I do not remember why, but I planted this one in this pot months ago. I know he was rootless, so I did not water him for months. I did a little tug, he felt secure, but floppy. I watered him, I remove the top layer of pumice to see how best to secure him, before putting him back.

He is floppy because, it had only rooted on one side. Then I noticed this, what appears to be fungal band across the leaves, as well as one spot higher up on one leaf.

I removed three leaves, but I see small spots on some of the inner leaves. I know he is now garbage.

I would like to know what it is.

Of course the first time he is watered in months, I did a gang tub. One of the other plants was also a Agave. If I knew what it is, I can put together a preventative plan.

Until then I will do the following,

Bath in H2O2

2 day later - inoculate with mycorrhizal fungi

1 week

Start a every two weeks rotations of

Baccilus subtilis first then Trichoderma harzianum in two weeks

I do have some chemicals is that is needed
