For decades, much of the innovation in crop protection has been associated with the discovery of new active ingredients. But in 2026, another technology race is gaining momentum: getting those molecules to the target more effectively, keeping them stable and extracting greater performance from every application. Our review of international developments, technical information, market trends and regulatory guidance indicates that formulations and adjuvants are moving from a supporting role toward becoming a strategic part of crop input performance.

The reason begins with a fact that is easy to overlook when looking at a product label: an active ingredient never works alone. Before controlling a weed, disease or insect, it must remain stable during storage and transportation, mix properly with water, move through application equipment, form appropriate droplets, reach the target and, depending on the product, adhere to or penetrate plant tissue. Formulation technology influences much of that journey and can ultimately affect how much of the potential contained in a jug becomes actual agronomic performance.

The Active Ingredient Isn't Enough: Formulation Is Becoming the Next Crop Protection Battleground

International standards reinforce that distinction. FAO and WHO pesticide specifications consider more than the identity of an active ingredient. Specifications can also address physical and chemical properties and storage stability, among other quality parameters. In practical terms, the molecule remains fundamental, but the commercial product reaching a farm is a considerably more complex technological system.

The Invisible Battle: Getting More of the Application to the Target

Our analysis of formulation technologies advancing across different markets shows that performance is built through several stages. A product first needs stability inside the container. It must then disperse or emulsify correctly when mixed with water, move through pumps, filters and nozzles, and finally produce droplets with suitable characteristics. Those droplets still have to travel toward the target, deposit on it and remain there long enough for the treatment to perform as intended.

FAO's registration guidance illustrates how deeply formulation is embedded in the technical identity of a pesticide. Information requirements for formulated products can include the active ingredients, formulants, function of those formulants and manufacturing or formulation information. Formulation type - such as an emulsifiable concentrate, wettable powder or soluble concentrate - is therefore not simply a packaging distinction. It is part of how the finished product is characterized and evaluated.

What Happens Between the Container and the Crop?

Adjuvants provide one of the clearest examples of this largely invisible engineering. The U.S. Environmental Protection Agency recognizes a broad range of functions associated with inert ingredients and spray adjuvant technologies, including surfactant, dispersing, emulsifying and other functions that can influence how a pesticide product or spray mixture behaves.

This has direct consequences for application technology. EPA guidance addressing spray-drift mitigation recognizes that droplet size and application practices can influence drift potential and that certain drift-reduction approaches can alter the droplet spectrum. That does not mean adding an adjuvant automatically improves an application. Performance depends on the chemistry, use rate, equipment, nozzle, carrier volume and environmental conditions. But it underscores a central point: what happens after the product leaves the nozzle can be almost as important as what was inside the container.

Our review identified commercial and experimental technologies designed specifically around those variables. In tests involving adjuvants for aerial application, comparative images show changes in droplet-size distribution, fewer fine droplets, altered viscoelastic behavior and improved deposition. These are developer-generated results and should not be generalized to every application, but they illustrate where formulation R&D is heading: not simply determining what molecule should be sprayed, but engineering how efficiently it reaches its intended target.

What Formulation Technology Can Change

There is an important caveat. Bigger droplets are not automatically better droplets. Increasing droplet size can reduce drift potential, but an excessive shift toward coarse droplets may compromise coverage for applications where surface coverage is critical. Formulation and application science therefore involve balancing multiple variables - drift, evaporation, deposition, coverage, retention and biological performance - rather than optimizing one parameter in isolation.

Drones, Biologicals and AI Are Opening a New Technology Race

Precision agriculture is raising the stakes. A formulation developed around conventional ground spraying may face very different conditions when applied by a drone at substantially lower carrier volumes. Higher concentrations in the spray solution can alter interactions among components, while evaporation, droplet size, drift and deposition become increasingly important. The growth of unmanned aerial application is therefore pushing developers to consider formulation, adjuvant and application technology as parts of the same system.

Among the technologies examined in our review are experimental platforms designed to study the complete journey of spray droplets, from formation to transport and deposition, using wind tunnels and equipment intended to simulate aerial applications. New adjuvants are also being developed specifically for low-volume spraying. These technologies still require validation across crops, environments and commercial field conditions, but they reveal where a portion of industry R&D investment is moving.

For U.S. agriculture, spray drift adds an important regulatory dimension. The EPA's pesticide mitigation guidance includes application measures involving droplet size, boom height and drift-reduction technologies depending on the pesticide and use pattern. That means formulation and application technology increasingly intersect not only with efficacy, but also with stewardship, label compliance and the ability to keep applications on target.

Biological crop protection adds another layer of complexity. When the component of interest is a microorganism or another biologically derived active, developers may need to preserve stability - and, where relevant, viability - throughout storage, transportation, tank preparation and application. FAO and WHO now maintain specific specification guidance for microbial pesticides, illustrating how the expansion of biological crop protection is creating additional formulation challenges rather than making formulation science less important.

Technologies Driving the Next Shift

Artificial intelligence is beginning to move into the formulation laboratory as well. Technologies reviewed by AgroLatam include platforms designed to automate sample preparation and evaluation while using computational models to connect composition, particle size, interfacial behavior and expected performance. One developer projects that its system could increase formulation R&D efficiency by two to four times. That figure is a company estimate rather than independently validated performance, but the direction is noteworthy: using AI to narrow potential combinations before committing resources to extensive physical testing.

This shift could eventually change how growers and advisers think about the economics of crop inputs. If formulation technology can improve deposition, stability, coverage or penetration, the value of a product cannot be judged exclusively by how many ounces or pounds of active ingredient are inside the container. Nor does better formulation automatically mean that growers should reduce labeled rates. Applications must continue to follow pesticide labels and agronomic recommendations. The larger issue is how effectively the complete system converts a legal, labeled application into the intended field result.

That question is particularly relevant across the United States, where growers are managing high input costs, herbicide resistance, tighter application requirements and increasingly sophisticated equipment. Water quality, temperature, humidity, wind, crop canopy, nozzle selection and carrier volume can all influence application performance. A formulation that performs well under one set of conditions cannot simply be assumed to behave identically across every crop, state or application system.

The active ingredient will remain at the heart of herbicides, fungicides, insecticides and many biological crop protection products. But our review indicates that an increasing share of innovation is taking place around the technology responsible for delivering that active ingredient. The next competitive race in crop protection could therefore unfold on two fronts: discovering better molecules and designing better systems to keep those molecules stable, move them through increasingly precise application equipment and deliver them where they need to work.

For farmers, the question is ultimately less about formulation chemistry than farm economics: How much of what you buy and apply actually goes to work on the crop? At a time when every acre carries significant input, equipment and labor costs, formulations are moving out of the background. They may become one of the technologies that determine how much performance agriculture can extract from every application.
