Where there's green there's hope. I don't toss anything that isn't obviously permanently dead unless I have a positive virus test and it's not something that I want to nurture.
You can buy test kits from Agdia. Also Rega Biotech in Taiwan sells them CymMV + ORSV | Plant Virus Rapid Test | Regabio, cheaper per test but one must by 50 tests (if you can find others to share in the purchase, can still be the way to go)
