Big plants dying suddenly

[mendo-local]

What is fusarium and how do you deal with it? I usually lose a few random branches but would love to know if its preventable or treatable. ..

I had Fusarium indoors once, parts of plants would die like in the OP pics, affected branches were grey in color and dry as a bone. It's like it stops any fluids from traveling up the stems.

In my case it was due to no/low air movement in my room.

I agree with fusarium. It's a bitch. Had my soil tested positive for it last yr. my ladies are doing ok so far, but one of the things I was told was to not damage the stalks at all, and try avoid getting too much water on stalk. I also hit with actino-iron.
Only way to be sure to get rid of it is by either sterilizing the soil (which isn't really possible, or replace soil.

fusarium is present in all soils though... you need to test the plant tissue.

It's kinda' like herpes. A clone can be infected but never show, same with soil. Most outbreaks tied to warm temps, high nitrogen & overly moist. Everything a plant usually loves. Same as fucking a hot ass dirty chick till your dick blisters and falls off lol. Your mileage may very, but that's fusarium in a nutshell lol.

I'm having a very similar problem myself. Found this girl laying on her side today, propped her up and this is what she looks like now.

Not sure if it's a combination of underwatering/being trampled (doesn't appear to be trampled, we had a heavy rain this morning but I didn't see any tracks going over the plant) (my deer fence was breached by a deer recently) or if it's some sort of root disease.

Usually my few branches that die do it quick. This year I have 2 different branches that wilt In The morning but by mid day start sucking up water an look good to go. No idea what to think. This has been going on for a month or so and I've almost chopped them numerous times . Guess I will just see what happens?

Mendo-local - you are describing fusarium. Rock it till the wheels fall off.

Someone doesnt like you or your plants. I would guess sabotage.
If not.....then you have serious issues. Maybe ants eating the roots, fusarium disease,
Gophers, or Sabotage. Thats my guess.

Happening to me as well outdoors this year.

Branches wilting and dieing left right and centre. I put it down to the unusually humid weather this time of year. Fusarium, verticillium or similar pathogen.

Please keep us updated as to how it progresses. Wishing you all the best!

Peace

I never heard of this happening before. That really sucks guys. I dug my holes in hard packed clay w/ cement pieces in the ground, and filled it with a FFOF soil and Chunky Perlite mix.
Im sure the hole holds water like a mofo. I put the plants in 45gln growbags above the holes filled with the same mix. Maybe thats whats stopping them from becoming overwatered?
Weve got rain every 3 days it seems this year. I havent had to water 1x yet and my plants are flowering now.
Im surprized I havent had any issues yet.

I truly hope you get this fingered out. Thats the worst.

I'd dig up a dead plant before it dries out all the way. It's real difficult to diagnose problems if you wait. Slime dries out and eggs and bugs are hard to spot.

I lost two monsters this year, but its pretty normal to lose one or more a year. Pretty sure most farmers experience plant death.

no way to tell for certain without a lab test but looks like phytopthora to me.. especially the black lesions in the stem... tis the season as it usually appearsoff late july early aug

 

[furrywall11]

yep, fulsarium wilt. watch your watering, use actinovate every week foliar and root drench, myco stop, more mychorizae. any another suggestions?

 

[Backyard Farmer]

Make a new garden with new soil and grow veggies in your current ganj gardens for a year , it isn't the best to keep growing the same crop in the same holes over and over again.

Next year going to focus on dep and do 25 in 10x10 mounds with the spacing they should be getting.

looks like overwatering, got this on a rene plant that was on a dripper. I only lost one plant, my roots had grown out of the pots bottom and into the ground below big time{roots saying get me outta here yo to wet}

 

[Fly by Night]

Old soggy feet gotya this time...we'll be back to show em who's boss homie!

Our plants have been doing beautifully throughout the season. This photo was taken today. Almost all the plants look like this.

I've had the same thing, and it turned to be something with the roots. Probably some kind of fungus. I think it can be prevented by the continuous application of mycorrhizal fungi or trichoderma, which also protects roots.

Thank you all so much for your time and consideration!!!!

I apologize for not updating the progress.

No signs of any rodents. No damage to the bottom of the stalk.

The thought of sabotage definitely crossed my mind, but since it was a small fraction of the garden I think/hope thats not it. Our location is secure, and we keep a tight watch on things.

We hit them with activonate within a couple days of seeing the first problems, and then we got some myco stop into the soil a few days later. We also went about 10 days only spot watering thirsty plants to make sure that we got them good and dried out.

Were now back to a regular, reduced watering routine. Thankfully no other plants have shown any signs of stress or disease.

How does one go about getting the plant tissue tested for fusarium wilt?

Thanks again to everyone for sharing

go to the most infected area so it will be easier to identify. take a branch and then cut her in half. look inside the stem and if there is brown or blackish spots (it appears as spots on a cross section of the branch but they travel all the way up parallel with the branch. https://ipm.illinois.edu/diseases/rpds/650.pdf
