First, I would like to ask everyone: when you spray with Daconil, what sort of mask do you use?
===
And secondly ... Coconut Head, when I look at them in my mind's eye ... well, at the moment they are arguing tactics. And arguing. I don't understand the languages, but the mutual insults are unmistakable. The Wizard looks disgusted. Some of the ballista underlings have their slide rules out.
Hope the dragons don't take advantage and ambush them before they come to a consensus.
As far as vegetarianism is concerned: these are obviously canny dragons with the good sense to enjoy broiled beefsteak tomatoes with their beef. None of our plants are safe.

No, Bacterial infections do not spread from plant to plant unless you've been handling the affected leaves and transferred them yourself. And I spoke to splashback infection is a post above. All of the foliage diseases that are NEW are spread by wind and rain.
Am I remembering correctly that you aren't that far from where I garden? I just can't remember. Yes, we had a T-storm that reached here in my area about 4 AM and aside from the one period of high heat it's been cold and rainy here. So foliage diseases, both bacterial and fungal are happy happy.
Have you looked at some disease sites as I sugggested? At the top of this page the Pest and Disease Forum is linked to and when you go there you'll see a thread called Problem Solver.
The best two sites that I think are still there are the Cornell one and the TAMU one.
With no yellow halos around the spots I'd take a good look at Bacterial Spot which does have black somewhat necrotic soft lesions at some of the leaf margins and internally on the leaves as well/
Hope that helps.

I have been washing myhands after dealing with that guy. Now that it's out Hopefully this will all be acedemic. I'm a couple hours west of you but it's certainly possible it was the same storm, and yes, it's been cooler and damp the last few days.
My oneida county extension offices are Cornell Cooperative and actually a few of my facebook gardening group members are Cornell staff. I have looked through thier material pretty well. With no pictures looking exactly like what I had, I was trying to read the descriptions. I wish I had something better than my cell phone to get good pics with, then I could have taken some nice pics. All the ones I tried with my phone didn't have enough detail to really see the damage. The spots were pretty small.

Last year I planted everything out mid March. This year I spread it out much more which seems to be working well. I have a long growing season and dont usually get killing frost until late Nov. or later.
Lots of Early Blight this year.
Brandywine Red, Landis is a real star and trooper. Heavy fruit set and seems to be the least impacted by EB. Moravsky Div has been a great early with lots of golf ball size and larger fruit but it will succumb to LB in the next week.
Have also harvested Rosella Purple, SunGolds, Early Girls, Moskvich (a fave) Druzba, Fourth of July and a few Orange Bananas as well as a few others paste types.

Planted Brandywine, Brandy Boy, Black from Tula, Prue, Better Boy, Cherokee Green, Cherokee Purple, Pink Girl, Opalka, Aunt Ginny, Eva, and Black Krimm (my favorite) on May 1. Lots of fruit set, some the size of softballs on Better Boy, Brandy Boy and Black Krimm. Ate a Black Krimm a week ago. I have never had tomatoes prior to 4th before, except for cherries. Another Black Krimm and Prue will be picked in next couple of days. Better Boys and Cherokee Green are turning. Brandywine is my only poor producer so far, the rest are doing great. This should be a bumper crop year even though we've only had 2 inches of rain total in two rainfalls since May 2. Mid-Missouri is experiencing a drought so I have quite a water bill. I have noticed little disease on plants this year, but I spray every 10 days with fungicide.

It's true that the uniform ripening gene has been introduced into most modern hybrids, which eliminates green shoulders,but that's hybrids that have been the result of human breeding efforts.
But the recommendation to use only cherry tomatoes I think is a bit overboard since there are maybe 15-20,000, maybe 6 to 7,000 available commercially, varieties out there and only a few hundred are F1 hybrids which have been bred, quite honestly, mainly for the large commercial farming industry.
The rest are open pollinated, some heirlooms, some not, and there are many that naturally have the uniform ripening gene and many that don't. Yes, many of the non-F1 ones were also bred, but not many have the uniform ripening gene inserted into the genome, especially the older ones since that gene wasn't known back then.
Taste is both personal and perceptual and there are many variables that play into taste such as where a variety is grown, inground or in containers, kind of soil, if inground, kind of mix used in comtainers, amendments used if any and if so how much and when and what the weather is like in any ONE season when a variety is grown.
But the primary determinants with taste are the genes that a variety has.
The only way that a person will know if he/she likes the taste of a specific variety is to grow it b'c I know I can praise a variety highly and always there's someone who says that they will never grow it again. SOP as long as I've been around.
As for me, there are a few hybrids I really like but most of the now over 3,000 varieties I've grown have been open pollinated and I'll continue mainly with the OP's.
So one doesn't have to go to just cherry tomatoes and small types for taste, as the article suggested, for there are thousands of OP's out there that taste great as I know many here already know. Actually in making that suggestion the article seems to me to be anti-F1 hybrid and not be perhaps up to date on the thousands of great tasting OP's.

