Ponastar an active ingredient and is a biological control agent for use on several minor crops to treat a variety of plant diseases and fungal pathogens including gray mold, powdery mildew, early and late blight, bacterial spot, and walnut blight. Ponastar is ubiquitous bacteria commonly found in various ecological niches including soil, water and air which do not have a history of pathogenicity from contact in the environment.
Ponastar is a biological control agent, Microbial Fungicide. The bacterium is prevalent in soils and has been found in a variety of habitats worldwide. Ponastaris known to be antagonistic toward many fungal plant pathogens. This antagonism may be achieved in several ways including nutrient competition, site exclusion, colonization and attachment of the bacteria to the fungal pathogen. In addition, there are reports that these strains helps to induce plants’ natural systemic resistance or systemic acquired resistance (SAR) against bacterial pathogens. These bacteria can stop plant pathogen spores from germinating, disrupt germ tube growth and inhibit attachment of the plant pathogen to the leaf.
