triazicide, then rain. Reapply?
I've been unable to spray my fruit trees until yesterday. (Out of town, then wind.) The Cherry was in bloom when I left town about 2 weeks ago. I'm new to this, but I'm pretty sure the Cherry tree has aphids. Yesterday evening the wind died down last night about 8 pm so I sprayed with Triazicide. Despite the forecast, it rained last night. Weather.com says it didn't rain. My rain gauge says 0.01". So probably fairly light. Do I need to spray again?
