safe insecticide for fruits trees
my peach and cherry trees are at petal fall, soon i would like to apply an insecticide to protect from fruit worms and other insects. i've already applied fungicide. i've heard that malathion and sevin are very toxic. does anybody know of a less toxic efficent insecticide. either organic or synthetic.
i have rotenone powder but don't know the ratio to mix it for a hand sprayer. any suggestions?
