Ultraviolet-C hormesis: an ecological approach to disease and pest control in fruit and vegetable production

At all stages of growth and development, as well as during transport and storage, fresh fruits and vegetables are exposed to the pressure of a number of biological stress factors. In many cases, these stressors - fungi, viruses, bacteria and insects - can cause significant damage, leading to quality...
