial farms managing large areas. Their compatibility with boom sprayers and agricultural drones is creating additional opportunities as application technologies evolve.

The shift toward precision agriculture is also increasing attention toward products designed for specific spray conditions. Low-drift, deposition-enhancing, and penetrant formulations can become more relevant where application volumes, droplet sizes, and environmental conditions vary.

Drone Spraying Creates New Product Requirements

Agricultural drones are becoming an emerging influence on the adjuvant landscape. Drone-based spraying generally uses lower application volumes than conventional ground equipment, making droplet behavior, evaporation control, deposition, and drift management more important.

Brazil’s Ministry of Agriculture and Livestock has developed regulatory provisions for the application of pesticides, fertilizers, and adjuvants using remotely piloted aircraft. The Ministry of Agriculture and Livestock provides regulatory and technical information concerning agricultural inputs and crop-protection products.

As drone adoption expands, adjuvant formulations may increasingly be designed around ultra-low-volume spraying conditions rather than simply adapted from conventional application systems.

Herbicide Resistance Encourages More Advanced Programs

Glyphosate-resistant weeds are creating additional pressure for more sophisticated herbicide programs across South America. As growers introduce multiple modes of action and tank mixtures, adjuvants can play a supporting role in improving spray coverage, uptake, and compatibility.

Resistance management requires more than changing formulations. Crop rotation, integrated weed management, appropriate application timing, and diversified modes of action are also important. The FAO guidance on sustainable crop production emphasizes integrated pest and weed management as components of sustainable agricultural systems.

This environment is creating demand for adjuvants that can support more complex application programs while maintaining reliable spray performance.

Brazil Remains the Regional Center

Brazil accounts for approximately 49% of South America’s agricultural adjuvants sector in 2026. Its position reflects the country’s extensive commercial farming base, large soybean and corn production, multiple crop cycles, and high use of crop protection products.

Mato Grosso is particularly important because intensive soybean and second-crop corn production can require repeated applications across the growing calendar. This creates recurring demand for surfactants, oils, compatibility agents, and drift-control products.

Brazil’s agricultural policy and financing environment also supports investment in crop inputs. The Ministry of Agriculture and Livestock’s agricultural credit information provides information on government-supported financing programs that influence farm investment decisions.

Bio-Based Adjuvants Gain Attention

Environmental considerations and changing export requirements are encouraging interest in bio-based and low-residue adjuvants. Export-oriented growers may need to consider residue standards in destination markets, creating demand for formulations that can complement lower-residue crop-protection programs.

Bio-based products can also support the broader movement toward biological crop protection. However, their commercial adoption depends on formulation stability, field performance, compatibility, cost, and regulatory acceptance.

Adjuvants Move Toward More Precise Crop Protection

South America’s agricultural adjuvants sector is being shaped by large-scale farming, repeated crop-protection applications, herbicide resistance, drone spraying, precision agriculture, and growing interest in sustainable inputs. Activator products and liquid formulations currently dominate, while Brazil remains the leading regional market.

Future development is likely to focus on multifunctional formulations, improved tank-mix compatibility, drift reduction, low-volume spraying, and bio-based technologies. As agricultural operations become increasingly data-driven and application methods more precise, adjuvants are moving from supplementary spray additives toward more specialized components of crop-protection programs.
