on thrip management about the same time. Here we go: Quote:
It could be that both blue and yellow sticky traps will catch thrips, and for garden pest control one might want to use one of each wherever you place them (instead of one or the other) if one can get both kinds for a reasonable price. (One could also get Tangle-Trap in a can and apply it your own card stock, but I do not know if that would really be cheaper.)

Would this be TSWV? Or some kind of bacteria speck, or maybe septoria? I'm leaning towards TSWV- this popped up on half of my plants literally overnight. I had one sick plant that I didn't pull right away as I was trying to figure out what was wrong with it. Two days later half of my tomatoes have this. I have seen an occasional thrip in my yard but never seen the on the actual plants.

Are the photos you show of newer leaves, or more towards the ground?
It looks like TSWV to me, but typically I see the new foliage show the symptoms first. Also, you can inspect the flowers to see if you have thrips as that's where I usually find them. I like to plant yellow marigolds to keep the thrips away from the tomato flowers. It seems to help in my case. Lee

I can't say what that is, unfortunately. It could fit a few things, including TSVW. I'm pretty certain I had that last year, so the carrier thrips are/were in the N. Tx area. If you have thrips, check the blossoms...they love to go there. The blossoms will quickly wither and turn brown if they are under attack. I've applied Spinosad one time this year because I saw some thrips back in April. I've also used need twice and insecticidal soap twice, fyi. I'm holding off on using take down until something catastrophic looking comes along. Sorry to see this! ;-(

It could be TSWV but it could also be caused by heavy rains over an extended time. If it is TSWV you will know for sure in a week or so on young plants as the growth tip will start to look burned or withered. If it is bacterial you can spray the dilute bleach spray on the plant or apply a copper fungicide and see if that helps. If it proves to be TSWV and the plants are young then they need to be pulled and replaced. Older healthy plants can sometimes withstand TSWV for months before dying but young ones don't last too long and have little chance of producing any fruit.

Thanks guys! I appreciate the help, since this is my second year growing tomatoes I don't have enough experience growing tomatoes to diagnose this problem on my own.
This really looks like TSWV but this is also happening on plants that have not flowered yet, and it's not always on the newer leaves. Sometimes it appears on the lower leaves, sometimes it's on one stem in the middle, and sometimes its the ones at the top. I checked the ones that did have flowers but didn't find any thrips hiding in there. We did have a couple of rainy weeks last month, but it's been pretty dry this week. I have drip irrigation installed on the tomato bed, but I should check to see if the sprinkler from the lawn might be misting the tomatoes. My next best guess is bacterial canker, or potato virus Y |

Maybe this is worth metioning, a 3-way heirloom cross that is supposed to be TSWV resistant.

I have been seeing some thrips in my garden the last few weeks. I'm keeping my fingers crossed that few or no plants will become infected. I saw my first case of TSWV around here on Tuesday at a friends house. He was showing off his tomatoes and I was walking along admiring them when I came upon a beautiful grafted Mrs. Benson that had TSWV. He is only a few miles from me and only has about half as many tomatoes growing as I do so chances are I'll be seeing it soon.

Bill (aka Papa Vic) will have to enlighten us, if he so chooses, which TSWV tolerant variety he crossed to make this one.
However, no TSWV tolerance is inferred for this particular variety. Bill, Sorry to hear TSWV may be headed your way... hopefully you'll survive with minimal to no infection. I may have it on a Plum Regal plant, but at this point, I'm not sure due to the effected leaves being old and new, and not just new foliage..... Lee Quote:

I have lost 4 volunteers and 4 of my large grafted plants to TSWV so far this season so this is turning out to be a fairly bad year for it. I've also lost a few bell peppers. I hate it that it is in my best looking Brandywine Sudduth's that has a wonderful fruit set but I don't know if any will make it to ripe.

This past week I lost 2 more bell pepper plants and 4 more tomatoes to TSWV so this year is turning out to be the 2nd worst year for TSWV for me since I started gardening.

Since my last post on this subject I have lost another couple of tomatoes and peppers to TSWV. It just keeps popping up here an there with no rhyme or reason. No two plants next to each other have gotten it either which is unusual. The plants are totally scattered throughout the garden. Oh well it has opened up a little space here and there giving me a little more room and allowing better air flow. Looking on the bright side.
