Blight: 5 Ways to Control Potato Blight (Late Blight)

Potato blight first shows itself as brownish-black spots on leaves, but before long the potato foliage can completely collapse and the potatoes themselves will rot.

Unfortunately, in many areas potato blight is inevitable. This persistent disease can ruin potato crops in next to no time so it’s important to take steps to limit the damage before it’s too late.

In this video we share five ways to deal with potato blight when it strikes, helping you to limit damage and ensure you still get a crop of potatoes.

Since potato blight is a fungal disease, it makes sense to me to do a preventative organic antifungal spray. There are a number of organic antifungal essential oils that can be added to water in a sprayer. That is what I intend to do this year before any kind of problem even shows up.

I had late blight on my spuds this year. I'm glad I did the right thing but cutting them down.

I like to try and use very little chemicals on my vegetables, so one year when our allotment got blight, I made up a garlic liquid spray and sprayed my potato plants with them every 14 days, 3 consecutive times. I can not say for sure it worked, but mine didn't get blight while a lot of others did.

I think I have blight, but probably fusarium wilt, although there are some leaves with brown spots. I have a device that creates aqueous ozone with a level of 1-2 ppm. I have poured it on the potato soil, as well as sprayed them with it. I am also going to try the baking soda spray which is supposed to help. I am hoping since ozone kills just about every pathogen, virus, fungus, amoebas, bacteria, etc etc., that it will help. Here's keeping my fingers crossed!!

Thank you for all the comments on here. It has helped me to understand what is going with my potatoes.

Can Blight be dealt with Neem Oil?

When this starts to appear you can get special spray that kills the blight you have to get this condition very early if it appears on the leaf or otherwise potatoes are ruined proper store where they sell seed for growing vegetables should have this type spray for blight or garden type centre

I have just planted my Charlotte Xmas potatoes in pots. What's the best way to avoid blight between now and Xmas? I can bring them in an unheated greenhouse or even my conservatory if it gets cold but wondering if this also might delay them getting blight. Or, does blight not attack in autumn!? Any advice appreciated as I've never grown potatoes for Xmas before.

I'm in NE Texas, Zone 7B. We are being inundated with rain! My no-dig potatoes are in in raised beds and are "scheduled" for harvest in just a 2 or 3 weeks. Because of the rain, people have been advising me to harvest all of them now, but most of the plants are green and healthy. However, a plant or two look like they might have late blight, although, not as bad as some of the images I've seen. Should I dig up that plant, just in case it IS blight? Also, if I plant (blackeyed) peas in that bed right after I harvest all of these potatoes (this year), will I still have to rotate the potatoes next year?

[leevandyke]

All I do is cut off all the blight leaves and the leaf stems, gets more air circulation

Sapo Mira potatos are pretty much free from blight.
I think watering from bellow and spacing potatoes apart by 14 inches allows air to pass threw and prevent moisture hanging around on the leaves to long really helps.
Also watering in the morning is a good idea.

I'm a new hobby grower with 3 tomatoes outside on patio and 3 in an unheated flappy zip up 'greenhouse' (it's crap and random holes/slots have emerged over 2 years in it, so even if i close it i fear spores can enter and linger?
There is a red blight warning over my town tomorrow according to blightspy website, and I don't know what I can do for the tomatoes short of leave them in my lounge all day until red dot of doom has passed! They all look healthy at the moment and are in pots. Neighbours either side have no gardening interest. Don't know how worried I should be in this private garden context😬😬

What do you do with the soil the plants were in? Can it be reused for planting or will it get future plants sick?

I have tried Sarpo Mara this year as it is supposed to be blight resistant  out of the 4 varieties I planted Sarpo Mira is the only one to get blight I had to cut off all the tops last week t try and save them
