Torry from Machesney Park writes
There is not a particular time of the day that is necessary to spray D-Fense SC as long as it's sprayed 24 hours before any expected rain and avoid spraying in the heat of the day to avoid any foliage burn. We recommend spraying in the early morning or later in the evening and avoid spraying any blooms since that is when pollinators are active.
