Researcher Joop Esselink of WUR explains that the potatoes of the test varieties Agria, Fontane, Innovator and Nicola were last assessed in mid-May for external germ, internal germ, storage loss and general quality. The potatoes are stored at 7 degrees with outside air cooling. Chlorine IPC was administered four times at a recommended dose.

‘At Agria, there was hardly any germ formation on the tubers during the entire storage period of the treated objects. The other three varieties did show some external germ in the last assessment, in both Chlorine IPC and MH, ‘says Esselink. ‘If we look at moisture loss, MH scores on average slightly better than Chlorine IPC.’

MH is particularly strong in combating internal germs in a sensitive variety such as Innovator, is Esselink’s experience. With Chlorine IPC, the share of internal germ in this variety in the storage study was almost 11 percent. No internal germ was found in the samples from MH-treated potatoes.
