I use Merit WP and rotate it with Orthene WP. I have enstar that I use as a back-up. I'll have to spray in the next couple of weeks.Ugh, don't remind me of scale! What do you use to control it in your greenhouse?
About and hour SW of Nashville, TN. Where are you. I end up doing work near Dayton now and then, and visit with Lowel PatrickYou inspired me to go look at my garden in central Ohio.....no sign of crocuses, but I did see some snowdrops pushing thru and showing their buds. They should be up by next weekend. Where are you located?
