Yet another question from a new grower: When pruning vines, say cutting vines that grow off of secondary vines (are those tertiary vines?) how do you treat the area that you just cut?

For the necessary "standard pruning" try to remove the tertiaries as soon as possible, then there´s no need to treat this area with anything. For the treatment of larger areas (after cutting off strong vines) some other growers can give you hints at how they prefer to treat the cuts.

I use a little sulfur powder if I have to cut a big leaf stem or make a major vine cut.

yes the vines coming off of the secondaries are tertiaries

you can pinch them off when they are barely big enough to see, but if you do that make sure you get it all or it will start growing again (even if buried).

we spray all wounds (whether we created them or they occurred some other way) with peroxide and then dust with captan. some people use rubbing alcohol instead of peroxide, and some use sulfur powder instead of captan.

the spray will kill any bacteria, and the fungicide prevents fungus from entering the wound.

Good Luck

Cecil, is your peroxide the ordinary 3% hydrogen peroxide full strength or diluted?
I think I have a few tertiary vines to prune & it won't be long before I will need to terminate & bury some secondary vines.

we actually buy 27% (Baquacil pool oxidizer) and cut it with distilled water to 6% for normal everyday use. If we discover a problem spot we will use the 27% straight out of the bottle.

CAUTION!!!
Use gloves and safety glasses when handling the oxidizer, it will give you a chemical burn!

Before cutting make sure your cutting tool is thoroughly washed in soap and water. As with any garden pruning, I recommend doing this in the morning (never during peak periods of the day). Never mess with the plant's leaves, vines or fruit during or immediately following rain. These are opportunities for disease transfer. Hope this helps!
