The application of modulated UV-C light to guavas—emitted in pulses or cycles rather than continuously—combated anthracnose. This fungal disease is caused by microorganisms belonging to the Colletotrichum gloeosporioides complex and triggers dark lesions on the fruit after harvest, reducing its shelf life. An article on the technique was published in the journal Horticulturae.
