Hoping you all can identify what's happening to the leaves from the base out?

Recommendations for treatment?

Thanks!

What have you applied to the leaves so far?

6/4/2022 6:28:05 PM

No fungicides yet. Got some diluted 5-1-1 fish on them when they were watered.

Definitely looks like a symptom of something that got on the leaves. I don't think that would be from fish fertilizer unless it went on full strength LOL. Notice how it is on the old leaves and not the new ones. Whatever caused it, got on the leaves a while back.

I wouldn't worry about treating it. Just give it some time to recover.

If I had to guess, I would say its something in the dirt? That's not a happy plant...

Like moon said, just water, give it some time and hope it recovers! We need to see you at the weigh off this year!:)

Looking again, I would cut those bad leaves off, continue to water every couple days, make sure when using any ferts go 1\4 of the recommendations and hope it pulls through. The newer growth looks good so all isn't lost yet.:)

Thanks for the info! Leaves will come off tomorrow and I'll hope for the best.

You could spray potassium bicarbonate or something to try to prolong the leaves/ stop any disease. The blue fertilizer seems to inhibit disease too, probably the copper in it... If you leave the leaf stalks, the plant might recover better.

Torrance, Ca.

Whatever you do, don't leave the leaf stalk. Trim it off very carefully so there's no area moisture can settle in and dust with a little sulfur if anything all.
Leaving a leaf stalk that close to the main is only going to cause you issues later this season.

Grittyville, WA

If you leave the leaf stalk the top closure of the stalk must remain... dont cut the hollow open it will collect water inside. If people disagree with me, thats fine, except in all likelihood they've never actually tried it.

gourdo, unfortunately for Chris (So.Cal.Grower) when it comes to disease, knowledge, control, prevention and damage control he is a man worthy of listening to. Trim it and treat it like he said.

whats on the underside of the leaf?

Grid, I see that in your diary. Never tried that but I will and yet what I do otherwise is usually cut anything off and since there's a shallow ring left, I also cut a notch into that which always provides drainage, even if it's an upward-facing ring. Whenever I see or type '(The) Ring' now, I think of the movie...not aptly named, if you've ever seen it, lol---eg

This is the wrong way, according to Northshore. Just gotta point out the "wrong way" to do it.

6/5/2022 11:43:18 PM

Grittyville, WA

The story behind why I started doing it this way is I had a vine that was damaged and wilting and I thought "how can I take all the stress off the vine so it can recover, yet leave the plant enough reserves to restart growth?" The logical answer seemed to be to remove the only the leaf surfaces but not the leaf stalks. I tried it and the plant bounced back immediately. I thought wow, that really worked. Why?
I think because the weight of the leaf stalks is almost equal to the weight of all the vines. And these plants dont store their energy anywhere else. So in situations like this it seems to me you can double the recovery rate of the plant by, if possible, not removing the leaf stalks. Lots of sugars and minerals in those stalks, it seems.

Just explaining-- (I'm sure I am stepping on toes too, as always.)

6/5/2022 11:57:36 PM

Other things: It seems that whatever was wrong might be overwith in that the new growth is fine and a little splotchy (I always say 'A plant showing its colors' anywhere else) but the oldest leaves are the worst and soon along the plant they get to be very nice; Perhaps the plant hit some soil later on and deeper that satisfied its deficiency and will move along now. Additionally, the super-oldest leaf had dried up at its leaf surface and as Grid is eluding to and as I might ask of anyone, where did that leaf go, technically, as in did it dry up fully or did some of it go back into the plant whist it was drying up? Did some of that nutrition go to where it was needed and that is why those older leaves are in bad shape and the new growth looks so good? That one brown, shriveled leaf happened naturally - perhaps cutting it off is for once it is about 3" from where it attaches...I would NOT worry about this once the plant is of fruit-bearing age - There is plenty of energy and fertilzer to go around. I am only asking rhetorically - I do not wanna join in on the discussion, really - until I have these issues in a few weeks, lol---eric g

What I see when I look at your leaves is the distinctive little tracks made by leaf miners.

leaf miners should be easy to get rid of by using a systemic fungicide.

There's also a couple of small circular white necrotic spots that might indicate a kind leaf spot. General fungicides like a daconil or a copper fungicide help you to get rid and prevent.

Obviously its quite hard to tell from a picture, so unless you do lab testing, make pictures and document all symptoms and issues of your plant as best as possible and use the internet as a reference. There is a treasure trove of information if you google cucurbit deficiencies or cucurbit diseases. A comprehensive preventive fungi and pesticide plan that targets the pest and diseases most common in your area is obviously the best strategies. And last but not least; don't panic. Don't spray the kitchen sink on it right away and take your time to properly research. Then decide on a solution/strategy and follow through. Plants will lose leaves during their life span every time your grow. Some due to pest, some due to wind or other kinds of damage. The game is about minimizing damage and keeping your plant as healthy as possible for a long as possible. You always lose a battle or two so don't sweat it.

Good luck.

Might be time to hit the " ignore button " again north shore...
No wonder the heavy hitters I talk with don't come on here any more. They say they just couldn't take the banter from the new guy.

