Subsequent inoculation experiments executed less than controlled conditions, exposed considerable variation while in the susceptibility of plant populations to your rust, with a few exhibiting immunity (no an infection noticed).
I. glandulifera will also be controlled by chemical suggests. Use Get hold of weedkillers on them ahead of they kind seed capsules, remembering that the earlier This can be completed, the better.
In the event the vegetation have now set seed, they might be burnt on web-site, if at all possible.
