Therefore, insects do not become resistant. Organic-conscious, enthusiasts and weekend gardeners will love using this horticultural spray oil because it kills without using harsh chemicals. Plus, the unique refinement process permits use through growing and dormant seasons, but most importantly allows you to use year-round. It can be used on home gardens, houseplants, landscapes and fruit trees. Also, Ultra-Fine is odorless and safe to use up to harvest time.
Protection can last for up to two weeks.
For best results, spray in the early evenings and mornings when you are apt to have the most insect activity on plants. Ultra-Fine is available at most Ace Hardware, True Value, Sears and independent lawn and garden stores. A one-quart bottle makes up to 25 gallons of spray.
