Southern Ag Insecticidal Soap Concentrate is a specially-formulated pesticidal soap designed to protect plants. The active ingredient is Potassium Salts of Fatty Acids at a concentration of 47%. This product is used to control various soft-bodied pests, including adelgids (woolly aphids), aphids, lacebugs, mealybugs, mites, grasshoppers, leafhoppers, scale insects, plant bugs, sawfly larvae, pear and rose slugs, pygidid tent caterpillars, thrips, spider mites, and earwigs, as well as controlling whitefly and powdery mildew. It is suitable for use on vegetables, fruit and nut trees, citrus, berries, ornamentals, shrubs, flowers, and trees located in homes, gardens, and greenhouses. The product can be used up to the day of harvest. When applying, ensure the spray is directed to achieve control, as it is a contact killer that penetrates the bodies of pests to disrupt membrane and cellular function. Users should avoid spraying in calm weather or when rain is predicted within 24 hours to ensure effectiveness and prevent runoff. Always shake well before use.
