During the last couple of years, I have observed those lilies that I have utilized in crosses having less botrytis. And using different ones that were effected last year, this year, I notice having no problems this year, while others have (notably podless ones). It has been a very, very wet year here. The pollen was not too good during certain periods of excess rain. I pulled the anthers on one and there was never any pollen. It almost looked like what could have been used never got that dusty look. I looked more like it was glued on there instead.
I've also used a great deal of Neem Oil this year, hoping to prevent all sorts of things, though always avoiding the flower itself. I liked it, hopefully it does the job.
