Over the past few years, ag retailers and their grower-customers have increasingly turned to biologicals in their crop fields. These products, oftentimes paired with conventional pest control options, can provide added modes of action to combat insects, weeds, and diseases.<\/p>\n
Coupled with this trend is the need for adjuvants. These products, added to the application mix, can help with efficacy and handling.<\/p>\n
\u201cWe see the adjuvants market for biologicals as early-stage but growing quickly,\u201d says Ganesh Sanganwar, Ph.D., Business Development Manager at Syensqo<\/a>. \u201cWhat is clear is that biological adoption is increasing and expanding beyond high value crops, creating a stronger need for adjuvant technologies that make biological products easier to handle and more consistent in the field. We believe adjuvants will grow with biologicals but also contribute greatly to their larger adoption by enabling them to bridge the performance gap with traditional inputs.\u201d<\/p>\n The numbers seem to back up Sanganwar\u2019s assertion. According to the data, the U.S. biologicals market was estimated to be worth approximately $5 billion in 2025, with a projected compound annual growth rate of between 8% and 13% through 2030. Market watchers credit the rise in regenerative agriculture, carbon programs, and precision agriculture for much of this projected growth, not to mention the increasing popularity of organic farming.<\/p>\n \u201cThe status of the adjuvant market for biologicals is one of opportunity, for both in-can formulation development and tank mix adjuvants, in which shelf life, handling, and performance can be addressed,\u201d says Gregory Lindner, Research Director at Croda Inc.<\/a> \u201cThe adjuvant market specifically for biologicals as a sole treatment is currently small but growing and likely to parallel the growth of the biopesticide market for \u2018organic-certified\u2019 production environments.\u201d<\/p>\n Biologicals have also expanded beyond their initial market segments within the agricultural world. According to Martin Bauer, Head of Global Marketing at Clariant<\/a>, there are two factors at work.<\/p>\n \u201cHistorically, biologicals were confined to niche, high-value fruit and vegetable crops,\u201d says Bauer. \u201cToday, we are seeing a push into row crops as corn, soybeans, and cereals, which is scaling up the total treated acreage.<\/p>\n \u201cWe also see a significant shift in how the market perceives these products,\u201d he continues. \u201cThe understanding that biologicals are highly sensitive active ingredients requiring specialized formulation and delivery is becoming well established. The industry is moving past the era of simply trying to keep a microbe physically stable and alive \u2018in-can.\u2019 The focus today has expanded to optimizing delivery systems and ensuring consistency of field performance under variable environmental conditions. Adjuvants play a key role in this transition, solving the application challenges and ensuring consistent field efficacy, which allows biologicals to deliver reliable, economic returns for the growers.\u201d<\/p>\n Another reason for this recent market growth for biologicals ties back to how these products are being employed by ag retailers and their grower-customers. For several years following their introduction, biologicals were oftentimes positioned as alternatives to conventional crop protection products. But in 2026, they are increasingly viewed as playing a complementary role. Indeed, according to data collected by CropLife\u00ae Magazine<\/em> in its annual Biologicals Survey for 2026<\/a>, 98% of biological use occurs as a supplement with conventional products.<\/p>\n \u201cBiologicals are used primarily as supplements to conventional products rather than stand-alone replacements, reinforcing that most use occurs inside mixed programs where tank-mix compatibility and spray performance become important considerations,\u201d says Priscila Castelani, Ph.D., Global Marketing and Research & Development Director for Crop Solutions at Indovinya<\/a>. \u201cThe segment has changed significantly in three ways: Biological-treated [acres] are expanding quickly; adjuvants have shifted from \u2018optional\u2019 to more performance-critical tools under evolving regulatory and application requirements; and major suppliers are launching or positioning products specifically as bio-compatible tank-mix performance boosters signaling accelerating investment and commercialization.\u201d<\/p>\n Even more recently, adds Castelani, the ongoing implementation of the new Endangered Species Act (ESA)<\/a> rules by the EPA on crop protection products and application have added to the need for adjuvants use when biological products are involved.<\/p>\n \u201cBiological products are not exempt from the regulatory obligations of ESA and must undergo EPA review to ensure they do not jeopardize listed species or critical habitats,\u201d she says. \u201cFor example, microbial biopesticides or RNAi-based products with narrow modes of action may pose limited risks to non-target organisms such as vertebrates, aquatic species, or pollinators. Similarly, products with rapid degradation or low drift and runoff potential are less likely to impact sensitive habitats. As a result, biologicals are often perceived as more \u2018ESA-friendly\u2019 due to their generally lower toxicity, specificity, and environmental persistence.\u201d<\/p>\n As EPA\u2019s ESA implementation focuses on reducing exposure from spray drift, runoff, and erosion, the market is placing more emphasis on \u201cgetting more droplets on target,\u201d says Castelani. This increased pressure to comply with ESA has led to expanded buffer zones, restrictions on the timing of applications as well as drift reduction agents and runoff mitigation actions. Bio-enabled and bio-compatible adjuvants increase the likelihood of biological use that would lower toxic profiles and reduce off-target impacts.<\/p>\n \u201cThis stewardship-driven environment elevates the role of adjuvants that improve deposition and reduce drift, creating a larger \u2018spray-performance platform\u2019 that can also help stabilize biological performance,\u201d she says.<\/p>\n To successfully employ adjuvants and biologicals into their equipment product tanks, custom applicators need to consider several important factors. These include:<\/p>\n \u201cApplicators should consider adjuvants that contain UV protection against the sun\u2019s damaging radiation, humectants to maintain viability, and buffered systems to maintain osmotic balance that protect microbial integrity,\u201d advises Jennifer Bear, Director of Innovation at Exacto, LLC<\/a>. \u201cCertain technology platforms, such as seed treatments and drones, can generate enough energy to damage biologicals. The addition of a compatible adjuvant will preserve the viability of a biological.\u201d<\/p>\n New ag tech could be another driver motivating growth in the biologicals adjuvant sector. As new application technologies such as drones and targeted spraying accelerate specialization, low-volume drone adjuvants focusing on retention, coverage, compatibility in concentrated mixes, and drift reduction will continue to emerge.<\/p>\n \u201cPrecision technology is a perfect fit for biologicals,\u201d says Bear. \u201cBiologicals are usually geared to one pest or one disease. They require correct placement and correct timing. See & Spray systems identify one pest at a time. Variable rate application pairs the dose to the pest pressure. The future of biologicals will lead to a highly technical reliance on adjuvants to optimize performance like what we have experienced with synthetic chemistries.\u201d<\/p>\nBranching Out from Specialty<\/h2>\n
