The spot of rot you see, generally brown, open up the bud at that point and look for little black specks and the nasty green caterpillars that produce 'em. In my experience, "bud rot" is generally caused by moisture from the feces and general activity of the worm. Are you spraying them with anything for worms?
You could harvest, you could also try cutting out the infected plant matter. This has worked for me before...
brah, "
bud Rot" for the main part is not caused by catapillars. The catapillar damage you are talking about is caused by the little bastards grinding on plants!. Sure their turds do damage, but nothing like what their mouths can do. His concern is all the moisture from the rains on his buds. He said nothing about catapillars!!??!? Every long season I throw roughly a quater to a half pound of "buds" away due to "
bud rott". Why just yesterday I threw away about an ounce and a half. I've tried everything to stop the "bud rot".
Cutting away the infected area is not a good idea. Removing the entire section, or plant would be highly recommended. "
Bud rot", is basically made up from spores. Once this gets on your hands,knife, tools, etc., etc.. watch out!
After treating each infected plant, you need to wash your hands & tools otherwise you'll have opened up a can of worms that will ruin your season.
