Brazilian dual-action biological agent Tilsis has been launched, simultaneously solving the two major problems of nematodes and fungal diseases.

Tilsis is developed based on two unique Bacillus strains (Bacillus amyloliquefaciens and Bacillus subtilis) that provide comprehensive protection for plants from root to leaf through a combined action mechanism. Fernando Ferraz Barros, the company's new business director and agronomist, explained: "Its action mechanism involves producing bioactive substances such as lipopeptides and hydrolases, which can destroy the cell membranes of plant nematodes and pathogenic fungi, leading to their death. Additionally, these strains can efficiently form biofilms. The product not only stimulates systemic resistance in plants but also promotes root growth, thereby enhancing the crop's resilience to environmental stress and improving nutrient absorption efficiency."

This dual-action agent can effectively control three major harmful organisms in crops: Pratylenchus brachyurus, Sclerotinia sclerotiorum, and Heterodera glycines. These harmful organisms are widely distributed in major grain-producing areas of Brazil and pose a serious threat to crop yields.

According to the company, field trials across multiple regions and crops have shown that the use of Tilsis can significantly increase crop yields. In soybean fields, compared to the untreated control group, the average yield increased by 10.8%; compared to the standard commercial biological product, the yield was still higher by 4.7%. For legume crops, the yield increase against nematodes was 15.3%, and against Sclerotinia sclerotiorum, it was 16.9%, outperforming traditional reference products. In corn fields with nematodes, the average yield increased by 29% compared to untreated areas, and by 9.8% compared to leading commercial biological products.

In addition to its excellent efficacy, Tilsis also features flexible application methods. The product can be used for seed treatment, furrow application, or foliar spraying, with a shelf life of up to 24 months and no need for refrigeration. Tilsis is highly compatible with the main chemical pesticides used in integrated pest management, allowing farmers to incorporate biological control measures into their traditional farming systems without affecting the efficacy of other inputs—a crucial point since most Brazilian farmers currently use a combination of chemical and biological products in their management strategies.

Superbac emphasizes the sustainable nature of the product, aligning with the global trend of reducing synthetic chemical use and enhancing soil biological balance. The launch of this new product reflects the evolution of bio-product research from single-target, single-mechanism solutions to combined formulations that address multiple harmful organisms through complementary action mechanisms. This evolution requires meticulous screening and matching of microbial strains, compatibility testing, and optimization of formulation processes.
