Red Sun Debuts Two Microbial Pesticides at China’s ACE2026
02 November 2026, Shanghai, CN: Chinese agrochemical producer Red Sun Co., Ltd. introduced two new microbial crop protection products at the 26th National Pesticide Exchange Conference and International Agrochemical Products Exhibition, known as ACE2026, held October 14 to 16 at the Shanghai World Expo Exhibition and Convention Center. The event drew more than 1,000 exhibiting companies from over 120 countries and regions and more than 100,000 professional visitors, and Red Sun used it as the launch platform for the two formulations, which it is positioning for overseas markets in Southeast Asia, South America and Africa.
The first product is an upgraded Bacillus thuringiensis, or Bt, suspension concentrate built on a selectively bred, high-toxicity bacterial strain. Red Sun manufactures it through high-density submerged fermentation combined with a spore-protection process, which the company says lifts effective spore content more than 40 percent above the industry standard. The formulation is aimed at more than ten major pest categories, including caterpillars and beetles from the Lepidoptera and Coleoptera orders, across rice, vegetable and fruit crops. Bt-based biopesticides work by producing proteins that are toxic to the digestive systems of targeted insects when ingested, while leaving most beneficial organisms unaffected, which has made the category a mainstay of biological pest control programs worldwide.
Naturally derived antimicrobial compound
The second launch, epsilon-polylysine, is a naturally derived, bio-based compound that Red Sun describes as China’s first industrialized preparation of its kind. The substance breaks down into essential amino acids and has shown activity against a broad range of microorganisms, including Gram-positive and Gram-negative bacteria, along with yeasts and molds such as E. coli and Salmonella strains, according to the company. Red Sun is marketing epsilon-polylysine for field-level disease management as well as post-harvest preservation of crops, a dual use case that distinguishes it from conventional fungicides confined to pre-harvest application.
Alongside the two new products, Red Sun’s booth at ACE2026 also featured established lines including glufosinate-ammonium, chlorantraniliprole and diquat dichloride, and the company demonstrated an AI-powered cross-border pesticide service platform designed to support pest and disease monitoring, precision application and product traceability for international customers.
Buyers, distributors and industry representatives from Southeast Asia, South America, Africa and other regions visited the Red Sun stand during the three-day event, the company said. Discussions covered regional registration requirements and the possibility of joint registration arrangements, along with cooperation on bulk procurement, regional brand representation and further product development. Red Sun characterized these as prospective partnerships rather than confirmed commercial agreements, and no product registrations tied to the new launches have been reported in the markets under discussion.
The dual launch reflects a broader shift among Chinese crop protection manufacturers toward biological and bio-based products as export markets tighten rules around chemical residues and as domestic authorities encourage lower-toxicity formulations. Microbial pesticides such as Bt concentrates have gained ground in rice and vegetable production across Asia, where resistance to some synthetic insecticides has built up over repeated seasons, while bio-based preservatives like epsilon-polylysine are drawing interest from supply chains seeking alternatives to synthetic fungicide residues on fresh produce bound for export.
Positioning for export growth
Red Sun’s emphasis on overseas buyers at ACE2026 points to the growing importance of export markets for Chinese biological pesticide makers, which have expanded production capacity for microbial and bio-based actives in recent years even as the domestic market for conventional synthetic pesticides has faced overcapacity and pricing pressure. By pairing an upgraded Bt concentrate, a category already familiar to regulators and growers in Southeast Asia, South America and Africa, with a newer antimicrobial compound in epsilon-polylysine, the company is betting that a mix of established and novel biological chemistry will appeal to buyers looking to diversify away from synthetic residue-sensitive products.
The spore-protection fermentation process Red Sun uses for its Bt concentrate is designed to improve the shelf stability of the live bacterial spores, a persistent technical challenge for microbial pesticide manufacturers, since spore viability can degrade during storage and transport, particularly in the humid or high-temperature conditions common across many of the export markets the company is targeting. A higher effective spore count per unit of product, if borne out in field use, would let growers apply less material for the same level of pest suppression compared with standard-grade Bt formulations.
For epsilon-polylysine, Red Sun’s framing of the compound for both field disease management and post-harvest preservation reflects a wider industry interest in multi-use biological actives that can serve both the production and post-harvest segments of a single supply chain, reducing the number of distinct inputs a grower or packer needs to source and manage. The company did not disclose production capacity, pricing or target registration timelines for either new product in the markets it is courting.
