So many good answers already. I'll just second one of the earliest replies that pointed out the diversity in yards is much much greater than what we have in our native habitat. I spend a fair amount of time in some mountain locations here. 4 species of trees for miles around: two oaks, a fir and a cedar. My little HOA, which I walk extensively with my dog, has that beat with its coral, carrotwood, ficus benjamina, rubber tree, brush cherry, juniper, podocarpus (several species), silk floss, queen palm, pepper tree (two species), canary island palm, fan palms, hong kong orchid, trumpet tree (brugmansia?), jacaranda, eucalyptus (2 or 3 species), bottle brush, bradford pear, sycamore, liquid amber, 3 or 4 different pines, bronze loquat, catalina cherry and a couple I haven't ID'd. And that's just the front yards in a fairly boring area. I love driving around older neighborhoods where there's been time for the owners to replace things and you see twice or three times the tree species and a lot more fruit trees. Its also worth pointing out that some of the common landscape plants have some decent grafting potential: hawthorn, pear, bronze loquat.

The label should tell you if you need to wait a certain number of days to harvest. IIRC, Daconil has no wait time to harvest when used on tomatoes. It would be almost impossible to avoid spraying your fruit if you're spraying correctly. Remember that you have to spray all stems, foliage (both top and underside), and preferably also all developing fruit as well. If you can do that and avoid getting anything on mature fruit, you are very talented.

The rest of the plant actually look really healthy except for the few yellowing leaves and stems. You’re not really going to know the full extent until you can view the roots but are you noticing more and more stems become mushy as time goes on or is it just this 1-2 and nothing before/since? I think if its a recurring issue your best bet is to have a peep at the roots, if there’s any mushy or brown roots, cut them off and repot in a different medium, add some perlite to help with drainage and aerate the soil. If the roots are coming out of the bottom too it sounds like it needs a larger pot to stretch its legs, I know you don’t have access right now so if you’re confident you can always prune the roots and place back in the same pot but otherwise a larger pot will really benefit the plant. Hope this helps :) Chloé

It’s most likely a fungal infection, I’ve had them with mine before. Cut the infected leaf off, otherwise it will just keep spreading. Also, stop misting it. Snake plants HATE water on their leaves - it can lead to fungal infections very quickly. Good luck!
