Will vinegar kill nostoc?

Yes, vinegar can kill nostoc. Vinegar, particularly in higher concentrations, is an effective natural method for eliminating nostoc. It works by lowering the pH of the surface where it is applied, disrupting the cellular structure of the cyanobacteria and causing it to die. A diluted vinegar solution (about 1 part vinegar to 3 parts water) can be applied directly to nostoc growth. However, it is important to be cautious when applying vinegar, as it can also affect surrounding plants and soil.
