I grow a grafted tomato variety. The rootstock is supposed to be nematode resistant. However, several plants in my greenhouse collapsed and when I checked their roots I saw galls full with nematodes.
How can this happen?
Nematode resistant is less efficient when soil temperature is over 27º. This could be the reason that several plants in your greenhouse collapsed and have some galls with nematodes.
I hope that you will enjoy our rootstock performance in your greenhouse.
