Biosphera launches biopesticide Powerbac Inductor

Brazilian biological input company Biosphera Agro Solutions has announced the exclusive launch of the fungicide and bactericide Powerbac Inductor, formulated with Bacillus velezensis BV02, to AgroPages.

According to the developers, this microbiological product has a broad spectrum of control and is recommended for combating pathogens that attack the aerial parts of plants, such as anthracnose, leaf spots, and powdery mildew.

"With the advancement in the development and commercialization of bio-inputs in Brazil, the use of biological products has become an important strategy in the management of plant diseases, including foliar diseases," Biosphera stated.

Among the microorganisms used today in this biocontrol are those from the genera Trichoderma and Bacillus, which are the most studied. The action mechanisms of these agents include competition for niches and nutrients, antibiosis or antagonistic interaction through the production of compounds and secondary metabolites, and the induction of resistance.

According to agronomist Isabela Gato, who works in the company's Research, Development and Innovation area, the solution stimulates the natural resistance of plants. "With proven benefits in managing key diseases, this product contributes to more sustainable and profitable agricultural practices, preserving biodiversity, providing greater safety for humans and animals, and ensuring the productivity of crops across different cultures," she said.

The microorganism B. velezensis acts through biochemical signals and activation of resistance genes, generating immune responses against phytopathogens and enhancing the plant's defense against future infections.

"Therefore, its use as a biological agent in foliar disease management represents a promising strategy for farmers seeking sustainable alternatives that are less dependent on agrochemicals," the specialist highlighted.

Its effect on resistance induction becomes a valuable tool for combating aerial pathogens, such as anthracnose, leaf spots, powdery mildew, among others, thereby improving plant health.

How Resistance Induction Works

Resistance induction can occur through different pathways, two of which are linked to the direct production of proteins related to the onset and progression of the disease, known as pathogenesis.

"In one pathway, protein production occurs in response to pathogen attacks, the organisms causing the diseases, while in the other, the presence of proteins is a consequence of injuries or pathogenesis that induce plant necrosis," Isabela explained.

The pathogen-induced pathway is related to salicylic acid as a signaling molecule, while the injury pathway is associated with jasmonic acid and ethylene.
