Promotes the health and vitality of trees and plants. Neem has long been recognized for its antifungal, antibacterial and antiparasitic properties. Neem’s azadirachtin content deters a wide range of insect pests, disrupts their life cycles, and often leads to their mortality. For a processed neem product registered as a pesticide, see AzaMax.
Spray for full leaf coverage every 7–10 days as needed for suppressing disease or insect pests. Research indicates that pest and disease management is enhanced when neem oil is mixed with Karanja oil.
To make a spray, mix 1 oz warmed neem oil (or ½ karanja and ½ neem oil) with 2 tsp biodegradable dish soap, and add to 1 gal lukewarm water. Avoid spraying when bees are pollinating as neem is harmful to larvae and developing grubs. MOFGA
Neem and karanja oils can be used topically on livestock and pets as a parasiticide and for general skin care. Studies show neem can control lice, mites, fleas and other ectoparasites as an antifeedant, landing repellent and fecundity reducer. Aside from its better-known antifungal and antibacterial properties, neem oil also has anti-inflammatory and analgesic qualities that make it an effective skin therapy for mammals.
Karanja oil shares many of these pest- and disease-fighting properties and works synergistically with neem to improve its efficacy. Mix 1 oz neem oil (or ½ oz neem and ½ oz karanja) with ½ gallon of warm water, using soap to emulsify. Massage into animal’s skin, fur or fleece, keeping it away from eyes. Let sit for half an hour and wash off. Repeat every 2 weeks or as needed. We use it on our sheep after spring shearing and observe a lasting effect through the grazing season.
One cautionary note: if ingested in significant amounts, neem oil may have a negative effect on conception.
