Tomato Spotted Wilt Virus (w/ Pix) - Page 11

grizlbr · July 6, 2011

It would seem I found the culprit now to go spray! I hate to let tomatoes go to waste are they safe to eat?

The first tomatoes were treated with Sevin and Max so do not think the Ortho Max caused spots???

Did not see anything after small cut worms Max was just easier to apply.

Guess I will take a mirror so I can see underside of leaves? The eye level 6 foot portion of my Early Girl looks OK? If she has a STD? Seeds are ok stop rooting suckers????

Is there a chart of diseases to determine what if is going on?

Found my first case of TSWV since June this morning when watering. I hope it will be an isolated case. It was just starting and I cut off the whole stem in the vain hope of slowing it down on the plant. I always try it but it rarely helps. It was one of my fall plants set out in July and it was looking pretty good with a fair amount of blossoms. Seems to me I mainly get TSWV in the spring and sometimes again in the fall. I guess that must be when thrips are active down here.

I have now had 3 cases of TSWV this fall and have pulled them all. I guess the thrips are moving around again.

Just a heads up that the SouthEast is having a massive outbreak of tomato spotted wilt this year. It seems to be a result of a warmer than normal winter and wetter than normal spring.

Yep, we are getting into the nineties now with higher humidity....that time of year to be on guard.

Definitely battling TSWV here in SE North Carolina this year. I have pulled appox 15 plants thus far to include both of my ARGG, Amazon Chocolate, Anna Russian, Lucky Cross, 2 German Johnsons (I really can't get these things to work), Cherokee Green, Kimberley, Black and Brown Boar and a Paul Robeson. Somewhat my fault as I was slow to properly diagnose as I thought the black spotting was a fungus. I really need to bone up on my disease knowledge.

How long have your plants been in the ground, before you noticed a problem?

I was also reading about thrips recently: this article from Florida is very informative about thrips and TSWV, and results of different treatments in the field:

I have been suffering a thrips infestation on pepper plants which are still in the house.

I don't see any signs of TSWV afaict, but I am not going to put any peppers in the greenhouse with tomatoes just in case. The thrips damage alone is nasty enough. Really no way to kill the bugs once they are in the plant tissue, only cull and prune.

Has anyone used diatomaceous earth on the soil surface to stop new ones from emerging? Does this help?

Happens every year - today I lost my first (and hopefully last) plant to TSW - and as usual it is something pretty special - Yellow Ponderosa, from seed saved in 1995 - I got the seed from the USDA. Fortunately I managed to get several up and growing so it is already replaced. It was planted on May 4, and had open blossoms. Looked fine as recently as 2 days ago. Amazing how fast the disease shows up once the plant gets infected.

Weird - plants next to it and across from it are fine. 200 tomato plants. And...boom!....there it was with the characteristic foliage markings.

gardenmama · May 25, 2012

I lost my first (and only so far) plant to TSWV yesterday - sadly it was the only Druzba I had in the garden with no backup plant in the greenhouse. I replaced it with a Black Krim. The other 84 plants look great (for now).

Most of my planting was done ~30Mar thru first week of June. First noticed probably around first of May.

I just quarantined 2 yesterday w/TSWV! I also have early blight, septoria and a couple of leaf curl viruses... most issues have all appeared within the week! Out of the 380 tomatoes I started, about half suddenly have something wrong. Last year I only had a few cases of blight and nothing else. I guess the lack of a winter here is going to make this year a tough one.
