Sabadilla is considered among the least toxic of botanical insecticides, but its dust can be highly irritating to the eyes and can produce sneezing if inhaled. The active ingredient is an alkaloid known as veratrine. Sabadilla, another botanical insecticide, is derived from the seeds of the sabadilla lily.

Choose alternate pest control measures when treating insects on roses. It's commonly used to control aphids, thrips, spider mites and other sucking insecticides on most vegetables, some fruits, flowering plants and ornamental shrubs and trees. Nicotine kills insects by interfering with the transmitter substance between nerves and muscles. Nicotine sulphate is sold as a 40 percent nicotine sulphate concentrate under trade names that include Black Leaf 40 or Tender Leaf Plant Insect spray. (Wear gloves when applying it, follow label directions and keep pets away from application areas.) It breaks down quickly, however, so it is legally acceptable to use on organically grown crops. It's also one of the most toxic to warm-blooded animals and it's readily absorbed through the skin. Nicotine is extracted from tobacco or related Nicotiana species and is one of the oldest botanical insecticides in use today. Neem also can be purchased under the trade name Bioneem (by Safer Products). The treated insect usually can't molt to its next lifestage and dies. Margosan-O works as an insect growth regulator. This product is labeled for use on ornamentals, foliage plants, trees, shrubs and other non-food crops. It is not highly toxic to mammals.Ī neem-based pesticide, Margosan-O, has been shown to control gypsy moths, leaf miners, sweet potato whiteflies, western flower thrips, loopers, caterpillars and mealybugs. The use of this compound is new in the United States, but neem has been used for more than 4,000 years for medicinal and pest control purposes in India and Africa. This tree supplies at least two compounds, azadirachtin and salannin, that have insecticidal activity and other unknown compounds with fungicidal activity. Neem is a botanical pesticide derived from the neem tree, a native of India. Botanical Pesticides for Organic Farming: The pesticides discussed below are appropriate to include in IPM programs. IPM relies on a variety of pest control means rather than on one product or method. The use of botanical and mineral-bearing pesticides, even though some are toxic, also can be incorporated into an Integrated Pest Management (IPM) approach to growing crops. These chemicals may be highly toxic, but they break down more rapidly than common chemicals, such as the Sevins, Malathions and 2, 4, Ds. Organic gardeners can use certain pesticides- chemicals that are derived from botanical and mineral-bearing sources.

If we think organic gardening means vegetables free of any chemical pesticides, we don't have the story quite right.
