What are these little things on my potato roots/stems?

Posted by Evamc Ireland (My Page) on

My 'Salad Blue' potatoes blew over exposing their lower stems and some roots, and I found bunches of these little egg like things on the soil/stems. See picture. From seeing pictures they dont look like potato cyst nematodes and they are not stuck, they come off when you touch them. Close up they are like a very feint blue colour but look white from further away. Any idea what they are?? Whether its going to affect my potatoes or whether they are just some kind of harmless insect egg or fungus?

Thanks a lot

My first impression was fungus growth, possibly Pythium Root Rot but the roots in the pic don't show any blackening that I can see. Are the plants themselves showing any problems? Wilting? Softening of the stems?

Has it been exceptionally wet or is the soil there unusually slow to drain? Both can encourage P. root rot. But sometimes as the soil dries new roots will develop and the plants will recover.

If that is the case then a good fungicide application will help the plants recover IF the soil can dry out.

Do you have a lot of pill bugs? I was having problems with pill bugs eating my newly sprouted gourd plants inside pots. I kept planting new seeds and they kept getting eaten. I decided to flood out a pot and found a bunch of pill bugs and what looked like little white floating eggs. I dont know if those were their eggs but that was my guess and they look like what's on your pic.

Hi,

Thanks for the replys. There is no damage to the plants, in fact they are a few of my healthiest looking of the varieties. So I dont think its the root rot u mentioned.

Mav72 if you mean woodlice, I have lots of them but they never seem to cause a problem, and there dont seem to be any near the potatoes

My best guess is that its some kind of harmless tiny fungus.

Thanks

Good. Happy to hear the plants are healthy. Given that I wouldn't worry about it either.

They are just some kind of fungi. Or tiny mushrooms?

Yea, that's them... They usually leave older plants alone but they're a pain when direct seeding, growing soft fruit near the ground, or growing plants with tender leaves...

Good to hear that your plants are healthy.... Your plants are probably just good habitat for them bugs...
