What is it about?
UV-C radiation (254 nm) is an alternative and efficient method to control seed infection. Eight or twelve hours of exposure to UV-C (57.6 or 86.4 kJ m−2, respectively) reduced or erradicated anthracnose in lupin seed. These UV-C doses increased concentration of chlorophyll and protein contents, as well as increased the activation of defence enzymes peroxidase and catalase, in comparison with seedlings grown from infected seed. Moreover, 57.6 kJ m−2 reduced transmission of the pathogen from seed to the plantlets by 80%, while 86.4 kJ m−2 apparently eradicated the pathogen, under greenhouse conditions.

Why is it important?
The use of UV-C, first reported here, is advantageous for controlling anthracnose in lupin and could be applied to reduce seed infections in many other crops.
Perspectives
It was a pleasure to share with the scientific community and people in general with an alternative and efficient method that contributes with seed management.
