Introduction: Benomyl is a systemic, benzimidazole fungicide that is selectively toxic to microorganisms and to invertebrates, especially earthworms. It is used against a wide range of fungal diseases of field crops, fruits, nuts, ornamentals, mushrooms, and turf.
The common explanation for his is that sneezing was a symptom of the Plague and so if someone sneezed, people would say 'bless you' because they might have a horrible disease. But in fact it dates from much earlier superstitions, for example, ancient man believed that his breath was also his soul or essence of life..
1 They say an infected person's sneeze was a sure sign he'd soon be pushing up daisies, thus the Bless you! was intended as a benediction to the nearly-departed, a way of commending his soul to the care of God now that he was beyond the help of anything in the mortal world.
