@cleiper, I hope you are right. That's what I told myself last year and then picture #2 happened, and worse. It took me years to figure out it was thrips damaging my nectarines. I don't I know why the subject of the damage they do on their I and veg doesn't come up more. Then I found these examples of thrip damage on tomato leaves.

Got me thinking. Other pictures in my search focused on the small block speckles of thrip poop (frass), and I think I see that near the edges of the close up pictures of this year's leaves.

or Cyhalothrin aka..Spectracide Triazicide Insect Killer for Lawns & Landscapes Conc.; & RTS2 I don't know if it is labeled for direct use on the plants but it is on a chart for controlling them on tomatoes. on the following....

Those are pictures from an internet search, but I thought they resembled mine.

Spinosad and DE on a every 3rd week basis. I have not lost a plant to TSWV since.

How much DE do you mix in per gallon? Does it clog your sprayer?

I sprayed it. Didn't measure anything but made sure it was mixed well.

I just started spraying DE mixed with water and Dawn soap according to something Bill posted in another thread. I have some Spinosad can I add it in. I usually have mites of one kind or another.

I dont spray it i dust it on using a Dustin Mizer. I found it works better than spraying it on. Just remember to use a dust mask.

Do these pests and remedies vary with climate? Somehow I wonder if thrips, mites, and MAYBE aphids might be an especially hot and dry thing, while blights are not so much.

I use between 2/3rds and 3/4 of a cup of food grade DE for every gallon of spray I am making. I mix it first in a separate jug and then pour it through a strainer into my sprayer then add the other ingredients and extra water to make the amount I am looking for.

I don't see why you can't add Spinosad without any problems. I add Permethrin and Dawn and if I need to use a copper spray at the time I am using it I will add that and have had no problems.

I find spraying much easier than dusting and just as if not more effective but then I am applying it to a lot of plants. If it is a bit windy which it always seems to be this time of year dusting can be challenging to say the least. I do use it in my duster when I don't have many plants to treat and don't want to mix up a small batch for spraying.

Bill, do you happen to know the screen size on your strainer? I am going to mix up my first DE spray soon.

I use one of those fine stainless steel small strainers with a handle that you can pick up in any good super market or Walmart. They are the ones with the fine mesh but I have no Idea what the screen size is just that it is fine.

Oh yeah. I forgot to remind you to occasionally shake your sprayer to keep the DE in suspension as it will settle. I also recommend not setting your nozzle to too fine a mist or it may clog. If that happens just open it up to a stream and clear it with a short squirt. At least that is what I have experienced. The amount of DE I recommend is fairly high but I have found it is just high enough to give a good fine layer of DE that is effective against most pests. I have used smaller amounts but found they were less effective and I have used much larger amounts and found they clogged my sprayer too often; but if I got it sprayed on it was even more effective.
