Biological weapons include any microorganism (such as bacteria, viruses, or fungi) or toxin (poisonous compounds produced by microorganisms) found in nature that can be used to kill or injure people.
Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Biological warfare is the deliberate spreading of disease amongst humans, animals, and plants biological weapons (bw) introduce a bacteria or virus into an environment for hostile purposes, that is not prepared to defend itself from the intruder. Virus, an infectious agent of small size and simple composition that can multiply only in living cells of animals, plants, or bacteriathe name is from a latin word meaning “slimy liquid” or “poison” the earliest indications of the biological nature of viruses came from studies in 1892 by the russian scientist dmitry i ivanovsky and in 1898 by the dutch scientist martinus w beijerinck.
