hello all! so my dad, the genius, sprays his apple trees with dish soap if he sees pests on them. (dish soap like the palmolive stuff sitting underneath our sink) he goes out every day and picks off diseased leaves/one with bug bites on them, and then sprays liberally a mix of 50% dish soap/50% water on the leaves, especially the undersides. he has never had any severe pest problems, and now he's doing it to his cherry trees as well...he swears by it. i say 'the genius' because he knows so much bizarre old fashioned stuff that works! so...has he just been lucky, or is dishsoap an effective and organic 'pesticide'? comments?
