04 November 2026, Porto Alegre, BR: Sinon do Brasil has launched Sinsmart CL3, a microbial biofungicide based on a strain of the bacterium Bacillus amyloliquefaciens, for disease management in Brazil’s soybean crop. The product, registered in Brazil as a microbiological crop protection product after passing efficacy and safety assessments from the country’s regulatory authorities, gives soybean growers a biological option to rotate into spray programs that currently rely heavily on conventional fungicides.
The CL3 strain at the center of the product is commercialized exclusively by Sinon under a technology transfer arrangement with a research institution. Company production relies on proprietary fermentation facilities, industrial scale manufacturing and what Sinon describes as a ten stage quality control system, intended to keep the microbial formulation, a suspension concentrate, consistent across batches. The company states the formulation carries a shelf life of at least three years under ambient storage conditions, a property that matters for a biological product moving through Brazil’s long and often humid agricultural supply chains.
Three ways the product controls disease
Sinsmart CL3 works through three mechanisms, according to the company. The Bacillus strain competes with fungal pathogens for space on leaf surfaces, limiting the area available for disease organisms to establish themselves. It also produces antifungal lipopeptides capable of damaging pathogen cell structures directly. The third mechanism is induced systemic resistance, in which the bacterium triggers the soybean plant’s own defense responses rather than attacking the pathogen itself.
In company reported trial results from the 2025 to 2026 growing season, Sinon said Sinsmart CL3 delivered strong control of Asian soybean rust, caused by the fungus Phakopsora pachyrhizi, when applied between the V3 and V8 growth stages, along with control of powdery mildew and several leaf spot diseases, and a measurable yield gain over untreated plots at harvest. The company has not published the underlying trial data or methodology, and it cautioned on its own that results from its trials may not replicate uniformly across Brazil’s varied growing regions. Sinon said early season application also appeared to reduce phytotoxic stress associated with broader crop protection programs.
A Brazilian regulatory listing for a product under the same company name and active strain, described as Sinsmart CEP CL3 and also sold under the brand Wanda, carries registration number 29623 and lists a broad range of target diseases beyond soybean rust, including grey mould, anthracnose and white mold, suggesting Sinon has pursued a wide label for the active ingredient across multiple crops and pathogens.
Already active in three overseas markets
Brazil is the newest market for the CL3 strain, which Sinon says growers already use in Thailand, Vietnam and Ukraine. The company is positioning the Brazilian launch as part of a broader push to diversify soybean disease management programs at a time when fungicide resistance is a growing concern among Brazilian growers and agronomists. Sinon has outlined potential expansion of the same active ingredient into coffee, citrus, strawberries, grapes, avocados, solanaceous crops, cucurbits, asteraceous crops and brassicas, though it says adoption in each case will depend on how well the biofungicide fits existing spray programs, performs consistently across different fields and proves its economic value to growers relative to conventional alternatives.
Sinon frames Sinsmart CL3 as a complement to, rather than a replacement for, conventional chemical fungicides in integrated disease management programs. That positioning reflects a broader pattern across Brazil’s biologicals market, where microbial and biochemical products are increasingly sold as rotation partners that extend the useful life of synthetic chemistry by reducing the selection pressure that drives resistance, rather than as standalone substitutes for it.
Asian soybean rust remains one of the most economically damaging diseases in Brazilian soybean production, capable of cutting yields sharply when conditions favor its spread during the wet months of the growing season. Growers typically manage it with multiple fungicide applications timed around the crop’s reproductive stages, a practice that has contributed to resistance development in some fungicide classes used widely across Brazil’s soybean belt. A biological product with a different mode of action gives agronomists another option to break up spray sequences built entirely around synthetic chemistry.
Sinon’s entry into Brazil’s biofungicide segment also reflects the pace at which international crop protection companies are expanding their biological portfolios in the country, where demand for alternatives to conventional pesticides has grown alongside tighter scrutiny of residue levels in export commodities. Brazil’s soybean crop, the largest in the world by planted area, remains the primary commercial proving ground for new biological products seeking a foothold in Latin America before expanding into neighboring markets such as Argentina and Paraguay.
