Leaf curl
 

Noticed this when I got home today on many of my plants. I mulched with pine bark mulch and sprayed daconil on them yesterday afternoon. Thats the only thing I have done different since they went in the ground. Im not sure if its a problem or not. Any Ideas?

I think leaf curl is a physiological problem which is the plant is still working out how to distribute all the nutrients throughout the plant. I do believe it will go away of its own accord.

Curious if you are following Earl's hole planting method (mix 1 handful of TomatoTone 4-7-10, 1 handful of Epsom Salts, and 1 handful of Bone Meal along with 10 lbs of Compost in with the cubic foot of soil where the plant will be) or some other method?

Didnt follow his method. I ammended the soil with cotton burr compost, ,manure and some alfalfa pellets. I did mix in compost, tomato tone and epsom salts with the dug out soil for each plant. As for the leaf curl, most of my plants looked better this morning, I just overreacted

I bet it was something in the daconil solution.

IIRC the first list of soil amendments you put
in months ago (so the manure is surely composted
enough by now to not overstimulate the plants even
if it was fresh when you got it). The only thing in the
second list that the plant would have found shocking
is too much Tomato Tone, and why would they wait
until after you mulched and sprayed to react to that?

Pine Bark mulch wouldn't cause an abnormal growth
reaction unless it had some kind of industrial waste
or similar infused into it (not likely).

A chemical spray, OTOH, could have pretty much anything
in the "inert ingredients." (I am guessing that you
probably followed the directions on the bottle, so it
likely was not an overly high concentration of the Daconil
solution that caused the leaf curl.)

"Shake well before using." (?)

This can be an environmental reaction, too.
Sudden change in the weather? They generally
recover from weather-induced leaf curl without lasting
effects.

Thanks for the link, good read

Ami,

I rapidly scanned that Manitoba site and I have a problem with it, in general.:)

And that's b'c they're attributing all means of leaf CURL to leaf ROLL.

Leaf Roll is understood by many to be a temporary situation found when plants are young and root and foliage mass are not in balance which causes a temporary stress. It's completely reversible as the plants mature.

While the reasons for leaf CURL are many and varied ranging from most hybrids that do have curled leaves normally, to general stress as in too cold, too hot, too wet, too dry, too much of a fruit burden which can also cause leaf curl, as well as many viral diseases, and on and on.

But Daconil has never been known as something that causes leaf curl, from all I've read and also with my former long time experience with it as well as the experience of all my commercial farmer friends over a very long period of years.

I Misunderstood Carolyn's reply and when I looked up 2,4-D I saw a referance to Daconil but it is not in the ingredients. My mistake. Suze, thanks for bringing it to my attention. Got a little confused. Ami

[quote=amideutch;49876]Carolyn, I was wondering what Daconil had to do with it till I looked up 2,4-D. They discribed 2,4-D as a Hormonal Herbicide so I didn't see the connection. So is 2,4-D only a fungicide or is it a combination of a hormonal herbicide and a fungicide. As they referenced it for weed removal which is what herbacides do what is the Daconil's part. I can see leaf curl caused by the herbacide as they discribed it as I have seen it when I used "Roundup" one time to close to a tomato bush not knowing at that time what the consequences would be, but found out in a hurry.

Ami, I read the referenced article, but I don't understand your interpretation of it. 2,4-D aka Roundup, aka glycophosphate is not a fungicide. Daconil aka chlorothalonil is not a herbicide. Two completely different products/chemicals.

Just to keep things straight, 2,4-D is not at all related, structurally, to Roundup (glycophosphate), though both are herbicides.:)