Until the last couple years, I was never able to find a tomato that tasted very good on sale in any of the large supermarkets in Southwest Ohio (Kroger, Walmart, Meijer, SuperValu). I think the reason for the recommendation for cherry tomatoes and other small types is meant for those who live in food deserts without access to farmer's markets and upscale grocery stores. One nice unintended consequence of the horrible hybrids in most markets is that Americans are returning to gardening in record numbers, primarily in search of better tomatoes.

I am using evaporation cooling in my high tunnel. It is working great. I am sure it would work outside too. Yesterday it was 106 outside, at the start of the cycle it was 97 degrees in the high tunnel. By the end of the 2 minute cycle, it was back down to 91 degrees. I have 6 spinner sprinklers that run for 2 minutes and shut off for 10 minutes. They have been running from 11 am until 7 to 7:30 pm. They tomatoes are all blooming now and I am seeing lots of them taking!
I am surprised how well it is working.

Jay, years ago I read here about misting used outdoors in the Southwest desert to cool tomatoes, but I don't know details (I don't think we got many details) except that the growers (gardeners rather than market-gardeners) were happy with the results.
Are you spraying above the plants, in front of fans, or somewhere else?
Do the plants get damp?
Luckily we almost never have to worry here about temperatures preventing fruitset. Our overnight lows for the next few days were supposed to be in the 68-72 range -- which is unusual -- but this morning they've altered that to 68 two times and the rest of the nights much cooler.




Gumby - how did you get that alert? Are you on a mailing list from UCONN? USA Blight? I signed up for alerts, also checked the map and USA Blight isn't showing any more cases in CT. I haven't heard back this week whether my samples sporulated, I don't know if CAES is updating anything to say I've got it, but don't see anything on UCONN (ladybug) link above. I emailed CAES this morning to ask about my samples and haven't heard back.
lionheart - what about you?
I've been cutting and pulling leaves all (rainy) weekend, and sprayed today, starting with the tomatoes that haven't been affected yet (ran out of fungicide so will finish the potatoes in the AM). But I noticed my uncle's potatoes showing the same brown withered spots, he thought it was drought stress but I told my cousin it might be LB and wouldn't hurt to spray.

augie,
I feel for you. Those mites are evil. I'd rather battle aphids, whiteflies or even sandworms.
Hope you can rid that one plant before they spread.
Miss ingto,
Consider yourself very fortunate. Our avg temp for this time of June is 86 and the forecast says we might set a record for today of 107.
I've been out on & off for the last couple of hours erecting a shadecloth umbrella of sorts over the plants. I can only last for about 1/2 hour at a time out there in the sun. I'm getting too old for this crap.

40+ tomato plants, all doing well. We had some 90+F temps in late May early June where the plants stopped growing, but cooler weather since have made them take off and flower like crazy.
Created a huge new bed in my sand using only a bit of manure and compost + mulch and those tomatoes are growing fastest and healthiest, actually overflowing and outgrowing cages already which is early here and lots of flowers. Only a few green tomatoes going so far. Containers have the most tomatoes for now, but smaller plants overall. New bed should yield huge amounts once they get going on fruit. They are laden with flowers right now. No pests or disease anywhere so far on toms.
Wish I could say the same for my fruit trees.

EB is soil-borne, not airborne, right? My uncle 1/2 mile up the road (not the one with potatoes and blueberries, he's 10 miles away) has EB and what I hope are just broken dried-up branches, not LB. I mentioned something to him about cutting foliage and spraying, he said they were his wife's plants. She's still working (he's retired) and hasn't planted the 2 cherry toms and 1 eggplant I gave her more than a month ago, so I don't know if she'll do it. Whole area is mulched heavily (by the kids' trampoline, which may be how the branches got broken...).
I've got some Husky Red (still green) in containers, 2 CP and 1 BW (my cousin started early) with fruit. A few of my BW and Glaciers I started from seed in mid-March have flower buds as do the volunteers in the manure pile. I thought it funny that my 50 DTM and my 90 DTM have buds the same time, the other varieties don't yet.


