In this episode Dr. Russell Sharp explains insecticidal soaps—how they work by physically breaking down insect waxes and spiracles, acting as contact killers without systemic residues.
He covers practical use: effective mainly on soft-bodied pests and powdery mildew, the need for repeat sprays (every 5–7 days) during infestations, and precautions to avoid phytotoxicity and high temperatures.
Tips for choosing products focus on plant-safe, sodium-free formulas (potassium/ammonium alternatives), tank-mix compatibility, and organic options like Yucca Extract.
