I see they have Tebuconazole. I have only ordered from them the one time. They shipped quickly with no problems. http://epestsolutions.com/Tebuconazole-36F.html/ I have no experience with fungicides. I purchased the Captan with intent to use it to prevent mildew during germination in closed dishes. (No fungal problem in the open-to-air sown seed, only when enclosed in a dish.) But the Captan container says not to use it on seeds. I read in a PBS discussion that some do use Captan on seeds so if you have a protocol for that I would be grateful, especially what concentration to mix. I got the dry powder. Thank you, Gastil In Santa Barbara, California, where we have rain and rainbows today, and tiny bulb seed sprouts.