Lyn,
My best to you. Effort counts!
Planting late isn't bad as long as the plants weren't stunted in small pots long. Warm weather can shock them, too. DO they look worse now that they're planted? Perhaps, they need a bit of shade in your hot weather climate. A bit of TLC & they'll recover from shock if that's what you're describing.
Deep watering 1x a week is usually sufficient unless plants wilt. Mulch will help prevent wilting. Your plants may have been quite root bound before planting and just don't have sufficient roots just yet to support growth. Soaker hoses water well and work great for me when I set a timer to turn off after 3 hours. You'll need to figure how long it takes for yours to soak the soil. Another idea is to bury a gallon milk jug with a few holes in it partway in the soil about 5" away from your plant. Water plant, fill jug. Can fill jug, move on to other garden plants, let drain & fill again as you go back to that 1st jug filled.
Feed plants: depends on what you have used. Plants in pots may have lighter green leaves for a few reasons one being nutrients & other being lighting.
I usually apply organic fertilizer (+ lime, bonemeal, crushed egg shells) at planting time and no more, so I can't give you good suggestions for feeding other than mulch with compost and cover compost with straw or dried grass clippings. Neither are fast feeders & won't burn plant if you also have applied another fertilizer.
Roses are heavy feeders, but tomatoes aren't. Be careful as too much feeding = big leafy plants with no fruit.
Sometimes, when I've kept plants in starter pots too long they become root bound & do flower earlier than I desire on smaller plants. Maybe your plants haven't yet flowered because they are too immature to flower.
What kind of damage is there to leaves?
Remove any leaves that might touch soil. Meaning 4" of stem with no leaves present. Those lower leaves won't produce your flowering shoots anyway. Removal of any other leaves above that first flower truss will reduce total number of fruit and yield. However, if damaged or diseased better to remove the leaves and save the plant.
Did you plant them deeply?
wet leaves = higher chance of disease, but if they dry off during the day should be okay
always better to water soil, not the leaves, so again soakers might be useful to you
sprinkler set too high can wreck havek as can a forceful blast of the garden hose
another option is to bury a bottomless large coffee can at least 6" away from stem to fill with water (directs the blast & helps you measure how much water you're applying
For next year - attempt to dig through that glatial rock using a pickaxe or pry bar for a drainage hole. It's not necessary to till it all up -- just layer materials upward to build a deep bed. We have a lot that same rock and have built up with lots of organic matter. Some gardens here have wood sides, but we also have layered up along the driveway and mound the beds pulling material from now permanent paths.
Many posts on GW about building good soil, lasagna gardening, sheet mulching, etc. Any organic matter applied after harvest (+ removal of all tomato foliage) will improve your chances of success next year. It may seem overwhelming to source enough material, but your family probably generates a lot of compost ingredients on a regular basis. When I set up additional paper trash baskets in our bathrooms & a step on trash can in kitchen for compost we increased our compost ingredients with minimal effort. Used facial tissue, toilet paper rolls, soiled paper napkins, cereal boxes, paper wrappings, junk mail, newspaper, etc. More info on the soil forum about what to gather & spread on garden space to improve soil.
Remember one step at a time.
Hope that helps,
Corrine
Corrine...
Thanks for the encouragement.
Some of the things I've learned about growing roses up here are transferable to growing other plants. When I first planted the tomatoes, they did look wilted. I knew the root system wasn't working yet and carrying moisture up to the top growth, so I did shade the plants by hanging a sheet over the fence and across the tomato cages. I do the same thing when I transplant a rose in triple digit temps....no, you aren't supposed to do that, but I can make it work ... Within a day, the wilting had passed. Whew !
Again, with roses, you never feed them until you see new top growth because that is the signal that the root system is working, so that's why I held off feeding the newly planted toms.
Re: the leaf damage. A couple of them look like water stress damage, which would have been caused by the plants being in the small containers for too long. A couple look like they have some insect damage, but I can't see any eggs on the bottom sides of the leaves... possibly katydids. I've heard them in the garden. There is one spot that looks like rust on roses. It's the color of the leaves that makes me sense that the plants are not getting any nutrients. The organic compost that I mixed in with the planting soil hasn't had time to break down to make nutrients available to the plants. I know that won't be an issue next year.
I am a gleaner at heart. I live in the mountains, so I often go out to the forest to get leaves from certain trees and forest duff to put into the rose beds. I also go to the utility company's chipping pile for wood chips to put over the leaves so that they will stay put and not blow away. Yes, any kind of wood will steal nitrogen, but that's easy to fix with some calcium nitrate in the spring. (I also age bags of chips over the winter, so they turn into beautiful stuff by spring.) I do understand not to use anything with a heavy nitrogen content on the toms.
I removed the bottom leaves of the plants before planting and planted deep because I had read that the bud eyes at the leaf nodes mutate to grow more roots, so I don't have any leaves touching the soil.
I generally don't put kitchen waste in the garden because I don't want to draw critters to the garden. We do have some nasty ones up here.
But I had not thought to use my paper goods for mulching. I usually have to recycle all of that stuff. I can see another mound coming ...lol.
I am still not certain as to the "why" you don't wet the leaves. Is it the force of the water ? I know that when I spray down my roses when the triple digits hit for weeks every day, it helps them to be more heat tolerant because the plants absorb moisture through the leaves and the area around the rose is more humid...my climate is quite arid during the summer months. The daily spraying also totally keeps the roses free of spider mites. Is this one of those things that is NOT transferable ? I do know that if I wet them, it would be earlier in the day and I know they will be dry by the time the night temps start to cool things down.
btw ... this has been a very, very cool and unusual spring. We've only hit the 90s for a couple of days and then it has cooled off back down into the 70s & 80s. Generally once the temps hit the 90s, it never cools down until fall. We do have a 40 to 50 degree variance between night temps and day temps. Does that matter ?
Sorry this is so long.
Smiles,
Lyn
