Bacteria is the basis for a pesticide developed by Vittia that combats powdery mildew

Bio-Imune is a biological fungicide with high formulation technology, containing three different compounds that degrade the structure of the fungus that causes powdery mildew. In it, fengycin, iturin and surfactin come together with an exclusive strain of Bacillus velezensis BV02 to provide a high residual in the leaf, being compatible with several products. The product is also considered multisite, that is, it acts on several metabolic points of the fungus at the same time, which reduces the chance of it developing resistance. Beneficial bacteria Bacillus velezensis is a spore-forming soil bacterium widely used in sustainable agriculture as a biostimulant and in the biological control of plant diseases. It fights fungus and bad bacteria and helps roots grow strong. It is capable of fighting diseases, as it produces substances that kill harmful fungi and bacteria, but it also protects the soil, creating a barrier at the roots against pests such as nematodes. An additional effect is that it produces hormones that make the plant develop more vigorously.
