Organic agriculture uses organic seeds or untreated conventional seeds when no alternative exists. In both ways, seeds can carry diseases and are better treated using a method which • is acceptable for organic farming, • has a good success rate at disinfecting the seeds and • does not significantly reduce the germination rate. Prior to sowing your beans, this simple method can reduce or even remove seed infections. For this you will need: a container, hot water (55°C), cold water and a thermometer.
