I've been talking a lot about HpLVd these days on the forums and have been reading up on the various viroids affecting agricultural crops, and I found one really interesting thing. Vircon S and 10% bleach solution are two of the most effective ways to disinfect tools contaminated with the viroid, but one other substance is almost equally effective: a 20% dry nonfat milk solution. Now, you can't just cut an infected plant, dip your scissors in milk, and then move onto the next plant. Honestly, I wouldn't even do that with a strong bleach solution-it's best to let the tools soak for 10 min. But the nice thing about having dry nonfat milk is an option is that, for home use, you don't want an open container of 10% bleach around-that will make your house reek for ages. Milk on the other hand is totally inoffensive. It's also economical if you just mix up enough to soak your blades in-20 grams of nonfat milk to 100 ml water, for example. Here are the two studies I'm talking about:

https://apsjournals.apsnet.org/doi/10.1094/PDIS-09-14-0929-RE. I just find this to be extremely interesting, I had no idea that milk is a potent antiviral, but it makes sense doesn't it?
