interesting to see how it works out
Having some trials with tomatoes this year, struggled with cold, followed by accidentally cooking my seedlings with unexpected hot weather. now have toms in gh, but they are way behind. in my other gh I have some sort of pest, which is eating the roots of anything I plant, killing the plants. I had a small issue the same last year. I have been out day and night with torch to try and find the pesties, but not finding them - but the style of damage suggests some sort of cutting worm/weevil. I have, for the first time in my life, decided to try nematodes, it feels like that or not use the greenhouse ever again.
not looking like it will be a tomato glut year for me. Good I can use up last years frozen...... |

Sounds like I should be grateful to not know about vine weevils...
Over here I would suggest also checking for seed corn maggot, though I don't know if you have them there. Nematodes would also be effective for them.
Have you evaluated your risk for damping off organisms? I've seen situations where pythium gets out of control in greenhouse soil. Nematodes would not help with damping off diseases... |
it is definitely something eating them - the roots are eaten away and the 'bark' of the stems stripped, then the stems eaten. It is not the style of slugs or snails, a foe I am familiar with. I have applied a broad spectrum nematode, as my research points to various larvae/ grubs of various moths or weevils, and all I can do is continue to replace plants and see if the problem stops. Last year only tomatoes were killed, and I grew lots of cucumbers, but this year the pesties took out a courgette plant that was thriving, then suddenly not. Everything above ground looks ok, but suddenly droopy, dig under the soil and the stem is chewed through, the other roots gone.
I think nematodes are a relatively ok thing to use. and I have to do something to get my greenhouse back. |
