The registration of the new triazole, Revysol, late last year is a welcome introduction to the crop protection scene on these islands. This is because of the continuous weakening of the triazoles, the loss of the strobilurins, the concerns over the SDHIs and the imminent loss of chlorothalonil. Together these issues have worried grain producers for the past number of years.
The instant concern is that this is yet another triazole, and it is, but with a modified structure. This would not normally be enough in today’s climate of evolving biology, but it seems that Revysol is much more than just another triazole. Never before did we have such a handle on a new molecule at the point of its introduction.
