my tomatoes have "late blight"

black leaves and stems, fruit is looking good, but the foliage and stems (especially around the joints) have the blackness/rotting. I wonder what caused this..maybe the drouth we had, or maybe my soil needs to be left alone for a few years? i was wondering if anyone had any input on Tomato blights because i would hate to relocate my garden, i like where it is

Ive goggled Late blight, and I find it rather confusing.

i think i have the same problem. it starts from the ground up and one by one leaves/stems start to die off. idk if it is natural kind of like with MJ but i am worried if will effect my tomatoes or worst kill the plant. i think it might be fungal or a blight.

chicken bone nowison!

i would say scrap this years crop and treat the ground with one of these if you plan to crop any solanum (nightshades such as potato/tomato) in coming years:
Use of fungicides

Fungicides for the control of potato blight are normally only used in a preventative manner, perhaps in conjunction with disease forecasting. In susceptible varieties, sometimes fungicide applications may be needed weekly. An early spray is most effective. Metalaxyl is a fungicide that was marketed for use against P. infestans, but suffered serious resistance issues when used on its own. It is strongly advised to use metalaxyl along with carbamate compounds, or the especially effective synergistic Cymoxanil and Mancozeb combination as it is effective at managing metalaxyl resistant strains.[SUP][14][/SUP]
In the past, copper sulfate solution (called 'bluestone') was used to combat potato blight. Copper pesticides remain in use in rare instances on organic crops.

(from wiki on late blight)I know someone who fought it off early with Cu but you might be a bit far along so I preach caution.

also find out if anyone around you has it, if they dont treat properly you will surely see it again (wind) also every time you mess with it you are spreading it

dank. may I ask you to clarify what you mean by this?

^ like how some of the bottom leaves start to yellow and fall off

idk what the fungus is but it is a fungus. they all work their way up from the ground from leaf to leaf. cut off anything infected and then another two or three leaves higher to be sure. the thing with fungi is you can't save the infected leaf just keep it from spreading. and ima guess any fungicide is better than nothing but put paper bags around your clusters of maters to keep the shit off the fruits. if you send a sample to your county extension agent they'll tell you exactly what the disease is. extension services usually work hand in hand with a local university. google agricultural extension service in your county. they are a wealth of information.
