blight

[beanie]

some of my greenhouse plants are showing signs of blight. all I have available at the moment is a rose fungicide. Will it work on this particular fungus.

[Chuckles]

Oh dear Beanie, not good. I'm afraid I've not got a clue but I would assume there are certain types of fungi that are of the same family and would be treated with the same fungicide, hope that makes sense . A starting point might be to look at what is in the rose fungicide and then have a google.

I bet someone on here has this sort of knowledge on the tip of their tongue, hope you get some help soon Beanie

Beanie - please don't do this because I have said so but.....

I have used rose fungicide on other plants (bank holiday and I needed to act) and it worked but if you try, please remember that it might not work, which would be the least of your worries really, but more importantly, it might finish a couple of plants off.

What type of plants are they Beanie? And what symptoms are they showing? I will look in my Hessayon pests & diseases book for you and post what advice is available.

The greenhouse was washed down with diluted Jeyes before any of the plants went in. The plants mostly affected are Impatiens and some of my Fuchsia cuttings. I was really pleased with them, the Impatiens are still flowering their heads off. The foliage has grey fluffy spores on it and some of the stems are rotting. I'll try some of the rose fungicide as you suggested R.F. There isn't anything that I can't replace if need be.

If I were you Beanie I'd dump the Impatiens, they are so fleshy that as soon as they are attacked by any type of fungi you have no hope You may be lucky with the Fushia. Removing the leaves would help, this is what a lot of folk do to over winter them anyway

I agree with Chuckles Beanie - chuck the impatiens. It would be a good idea to take any affected leaves off the fuchsias and I don't think it would hurt to give them a spray with rose fungicide.
I noticed that some of my geranium cuttings had a bit of botrytis so I have removed affected leaves and sprayed them - I am also going to keep an eye on my watering as I think if the compost is too wet they are more susceptible to problems
Hope this helps

I sprayed with the rose feltilizer including the compost and cut the plants right back and so far, fingers crossed, things seem to be O.K. If it re-occurs I'll take the advice and throw them out. Thanks for all the suggestions
