It took us six months after identifying with a lab test to rid the plants of fusarium oxysporum. Sending plant samples to lab to see if it's truly gone or if our beneficials are just keeping it at bay. It took a major change in our practices at our grow spaces to get plants growing with vigor...

Use Physan 20 to sterilize everything, even soak your seeds in a mixture of it before popping. Cannot remove it from cuts without tissue culture lab. Shower, new clothes, shoes etc every time going between grows. I'm building a new spot also with UV lighting in my entryways that kills spores...

I've only had a few plants wilt in a few years. Major signs are around week 3, once PK starts to be increased. That added stress makes the plant look unhealthy with deficiencies and yellowing. Also get the pink stems like P or mag deficiency. If you ever see a plant where all the leaves are...

Rascal's Fire OG has done well for me. Any strain that grows quickly and is hearty. Most og's don't do well against fusarium. I use the subdue and heritage weekly rotating between them in veg. I feed bennies a few days after drench each week. Keep feeding the bennies in flower also.

I'm in coco, those are drench application rates. I don't know how effective sprays are for fusarium. How do you know you have fusarium? Lab test or seeing symptoms?

These are strong doses, maybe start with half strength PHC Colonize AG from Sym-Agro @ .5 grams/gal Subdue .5mL/gal Heritage .5 grams/gal

I've found certain strains that are fusarium resistant. Minimizing environmental stress and drenching with a lot of bacteria products is helping. Subdue and Heritage create a noticeable difference in plant health also. This disease is everywhere and spreading quickly, just have to learn how to...

I sent a sample to the lab as well and tested positive for fusarium oxysporum. Yields had dropped 50% and it took me a couple years to figure out exactly what was causing this. Rarely have I had plants wilt, but the pathogen creates symptoms that resemble nitrogen toxicity with leaf curl, and...
