Green house sulphur candles- brand DEAD FAST & botrytis

[David23]

High I am very confused. There are two types of sulphur candle. One made by vitax which definately requires all plants to be removed. And the Dead Fast brand. With the Deadfast brand some sellers say it removes the pest and diseases on leaves and in the greenhouse as well. Suggesting that you need not remove any plants. Other sellers say this same product should have all the plants removed before.

I have a botrytis problem. I am currenty going round removing the plant or stems or scooping it off stronger stems.

Can I use the sulpher or anything else that kills grey mould. Will stronger plants be effected ?

They are new plug plants that I talked about before.