Frank and Tina, alwasy great to see your posts!:)

6/6/2022 9:25:35 AM

Torrance, Ca.

Like Frank and Tina said, I always test my stuff because I want to know exactly what I'm dealing with.

Thanks for the kind words Glenn\Northshore. I'm getting pretty good at disease after dealing with it year after year and test after test. lol
I'll be resting my spot in 2023 and have a number of cover crops planned, with a couple other treatments.

Uh Oh Chris, Im surmising that the Gridiot is once again posting his “best guesses” or his making up fantasy solutions again and posting nonsense, garbage based info. (I’ve got him blocked so I don’t see his bull crap)

Yeah, really just a heads up to new growers that the Gridiot is not a credible source of solid pumpkin or gardening information or advise, steer clear of anything he advises…..just look at his diary….seriously…that is how you grow?

What’s yer PB Chris? Don’t think the Gridiot has broken 1K yet.

I'm stuck just under 1600 because I won't take a year off to rest the dirt.
We'll change that after a nice rest year in 2023.:)

Yeah Chris, I’m stuck at 1361 lbs I guess because I don’t use a ground cover of straw for a disease breeding ground and I don’t pour a cauldron of boiled water and miracle grow into a planting spot of burnt wood and twigs….

I just took a second look, but this time I really zoomed in. Frank That is a good call about the leaf miners. I have never really seen nor heard of them on AG's. This is a big, big world and the problems that giant pumpkin grower's face often varies considerably! My apologies for missing that the first time. I had no idea, that leaf minors on cucurbits was even a thing.

I get leaf miners every spring. the leaf miners themselves are bad, but then I get this little green and yellow finch looking bird that wants to eat them, and in doing so, shreds the leaves.
I'm using Avid to deal with aphids, leaf miners and spider mites which are three top predators in my patch.

Brandon I saw your diary with the trimmed leaf. No offence but if I left a stalk like that it would be guaranteed to rot and probably spread to the vine if I left it alone. Perhaps my patch has higher disease pressure but any unhealthy plant material has to go or else it will rot. If I have to remove a leaf I try to cut the stalk as close to the vine as possible and keep it dry.

@JBC yeah, but its one of those little surprises. Some plants would wither quickly when pruned like that, however in my experience these AG leaf stalks are longer-lasting than I would have imagined. It does feel excessive to continue walking up this mountain of a mole-hill, but my take on it-- if I may-- is that a normal level of vigilance is sufficient. Anyhow, I like cutting corners, I like not having to get out the sulfer until later in the year, if possible. I get it on my clothes, and it doesnt seem to wash out either.
Stay sane, everyone. Do not start muttering to yourself "Im surrounded by Gridiots!!!"

And there they are - The 3 Amigos - All NON-HEAVY HITTERS that contributed NOTHING to figuring out what the actual problem was. All Gritty was saying was to leave the top of the leaf stalk closed and leave (lol) it on to possibly allow its nutrients back into the plant because he observed it had a positive effect. Just sayin'. eg

The sad part is. 15 plus years ago most heavy hitters stopped coming on the boards because of stuff like this.:(
This is a local grower in my area, so I want him to have the best advice possible, so that's what I tried to give.

Every year we get one or two people that lead these growers in the wrong direction and its our job as an amazing community to help each other out.:)

All my info comes from those " heavy hitters " Wallace. Daletas, the Patons. We almost lost the Patons this year, as they could not take the crap on the boards just like this... I talk with Daletas just about every day this time of year trying to get TRUE info.

Good luck everyone and personal bests all the way around this year!!;)

Well said Frank, especially the kitchen sink part. Being proactive is better than reactive with growing, but over doctoring (throwing the kitchen sink) can cause a season's demise very fast. I know this personally from experience.

6/7/2022 10:14:58 AM

You dont have to defend yourself to a couple of porch pumpkin grower Chris, and anyone that knows you or follows your diary knows you are a heavy hitter in your area and help anyone you can with detailed help and guidance.

I dont know why EG had to resort to yelling in capital letters, but so be it.

6/7/2022 10:27:19 AM

I'm going to keep trying new things regardless of whether a heavy hitter agrees with me or not. To me thats whats interesting. Some people here ARE more competitive and enjoy a pissing contest and thats cool. Best wishes on 1500+ Northshore.

FYI, Gourdo is my neigbhor-ish and the closest grower to me. I am texting him directly. Good advice flows downhill. I am blessed to have a community of growers that have helped me for years. Growers that have had the benefit of those that came before them.

Amen Kevin!

It’s all about helping the newer grower! My mentor was mentored by Howard Dill back in the 90’s. Howard told him the one thing he wants him to do, is help others like I did you.

We don’t want newer growers getting bad info.

Thanks for texting him kevin!:)

6/7/2022 10:30:54 PM

Pass me one of those doobies that you all obviously had a bunch of, lol---Everybody was cranky and opinionated yesterday and now, it's Miller Time? Better that than what I was expecting. I can say whatevvvverr I want to on here, as was found out last week elsewhere and everyone is supposed to be OK with it.
If not, so what? - I will say this though: I do not have a porch.
From the top of this post to the bottom has been a total turnaround.
