Fungal treatment for VFT
Posted 17 July 2012 - 11:17 AM
One of my seeds has started developing what looks like a grey/whiteish colour fuzz on one end. Is there a fungal spray that can be safely used to kill it without harming the plant?

Any preferably systemic fungal spray, preferably without copper in will do the job on fungus, but if it is botrytis carefully cut off the affected bits, treat with flowers of sulphur and burn the affected bits. Be careful not to move the diseased bits around too much, that will spread the spores and make things a lot worse. Then give the plant plenty of ventilation, it hates good airflow, perhaps put it outside for a week or so if possible and see how it responds. Others I have heard have had success with scorching it off with a blowtorch, but this obviously requires care and a 'feel' for how long to expose the area to heat for.
These days you cant get a chemical botrytis cure I'm afraid, a lot of growers are trying Trichoderma, as a preventative, but evidence for its efficacy remains anecdotal.

I would try and get a photo but my camera isn't that good to photograph such small seeds.
The possible fungus is only present on the tip of the seeds, where the roots would emerge.
Because i am a novice with this, i don't really want to try and cut off the infected area or use a blowtorch, my hands are not very steady for that.

You might try to find a suitable fungicide. I rarely need it, but when I do need to use a fungicide, it seems like one with the active ingredient chlorothalonil works fairly well for a wide variety of fungal growths.
The shiny black shell of Venus Flytrap seed is tough but thin and brittle. When the seeds are shipped, the seed coat can often be cracked or crushed (in postal sorting machines, for example) making them more susceptible to fungal infection. The germination rate also suffers because of this damage. So care should be taken when shipping Dionaea seeds.
At any rate, good luck with your germination project.

I live in the United States, where fungicides containing chlorothalonil are distributed under several different brand or trade names, including Daconil, the fungicide I use.
Can you suggest any product names?

I've been carefully checking the seeds, it's so difficult to see them amongst the soil, it looks like out of 21 seeds in total, only 3 or 4 have this mould on them.
