What is it about?
A solar UV-B radiation oven was developed for seed disinfection that uses sun-light as clean source of energy. Short exposure times for 30-45 min of lupin infected seed placed in this solar UV-B radiation oven efficiently reduces seed infection. This treatment is more efficient than individually, dry-heat or UV-B radiation at ambient temperature because the solar oven concentrate UV-B radiation plus temperature. In addition, the pretreatment of lupin seed with low UV-B/temperature-treated (doses of 2.83 or 3.85 kJ/m2 at ≈ 76oC) increased total concentrations of chlorophyll, protein and peroxidase activity in plants. Irradiation also reduced by 85% or eradicated transmission of the pathogen from seed to the seedlings under greenhouse conditions.

Why is it important?
This is an efficient clean source of energy for seed disinfection and to enhance physiological and biochemical responses in plant https://www.youtube.com/watch?v=YdJVL_qIsYY
Perspectives
Our solar UV-B radiation oven was developed for anthracnose lupin seed disinfection, however preliminary studies shows that it is efficient to control other bacteria diseases infections in other crops as well as insect infections in tubers and roots.
