Botrytis and copper fungicide - questions

Posted by grandma_gardener_02 z5 PA (My Page) on

Do bulbs transmit botrytis? I.e. do I need to dig up bulbs after a bad case of botrytis?
ALSO, is treating it with copper fungicide too toxic? If the copper is in the soil, will it prevent lilies from growing next year?

Really need to know answer to these questions, because I dusted the ground with the copper fungicide after I dug up diseased plants. Can I plant new bulbs in the same area after doing this?

Yes, copper is toxic and can lead to many diseases. Just google it and you will know. Just because something is occuring in nature does not mean you should use it anytime and anywhere. Just think, if people after you will want to grow vegetables in this place? Is it really necessary to use chemicals to protect some sickly lilies?

As with anything, it is all a matter of dosage - drink enough water and it can kill you too.

I would still recommend drinking unpolluted water. It is extremely rare somebody dies because of drinking pure water. Poisoned water is not good to drink for anybody. I do not have a link to support it, so you choose yourself if you believe it or not.
