Agricultural Algaecides Market Report 2026

The agricultural algaecides market size has grown strongly in recent years. It will grow from $3.85 billion in 2025 to $4.16 billion in 2026 at a compound annual growth rate (CAGR) of 8.1%. The growth in the historic period can be attributed to widespread use of copper sulphate in agriculture, increasing frequency of algae blooms, early adoption of synthetic algaecides, rising need for phytoplankton control, demand for water quality maintenance.

The agricultural algaecides market size is expected to see strong growth in the next few years. It will grow to $5.58 billion in 2030 at a compound annual growth rate (CAGR) of 7.6%. The growth in the forecast period can be attributed to shift toward eco-friendly algaecide formulations, growing regulatory limits on chemical discharge, increasing need for large-scale bloom mitigation, advancements in enzymatic and biocontrol algaecides, expansion of precision water treatment. Major trends in the forecast period include rising adoption of copper-and-chelated-based algaecides, increasing shift toward natural and bio-based algaecides, growing use of liquid formulations for faster dissolution, expansion of large-scale algae bloom management programs, development of multi-mode algaecide combinations.

The progressive expansion of the agricultural sector is serving as a catalyst for the upswing in the agricultural algaecides market. Within the agricultural domain, encompassing crop production, livestock breeding, and the harvesting of fish and other animals, the application of algaecides plays a pivotal role in enhancing agricultural output. Algaecides contribute to weed and insect control in areas outside farm structures, nurseries, greenhouses, and other cultivation operations. The augmentation of the agriculture industry correlates directly with an increased utilization of algaecides to optimize production and enhance crop quality. For example, in December 2024, the U.S. Department of Agriculture’s Economic Research Service (ERS), a U.S.-based government agency, reported that agriculture, food, and related industries contributed approximately 5.5% to the U.S. gross domestic product (GDP) in 2023, totaling around $1.537 trillion. Of this, the direct output from farms amounted to $222.3 billion, representing about 0.8% of the U.S. GDP. Consequently, the expansion of the agricultural sector is steering the growth of the agricultural algaecides market.

Leading companies in the agricultural algaecide market are focusing on developing innovative solutions such as bioremediation to improve water quality, reduce chemical usage, and support sustainable algae management in irrigation systems. Bioremediation involves using microorganisms, plants, or natural enzymes to break down and remove pollutants or contaminants from soil, water, or other environments. For example, in September 2023, Arquimea, a Spain-based biotechnology company, introduced BIO100 Anti-Algae, a 100% biodegradable algaecide that combines microbial activity with a sunscreen effect to inhibit photosynthesis and prevent algae growth. This innovation delivers rapid and long-lasting results from the first day of application, promoting sustainable irrigation practices and enhancing overall agricultural productivity.

In July 2023, De Sangosse, a France-based company specializing in crop protection, plant nutrition, and pest control products, acquired AlgaEnergy for an undisclosed amount. This acquisition aims to strengthen De Sangosse's position in the agricultural biosolutions market by utilizing AlgaEnergy's expertise in micro-algae technologies to enhance sustainable farming practices and accelerate global growth in biostimulants, biofertilizers, and biocontrol products. AlgaEnergy is a Spain-based microalgae biotechnology company that includes algaecides among its product offerings.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs are influencing the agricultural algaecides market by raising import costs for raw materials such as copper compounds, chelating agents, and formulation chemicals, leading to higher production and distribution expenses. These impacts are most visible in regions reliant on imported agricultural inputs, including Asia-Pacific, Europe, and Latin America, and particularly affect segments like copper sulphate, chelated copper, and synthetic algaecides. Nevertheless, tariffs are also driving local manufacturing, encouraging domestic sourcing of formulation materials, and supporting regional producers who can offer competitively priced algaecide solutions.

This agricultural algaecide market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenarios of the industry.

Agricultural algaecides are chemical substances used to eradicate and inhibit the growth of algae and cyanobacteria. These substances are employed to mitigate or reduce extensive algal blooms and eliminate phytoplankton. One widely used algaecide is copper sulfate, which is highly soluble in water. When dissolved in water and applied through injection or spraying, copper sulfate induces immediate senescence in algae.

The primary types of agricultural algaecides available on the market include copper sulfate, chelated copper, peroxyacetic acid, hydrogen peroxide, dyes and colorants, and others. Copper sulfate finds applications in both agricultural and non-agricultural settings, serving various purposes such as fungicides, algaecides, root killers, and herbicides. This chemical compound, denoted as CuSO4 and known by names like blue vitriol, the vitriol of copper, and bluestone, operates through different modes of action, including selective and non-selective. The categories of algaecides encompass both synthetic and natural options, available in solid and liquid forms.North America was the largest region in the agricultural algaecides market in 2025. The regions covered in the agricultural algaecides market report are Asia-Pacific, South East Asia, Western Europe, Eastern Europe, North America, South America, Middle East, Africa.
