Per the product label, you can repeat applications of Dr Earth Vegetable Garden Insect Killer RTU every few days as needed. Apply early in the morning or late in the afternoon to avoid leaf burn. May be used on edible crops up to the day of harvest. Keep in mind that this is a contact kill only, so you will need to get thorough coverage of the insects for maximum kill.
Dr Earth Vegetable Garden Insect Killer Rtu 24 oz can be used up until the day of harvest. We would recommend letting the product dry on the plant before consuming it if you are harvesting them that day. Be sure to wash the plants well before consumption.
