Thanks for the information however I fear it has spread to all 3 varieties and is moving fast. I had hoped the Purple Haze would not succumb but I found it there. In years past it has consumed the tops in 3 or 4 days but at least the RG and YG have set tubers of a fair size. I will post more photos this evening...
I’d give it a try on at least a few plants. Can’t hurt anything. I’ve picked 25-30 gallons more tomatoes that i’d have picked had i not sprayed.
