Systemica® is a unique all-natural formula that works as a two-in-one spray and root drench solution. Use as a foliar spray for leaves and branches, or soak the soil for root drench. It contains rosemary and clove botanicals that kill and repel insects. Systemica® works on contact while it’s also absorbed into the plant’s cell walls, just like water, creating complete and total protection. If an insect starts to feed on the plant, Systemica® causes the pest to move on or die. People and pet safe.
