New growth wilt and other weird things

[Shell]

I destroyed the plant today. I think you were spot on with your diagnosis! I read what I could find, and it pretty well ticked all the boxes. At least it hasn’t spread..yet. I’m going to treat the soil there with some bacteria. Not a cure, but it won’t hurt. And I definitely won’t be planting in that spot in future. Thanks for your help

Thank you for commenting.I just read the link you posted....I really hope that this isn’t Fusarium, as I gather it’s untreatable. Oddly enough, I do have clay soil to which I add mushroom compost, composted manure, perlite, worm castings, peat, etc to “lighten” the soil and give good drainage. I have grown in this area on and off for over 20 years...and this is the first time I’ve ever seen a plant with these symptoms. I’ll have to read more ...ie, is this contagious ? If it’s soil borne, can I treat the soil over winter with something? What should I do now???

Indeed, I'm thinking Fusarium wilt.

If those were my apples, I'd say Fire Blight. So I'd start with blight. Fungus or bacteria.

This is an outdoor grow. Literally overnight, new bud sites(not all) appeared wilted and have silvery tips on leaf ends on newest growth. Ends are discoloured and newest leaves are thin and curled inward. All other plants in same area, are fine. Amended soil with organics, PH neutral rainwater, fish emulsion x1 weekly, molasses fed twice a week. The other plants are thriving, as was this one, till yesterday.

We are in drought and have had extremely hot days, and winds. (At least, unlike some neighbours, we haven’t been burnt out.) I have checked the leaves with magnification and can see no signs of insect infestation. There is some interveinal yellowing on newer droopy leaves. Older leaves are green, robust and healthy.

I’ve never had a plant with this, and am at a loss as to what is causing it. Has anyone seen this before? I’d hate to lose this plant as it’s a strain I’ve been really keen to try. Please help! Any and all advice would be appreciated.
