You can make blight a thing of the past by breeding your own tomato and potato varieties that are virtually immune to blight. It's called Horizontal Resistance breeding.

Here is a good link that spells it out:

pick the "Amateur Potato Breeder’s Manual"

It takes about ten years to do it. But once you've got it, it's resistance will last longer than you ever will! It just takes a small group of people, some land, a shovel and a kitchen blender. No PhDs, million dollars labs, piles of cash, etc.

My grape tomato topsy turvey plant has tiny brown scales on the stems that seem to be killing the plant. What can I do?

My grape tomato topsy turvey plant has tiny brown scales on the stems that seem to be killing the plan. Can I use a spray to take care of this? Evelyn in MD

Does this kill other crops as well as tomatoes and potatoes? My mullberries have suffered the past two years as well.

I purchased a tomato plant a month ago. It was doing very well. It started to get yellow flowers all over it and tomatoes were starting to grow. Then a week or two later my flowers started to fall off and then it started to wilt. All of my other plants such as cucumber and green pepper and also other melon plants are doing very well. I have given them the same amount of water each day. I have not skipped a day without giving them water. what has happened to my tomato plant? I have even given my plants miricle grow. Please help me with my tomato plant!

Cesar,
I live in TN and have noticed that my German Queen varity is not making tomatoes. The blooms come and then die about 1/2" back on the stem. From my reading it seems to be "Blight". The plant is very tall and healthy looking but is simply not doing it's business. All the other varieties are doing very well. I guess I won't have any German Queens this season.

I planted tomato plants on 3/31/10. About 4 days ago, noticed that the leaves on 1 or 2 of the plants looked like they are drying and curling up. Now it's happening to all of them. I looked up tomato diseases and it sounds like "Leaf Roll". The stems look good but the leaves are dying. HELP!!

I had bought this tomatoe plant from home depot.
it was only inches tall. ive noticed it became larger.tomatoes are starting to grow but it looks like they are opening at the bottom with some black looking flake around the buttom aswell.
I live in miami.I water them twice a day (sunset&sundown) i also give it miracle grow every week and fish infusium every other week. i take well good care ..so whats going on with these weird looking tomatoes.By the way they are HeartLands hybrids.

Thanks,

Yosy P.

Looks as if the plant is not watered enough...they tend to get black spots on the base ,and if watered sporadically they have a tendency to split.So little and often!

I keep hearing about blight? what does it look like? I have beautiful tomotoes and then the top of the tomatoe is yellow and will not turn red. The rest of the tomaote is beautiful and ripe but the top is still yellow and hard.

The black something on the bottom of your tomatoes is cause by a nutrient deficiency usually a magnesium and calcium deficiency.The black bottoms on your fruit is called blossom end rot.

Suggestions:
have a soil test done .and can be corrected by adding lime which has calcium and magnesium .

My tomato is producing a black something on the bottom what is it?

I had skimmed an article somewhere regarding planting tomato seeds directing in the garden in the fall. And when they come up in the spring you can transplant, the theory sounded like it was based on the voluntary tomatoes growning all over the garden from the previos years spoils. Alas, I can't find the article to get all the particulars a on this process. It always seems that my voluntary plants are much stonger and healthier than my store bought ones. Of course I am "blessed" with an abunbant supply of cherry tomatoes when I'd like to have Roma or Big Boy. Would you have any insight of this proceedure. Thanks Jeanne Will Hammond Wisconsin....

I live in Miami. Very hot temperatures, in the 90's. My German Queen tomatoes have grown up to six feet and look very well, but no fruit. Is it the temperature? I planted them three months ago. Too soon to grow fruit?

Can you explain what causes very hard, yellow cores in red tomatoes?

I was in my garden on Monday the 20th tying up the tomatoes and they were fine. By Wednesday the entire crop was dead...browned out with white fungus all over them. I had 15 tomato plants and it's breaking my heart to know I will not have one of my own organically grown tomatoes this summer.

1. My Roma tomatoes are valiantly trying to grow several tomatoes, but out of 4 one had been eaten or otherwise producing a black something on the bottom.

2. The other, a huge plant bought as a small plant from the grocery store and potted into a large pot, got many blossoms but no tomatoes. It is a Super something.

I read an article in the Philadelphia Inquirer last week. The article said if your tomato plant has this, pull it out but put it in a plastic bag and lay it in the sun until you can see it is completely dead. Then put it in the trash. I have cut the article out of paper and shared it with some friends. This is the same blight that hit Ireland in the potato famine in 1842. If you wish for more info.
