What's the matter with my potatoes?

That's about all you can do. Hopefully whatever it is won't affect all of your veggies. Hoping you will still have a good harvest.

Instead of guessing, why don't you take a fresh-cut specimen to your county ag-extension office??? Chances are high that they can identify it for you.

I just called them and they will be in tomorrow, so I think I will do that. Thank you! Never thought of doing this.

At first it was just one plant on the end and then the one next to it, but now it is here and there on other rows, several different varieties of potatoes. The plants looked good and then it seems the top leaves are curling and turning brown or gray. I do not see any bugs or holes in leaves. I am worried about some kind of weed killer from manure brought in or strawView attachment 20138 View attachment 20139 . The manure spread on the garden was picked up last spring and used in the compost bin and spread on the garden last October and tilled in this spring and straw for rabbit beds was composted. The hay the rabbits eat is so called organic Timothy. Should I pull these plants? Should i cut off the bad leaves?

may be wrong but this sure looks your problem....

Look up potato leafroll virus.

Herbicides don't work/carryover like some of you believe. If it was herbicide damage from manure/straw it would take out ALL the potatoes plus your peppers, tomatoes, etc. all broad leafs would be dead.

Dow's website warns about carry over on this particular one.

• Aminopyralid is broken down by soil microbes.

Or through composting.


What they are warning you about is applied to pastures, it will be in the hay. Won't hurt animals so passes through the gut untouched. If you use fresh manure, can be a problem. If it was chemicals, it would kill all the susceptible plants-not just a few and it wouldn't start and stop. If it starts on one plant and spreads, its most likely to be a disease or insect.

It really does look just like what I have on the potatoes. The tomatoes are okay so far. Cabbage, kale and collards they say can grow and not show any signs of damage, but lettuce and sunflowers will. I have lettuce growing and sunflowers are coming up and look fine. Some of them are in the compost bin where a lot of hay and manure would be. I am going to call before I go to the extension office and see about soil samples and test for this.

Some of the pictures do look like it could be leafroill. I do not have peppers planted yet and the tomatoes have not been in very long.
