Kills all leaf dwelling insects on contact as well as molds and mildew and feeds foliage. Read directions for applications. For serious problems and infestations, we recommend saturation of the leaves. We recommend rinsing 24 hours later but that is up to grower (we never do). Do not saturate fruit or flowers, only mist and always spray with lights off until dry for indoor use. Outdoor anytime is fine, but early morning or evening is best. It is okay to saturate the leaves indoors or outdoors in all stages of growth. We list this product not for food only because a small segment of the population has some allergies to fish or fish byproducts. While supplies last.
