I've had good luck with foliar application of potassium bicarbonate. Also adding potassium silicate to their water (1/2t/g) seems to help, there's research backing that up and plenty of anecdotal evidence.My wife's gourds are getting whacked today, she's been told...even Regalia can't do miracles.
That could be Botrytis also, looks vascular.
