I have a severe root knot nematode problem. This requires me to grow nematode resistant tomatoes to have any chance of producing. To complicate matters, I live on the TX Gulf coast near Galveston bay. Our spring tomatoe growing season ends in mid June when the temperatures start reaching the high 80s to mid 90s. I prefer to grow indeterminate varieties and have grown the "Champion II" for the last couple of years, with reasonably good results. I am currently trying " Ultimate Opener" for the first time, along side the proven Champion II. Can any one recommend a short season, indeterminate, nematode resistant variety which I could try next ? Thank you for any advise.

Welcome!

Check with Totally Tomatoes. If you can't find anything in their catalog, it doesn't exist.

Hi there Patrick πŸ˜€
My dad taught me a little secret.
When you plant your tomatoes.
Put one tablespoon of sugar in hole first. It takes care of nematodes.
I don't know why.
But, It works.

Have a GREAT DAY πŸ‘

If you plant French Marigold/Tagetes patula it will/might help reduce the population of the nematodes.

Adding sugar I think encourages beneficial microorganisms that...I have no clue, but they do something to help reduce the problem with nedmatodes.

As far as tomato varieties, I just buy whichever seeds have the most letters after the name. Since I live in Georgia I use Walter Reeves as one source of information. Here is a link to show the letters and what they mean.

Thank you for the sugar advice. I will definitely try this. I have been battling this issue for quite a while and trying several varieties in attempt to find one which performs best. Last fall I planted Champion II , Celebrity, and Bettet Boy. When I pulled the old plants out, inspection of the roots showed a dramatic reduction of nematode infection on the Champion II roots. They also stayed much healthier than the other varieties. This was also my first time to use the product "Mykos". Being the first use, I cant really say how much effect it had, but it certainly did not hurt the nematode issue. Possibly combining the sugar with the Mykos micro organisms will be the ticket. Thanks again for the advise.

I have been searching for further information / supporting documentation for the use of sugar as a nematode deterrent. It's not that I question the validity of the recommendation, but I am an engineer, I can't help but research things to the max. What I keep finding is information on the use of agricultural molasses. This seems to substantiate and validate the use of sugar. The molasses is high in sugar and also provides other desirable nutrients. There are documents which recommend the use of molasses to control nematodes. Can any comment on the use of molasses for gardening ?

Hi Patrick,

I understand your dilemma with the sugar and nemotode thing. If I can't find it in some research someplace, I don't bother to try it. In this case, if adding sugar to the planting hole was the cure all, there wouldn't be so many nemotodes in the world.

As far as I know, to combat nemotodes, you plant resistant plants or you allow the ground to remain fallow for enough years that the nemotodes starve to death or you introduce something like beneficial nemotodes to eat the root knot nemotodes.

In the fall, after you pull your garden (and after growing nemotode resistant plants), tilling deeply and exposing the nemotodes to sun will kill them but, once again, a multi-year project.

Sorry!

A year of so ago, I mentioned to a fellow member the sugar thing, for nematodes in garden, my daddy taught me.
Wow ! BOY, OH BOY !### I got JUMPED, by several members. One even told me I was going to poison myself. HogWash, I'm still alive today ! Hilarious! nodding Whistling

So one day, just for kicks ! I Googled sugar for nematodes. Had no problem finding answer. Some "studies" sad it works, and of course, some "studies" said it Didn't.
There was no mentioning of it turning to poison.

I also read about using molasses for nematodes. Of course that makes since ! πŸ˜€ ! Molasses/Sugar, one is by-product of the other.

I believe !?!? the "All things gardening" site has an article about using sugar in the garden.
It's also a good resource for garden information.

Best to you friend πŸ‘πŸ‘πŸ˜Ž

Patrick, are you also solarizing your soil where the tomatoes grow, through the hot summer months?

We grow tomatoes in raised beds at our school garden, and had a big problem until we started just tilling, and covering the beds with greenhouse grade plastic for the summer. Since then we can grow any tomato and have not seen any more root knots when we pull them out at the end of school.
